Error E90 in the Electrolux washing machine

Quite a lot of interpretations have the error E90 on washing machines of the Electrolux brand. The fault code can be displayed on the device screen in case of various breakdowns. Users faced with the E90 do not know that it is better to check first of all in order to return the machine to its previous performance. How to identify the damage and localize the malfunction on our own, we will talk further.

Decryption from the manufacturer of cars

How does the manufacturer of washing equipment interpret the mistake? Electrolux issues a code in the absence of communication in the control display module of the washer. In the operating instructions in this case, it is recommended to diagnose the contacts of the connectors. Perhaps they have oxidized, since the machine usually stands in a bathroom with high humidity. To rectify the situation, it is necessary to clean the contacts and treat them with an alcohol compound.

The machine Electrolux gives the code E90, according to the instructions from the manufacturer, and in case of failure of the main control board. It is very difficult to repair the module yourself, therefore it is worth contacting professional masters with such a problem.

However, based on many years of practice, experts argue that the electronics of a washing machine in most cases have nothing to do with it, just like power wiring and contacts. Often, the washer shows DTC E90 when there is a problem with the drain pump. Less commonly, a clogged hose or drain pipe or a waste filter becomes the cause of the error.

Since the E90 code may appear in case of malfunctions that are not alike, it is necessary to approach the diagnosis of the automatic machine as seriously as possible.

Intuitive Repair

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

• remove the top cover of the washer by unscrewing the two fixing screws;
• take a hairdryer;
• Dry the control unit and all contacts connected to it well.

It takes a long time to dry the part. After the complete removal of moisture from the module, it is highly likely to eliminate the error E90. If this measure does not help, you will have to inspect the drain pump. If the pump is fully operational, it is better to contact the service center, where the wizard will diagnose the maincontrol module and repair it.

We remove and check the pump

You can get to the drain pump on modern automatic machines without disassembling the housing. To gain access to the pump, disconnect 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 lay the machine on the right wall, after covering the floor with a rag.

Most washing machines of the Electrolux brand have no bottom, so the elements located below are in the public domain.

This design feature simplifies repair. On the other hand, lower components can be damaged when carrying or transporting equipment, or if debris and dust get on them.

Some models of washers have a bottom, which is presented in the form of a cover. In this situation, it is also necessary to lay the equipment on its side and unscrew the bolts holding the bottom cover. While supporting the bottom with a flat screwdriver, the cover should be removed. This will open access to the "insides" of the machine.

When the machine is equipped with a protective system against emergency leaks, in its design there is a pallet with a water level sensor, which must also be removed. What to do to access the pump on such models? Have to:

• Unplug the power cord from the power outlet, disconnect the set hose and drain the water;
• remove fluid residues from the tank using the emergency drain hose or trash filter;
• move the machine to a place convenient for further work;
• remove the detergent dispenser;
• put the machine on the right side, covering the floor with a rag;
• using a slotted screwdriver, unscrew the 4 latches holding the pan;
• disconnect the wiring from the sensor attached to the pallet, remove the container.

The leakage sensor, when water enters the pan, sends signals to the control module, which suspends 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 masters is the desire to immediately check the pump with a multimeter. In most cases, it's not about the electrical part. The solution to the problem of a breakdown of the drain pump is often to clean it of debris, dirt, hair that has accumulated inside.

The drainage system of automatic machines of any brands is designed in such a way that the largest part of the garbage falling inside along with things loaded for washing settles in the drain filter. However, even a small part of the litter that has fallen on the impeller of the pump is enough to disable the pump.

You can correct the situation by carefully cleaning the drain pump. If particles of debris and dirt are not found inside, test the element with a multimeter. In the event of a malfunction, a new drain pump must be installed.

If all the attempts that you can make with your own hands are completed, and the washing machine still shows the DTC E90, it is advisable to seek help from specialists. It is very difficult for an ordinary user to repair a module controlling a system by themselves.
