Having moved house and stored nearly new Hotpoint FDL 570G.R dishwasher for a while, connected into new house and found it won't work. It sounds like water is entering initially then drains and all lights start flashing - Salt, Rinse Aid,Washing,Drying and End lights. According to 'Troubleshooting' page in Manual it should be Water inlet filter blocked - that is clear. Water inlet pipe is new , unkinked and water runs freely, I have tipped the machine back in case it was the anti-flood device. My only other thought is the Water solenoid valve - could it be this, how can I check please?
