Washing Machine Door Interlock

The door interlock is an electronic device that is designed to give a time delay of approximately 2 minutes before the door of a washing machine can be opened once the wash/drying cycle has competed. Door locks should be checked regularly to ensure that they are working correctly.  During the cycle the door should remain locked; as it is can be extremely dangerous if this is not the case.

The common fault when a door interlock fails is that the washing machine will not start.  There will be power to the washing machine, which is can sometimes be ascertained by the light (if present) being lit up on the front fascia panel.  However, when the door is closed and the wash/drying cycle is selected and started the machine will appear 'dead'.

    Exactly right for the machine

    This door switch was easy to find on their listings and even easier to fit. (I did watch the video although I thought I could do it without and hey presto it was very easy.) It fitted a treat and worked perfectly. Highly recommended.

    Part exactly as described. A problem with the door interlock may be due to overheating of the circuit - in which case it is strongly recommended that the wiring harness from the door interlock to the control panel is replaced at the same time - Stock Number: ES1075058

    My AEG washing machine stopped working showing an error code indicating a fault with the door. Not really sure what was wrong with the door (it opened and shut ok) I came on the Espares website, watched the video about how to replace the door lock, and decided to buy and fit a new door lock. I don't have a clue about how washing machines work or engineering but replacing the door lock was simple, thanks to the instructions on the video. And my washing machine started working again! Much cheaper than calling out a repair man! I'm very pleased.

The AEG Lavamat 72640 is showing an E40 error, I have checked the manual for the E40 error and done the following (replaced main fuse, check door is closed firmly, checked drain tap at the front bottom right). But the washing machine is still showing an E40 error and won't allow for the wash to start, it turns on but won't start on any wash cycle.

    E40 is a door lock error and may need replacing, for more information see our video:

Answer this question

The interlock clicks like it always has when I start the machine, then beeps and says E40. Is there a way to tell if the interlock is the problem and needs replacing? Its a John Lewis JLWM1407

    It is likely a new lock will resolve the problem.

Answer this question

I don't know if you can help me diagnose a faulty part but I do not want to buy a spare to find that there's nothing wrong with the one I have. My washer dryer has died completely with no lights or LCD display at all. I have taken the PCB off with no signs of burn out and removed the door switch and I suspect/hope it is the door switch. What I want to know is is the door switch faulty or not. It Has four wires coming out in two pairs one has a red connector on it which has 1,800 ohms across it whether the door is open or shut - maybe this is the thermocouple heater element? The other connected with black is constantly open circuit. Faulty switch? Is this the correct status for these connectors if not I Wil assume it is broken and I'll order the part from you. Please let me know if the door switch is faulty and I'll order a spare and give you a constructive review as this would be genuinely useful in addition to your great videos which I wish I'd watched before taking the whole front panel off to remove door lock :-/

    If your machine has this lock it is based on an Electrolux or Zanussi. These have a solenoid door switch that make a loud click locking and double click when opening. A faulty door switch would not normally stop these machines from lighting up so it is unlikely if dead that this is the problem.
