Electrolux Washing Machine Error Code E90

The E90 error code on Electrolux washing machines has many interpretations. The error code can appear on the device's screen due to various malfunctions. Users who encounter the E90 error code often don't know what to check first to restore the machine to its previous functionality. We'll discuss how to identify the damage and isolate the problem yourself below.

Transcript from the machine manufacturer

How does the washing machine manufacturer interpret the error? Electrolux issues a code when there is no communication in the control indicator module of the washing machine. In this case, the operating instructions recommend inspecting the connector contacts. They may have become corroded, as the machine is usually located in a bathroom with high humidity. To remedy this, you'll need to clean the contacts and treat them with alcohol.

According to the manufacturer's instructions, an Electrolux washing machine displays the E90 code when the main control board fails. Repairing the module yourself is very difficult, so it's best to contact a professional technician for this problem.

However, based on years of experience, experts say that in most cases, the electronics of the washing machine, as well as the power supply wiring and contacts, are not at fault. Washing machines often display the E90 error code when there's a problem with the drain pump. Less commonly, the cause is a clogged hose or drain pipe, or a debris filter.

Since the E90 code can appear due to various faults, it is necessary to approach the diagnostics of an automatic car with the utmost seriousness.

Intuitive repair

What should you do if the E90 code appears on the display? First, we recommend checking the debris filter and drain hose for blockages. If nothing is found, don't rush to remove the pump from the housing. Try the following:

• remove the top cover of the washing machine by unscrewing the two mounting screws;
• take a hair dryer;
• Dry the control unit and all contacts connected to it thoroughly.

The part must be allowed to dry for a long time. Once the moisture is completely removed from the module, there's a high chance the E90 error will be resolved. If this doesn't help, you'll need to inspect the drain pump. If the pump is fully functional, it's best to contact a service center, where a technician will diagnose the main unit.control module and will repair it.

We remove and check the pump

The drain pump on modern automatic washing machines can be accessed without disassembling the housing. To access the pump, turn off the power to the washing machine, disconnect it from the power supply, drain any remaining water from the drum through the emergency drain pipe, remove the dispenser, and lay the machine on its right side, covering the floor with a rag.

Most Electrolux washing machines have no bottom, so the components located underneath are easily accessible.

This design feature simplifies repairs. However, the lower components can be damaged during handling or transportation, or if exposed to debris and dust.

Some washing machine models have a bottom that acts as a lid. To do this, lay the machine on its side and remove the screws holding the bottom lid in place. Supporting the bottom with a flat-head screwdriver, pry the lid off. This will give you access to the machine's internals.

If your washing machine is equipped with a leak protection system, it includes a tray with a water level sensor, which also needs to be removed. How do you access the pump on these models? You'll need to:

• unplug the washing machine's power cord from the socket and disconnect the water inlet and outlet hoses;
• remove any remaining liquid from the tank using the emergency drain hose or a debris filter;
• move the machine to a place convenient for further work;
• remove the detergent dispenser;
• place the machine gun on its right side, covering the floor with a rag;
• Using a slotted screwdriver, remove the 4 latches holding the tray in place;
• Disconnect the wiring from the sensor attached to the pan, remove the container.

When water enters the tray, the leak sensor sends signals to the control module, which stops the washing machine from operating, preventing flooding. Its contacts should be disconnected.

Once you've located the drain pump, you need to thoroughly inspect it. The main mistake inexperienced mechanics make is rushing to check the pump with a multimeter. In most cases, the problem isn't with the electrical components. The solution to a broken drain pump is often to clean it of any debris, dirt, or hair that has accumulated inside.

The drainage system of automatic washing machines of any brand is designed so that most of the debris entering the machine along with the laundry load ultimately ends up in the drain filter. However, even a small amount of debris caught on the pump impeller is enough to damage the pump.

You can fix the problem by thoroughly cleaning the drain pump. If no debris or dirt is found inside, test the element with a multimeter. If any problems are detected, a new drain pump will need to be installed.

If all DIY repairs have failed and the washing machine still displays the E90 error code, it's advisable to seek professional help. Repairing the system control module on your own is very difficult for the average user.
