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 entry into the diagnostic system was successful), a code will appear on the display that pinpoints the cause of the washing machine malfunction:
- 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 the 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 “Wash End” 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 .
Error E40 of the Electrolux washing machine: meaning and elimination
Error E40 appears on the display of the Electrolux washing machine before starting the wash, after closing the door and starting the program.
As a rule, if this code appears on the display, nothing further will happen, no matter what algorithm is chosen: water will not be drawn in, the drum will not rotate. In any case, there is no need to panic.
The problem can be caused by the simplest reasons, which will take a few minutes to eliminate. Although you may have to tinker.
If your attempts to return the washing machine to working condition are unsuccessful, a specialist from our service center, who repairs washing machines at home in Kazan, will come to your aid almost at any time.
What does this code mean?
For all SMA Electrolux models, this alphanumeric combination indicates a problem with the hatch locking device. This code is general. In order to more accurately identify the culprit of the problem, you need to enter service mode. A specialist can handle this more professionally, but in general the sequence of actions is as follows:
- Simultaneously press 2 paired buttons on the right side of the control panel.
- After that, without releasing them, press the large side orange button. Continue applying pressure until the indicator lights come on.
- E41 - the hatch is not tightly closed.
- E42 - the lock is faulty.
- E43 - failure of a part in the control module responsible for the locking device.
- E44 - the drum door sensor is acting up.
- E45 - problems with the wires connecting the UBL and the control module.
This method is suitable for units without a program selector. If there is one, you just need to simultaneously press and hold the 2 rightmost buttons for a while. As a result, the specified error code will light up on the display:
Solving the problem yourself
The simplest thing you can do yourself is to try to close the hatch door more tightly. This alone can help. Or try opening and closing it again. Another recommended way to get rid of the problem: after starting the selected algorithm, press the hatch door and do not release until a click is heard and a lock sign appears on the display.
The appearance of error E40 sometimes occurs due to voltage fluctuations. Many owners of Electrolux washing machines have noticed the sensitivity of this equipment to power grid indicators. Notice the blinking light bulb in the room. If this happens, and error E40 appears at this time, you should wait until the voltage in the network stabilizes.
If the above actions do not lead to success, you will have to check the UBL, the wiring leading from it to the electronic module, and the module itself one by one. In the latter, the triac responsible for the operation of the lock often fails. Finding this part requires a good knowledge of electronic circuits.
In addition, as our workshop’s long-term practice shows, there are times when error E40 flashes on the display, but the problem lies in details that are theoretically not related to it. There was a case when the problem was in the motor.
From all this it follows that the optimal solution is to contact our Electrolux service center!

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 to do when the washing machine signals a malfunction with error E40 is to open the door, check the rubber seal of the hatch for stuck debris , and close the hatch door again (press until it clicks).
Additionally, check the condition of the hinges (door misalignment can also trigger error E40). It is enough to tighten the fasteners that have become loose over time so that the hatch door fits hermetically to the body of the washing machine again.
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:
Open the hatch of the washing machine.- Using a flat screwdriver, carefully pry it off and tighten the metal ring (clamp) holding the rubber seal of the hatch inlet.
- Having bent the cuff, using a Phillips screwdriver or a tool with an asterisk attachment, we unscrew the fasteners holding the UBL.
- By pulling the lock to the left, carefully remove it from its seat.
- 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.
- 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.
- 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.
Before starting work, you must make sure that the washing machine is disconnected from the power supply.
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:
Remove the cover of the washing machine (unscrew the rear panel bolts).- Remove the powder receptacle, unscrew the fasteners in the opened niche, and remove the control panel from the latches.
- 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.
Causes of error, related ciphers
E40 is more of a standard error, which indicates a malfunction of the door locking device. The control board of the Zanussi machine has a diagnostic mode, which you need to enter in order to most accurately determine the causes of the problem. If your device is not equipped with a software selector, the procedure will be slightly different:
- In the picture below you will see two keys on the right under the number 1. Press them at the same time.
- Hold the buttons under number 1 and simultaneously press the button under number 2 to turn on the washing device. Press and hold the keys until all machine indicators begin to flash.
If your washing machine is equipped with software, then, as you said, you just need to enter the diagnostic mode. To do this, hold down the two buttons on the right and hold them for a few seconds. If you do everything correctly, E40 will disappear from the display and one of the other error codes will appear instead of this code:
- E41 - This is a fault code informing the user that the closed hatch is leaking.
- E42 - indicates a malfunction of the UBL.
- E43 - The triac, which is responsible for the operation of the hatch locking device, is broken.
- E44 – drum door opening sensor is faulty.
- E45 - there is a special electrical circuit between the target triac and the blocking device. E45 indicates a malfunction of this part.
Once you have figured out why your washer is malfunctioning, you can proceed to the next troubleshooting steps.
How to prevent it in the future?
Several recommendations will help prevent the occurrence of error E40 in the Electrolux washing machine
- 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 a 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.
If the “specialist” demands the full amount to be paid without even starting the repair (at the diagnostic stage), you should refuse such services. Full payment is made only upon completion of the repair, after a test run of the washing machine.
