Re: Diplomat adp8322 fault
F11 relates to the Optical Water Indicator – this is not fitted to your appliance. 7 flashes relates to the flow meter in the side tank, cleaning the contacts at the little pcb and at the computer end will often sort it. 4 is the water level sensor in the sump – the black grid. This fills up with crud. Cleaning it properly involves removing it (twist fit from underneath – power off) and using plenty of very hot water and an old toothbrush. If functioning, the diaphragm inside can be heard operating the microswitch.
These questions have been answered repeatedly in this forum for both Diplomat and Whirlpool dishwashers, which may be why a reply has been slow in forthcoming. The Moderators get fed up with typing the same stuff out over and over again.
If none of the above works for you, you’d better get an engineer reasonably quickly, or you win the Marigolds on Christmas day. Use the link below for a UKW engineer in your area.
