What does error E40 mean on an Electrolux washing machine and how to fix it?

It would seem that everything is as usual: the laundry is loaded, the powder is poured in, the door is closed, but at the stage of starting the wash, something went wrong.

The hatch door was not blocked and, as a result, the washing machine did not start the selected washing mode. Instead, error E40 appeared on the control panel.

Information about what exactly can provoke such a situation will help restore the working condition of the Electrolux washing machine as quickly as possible.

What does error E40 mean on an Electrolux washing machine and how to fix it, we will tell you further.

What is this code that the Electrolux washing machine produces?

The Electrolux washing machine signals problems with the hatch locking with error E40. There are many reasons why the seal of the hatch closure is broken.. Deciphering the E40 information code helps to more accurately determine what exactly caused the malfunction.

To enter the diagnostic mode of the Electrolux washing machine without a software selector (the washing mode is selected by pressing individual buttons), you must simultaneously press and hold two buttons in the right corner of the control panel (pictured item 1) and one large round button located on the right sides (pictured item 2).

As soon as all the indicators flash simultaneously (a signal that the login to the diagnostic system was successful), a code will appear on the display that pinpoints the cause of the malfunction washing machine:

• E41 - the hatch door is not tightly closed;
• E41 - the hatch locking device has failed;
• E43 - the triac responsible for the operation of the UBL has failed (additional diagnostics of the control module is required);
• E44 - the hatch door opening sensor is faulty;
• E45 - break in the eclectic circuit between the triac and UBL.

For models of washing machines with a program selector (the washing mode is selected by turning the knob of a special switch), to enter the diagnostic system, you must press and hold the two outermost buttons on the right side of the control panel (item 2 in the photo).

In Electrolux washing machines without a display, problems associated with locking the hatch door are indicated by flashing indicators.

In models with an EWM 1000 control module, the code is transmitted by two indicators: one is located near the “Start/Pause” button, the second is located near the “End washing” button. The indicators flash in turn, with a short pause. The number of flashes determines the two-digit value of the fault code. In the specific case of error E40, the indicators flash once four times.

For washing machine models with an EWM 2000 control module, error code recognition is carried out in a slightly different way. To obtain the necessary information, count the number of blinks of the eight indicators located on the right side of the control panel. The number of blinks of the four upper indicators is the first digit of the error code, the number of blinks of the second four indicators is the second digit of the code.

For a specific error E40, only the third indicator out of the top four blinks four times. The serial numbers of indicators are determined from bottom to top.

Why does it appear and what to do?

The process of eliminating error E40 of the Electrolux washing machine is carried out according to a clearly defined algorithm, starting with the simplest actions, gradually moving towards more complex repairs that require certain knowledge and training.

Checking the tightness of the hatch door

The first thing you need to do when the washing machine signals a malfunction with error E40 is open the door, check the rubber seal of the hatch for stuck debris, close the hatch door again (press until it clicks).

Testing and changing the hatch locking device (UBL)

The absence of a characteristic click when closing the hatch doors is a signal that the possible cause of the E40 error lies in a malfunction of the hatch locking device (UBL).

Algorithm of actions:

1. Open the hatch of the washing machine.
2. Using a flat screwdriver, carefully pry it off and tighten the metal ring (clamp) holding the rubber seal of the hatch inlet.
3. Having bent the cuff, using a Phillips screwdriver or a tool with an asterisk attachment, we unscrew the fasteners holding the UBL.
4. By pulling the lock to the left, carefully remove it from its seat.
5. We check the dismantled lock with a tester. To do this, switch the multimeter to the “Resistance” mode. We apply one probe to the neutral contact, the second to the phase.The tester changes the readings - the UBL is working.
6. We apply the tester probe to the neutral and common contact. If “0” is displayed on the multimeter display, the UBL is faulty and requires replacement.
7. We disconnect the faulty lock from the wiring and connect a new part in its place.

After replacing the lock, return the clamp and rubber cuff to their original place, and run a test wash.

We eliminate contact breaks between the UBL and the control module

Very strong vibration of the washing machine, long-term operation of the household appliance in a damp room leads to disruption of the integrity of the contacts between the hatch locking device and the control module. In addition to error E40, a similar problem is indicated by a burning smell that occurs when starting the wash.

To troubleshoot the problem you must:

• carefully inspect the UBL contacts for breaks, burnt areas (additionally, the wiring is tested with a multimeter);
• clean damaged areas, solder breaks.

Restoring the operation of the control module

Very often, error code E40 (in diagnostic mode E43, E45) indicates that the reason for the lack of locking of the hatch doors lies in the control module. Sudden voltage surges or moisture entering the washing machine body lead to burnout of elements in the UBL circuit.

To diagnose and fix the problem, you must:

1. Remove the cover of the washing machine (unscrew the rear panel bolts).
2. Remove the powder receptacle, unscrew the fasteners in the opened niche, and remove the control panel from the latches.
3. Having carefully examined the control module, determine the burnt-out elements (damaged areas are distinguished by black color, convex capacitor caps), and resolder the necessary areas.

In the absence of knowledge, experience and skills in repairing the control module, it is better to entrust such work to the professionals of the service center.

How to prevent it in the future?

Prevent error E40 from appearing in an Electrolux washing machine A few recommendations will help:

• do not load the washing machine drum more than specified in the operating instructions for the household appliance (excessive sagging of the drum leads to stretching of the cuff, loosening of the hinges and breakage of the UBL);
• close the hatch doors carefully (excessive pressure can cause damage to the UBL and bending of the hinges);
• at the end of washing, always unplug the household appliance from the outlet (one sharp power surge is enough for the control module to fail).

Strict adherence to the rules of operation of the household appliance prescribed in the manufacturer’s instructions will help to maximize the period of trouble-free operation of the Electrolux washing machine.

Call the master

For those who are little familiar with the internal structure of the Electrolux washing machine, in eliminating the E40 error they cannot do without the help of a professional technician.

You can call a specialist to your home from the service center or use the services of private craftsmen (contacts are not difficult to find on the Internet). When filling out an application, you must provide the model name of the washing machine, the year of manufacture of the household appliance, and describe in detail the problem that has arisen.

Depending on what exactly caused the door to not lock, repairing a washing machine will cost from 1,500 rubles. up to 3000 rub.The urgency of order fulfillment increases the cost of the specialist’s services.

Adviсe

Gently pressing the hatch door with your knee in some cases helps to quickly eliminate error E40 on the control panel of the Electrolux washing machine.

Provided that all elements of the internal device are in working order, restarting the washing machine will help quickly eliminate error E40. Simply unplug the device and wait ten minutes., and then restart the washing process.
