I have a 7 yr old De Dietrich dishwasher - have been away for the weekend and come home to it just showing Test 03 OK. If I shut the door it whirrs away but does nothing. I cannot seem to shift it out of this mode, and have tried turning on and off several times. Nothing in the manual for this. Any suggestions please?
