Hi, I am hoping you can help me. Replaced the door lock as the machine would not start. But after replacing, it still would not start.

I am almost certain its not the door, as if I connect the switch up, and push the switch as if the door was engaged it still doesn't start.

I can measure power on the connector. Also if I short out pins 2 & 3 on the connector the machine works.

I can also measure the coil on pins 1 & 3 with my ohm meter.

At a bit of a loss as to what to check for now.

Machine is working with the pins 2 & 3 shorted. But not ideal as the door can be opened with it washing!

The picture shows both switches, the one on the right is the Old one.

Many Thanks for reading this.

Mark

Solution Summary

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.

Beko WM74135W will not start unless door-lock pins 2 and 3 are shorted

The problem
The washing machine would not start. The door lock was replaced, but the fault remained. The machine would run only when pins 2 and 3 on the door-lock connector were shorted, leaving the door able to open during washing.
Likely cause
Most strongly supported diagnosis is a door-lock circuit problem. The accepted reply pointed to the door lock itself, or the door/latch not mechanically activating the lock. However, another reply noted that a second lock having the same symptom is unusual, so the exact failed part was not confirmed.
What fixed it
Suggested action was to recheck that the door lock is being correctly activated by the door/latch and to consider that the replacement lock may also be faulty. The original poster said they would try obtaining another lock, but no confirmed repair was posted.
Checks to try
  • Door lock replaced
  • Tested the lock while connected and manually pushed the slider as if the door were engaged
  • Measured power at the connector
  • Measured the coil resistance on pins 1 and 3
  • Shorted pins 2 and 3 on the connector and confirmed the machine then worked
Parts or tools mentioned
  • Replacement door lock
  • Ohm meter

Safety: Do not bypass the door interlock in normal use. Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hi if the washing machine works when you bypassed the door lock it must be the door lock? If not the lock then the door and door latch are not activating it?

Hi Andy, thank you for replying.

I have tested the door closing the switch, with it plugged into the connector, and pushing the slider across.

May be I was unlucky and the new lock is faulty. I will see about getting another one.

Thanks again.

Hi. It’s very unusual for a new part to be faulty especially if it has the same symptoms as the original one. It’s more likely to be something else. Is it definitely wired up ok? Separate wires or a connector plug that can only fit one way?
