Re: Hotpoint BFI680 Fault Code 5&7
If you mean you have lights 5+7 flashing then the fault is in the heater circuit.
It could be heating element, connections, module, relay or pressure switch.
You need to unplug and drag the machine out and then test the heating element for resistance and continuity with a megger or suitable multimeter.
If the heater is OK then its 99{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} certain the control PCB is faulty.
