Door locks if machine is plugged and starts only for a second
We have an Indesit IWDC6125 UK washing machine.
A few days ago it kicked off the fuse on the switch board and we couldn't open the door. I have managed to open the door from inside and remove the door-lock. I have opened up the lock and it was burned inside. I have ordered a replacement door-lock. I fitted the new lock and after the door is closed the washing machine starts the program (let some water in) for a few second and stop. The other issue is that as soon as you plug in the washing machine the door lock is powered so if you close the door it locks without starting a program.

Indesit IWDC6125 UK locks door on plug-in and only starts briefly after door-lock replacement
- The problem
- The washing machine originally tripped the household fuse board and the door could not be opened. The original door lock was removed and found to be burnt inside. After fitting a replacement door lock, the machine locked the door as soon as it was plugged in, and when a programme was started it only let in some water for a few seconds before stopping.
- Likely cause
- The strongest diagnosis in the discussion is that the original door-lock short circuit may also have damaged the main PCB, or there may be a wiring/connection fault between the door lock and the main PCB. Exact failure was not confirmed in the thread.
- What fixed it
- Recommended action was to inspect the PCB for blown printed circuitry and avoid fitting a replacement PCB without proper testing. The original poster removed the control PCB and sent it away for test and repair. No confirmed repair result was posted.
- Checks to try
- Original door lock opened and found burnt inside
- Replacement door lock fitted
- Control PCB removed and visually checked for obvious damage
- PCB sent away for test and repair
- Parts or tools mentioned
- Replacement door lock
- Control PCB
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hello there. Unfortunately it sounds like when the door lock shorted out it may well have damaged something on the main PCB. Or there's a possibility that there is a problem with the connections or wiring between the door lock and the main PCB. You might have a look at the PCB to see if any printed circuitry is blown. However, I would caution against fitting a new PCB. They are very expensive parts and I wouldn't replace one without testing the washing machine properly with an installation test meter to make sure there isn't anything else wrong.

Hi Andy and All,
Thanks. I got to the similar conclusion. I have removed the the control PCB but couldn't see anything unusual. So I have sent the board for test and repair (~£33 on Ebay). I hope I will get some information about the fault and will know more what do I need to check.
This hole think happened during a program close to the end. I think it is a silly question because the door lock connected to releases but is it possible that the current changing on in the lock during a program. So when the machine got to the spinning which need more power and than boom.
By "installation test meter" test do you mean a PAT test?
Thanks anyway, I will update this post after I get the PCB back.
Thanks,
Peter
Hello Peter. I think they both do the same job but they are different meters. Basically they use 500 V DC to test for installation leaks to earth. Door locks have been known to short out inside and go with a bang.
