EFO error in Electrolux washing machine


All Electrolux washing machine models are equipped with a self-diagnosis function.
In the event of a malfunction, signals appear on the control panel. Information error code (if the control panel of the household appliance is equipped with a special display) or blinking in a certain sequence of light indicators.

Understanding the malfunction signals will help you quickly determine the cause of the breakdown and decide whether it is worth carrying out the repair yourself or whether it is more advisable to use the services of a service center technician.

Fault signals for Electrolux washing machines without display

An Electrolux washing machine without a display on the control panel signals a malfunction by flashing indicators. Depending on the type of control module (EWM 1000 or EWM 2000), the combination of code flashes and the method of decoding them differs.

In a washing machine with an EWM 1000 control module (you can check the type of module in the passport of the household appliance), the error code can be deciphered by the blinking of two LED lights located near the “Start/Pause” and “End of washing” buttons (pictured item 2).

The number of flashes of the first LED is the first digit of the error code . The second digit of the code is determined by the number of flashes of the second indicator.

For example: the first indicator blinked three times, after two seconds the second indicator blinked five times. This combination of blinking indicators indicates error E35.

In a washing machine with an EWM 2000 control module, eight LED lights (located vertically on the right side of the panel) are used to decipher the breakdown signal. The four upper lights are responsible for the first digit of the error code, the four lower LEDs are responsible for the second digit of the code (in the photo, item 3, item 4). The LED light counting starts from bottom to top .

Using the table, let's look at the example of decoding error code E53. In the bottom row of four indicators, the first and third lights light up, in the top row of four indicators, the first and second lights light up.

How to recognize the code on an Electrolux washing machine without a display

On simple models of Electrolux washing machines there is no display, but they also have a diagnostic system. They notify the user of an error by blinking LEDs. There are many control panels for such machines, but the control module used is of primary importance.

On Electrolux washing machines with an EWM 1000 control module, two LEDs indicate the error code. The first refers to the “Start” button, and the second is an indicator signaling the end of the wash. These LEDs blink, then stop briefly and blink again in a preset sequence. The number of blinks of the first LED indicates the starting digit of the error code, the second LED – the last digit. For example, if the initial LED blinked five times and the last LED blinked once, the error code is 51.

Electrolux washing machines with an EWM 2000 control module have a more difficult to understand error code pattern. To read the fault message, you need to look at the right side of the control panel. There are eight indicators there. The four LEDs on top indicate the first digit of the fault code, the four LEDs on the bottom indicate the second digit.

To calculate the error code, you need to look at the table.
LED number in group

Number
012345678910, A11, B12, C13, D14, E15, F
4XXXXXXXX
3XXXXXXXX
2XXXXXXXX
1XXXXXXXX

LED numbers are calculated starting from the bottom. For example, if the first LED and the fourth are lit in the top row, then the initial digit in the fault code is 9. Now you should pay attention to the second row. If only the first LED is lit, the second digit of the code is 1. Thus, the fault code is E91.

How to reset?

In order to reset the error code in a washing machine with a program selector, you must simultaneously hold down the buttons as shown in the figure :

For washing machines without a selector, the error is reset by simultaneously pressing buttons 2,4 (see figure):

  • Short circuit of the control triac;
  • Malfunction of the tachogenerator and adjacent parts;
  • Failure of the reverse drive motor;
  • Malfunction of the electronic controller;
  • Bearing wear.

Sometimes a few worn-out parts are very easy to replace, but sometimes serious repairs are required. In any case, every technician at our service center can easily handle any type of problem. Only professionals work for us.

Repairing a washing machine is a rather complex process that requires certain knowledge and skills. Despite the fact that the built-in self-diagnosis system through an error code helps you independently determine the cause of the malfunction without understanding the internal structure, it is better to entrust the repair of the washing machine to professionals.

You can call a specialist to your home by phone. Contacts of service centers or individuals involved in the repair of washing machines can be easily found through Internet search engines.

When submitting an application you must provide:

  • washing machine model,
  • year of its release,
  • error code.

After a visual inspection and more detailed diagnostics, the technician will be able to tell you how much it will cost to repair a household appliance.

