Can anybody please offer any guidance with the following problem.

The power button doesn't work but when turned off at the socket, left a few seconds and turned back on, the lights briefly come on.

The history so far is here.

has that machine got a brushless motor if it hasnt check the state of the motor brushes also check the condition of the mains filter as they are notoriously un reliable on that model

Thanks James,
The problem is fixed - I attached my multimeter to measure the voltage across the on switch and as I turned the power on at the wall, the machine came on and stayed on and now seems to be fully functional again!
I can't be sure if it was connecting the multimeter that fixed it or one of the following:
  • Measuring the voltage across all diodes (using the multimeter diode setting).
  • Measuring the voltage from base-to-source and base-to-collector on all transistors (using the diode setting).
  • Measuring the source-to-collector resistance on all transistors.
  • Allowing enough time to pass for something to dry out (although there was no evidence of water).
  • General movement of cables if there is a broken one (including taking out the motor control board to check the fuse).
Now when I turn it on at the wall, it doesn't light up until the on button is used.

edge connectors are a major problem on washing machine pcbs a lot of faults can be cured by just cleaning the contacts on the board a use a commutator cleaning stick for this or a fibreglass pencil
