Need help on fixing my GE dishwasher GSD550T-60BW.
When we tried to turn it on by turning the dial, it hums fill the water but never start. It also have a little smell like burn plastic. The water is still there, that is how we know it fills the water.
Sounds like a motor problem
Remove the kick plate do not latch the door.
Remove the wires from the motor. Note which goes where.
You should see the cooling fins at the back of the motor.
Try turning these with a small screw driver, if the will not turn your motor is jammed.
Remove the sump cover (inside tub center).
Note how the internal filter goes, put it in wrong when you reassemble the unit and the chopper will eat it.
Check in the sump for debris or something wrapped around the chopper.
Be care often there is glass in the sump.
If you want to see better, remove the water from the sump, a turkey baster works good.
Just remember to add a quart or so of water before restarting the unit.
The seals in the pump will burn up if it is run while dry.
