My dishwasher is cheap, old, reliable, but this morning it wouldn’t do jack.
Instead of starting the normal cycle, it just hums. It doesn’t fill with water, crank, or anything…just hums. When I say “hum” I mean “an electric motor trying to do something but not doing anything”-hum like if a garbage disposal were stuck. Fearing I’d burn the thing out of cause a short of some kind, I turned it off after 10 or 15 seconds. I tried later in the day – no luck.
Turn power off to the unit
Remove the kick plate
You will see the end of the motor, with a small screw driver try to turn the armature by moving the motor’s fan blades.
If you cannot the motor is jammed.
Remove the sump cover from the inside middle of the tub.
Note how the inside baffle goes, put it back in wrong and the chopper will eat it.
Check in here for debris or something wrapped around the chopper.
Be careful often there is glass in the sump.
If the sump is clear and the the motor will not turn you probably need a new motor.
It comes with the motor, pump and solenoid, will run you about $125.00
