I have an Ariston AFA250UK dishwasher that has developed a fault. At the start of the cycle the dishwasher begins to fill and then stops, with water left in the bottom. I have checked the filters. There is a fault light flashing rapidly, which, according to my booklet that came with the machine, should tell someone what the fault is. Does anyone out there know? It is the ‘wash’ light that is flashing. I have a bank of four lights and it is the second from the left that is flashing. Could someone tell me what this means?
