Wrong or incompatible door interlock fitted on IWD7145UK
- The problem
- After fitting a new door interlock on an IWD7145UK washing machine, the machine would not start a wash. The indicator lights came on, but the door would not unlock. The replacement interlock was a different size and had different terminal markings: the new part was marked 2-3-4 and the old one 3-4-5.
- Likely cause
- The strongest diagnosis in the discussion is that the replacement door interlock was not the correct part for this machine, either because its operation/size differed so the door catch was not actuating it properly, or because the wiring arrangement did not match the original interlock.
- What fixed it
- Recommended action was to stop using the mismatched interlock, identify the correct replacement door interlock for the IWD7145UK, and only fit the proper part. If the terminal functions could not be identified with certainty, the advice was to obtain the correct interlock rather than guess the wiring. No confirmed repair outcome was posted.
- Checks to try
- Observed that the replacement interlock was a different size from the original
- Compared terminal markings: old interlock 3-4-5, new interlock 2-3-4
- Confirmed symptom: machine lights came on but a wash would not start and the door would not unlock
- Parts or tools mentioned
- Replacement door interlock
Safety: Incorrectly wiring a door interlock can damage the main PCB. Further diagnosis should be carried out by a suitably qualified appliance engineer.

Is it one you were sent as a proper replacement? If it's a different size it may just not be being operated by the door catch.
If you wire it up wrong it can blow the main PCB, you might have been luck that the combination you connected up was just the one where it doesn't work as opposed to the one which connects a live and neutral together - BANG
If it wasn't meant for this machine it's not a good idea to fit it but my article here describes how they work which may help you find the right combination of wires - how does a washing machine door interlock work?
If you can't determine which connection is which try and get the right door interlock 4washerhelp spare parts
