Hi, so the sustain pedal on my Kawai mp11 seems to be always sending some values even when not pressed. most of the time above 50. The sustain builds up quickly, unplayable this way.

What could be the trouble? Dust on the sensors?

I tried to open it, removed the screws, but I can't get that back plastic cover to access the pedals, any tips?

Thanks.
