Bosch fully automatic coffee machines have been offered in numerous generations over many years. From older Benvenuto models through the widely used TES fully automatic coffee machines and the Vero family to modern freestanding and built-in machines, their design, operation and individual assemblies differ considerably in some cases.
Nevertheless, the following applies to many defects: the complete fully automatic coffee machine does not have to be replaced. Numerous mechanical and water-carrying components can be replaced or repaired individually. At NEW-Kaffeevollautomaten you will find selected Bosch fully automatic coffee machine spare parts for this purpose.
Depending on the machine generation, our range includes components from areas such as brewing unit, grinder, pumps and fluid system, seals and O-rings, valves, hoses and connectors as well as further repair and wear parts.
Anyone searching for Bosch spare parts should first take into account that the Bosch brand name covers very different fully automatic coffee machines.
Older machines include, for example, models from the Benvenuto series with TCA model designations. These were later followed by numerous machines with TES model numbers as well as product families such as VeroCafe, VeroBar, VeroAroma and VeroSelection.
Current machine generations include the VeroCafe family as well as Bosch Series 8 built-in fully automatic coffee machines with CTL model designations.
These generations differ considerably in some cases in terms of brewing unit, grinder, pump, heater, valve technology, sensors, milk system and electronics.
For this reason, the designation “Bosch fully automatic coffee machine” alone is not sufficient for reliable identification of a spare part.
Bosch uses the so-called E-Nr. or product number to identify its machines uniquely.
It consists of letters and numbers and frequently includes an index for the specific machine version after a slash. An example of the principle would be a designation such as TES50351DE/13 or CTL636ES1/04.
This index in particular can be relevant for spare-part allocation. Two machines with almost the same model designation may come from different production versions and contain individual modified components.
Before ordering a Bosch spare part, the complete E-Nr. on the rating plate should therefore always be checked wherever possible.
The E-Nr. is located on the rating plate of the fully automatic coffee machine. The exact position depends on the machine design.
Depending on the model, the rating plate may be located, for example, in the machine area behind a service flap, around the water tank, on a side or rear surface, or, in the case of built-in machines, within the accessible machine area.
In addition to the E-Nr., further information such as the FD number, serial number and production information may be present.
For spare-part searches, the complete model designation including the index is particularly important.
The Bosch Benvenuto machines are among the older fully automatic coffee machines from the brand. Typical machines from this generation carry TCA model numbers.
A well-known example is the series around models such as TCA6001 or TCA6809. Spare parts continue to be sought for these older fully automatic coffee machines because numerous machines are still in use.
Classic wear issues often occur particularly on older machines: seals age, pumps lose performance, grinder components wear or valves begin to leak.
Whether a repair is worthwhile depends less on the age of the machine itself than on the specific fault and the overall condition.
A particularly widespread generation consists of Bosch fully automatic coffee machines with TES model designations.
These include, for example, machines from model ranges such as TES5, TES6 or TES8. Numerous different variants exist within these series.
Designations such as TES50251, TES50351, TES50621, TES60759 or TES80353 therefore represent not only different equipment levels, but in some cases also different technical generations.
When carrying out repairs, you should therefore not search exclusively by product name such as “VeroCafe” or “VeroBar”. The complete Bosch E-Nr. is considerably more reliable.
VeroCafe is one of Bosch's well-known product families for fully automatic coffee machines. The designation has been used across different machine generations and is also found on current models.
Depending on the machine, typical wear and repair areas include brewing unit, grinder, pump system, valves, seals, water system and milk system.
As older and newer VeroCafe versions differ technically, the specific model number should always be checked here as well.
You can find suitable available components in our Bosch fully automatic coffee machine spare-parts category.
The Bosch VeroBar series are also among the frequently repaired fully automatic coffee machines of older TES generations.
The machines feature the combination typical of modern fully automatic machines: an internal grinder, removable brewing unit, water pump, heating system, valves and electronic control.
Particularly after many years of operation, signs of wear can occur on mechanical components and water-carrying connections.
