If the Bosch dishwasher gives an error E18, you need to know its decoding. Briefly: too much water. The full value is indicated in the instruction manual.
Like any appliance, dishwashers are prone to breakage. Control modules on modern models can carry out diagnostics themselves. As soon as a malfunction occurs, a malfunction code is displayed. Below you will learn how to fix everything yourself.
Why PMM "Bosch" gives an error
A dishwasher can show an E18 value for several reasons:
- System crash.
- Increased water level in the tank.
What to do in this case? Try resetting the screen icons by rebooting:
- Unplug the appliance.
- Wait 10-14 minutes.
- Repeat start.
If the error code does not disappear, wait until the dishwasher finishes the program and completely drains the water from the hopper. If after that the symbols still light up, you need to look for the causes of the breakdown.
One of them - level sensor malfunction. This part monitors the water level in the tank and transmits the readings to the control board. The pressure switch is probably broken or gives inaccurate information.
How to fix the problem? Only replacing the sensor will help.
In severe cases the reason may be in the control board. To diagnose and replace it, it is better to call the wizard. But if you want to inspect it yourself, do this:
- Disconnect the PMM from the network.
- Open the door.
- Remove the bolts from the inside.
- Close the door and equip the control panel.
- Behind it is a module that must be disconnected from the wiring.
Noticed burnt areas? Take the part for repair.
Follow the rules of operation of the equipment, then it will not need to be repaired for a long time. In addition to the correct installation of the PMM, it is important:
- carry out cleaning and remove blockages after washing;
- observe the rules for loading dishes and detergents.
