Thanks for the response,
Original issue still the same.
I have a GE Profile dishwasher, Model #PDW9980N20SSAfter complete cycle with heated dry, low pitch humming noise coming from
Upper/center of door (inside). (About the same time this started , the 3 digit time
Display started giving erratic readings.)
When I open door, the sound level increases 3-4 times. When door is closed, reverts
back to the low pitch tone/vibration.
This will continue until the reset button is pushed 2 times.Assuming (2 unrelated issues: noise & vibration) it was either the WD21X10367 Main Control Board or WD34X11158 Keypad.
Replaced both. Sound/Vibration remains.
Inspection of the Blower assembly, WD26X10056, shows rust and corrosion.
There is also condensation (in area of 3 digit display) on touch pad.The washer works fine except for the noise issue...something not shutting off at completion of cycle...
Process of elimination,
The only thing that would be a continuous noise producer in the top left/center is the blower motor
I put one on order earlier this afternoon. I'll let you know the outcome when I get it installed.
