Error E90 in an Electrolux washing machine

Error E90 in an Electrolux washing machine Error E90 on Electrolux brand washing machines has quite a lot of interpretations. A fault code may be displayed on the device screen during various breakdowns. Users, faced with the E90, do not know what is best to check first in order to return the machine to its previous performance. We’ll talk further about how to identify damage and localize the fault on your own.

Decoding from the machine manufacturer

How does a washing equipment manufacturer interpret an error? Electrolux issues a code if there is no connection in the control display module of the washing machine. In this case, the operating instructions recommend diagnosing the connector contacts. Perhaps they have oxidized, since the machine is usually in a bathroom with high humidity. To correct the situation, you will have to clean the contacts and treat them with an alcohol composition.

The Electrolux machine issues code E90, according to the manufacturer’s instructions, even if the main control board fails. It is very difficult to repair the module yourself, so with such a problem you should contact professional repairmen. Possible failure of the control module

However, based on many years of practice, experts say that in most cases the electronics of an automatic washing machine are not to blame, as well as the power wiring and contacts. Often the washer displays fault code E90 when there is a problem with the drain pump. Less commonly, the cause of the error is a clogged hose or drain pipe, or a garbage filter.

Since the E90 code can appear due to faults that are not similar to each other, diagnosing an automatic machine must be taken as seriously as possible.

Intuitive repair

What should I do if the display shows code E90? First of all, it is recommended to check the garbage filter and drain hose for blockages. If nothing is found, do not rush to remove the pump from the housing. Try the following:

remove the top cover of the washing machine by unscrewing the two fastening screws;
take a hairdryer;
Dry the command device and all contacts connected to it thoroughly.

It takes a long time to dry the part. After completely removing moisture from the module, there is a high probability of eliminating error E90. If this measure does not help, you will have to inspect the drain pump. If the pump is in full working order, it is better to contact a service center, where a technician will diagnose the main control module and will repair it.

Removing and checking the pump

You can get to the drain pump on modern automatic machines without disassembling the housing. To gain access to the pump, you should turn off the power to the washing machine, disconnect the equipment from the communication networks, remove the remaining water from the tank through the emergency drain pipe, remove the dispenser and place the machine on the right wall, having previously covered the floor with a rag.

Most Electrolux brand washing machines do not have a bottom, so the elements located below are freely accessible.

This design feature simplifies repairs. On the other hand, the lower components may be damaged when carrying or transporting the equipment, or if they are exposed to debris and dust.

Some models of washing machines have a bottom, which is presented in the form of a lid.In this situation, it is also necessary to lay the equipment on its side and unscrew the bolts holding the bottom cover. Support the bottom with a flat-head screwdriver and pull off the lid. This will open access to the “insides” of the machine. remove and check the pump

When an automatic machine is equipped with a protective system against emergency leaks, its design includes a tray with a water level sensor, which also must be removed. What should I do to gain access to the pump on such models? Have to:

unplug the power cord of the washing machine from the outlet, disconnect the water supply and drainage hose;
remove remaining liquid from the tank using an emergency drain hose or a garbage filter;
move the machine to a place convenient for further work;
remove the detergent dispenser;
put the machine gun on its right side, covering the floor with a rag;
using a slotted screwdriver, pull off the 4 latches holding the tray;
Disconnect the wiring from the sensor attached to the pan and remove the container.

When water gets into the pan, the leak sensor sends signals to the control module, which pauses the operation of the washing machine, preventing flooding; it is its contacts that should be disconnected.

Having found the drain pump, you need to carefully inspect it. The main mistake of inexperienced craftsmen is the desire to immediately check the pump with a multimeter. In most cases, the problem is not the electrical part. The solution to the problem of a broken drain pump is often to clean it of debris, dirt, and hair accumulated inside.

The drainage system of automatic machines of any brand is designed in such a way that the majority of the debris that gets inside along with the items loaded for washing ultimately settles in the drain filter.However, even a small part of debris that gets on the pump impeller is enough to damage the pump.

The situation can be corrected by thoroughly cleaning the drain pump. If no particles of debris or dirt are found inside, test the element with a multimeter. If problems are found, a new drain pump must be installed.

If all attempts that you can do yourself are completed, and the washing machine still displays fault code E90, it is advisable to seek help from specialists. It is very difficult for an ordinary user to repair the system control module independently.
