Re: no power to fill valve
Hi,
Check for water in the sump which will activate the anti flood device (polystyrene float with a microswitch above it). This would cause the PCB not to initiate filling.
Check security of fill valve connectors to PCB. You’ll have to trace the wiring from the valve to the PCB.
Check for voltage where the fill valve block connector attaches to PCB.
Check that the machine has drained thoroughly. If not, check the outlet for blockages and the drain pump for obstructions, continuity and voltage.
That should keep you busy for minute or two 😉