Precise diagnosis is important here. Weak coffee, unusual water loss or a lack of water flow cannot automatically be attributed to a single assembly.
The VeroAroma and VeroSelection product families are also part of the Bosch fully automatic coffee machine range.
Depending on the machine version, they differ in equipment, beverage programmes and operation. Technically, however, they still have the central assemblies of a fully automatic coffee machine: grinder, brewing unit, water pump, heating and fluid system.
When carrying out repairs, it is important not to search only by the sales designation. The exact E-Nr. enables considerably better identification of the spare part actually installed.
More compact or newer Bosch fully automatic machines such as VeroCup and current VeroCafe models also contain replaceable or serviceable components.
However, spare parts from older TES generations should not automatically be transferred to newer machines.
Changes to the brewing unit, grinding system, pump system, connections, electronics and sensors can mean that components which look similar externally are not technically compatible.
For Bosch in particular, it is therefore worthwhile to consistently search using the complete machine identification.
In addition to freestanding fully automatic coffee machines, Bosch also offers Series 8 built-in fully automatic coffee machines.
Well-known machines carry, for example, model designations from the CTL636, CTL836 or CTL918 ranges.
Built-in machines differ significantly from freestanding fully automatic machines in some areas. In addition to the actual coffee-related assemblies, the machine front, drawer system, internal containers and installation mechanism, for example, must also be taken into account.
Inside, however, central components such as the brewing unit, grinder, water pump, valves, heating and milk system continue to operate.
Bosch and Siemens household appliances belong to the same corporate group. Numerous fully automatic coffee machines from both brands are therefore based on related technical platforms.
This explains why certain components can be used both in Bosch and Siemens machines and, in some cases, in further brands from the same technical machine family.
Depending on the version, these may include, for example, pumps, valves, seals, hoses or other components of the fluid system.
However, the technical relationship expressly does not mean that every Bosch spare part automatically fits every Siemens machine.
Even within a shared machine platform, production year, connections, software version or design details may differ.
On certain fully automatic coffee machines and built-in machines, individual components may be used across different brands.
As a result, spare parts sometimes contain compatibility information for Bosch, Siemens, Neff and Gaggenau.
This is useful when searching for spare parts because a technically identical component does not necessarily have to be listed exclusively under the Bosch brand name.
Nevertheless, the specific product allocation remains decisive. An overlap between brands alone is not sufficient to ensure compatibility.
The Bosch brewing unit or brew group performs the actual mechanical brewing process.
After grinding, the coffee grounds enter the brewing chamber. There they are compressed and then hot water flows through them.
After dispensing, the brewing unit opens again and ejects the used coffee grounds into the grounds container.
This process is repeated with every coffee. Pistons, guides, seals, brewing chamber and drive mechanism are therefore moved very frequently over the service life of a machine.
On many Bosch fully automatic coffee machines, the brewing unit can be removed from the machine.
This enables mechanical cleaning of coffee grounds and deposits that may not be completely removed by automatic rinsing programmes alone.
The brewing unit should be cleaned in accordance with the respective Bosch operating instructions. On many machines, it is rinsed under running water.
Cleaning agents or dishwashers should only be used if the manufacturer expressly permits this for the specific assembly.
Loose coffee residues can also be removed from accessible areas inside the machine.
A stiff brewing unit can have different causes. Contamination, dry sliding points, damaged seals or mechanical wear often play a role.
Before parts are replaced, the assembly should be thoroughly inspected and cleaned in accordance with the machine instructions.
Suitable food-grade silicone grease for O-rings and seals can be used at sealing or sliding points intended for this purpose.
A damaged or heavily worn seal, on the other hand, should be replaced and not simply greased more heavily.
A modern fully automatic coffee machine contains numerous seals and O-rings.
They are located, for example, on the brewing unit, hose connections, valves, pumps, couplings and other components of the water path.
Not all O-rings perform the same function. Seals can differ in terms of dimensions, material, temperature resistance and mechanical load.
An O-ring that looks similar is therefore not automatically a suitable replacement.
Seals in a fully automatic coffee machine are exposed to various stresses. These include temperature changes, pressure, water, mechanical movement and ageing.
