What do Kuppersbusch dishwasher errors mean? The code appears as a result of a breakdown of the PMM nodes or a malfunction. Therefore, in the instructions, the manufacturer indicates the decoding of each symbol of this brand. If your manual is lost, then the value can be found in the article. You will also learn how to fix problems and restore the operation of equipment.
How are the Kuppersbush fault codes deciphered?
The dishwasher, although an assistant in the kitchen, also needs separate care. Errors in operation, an abundance of food and fat residues, power surges in the network – all this contributes to the blocking of work or even the breakdown of individual nodes. When a breakdown code appears on the display, a reboot will help. If the cause is a system failure, then the characters will disappear from the screen.
How to restart PMM:
- Unplug the machine.
- Wait 10-15 minutes.
- Connect the plug to the socket.
Fault code appears on display
If the codes reappear on the display, then find out their meaning:
- EF1, E22 (end flashes twice). Drain does not work, water remains in the hopper after the end of the cycle. It is worth checking the drain hose, filter and pump impeller. A broken pump needs to be replaced.
- EF2 (the end lamp lights up three times). There is an excess of foam in the tank, probably a leak has occurred. It is necessary to eliminate the cause of the leak.
- E11 (end or start blinks once). Problems with water supply. Check water supply and hose condition. Clean intake filters.
- E12. Failures with water intake during the drying mode. Contact the service center.
- E22. No drain when dryer starts. Clean the debris filter system.
- E31, E32. The liquid does not reach the set level. The reason is incorrect operation or breakdown of the level sensor.
- E33. There was a malfunction in the operation of the heater, or voltage fluctuations in the network affect.
- The appearance of codes E41, E42, E43, E44, E45 means that the door does not fit snugly against the PMM body or the lock is broken.
- E51, E53. The electronic module has failed.
- E52. Communication with the tachometer has been lost. The reason is damage to the wiring or breakage of the sensor.
- E54. Broken relay on the electronic board. It’s a matter of voltage fluctuations in the network or moisture ingress.
- E61, E62, E66. Slow heating of water, problems in the operation of the heating element or temperature sensor.
- E71. Washing thermistor is defective.
- E72, E73. Problems with the operation of the thermistor drying.
- E91. Lost communication between main module and display board.
Now you know what each error code means. You can start repairing the malfunction, and our recommendations will help to cope with this. Below we list additional breakdowns that are typical for Kuppersbusch equipment.
Causes of breakdowns of the Cuppersbush dishwasher
Often, equipment fails due to external factors and due to wear of components. Here’s what contributes to premature failure:
- Improper installation and connection of communications.
- Lack of timely service.
- Violation of operating rules.
As a result, malfunctions appear, which are indicated by the following symptoms:
- PMM does not turn on. The problem is with the plug or socket. The power cord may be damaged. The door lock could also fail, which is why the latter does not fit well to the body. It is worth checking the serviceability of the start button, surge protector, control module.
Noise filter
- Dishwasher does not heat water. The point is a malfunction of the heating element or thermoelement. The reason may also be in the wiring or relay of the electronic board.
- The machine does not take water into the tank. Probably, the water was turned off, the inlet valve was closed, the dishwasher door was not fixed. The inlet filter could also become clogged or the valve could fail.
That is why there are breakdowns in the PMM Kuppersbusch. How to fix the situation with your own hands? This will help step-by-step instructions for replacing nodes. You will also learn how to avoid operating errors that lead to malfunctions.
Dishwasher does not heat water
Among the obvious breakdowns of the heating element, temperature sensor or relay on the control module, there are also non-obvious problems. For example:
- Incorrect connection of the machine to the water supply.
- Severe blockage of the drain filter.
- Lack of prevention of scale formation.
Successful operation starts with the right connection. General recommendations call for installing a drain hose at a height of up to 60 cm. In fact, it all depends on the type of model – desktop or floor. Therefore, it is better to refer to the instructions. How does the connection affect the heating of water? With a low location of the hose, the water goes into the self-drain, not having time to warm up normally. Therefore, first of all, check this moment.
Machine Wiring Diagram
Look into the hopper while washing. If water accumulates in the pan, then it’s time to clean the trash filter. Blockage interferes with normal circulation and heating of the liquid, therefore:
- Open the door.
