I have roughly a two year old washing machine and I received an error 52 code. Checked to see what is was and found it to be a bad signal from the tacho generator. I took it apart tested everything fine and so I cleaned strainer that goes into pump put it back together and still problem. I attempted to enter diagnostic mode and now my machine is acting badly. It changed all the settings and when I attempt to run it does a few things and resets. The error is still there and im unable to revert it to its original settings. Please help me...when I attempt to enter the diagnostic I do as it says in the manual and wont enter.
