my hoover aaa class hdn7102 dishwasher is stucked in hygiene 75degrees program.. it shows at the countdown monitor the number 23 (which after some minutes went to 22) and does nothing.. I tried many times to switch it off and then back on,I put out the electricity cable,I left it like this for one night but when I turn it on it always shows the same thing without doing nothing.. I think that is something wrong with its computer.. Can you please tell me what to do?