Under no circumstances should you pay in full for a master's work that has not yet been completed . Otherwise, there is a high risk that the “repair” will not be completed completely.

Depending on what led to the appearance of the error code, restoring the functionality of the Electrolux washing machine will cost from 1,500 rubles. up to 3500 rub.

WHAT TO DO IF THE DISPLAY OF THE ELECTROLUX WASHING MACHINE SHITS ERROR CODE E50?

The E50 code encrypts a whole range of errors. The first step is to find out exactly what kind of problem happened with the equipment. And to do this you need to press the “start” button and the button located next to “start”. Hold these buttons until the display shows another combination. You must remember the new number and then inform the master.

Is it possible to correct the situation on my own without resorting to the help of specialists? This is what you need to try first:

  • Pressing the “start” button and the adjacent button sometimes helps to correct the situation and return the unit to operation. Helps if this code is just a system failure.
  • Try turning the machine on and off again. This will help, again, if the equipment is simply malfunctioning.
  • Sometimes the problem is the machine’s inability to drain water, the main reason for which is a blockage. You need to disconnect the drain hose and check. We remove the blockage by hand, attach the hose back, and the machine washes again.

These steps don't help? So, it's time to call a specialist.

Other items

The collector lamellas are responsible for transmitting electric current to the rotor. Lamels are copper or alloy contacts that are attached directly to the shaft. They can peel off and be destroyed when the motor is jammed (or due to interturn short circuits in the windings). Damaged contacts have burrs and detachments.

Important! If the damage is minor, you can fix the problem with sandpaper and a lathe.

Starting and acceleration of the engine is also disrupted if the winding is damaged. A short circuit occurs and the electric motor overheats. The temperature sensor detects the high temperature and goes into emergency mode, turning off the system. This vicious circle can only be reset or interrupted by troubleshooting, otherwise it will repeat again and again until the thermistor fails. The quality of the winding is checked with a multimeter:

  • turn on the “Resistance” mode on the device;
  • the probes are applied to the lamella contacts;
  • The normal resistance value is 20-200 Ohms, if more is displayed on the display, then the problem is an open circuit, less - a short circuit.

A multimeter is also used to diagnose the stator. For this purpose, turn on the buzzer mode and apply the probes one by one to the winding. If the tester does not respond, everything is fine. If damage is detected, do not rush to repair the electric motor yourself. It's too expensive, it's much easier to buy a new engine.

The triac controlling the UBL burnt out

The second possible reason for error E41 is a burnt triac or faulty control board. That is, the UBL works normally, but the system does not receive a signal that a blockage has occurred. To repair a damaged module, the circuit will have to be removed and inspected . To do this you need:

  • remove the detergent dispenser by rocking the tray and forcefully pulling it towards you;
  • find 2 bolts in the hole next to the cuvette compartment and unscrew them;
  • remove 4 more screws located at the end of the panel under the top cover of the machine;
  • take the panel with your hands and gently move it up;
  • use a flat screwdriver to pry off the latches;
  • disassemble the panel housing and remove the control board.

When removing the control board from the Electrolux washing machine, you should secure all the disconnected wires to the camera so as not to mix up the connections during reassembly.

As soon as the board is in your hands, you should carefully inspect its surface for defects, traces of burning or mechanical damage. If there are no visible reasons for concern, you will have to again resort to using a multimeter and check each triac for breakdown. The following instructions will help you understand what to do to check the module.

  1. We switch the tester to audio dialing mode.
  2. We touch contacts A1 and A2 with the probes and look at the screen. When “1” or “OL” is displayed, the triac is working, and when the number is close to zero, it is necessary to correct the situation by replacing the part.
  3. When there is no TZ between the terminals, we check the control electrode. We direct the ends of the device to the power terminals and the main electrode. At values ​​of 80-200 there is nothing to worry about.
  4. We close the main electrode, and after a couple of seconds we remove the current, observing the state of the triac. If the switch does not close, then a full repair with replacement is required.

But it’s better not to experiment with the board and entrust the solution to the problem with error E41 to the service center technicians. Remember that the module is a fragile and expensive thing, so without experience and practice it is easy to aggravate the breakdown.
