I'll take a look at the link you've provided. Hopefully will provide a way forward.
Interestingly, and I don't know if it's related, but twice I've held down start and skip together and started the machine, and it then cycles through the leds and 7 segment display (which all check out ok), then when I switch the machine off, switching it back on makes it display an error message, didn't get a chance to view it and can't remember what it said - maybe E55, then it caused our ring main electrics to trip out.
Don't know if that's related to the fault.
