Hi, I have a problem with an Indesit IDF125 dishwasher. It will start a program as normal, fills up with water, then drains, but then I get two flashing green lights and it won't go any further. I have been restarting it and it has been working after several attempts but now it just keeps failing with the flashing lights. Any ideas appreciated please, or if there's any part of it that I can hit with a big hammer. Thank you.
