The dishwasher is starting to beep as soon as you start a program and close the door. It sounds like it´s doing something the first 10 seconds then i just stops, but the beep continues. It flashes 2 times.
I noticed it was water under the maschine. After I cleaned that and made a reset it still behaves in the same way.
There’s a leak into the tray under the machine. The water is operating the flood protection system (A polystyrene float and microswitch mechanism). Power off, drain the tray and try again. Leave the front lower cover panel off to observe if there is a leak.
