Everyone is trying to choose a reliable technique that will last longer without breakdowns. Unfortunately, even the dishwashers of the German company Bomann are prone to problems. Bomann dishwasher errors help to understand the cause of the malfunction. But the fact is that the PMM of this brand has only three types of codes that do not fully reflect possible problems. How to restore the equipment?
How are Behmann DTCs decoded?
Thanks to the electronic control of the dishwasher, the Bomann have a self-diagnosis function. Therefore, in the event of a malfunction, the technician stops work and displays error codes on the screen. Additionally, indicators indicate a breakdown. What does the appearance of characters on the display mean:
- E1 (quick wash lamp flashes on the screen). The meaning of the code is: there were problems with the water supply to the hopper. Perhaps they turned off the water, a hose or filter clogged. A serious problem could be the breakdown of the filler valve or pressure switch.
- E4 (the economical washing signal flashes). The PMM bunker is full of water, leakage is likely. What does it mean? Drainage of the dishwasher, sewage system, impeller of the pump could become clogged. Damage to the pump, control module is also possible. When leaking, check all connections and seals.
- E8 means that the control valves are faulty. Contact the service center.
How to fix the problem with your own hands? Do not rush to immediately disassemble the machine, start by rebooting. In electronic control, a failure also occurs, which leads to the issuance of a code on the screen. In such situations, a reboot will help. Here's how to restart the PMM:
- Unplug the dishwasher.
- Wait 10-15 minutes.
- Connect the equipment to the network.
If after this the error no longer appears on the scoreboard, then there is nothing to worry about. If the problem recurs, then decisive action is worth taking.
Repair Dishwasher Bomann
In addition to the above problems, the Bomann dishwasher is subject to other breakdowns. Eliminating them is not so simple, but there are times when the problem lurks in improper operation. It is enough to change one point in the usual use of the dishwasher, and the equipment will work like a clock. That is why the PMM is accompanied by instructions that must be followed.
Causes of Breakdowns of the Behmann Dishwasher
What should I do if the machine stops working and there is no trouble code on the display? We'll have to look for the cause on our own, and we will show you how to fix it.
Here are the most common breakdowns:
- The dishwasher does not turn on. The reason may be a power outage, a violation of the integrity of the wires, plugs or sockets. A serious problem is the breakdown of the control module. Most often, it suffers from moisture or power surges.
- Water heating does not work. Why is this happening? The thing is the malfunction of the heating element (TENA). Water, which contains salts, passes through a flow heater daily. Being deposited on the heating element, they form a layer of scale, which leads to overheating and combustion of the part. The temperature sensor may also break.

- Incorrect installation and connection of the PMM leads to various malfunctions. This includes the lack of drainage of water, leakage, poor fit of the door to the body.
Let us consider in more detail each of the failures, as well as options for their elimination. Remember that if your car is under warranty, do not open it yourself. It is better to contact the master.
The dishwasher does not start
What to do in this case? First check:
- The presence of electricity in the room.
- Serviceability of the plug, socket, integrity of the cord.
- Does the power button go down?
The mechanical or touch button should be checked for correct contacts. If they are burnt, then it is enough to strip the wires to restore work. Otherwise, you will have to completely change the part.
To verify problems with the control module, you need professional diagnostics. But you can inspect the element for damage and burns yourself. How to proceed:
- Disconnect the equipment from the network.
- Open the door and loosen the screws on the inside perimeter.
- Unscrew the upper bolts completely, remove the control panel.
Panel disconnect
- From the panel to the sensor is a black wire that needs to be disconnected.
- Now unscrew the screws holding the module, and also disconnect the wiring.
Wires that need to be disconnected
You can inspect the module. Noticed burnt areas? Give the module to a service center for repair or call the wizard. This method will help especially incredulous users who want to make sure that the element is broken.

Water is not poured into the PMM
If the E1 fault code is displayed on the screen or you notice that there is no water inlet, then make sure that:
- There is water in the tap. Otherwise, you will have to wait for its submission.
- The shut-off valve is open at full power. Perhaps it was accidentally blocked.
- The water supply hose is in the normal position (not twisted).
Everything is good? Then move on to decisive action. Start by checking the system for clogging.
- Disconnect the hose from the body. If it is connected through the inlet valve, then pull out the filter screen.
How to remove the filter
- Rinse parts under pressure.
There is a lot of water in the PMM tank
A trouble code reports the problem, or a water overflow becomes apparent. First of all, it is necessary to clean the drainage system, which is often clogged with garbage, the remnants of food and napkins, fragments of dishes are not excluded. How to fix the problem yourself:
- Open the door of the PMM and pull out the baskets.
- Take out the filter, as well as the metal mesh behind it.
- Rinse parts with running water.
- Remove water from the opening behind the filter with a sponge.
- Inside you will see a plastic pump cover. Pull it to the side, then towards yourself and remove.
That's how the cover is dismantled
- Clean the impeller from foreign objects. Be sure to use gloves, the impeller is often blocked by broken glass or bone.
Next, inspect the drain hose. Is it located and connected normally? If the drain is high, then the pump may not be able to handle the load. If everything is normal with the hose and it is not clogged, go to the PMM pump. There is an element in the assembly with a flowing heater. To replace it, you will have to disassemble the car a little:
- Turn the dishwasher on its side.
- Remove the bottom cover, which can be fastened with latches.
- Disconnect the wires from the pump.
- Unclench a hose collar, remove it from a place.
Metal clamp
- Turn the pump counterclockwise.
PMM pump
- Install the new part and reconnect in the reverse order.
The video instruction will help you:
If a leak is noticed, then carefully inspect the housing. Leaking back? Check the attachment of the drain hose. Flowing Ahead? Make sure that the door fits snugly against the body and that the seal is not deformed. Tighten all available clamps and joints.
TEN does not warm
Why does the heater fail? Mainly due to the low quality of tap water, as a result of which a scale layer forms on the surface of the parts. The thicker the layer, the lower the thermal conductivity. Therefore, the element overheats and burns.
Another reason is the power surges. It is not in vain that when connecting large equipment, it is recommended to install a voltage stabilizer. To replace the heater, do this:
- Disconnect the heater from all communications.
- Remove the baskets from the hopper, pull out the sprayer by pulling it towards you.
Sprayer in the pan
- Remove the filter from the pan and the screen behind it.
- Remove the screws that secure the heating block.
- Turn the PMM on its side, remove the bottom. There you will see an assembly consisting of a pump, a heater and nozzles.
- Disconnect the wiring from the heater, rotate and remove the pump.
Heater wiring
- Disconnect all pipes and hoses.
- Remove the old heater and install the new one in the reverse order.
Photograph the location of the wires so that after dismantling, connect the chips correctly.
Select a new item with the same number as the previous one. You can even go with the old heater to the store, so as not to miscalculate.
To avoid problems with improper installation and connection, contact specialists for help. So you keep the guarantee and get rid of unnecessary problems. Here are the basic rules that every user must adhere to:
- To clear dishes from the remains of food before loading.
- Position the instruments in the hopper so as not to interfere with the rotation of the nozzles.
- Correctly select the washing program according to the type of dishes.
- Regularly replenish salt in the tank. The tool not only protects PMM parts from scale, but also allows you to get clean devices without streaks.
- Wipe the seals and leave the door open briefly after each wash.
- Clean the drain filter at least once a week.
Follow basic guidelines and avoid the typical problems users face. For replacement, select only original accessories, then the dishwasher will last for more than one year.
