Today my 7 year old bosch dishwasher stopped working. The machines makes a constant whirring noise as it fills and gulps the water back out of the drain hose. Co-incidentally at the same time the 3 digit LED display stopped working and is now blank. resetting the buttons has no effect, the machines keeps on filling and draining at the same time.

I wondered about taking it apart and looking at the float valve but can only see a few torx screws. Have taken them out but can't see how the lid removes to allow the sides to come off.

Any ideas/help appreciated

Was told it was the control board. Decided to get a new dishwasher.

the lid has a clip on the back corners u push then up and slide the top back at the same time. when u get the left panel off check the pressure switch the diaphram could be leaking air. if thats ok then check the sump for water if there is a leak into the sump the safety float cutts in but that useually stops the filling so only the drain pump is running. if thats ok then its in the control board in the door. let me know what u find.
