Been to this anomaly today with an F05 fault reported by customer, 1 1/2 yrs old!
No blockage in pressure tube or pipe to tub.
sump and pump clear, pressure switch has resistance so suspect that ok.
It won’t turn on/off by button- only socket switch, there’s no programme selection, but sometimes is for a few seconds then stops!
Sometimes no display at all.
Erm- what else. Customer reported it tripped the electrics, machine got very hot. Checked heater, resistance and meggered ok, disconnected heater & motor- still no difference.
Main and programme module show no signs of damage.
help please! TIA Darrell
