Bah.
Why do things like washing machines choose the most inconvenient time to die?
We're off on holliberries tomorrow, and we were doing a load of washing this afternoon.
The machine packed in mid-way through the cycle.
Extracted the wet load, and Mrs. F took it round to my brother's house to finish it up whilst I had at the machine.
Error E40 .. Tappity-tap... Hmm, door interlock failure.
Strip it down.
Hmm, the cable loom connector is badly burned where it connects to the interlock module.
<Orders new interlock module and cable assembly.>
If the push came to the shove, I could just cut off the burned connector and solder the wires directly onto the parts of the interlock assembly.
Interesting thing, the interlock assembly.
I expected it to be just a simple solenoid, with a contact to sense the position.
But no.
It's a wee ceramic heater pressed against a bi-metallic strip which pushes the locking pin out.
And a curious ratchet-wheel with ramps on it which is rotated by a solenoid repeatedly prodding it which retracts the locking pin.
A most curious design.
Presumably to allow it to fail-open after removing power for a few minutes.
