I have a Whirlpool ADP 4403 dishwasher. it stops 5 mins into a cycle, the green light starts to flash. .flashes 4 times then a pause. I have topped up the salt and rinse aid . I have pressed and held the start button but it continues as be for . Runs for 5 mins then and the green light starts flashing.
any ideas what this fault code means?