- Take out the baskets.
- Pull the filter out of the pan.
- Remove leftover food, rinse under the tap.
Debris filter in the hopper tray
At least once every six months, it is necessary to run an idle cycle at a high temperature with the addition of anti-scale agents. Hard water, when heated, releases potassium and magnesium salts, which are deposited on the details of the PMM. As a result, the layer prevents the heater from giving off heat, the element overheats and burns out. At home, baking soda and vinegar will help get rid of plaque.
How to repair a malfunction with your own hands? If the heating element burned out, do this:
- Disconnect the PMM from the mains and water supply.
- Turn the body sideways.
- Remove the bottom panel.
- The heater is connected to the pump.
- Disconnect wiring from parts.
Disconnecting wiring
- Loosen the clamps and disconnect the hoses.
- Turn the pump counterclockwise.
- Take out the heating element.
Install the new element in reverse order. Before turning off the chips, take a picture of their location.
PMM won’t turn on
Why does the machine not work after connecting to the network? Inspect the power cord for damage. Sometimes during installation, users accidentally put the case on the cord, so the PMM does not start. The same applies to plugs and sockets.
One of the causes of the problem is the burnout of the network filter. The fuse protects the electronics of the equipment from burning during power surges in the network. It’s easy to look at it. The part is located at the place where the wire is connected to the PMM body. If the filter is swollen or burnt, replace it.
Fuse in the dishwasher
Examine the control panel and power button. Sometimes, due to the ingress of detergents, the button sticks. How to fix the situation? Disconnect the panel, clean the contacts and the button seat. Let’s describe how to disassemble the door:
- To remove the panel at the top of the door, unscrew the bolts around the inner perimeter.
- Split two panels.
- Remove the module by disconnecting the wiring.
Dismantling the panel
Now you can inspect the buttons and their contacts.
Manufacturers recommend installing a voltage stabilizer that levels out drops in the network.
The door does not fit snugly against the body
The dishwasher mechanism works in such a way that water begins to be poured into the tank only after the electronic lock is locked. You hear its operation as a click during closing. What to do to restore the operation of equipment? Lock needs to be replaced:
- Open the door, unscrew the bolts around the perimeter.
- Remove the front panel.
- Disconnect the lock wiring.
- Unscrew the fasteners of the device.
- Remove the non-working device, install a new part and connect in reverse order.
What does the blocker look like?
A video on the topic will help you understand the sequence of work using an example:
Water does not enter the bunker
So, the program is running, the dishes are loaded. That’s just the sound of water intake is not audible, after which the PMM displays an error code on the display. What does it mean? Check this:
- Is there water in the room or maybe it was temporarily turned off.
- Is the inlet valve open?
- Is the hose positioned properly? It must not be pinched or twisted.
Press the door tighter, make sure that the dishes do not interfere with normal closing. Next, clean the intake filter and check the valve. The mesh is installed between the hose and the machine inlet, creating a barrier to debris and rust. Next is the valve. Its membrane opens, letting in the flow, and then closes.
How to get to the details yourself:
- Shut off the valve.
- Disconnect the hose from the housing.
- Remove the mesh and rinse under pressure.
Remove stubborn dirt with a brush
- Next, disconnect the wires from the valve, unscrew the bolts.
- Replace if defective. The element cannot be repaired.
To confirm the breakdown of the part, watch the video:
Liquid does not drain
If there is liquid left in the pan after the end of the wash cycle, clean the drain filter as described above. Did not help? Check drain hose and siphon for blockage. After that, inspect the pump and replace if necessary. Dismantling the pump is described in the section on replacing the heating element. To extend the life of the pump, proceed as follows:
- Thoroughly clean dishes from food debris. Bones and fragments of dishes can deform the impeller or get into the snail.
- Connect drain correctly. A large distance between the housing and the outlet, as well as a high position of the hose, leads to rapid wear of the assembly.
These are typical breakdowns for Kuppersbusch dishwashers. The instruction will help to understand the features of connection and use of equipment. When disassembling the PMM, pay attention to the individual characteristics of the machine.
