Methods for resolving the error
Before you begin to resolve the error E20, first of all de-energize the washing machine Electrolux . After performing the above manipulation, unscrew the drain hose and drain all the water through it. Now you need to get all the clothes out of the drum, and going through the list above, start searching for errors.
If during the time you released water, it flowed out without any delays, then you could simply clog the siphon or the riser, or the pump could clog up.
After checking the sewer system, proceed to check the drain pump and filter mesh. Gently unwind the part and dismantle it from the case of the washing machine, then thoroughly clean it with a needle, then rinse under running water. In order to get to the pump Electrolux washing machine you have to dismantle the back panel. To do this, you must do the following manipulations:
- Turn off the four screws that secure the back cover.
- Remove the back cover.

- Phillips screwdriver;
In order to clean the pump, unscrew the cap and check the impeller. Hair and woolen threads from things could settle on it. Carefully clean everything from rubbish and rub it dry. With the help of a multimeter, we check the pump for performance. To do this, apply the probes to the pump and on the screen of the device monitor the resistance. The working device should produce a result in the region of 200 ohms, in case of non-compliance with this value, replace the pump with a similar new unit.
In order to easily assemble the car in the future and return all the parts in place, we recommend you to shoot or photograph the process.
After replacing the pump, we start the washing machine in test mode, and follow its operation. If, after replacing the pump, the error has nowhere to go, check the operation of the pressure switch and the wiring that connects the water level sensor with the pump and the electrical board. In most cases, the error is due to damage to the wires, and not the pressure switch itself. Error codes of the pressure switch are displayed on the display as: E11 and E32.
In the event that the test of the pressure switch and wires, did not give any result, and the error still adorns the display, check the electronic module. This is a rather expensive and painstaking pleasure, not all masters are ready to take on this problem. However, do not be upset, this error is displayed quite rarely.
