I have a fault code on an hotpoint WDPG 9640, code H20. The washer still completes the cycle but around 70 mins into cycle (cycle used is cotton 40,Eco) it starts to beep and the fault code H20 appears. It then stops beeping and displaying the fault code after around 20 mins and finishes the cycle fine.
I've checked the hoses and nothing seems wrong.
Also, if the machine is put on a fast wash it washes fine and no code appears.
Can be taps turned off, faulty fill valve, poor water pressure, small filter to the valve clogged, not draining correctly due to partial pump filter blockage or just because it is an Indesit with iffy electronics.
