Got an LG F4MT07WE S/N-011PNHN22545, machine can run for days or weeks then goes dead, if you unplug it and leave for a day or 2 it works fine again for a short time, sometimes you need to disconnect the main pcb, leave it for a short time and after its connected back up it works ok, anyone came across this before as am thinking the main pcb.
Smeg Dishwashers used to do this if there was an earth leak somewhere, it charges the capacitor on the board , may be worth checking before you go down the board route ??
I did do that and it tested ok, its only about a year old or so but no warranty as its in a commercial place, would anyone have part number for the board please
