I noticed today that when I turn on keyboard or when I m playing the pitch wheel keeps on fluctuating the value even when it is at rest . The value ranges between 49 to 72 . Do not know what’s the issue , is it dust or some other issue . Kindly help

I just experienced this problem on my MkII 61 key.
Pitch wheel kept drifting (down) and seemed to spontaneously fix itself-- but reverted back to drifting down