As a result, an O-ring can become harder over time, lose its elasticity or become mechanically damaged.
Possible consequences include small leaks, water loss or an increasingly stiff plug-in connection.
During repairs, therefore, attention should not only be paid to the visibly defective component. Adjacent seals can also be responsible for the fault.
At designated sealing points, a thin film of food-grade silicone grease can make installation of an O-ring easier.
The grease reduces friction between the seal and mating surface and can prevent a suitable O-ring from being unnecessarily twisted or mechanically stressed during assembly.
Our 6 g version is particularly economical because only a thin film of grease is normally required at corresponding sealing points.
You can find further pack sizes and bulk quantities in our food-grade silicone grease category.
The grinder of the Bosch fully automatic coffee machine grinds the coffee beans immediately before brewing.
Grind size and grinding quantity influence how the water subsequently flows through the compressed ground coffee.
Bosch uses different grinder designs in different machine generations. Grinder components are therefore not universally interchangeable between all TCA, TES, Vero and CTL models.
Before carrying out a repair, it should therefore be established which grinder is actually installed.
A change in the coffee result does not automatically mean that the grinder is worn.
Coffee bean variety, grind setting, contamination, coffee quantity or problems in the brewing unit can also influence the result.
If the grind is too coarse, for example, the water may flow through the coffee puck very quickly. A setting that is too fine, on the other hand, can severely restrict the flow.
Changes to the grind setting should be made while the grinder is running or in accordance with the manufacturer's instructions in order not to place unnecessary stress on the mechanism.
In addition to normal wear, foreign objects can also cause grinder problems.
Small stones or other hard foreign objects can occasionally find their way among the coffee beans despite careful processing.
If such a foreign object reaches the grinder, unusual noises may occur or the mechanism may become blocked.
In this case, the machine should not be restarted repeatedly. A blockage can place additional stress on other grinder components.
The water pump is a central component of the Bosch fluid system.
It transports water from the water tank through the machine and generates the required delivery pressure.
Depending on the programme, the water is then routed through heaters, valves and the brewing unit or to hot-water or milk functions.
A weakening pump may become noticeable through altered delivery performance. However, the pump should not be replaced on suspicion solely because of poor water flow.
If the pump can be heard but only a little or no water flows, there are several possible causes.
These can include air in the system, a water tank that is not correctly inserted, a blocked water path, limescale deposits, a valve problem or a worn pump.
On certain machines, an exhausted or incorrectly installed water filter can also affect the water supply.
During troubleshooting, the water path should therefore be checked step by step to establish how far the water reaches.
The fluid system refers to the complete water path inside the fully automatic coffee machine.
This includes, among other things, the water-tank connection, pump, hoses, pressure lines, distributors, valves, heater, brewing unit and various sealing points.
All these components must work together so that water arrives at the intended location in the correct quantity, at the correct temperature and at the correct time.
Completely different defects can therefore cause similar symptoms.
Within the fluid system, hoses and connectors connect the individual assemblies.
Depending on their position, they have to transport cold water, heated water or steam.
In various plug-in connections, a small O-ring provides the actual seal.
If water leaks from a connection, it should therefore be checked whether the hose itself is damaged or whether only the seal at the connection is worn.
A fully automatic coffee machine must distribute water between different functions. Different valves are used for this purpose.
Depending on the machine, electrical or mechanical valves can open and close different water paths.
A valve fault can therefore present itself in very different ways: water may escape at the wrong point, a programme may receive no water flow or pressure may not be released correctly.
Before replacement, the precise valve function in the respective fault condition should be checked.
One example of a spare part that can be used across several brands is the 4-bar outlet valve 66289.
This valve can be used in various suitable fully automatic coffee machines from Bosch, Siemens, Jura, AEG, Krups, Miele, Melitta and Nivona, among others.
This example in particular shows why the brand designation alone is not always sufficient. Some spare parts are used across several technical machine families.
For repair businesses, we also offer the 4-bar outlet valve as a workshop pack of 25.
