Hi i have a problem Hotpoint BFV620X dishwasher which is flashing lights 1 and 3 which is filters blocked, machine runs the pump and then fills quickly to a decent level (but not what i think is enough for washing) then flashs up the code. I originally replaced the PCB which did about 3 washs before doing the same thing again. I checked pressure hose, heater and for water in the base but all seemed ok can anyone give me some pointers? what am i missing? thanks Peter 🙂
