Didn't look into this topic for a long time. Thanks a lot for the correction that the lock is bimetal operated and not via solenoid. This is also interesting from an engineering point.

I think your remark on reduced safety of operation cannot stated enough:

Know what you are doing and what the results could be. If you repair something and introduce risks make sure everyone involved knows about them.

I don't think your problem is related to this interlock.

You are right, if the bimetal (thanks for the correction in the other comment) actuator is powered the switch contact will indicate the locked door, so shorting it might be a dangerous fix, but if your spinning cycle is messed up I'd look at other points of failure. If the switch was broken your machine would either not start at all, or run even with an open door.
