Hi. I had a fault code of A5 and read other peoples answers and did the same, which was hold down start button for a few seconds and the fault cleared. The problem I have now is that the water is not getting into the dish washer. Is this our fault i.e. plumbing or a machine fault although the dish washer is not showing any fault code, except salt light on although i filled the salt up.
