Hotpoint Wf541 Door Interlock Broken Twice

Hi, I have a hotpoint WF541 washing machine, and halfway through a cycle the 'door locked' light started flashing, the cycle stopped, and the only way to get the door open was to turn it off at the mains for a few minutes. If I tried to start a new cycle the 'wash'light came on and the door locked, however the door lock light didn't come on and the cycle wouldn't start.

I figured the door interlock was broken, so bought a new one. I fitted it, and everything now worked perfectly. However after putting a new cycle on, it got halfway through the cycle and the same thing has happened again to the new door interlock. I.e. I press start cycle, the door locks but the door lock light doesn't come on. The cycle doesn't start and the only way to release the door is to turn the mains off for a few minutes.

So, was I just unlucky and got a duff replacement interlock? Can the machine have a fault where it damages interlocks? Could the problem be something else, and it was just chance that it seemed to work after fitting the new interlock? Any help appreciated!

AI-generated from this discussion

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

Hotpoint WF541 stops mid-cycle with flashing door locked light; repeat after replacing interlock

The problem
Hotpoint WF541 washing machine stopped halfway through a cycle with the door locked light flashing. The door would only release after switching off at the mains for a few minutes. After that, starting a new cycle locked the door and lit the wash light, but the door lock light did not come on and the cycle would not start. A replacement door interlock briefly appeared to cure it, but the same symptoms returned partway through the next cycle.
Likely cause
The discussion’s strongest diagnosis is that the replacement interlock was unlikely to have failed in the same way again. Because the door still locked, the door catch and interlock activation were thought to be working, pointing instead to a fault elsewhere in the machine, possibly the main PCB or related circuit.
What fixed it
Professional diagnosis was recommended rather than fitting more interlocks. The accepted advice was to have the machine checked by an engineer for a fault beyond the door interlock, potentially on the PCB. The exact repair was not confirmed in the thread.
Checks to try
  • Observed door locked light flashing mid-cycle
  • Confirmed door only released after power was turned off at the mains for a few minutes
  • Replaced the door interlock
  • Observed that the door still locked but the door lock light did not come on and the cycle would not start
Parts or tools mentioned
  • door interlock

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

The least likely explanation is the new door interlock has the same fault. If the door locks it indicates the door catch and interlock are being activated ok. After the door lock is activated it should pass power onto the rest of the machine through the main pcb so maybe there's a fault somewhere else on the machine or pcb. I would get an engineer in.

Thanks for the reply, I've booked an engineer, I was just a bit confused that replacing the interlock seemed to fix it initially.

Cheers, let us know what happens. You said it only fixed it until it got to the middle of the cycle where it failed last time so maybe the fault only occurs mid cycle.