In order for coffee to be brewed at the intended temperature, the water must be heated inside the machine.
Depending on the machine generation, different heater or thermoblock designs are used.
However, a temperature problem does not automatically mean that the complete heater is defective.
Temperature sensors, fuses, water flow, limescale or electronic control can also influence the fault.
Because water is heated inside the machine, mineral deposits can form in the fluid system.
The rate at which this happens depends mainly on water hardness, water consumption and filter use.
Limescale can accumulate particularly in heated and narrow water-carrying areas and thereby affect water flow or heat transfer.
For this reason, Bosch fully automatic coffee machines have corresponding descaling or care programmes.
Various Bosch machines use the Calc'nClean care programme.
Cleaning and descaling sequences are carried out according to the machine control.
It is important to distinguish between the care products used: coffee grease and mineral limescale deposits are chemically different types of contamination.
Only products and dosages intended for the respective care programme should therefore be used.
You can find suitable products in our care products section for fully automatic coffee machines.
Regular cleaning and descaling can reduce deposits and contribute to reliable operation of the machine.
However, a mechanically damaged component cannot be repaired in this way.
If, for example, a seal is torn, a hose is damaged, a pump is worn or a valve is defective, the corresponding component must be replaced or repaired.
Care and spare-part repair therefore complement one another, but perform different functions.
Many Bosch fully automatic coffee machines have an integrated or connected milk system for cappuccino, latte macchiato and other milk beverages.
Depending on the model, this includes a milk hose, suction tube, milk nozzle, connecting elements or milk container.
Milk contains fat and protein. Residues can therefore remain particularly in thin lines and nozzles.
The milk system should be rinsed and cleaned regularly in accordance with Bosch's care instructions.
You can find suitable care products in our care category.
If no milk foam or only a small amount of milk foam is produced, there may be different causes.
More common causes include milk residues, a contaminated air hole, a leaking milk hose, incorrect assembly or worn seals.
Only once mechanical and hygiene-related causes have been ruled out should deeper technical faults be investigated.
A systematic diagnosis prevents unnecessary replacement of electronic components.
Water underneath or inside the machine can have many causes.
Possible sources include hose connections, O-rings, valves, the water-tank connection, heater or brewing unit.
Before an assembly is replaced, it should be established as precisely as possible when the water escapes.
If it leaks only during brewing, different components may be involved than with continuous water loss when the machine is already switched off or depressurised.
Water in the drip tray is fundamentally normal. A fully automatic coffee machine deliberately routes water there during rinsing, brewing and pressure-release processes.
It becomes noticeable if the quantity of water increases significantly compared with previous behaviour or hardly any coffee reaches the cup.
In this case, valves, the brewing unit or other components of the internal water path, for example, may play a role.
Here too, it should first be determined during which programme step an unusually large amount of water is being discharged.
If the grinder can be heard operating but little or no coffee is subsequently dispensed, the grinder should not automatically be replaced.
Possible causes can be found, for example, in the brewing unit, water delivery, valves, blockages or coffee outlet.
Coffee grounds that are too fine can also severely restrict the flow of water through the coffee puck.
A diagnosis should therefore take into account the complete process from bean through grinder and brewing unit to the coffee outlet.
A grinder that does not operate does not necessarily have an electrical defect.
On certain machines, very oily beans, for example, may not feed properly into the grinder.
Foreign objects or heavy contamination can also block the bean flow or the grinder.
Only after such causes have been ruled out should it be checked whether the grinder or drive components are technically defective.
If a Bosch brewing unit can no longer be inserted after cleaning, this does not automatically mean that a component is damaged.
The brewing unit or internal drive may not be in the intended basic position.
The assembly should not be forced into the machine. This could damage the locking mechanism, guides or drive.
Instead, the position should be checked in accordance with the operating instructions.
Weak coffee can have different causes.
In addition to the grinder, influencing factors include the grind setting, coffee strength, bean variety, coffee quantity, brewing unit and water flow.
Before grinder components are replaced, it should therefore be checked whether the machine produces enough ground coffee and whether the resulting coffee grounds have a plausible consistency.
