I have a GE rofile PFS23KSHAFSS. The water dispenser just started to come on by itself without the pad being depressed. I can stop it only by locking it or unplugging it which leads me to believe it is an electrical problem. Frankly, I'm a little unsure exactly how the unit works as the pad does not seem to be wired to anything. There is a sensor on the back of the trim display (BS PCB Assembly). My thinking is it could be that piece or the control panel. Is there any way to check this? DO you have any idea what it might be?
