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.

Replacement door interlock does not match existing 5-wire harness

The problem
The washing machine owner was trying to fit a new-style door interlock to an older block connector. The existing harness had five wires, but the supplied diagram only showed three, so the wiring change did not make sense.
Likely cause
The accepted reply indicates the replacement interlock is probably the wrong part, or at least not a clearly compatible substitute for the machine’s original door interlock.
What fixed it
Check the appliance model number and confirm the exact correct replacement door interlock part. If the part is genuinely correct, the supplied leaflet should clearly explain any approved connector modification. No confirmed wiring alteration or completed repair was documented.
Checks to try
  • Compared the existing 5-wire harness with a diagram showing only 3 wires
  • Noted that the new interlock looked very different from the old one
  • Advised to verify the replacement part against the machine model number

Safety: Do not bypass or modify the door interlock wiring unless the replacement part and fitting instructions are confirmed correct. Further diagnosis should be carried out by a suitably qualified appliance engineer.

It doesn't sound like a proper replacement if it looks very different and 2 wires are not used. You have to make sure you have the right replacement part. If you do then the leaflet should explain exactly what to do. Can you find the part you need on Ransom Spares using your model number and see if it's the same as the one you've bought?