A technical repair should always be based on a traceable cause.
Unusual noises can originate from different assemblies.
A pump, for example, sounds different if it draws in air or works against a severely restricted water path.
Cracking or grinding noises, on the other hand, can originate from the grinder, brewing unit or drive.
For diagnosis, it is therefore helpful to observe exactly during which phase of the programme the noise occurs.
Water filters can be used in the water tank of various Bosch fully automatic coffee machines.
A correctly installed filter can influence water quality and limescale load. At the same time, it represents additional resistance in the water path.
If a new filter has not been prepared in accordance with the instructions or there is air in the filter, this can cause water-delivery problems on some machines.
The condition of the filter should therefore also be taken into account if the water flow suddenly changes.
How frequently descaling is required depends on water hardness, consumption, filter use and machine configuration.
Many Bosch fully automatic coffee machines automatically indicate when a care or descaling programme is required.
The programme should be carried out completely in accordance with the respective operating instructions.
Freely chosen household remedies or untested mixtures are not recommended because different metals, plastics and sealing materials are present inside the machine.
You can find further background information in our information on cleaning and descaling fully automatic coffee machines.
An economical repair does not necessarily mean replacing the largest possible assembly.
Depending on the design, a seal, hose, valve or other individual part, for example, may be the actual cause.
If only the defective component is replaced, technically sound parts can continue to be used.
Particularly on older Bosch fully automatic coffee machines, targeted repair can therefore be considerably more economical than completely replacing an assembly or the entire machine.
An older fully automatic coffee machine is not automatically technically obsolete.
Many older Bosch machines have robust mechanical assemblies and can still be repaired even after many years of operation.
Particularly typical wear parts such as seals, pumps, valves or certain components of the water path can still make a repair worthwhile.
The overall condition of the machine and the relationship between repair effort and remaining benefit are always decisive.
Bosch and Siemens fully automatic coffee machines are also widespread in professional repair businesses.
For workshops, it therefore makes sense to keep frequently required wear parts and components used across several brands in suitable quantities.
One example is our set of 25 4-bar outlet valves 66289, which can be used in suitable Bosch and Siemens machines, among others.
You can find further specially assembled bulk and workshop quantities in our bulk discount category.
This point is particularly important with Bosch. Numerous components from different machine generations look very similar at first glance.
Nevertheless, there may be differences in connections, hose diameters, electrical values, sensors, mounting points or software allocation.
A spare part should therefore not be ordered solely on the basis of a product photo.
The combination of E-Nr., existing part number, product description and visual comparison provides a much better basis.
If a part number or Bosch/BSH spare-part number is present on the removed component, this can additionally help with identification.
Manufacturer markings can often be found on pumps, valves, sensors, electronics and heater components in particular.
However, part numbers may have been replaced or superseded by successor numbers over the years.
For this reason too, the complete machine compatibility of the offered spare part should always be taken into account.
When searching online for a Bosch spare part, the Siemens brand frequently appears as well.
This is not necessarily an error. Many machine technologies originate from the same BSH appliance environment and can use identical or similar components.
Accordingly, individual products can be listed simultaneously for Bosch, Siemens and in some cases Neff or Gaggenau.
What matters is not which brand name appears first in the product title, but whether the specific Bosch E-Nr. or machine version is included in the compatibility information.
Not every apparent defect immediately requires a new spare part.
A heavily contaminated brewing unit, for example, can become stiff. Limescale can affect water flow and milk residues can impair a milk hose or nozzle.
For this reason, the maintenance condition of the machine should also be taken into account before replacing parts.
Conversely, even the best cleaning cannot repair a damaged seal, defective pump or broken mechanical component.
You can find suitable care products in our care section for fully automatic coffee machines.
When installing suitable O-rings or at designated sliding points, food-grade silicone grease can be helpful.
It forms a thin lubricating film and makes it easier to insert seals in suitable applications.
Only a small amount should be used. A thick layer of grease provides no additional benefit.
The silicone grease may also only be used at designated sealing and sliding points – not, for example, on grinding surfaces or electrical components.
