Finding out what’s wrong with your appliance can be easy as soon as you know the spot thats causing the problem. If you want to figure out your own appliances and how to fix them yourself, here is an excellent resource to help you find the problem, find the parts needed and then how to fix your specific appliance.
Below are a few popular problems experienced with certain appliances:
If the motor isn’t turning or working, the unit won’t drain. First check to be sure you have power to the dishwasher. If the motor hums but doesn’t turn, it may need to be replaced.
Some dishwashers are susceptible to getting stuck if you don’t run them regularly. If you haven’t run the dishwasher for more than a week, you may need to manually spin the motor to free it up. If the motor is defective, you need to replace it. Dishwasher motors can’t be serviced.
As motor bearings wear out, they can become quite loud when the motor runs.
Your dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support.
Look for an impeller–a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them.
