Beeping and flashing on diplomat adp8322 dishwasher?

Hi, I have a fault on my diplomat adp8322 dishwasher, I have read previous questions and mine seems to be very similar - with flashing and beeping, where the answer is for 3 or 4 beeps. My actually does 16 in a row. Please could you advise which fault this determines and what can be done to repair it.
Thank you so much for your help