A fully automatic coffee machine combines mains voltage, water, heat, pressure and moving mechanical components.
Before opening the machine, it must therefore be completely disconnected from the mains supply.
Hot components such as heaters or water-carrying areas should be allowed to cool sufficiently.
Work on mains voltage, the heating system, electronics or safety-relevant components should be carried out exclusively by people with the appropriate specialist knowledge.
If there is any uncertainty, professional repair is the safe solution.
Read the complete model number, including the index after the slash, from the rating plate.
Check whether it is, for example, an older Benvenuto machine, a TES model, VeroCafe, VeroBar, VeroAroma, VeroSelection or a Series 8 built-in fully automatic coffee machine.
Wherever possible, distinguish between problems involving the brewing unit, grinder, pump, fluid system, heater, valves, milk system or electronics.
Compare the design, connections and any manufacturer or part numbers present.
A spare part should only be used if its allocation to the respective machine version can be clearly established.
Depending on the machine generation, available parts include parts for the brewing unit, grinder, pumps and fluid system, seals, valves, hoses and other assemblies.
The most important model identification is the Bosch E-Nr. It is located on the rating plate and should be specified including the digits after the slash.
The index can identify different production versions or machine variants. Individual spare parts can therefore differ even when the basic designation is almost identical.
Technically related or identical components are used in various Bosch and Siemens fully automatic coffee machines. However, this does not apply universally. The specific machine and product compatibility must always be checked.
Certain machines from these brands are based on related technical platforms. As a result, individual pumps, valves or other components can be used across several brands. The actual machine allocation remains decisive.
On many Bosch fully automatic coffee machines, the brewing unit is removable. Bosch provides for regular removal and cleaning of the brew group on corresponding machines. The procedure depends on the respective model.
Possible causes include contamination, dry or stressed sealing and sliding points or mechanical wear. The brewing unit should first be cleaned and inspected in accordance with the operating instructions.
Suitable food-grade silicone grease can be applied thinly at designated sealing and sliding points. Manufacturer specifications and material compatibility must be observed.
In addition to a worn pump, possible causes include air in the system, the water filter, blocked water paths, limescale or a valve problem. The pump should therefore not be replaced on suspicion without further diagnosis.
A certain amount of water is normal due to rinsing and pressure-release processes. If the amount increases significantly, the brewing unit, valves, seals or other components of the fluid system may be involved.
Possible causes range from beans that do not feed properly or are very oily, through a foreign object, to a mechanical or electrical grinder problem.
On various Bosch fully automatic coffee machines, Calc'nClean refers to a guided care programme that combines cleaning and descaling steps. The precise sequence and required care products depend on the model.
This depends on the defect and overall condition. For individual wear parts such as O-rings, pumps, valves or other replaceable components, a repair can still make economic sense even on older machines.
Yes. In addition to normal individual products, we offer larger workshop quantities for suitable components. One example is the set of 25 4-bar outlet valves 66289. Further bulk quantities can be found in the bulk discount section.
You can find our currently available parts directly in the Bosch spare-parts category at NEW-Kaffeevollautomaten.
Bosch fully automatic coffee machines range from older Benvenuto machines through numerous TES and Vero generations to modern VeroCafe and Series 8 built-in machines.
The spare parts required can therefore differ accordingly. For this reason in particular, successful repair begins with clear identification of the machine.
At NEW-Kaffeevollautomaten you will find Bosch fully automatic coffee machine spare parts for different technical areas.
Depending on the machine version, these include components for brewing units, grinders, pumps and fluid systems, seals and O-rings, valves, hoses and further repair areas.
In addition, we offer food-grade silicone grease for suitable O-rings and seals, care and cleaning products as well as bulk quantities for repair businesses and high-volume users.
When identifying spare parts, the following applies particularly to Bosch: read the complete E-Nr., determine the machine generation, narrow down the fault as precisely as possible, compare the existing component and then check the specific compatibility.
All currently available products can be found in our Bosch fully automatic coffee machine spare-parts category.
