How To Clean A Dishwasher Motor?

22.01.2024

You may run into an issue of your dishwasher not cleaning dishes well or hearing water coming in, but it won’t start. This may happen to any dishwasher brand or type, but such malfunctions usually occur with American brands. In this article, Jacob Dillard, an engineer at Appliance Repair Expert, will tell you how to clean your unit’s motor properly. Please only carry out this procedure if you are sure that your appliance can take in and drain water.

What Tools Will You Need?

This is an intermediate repair and requires no special tools other than bits, drills, screwdrivers, spanners and pliers. In addition, have an old towel or blanket ready to place under the dishwasher to avoid scratching the floor during the repair.

  • Bits
  • Drills
  • Screwdrivers
  • Wrenches
  • Pliers

How To Remove The Dishwasher?

Remove the dishwasher from under the countertop by unscrewing the screws on the sides or top of the appliance. You should be able to pull the unit out from its spot quite easily unless the levelling legs or hoses may be in your way. You may need to lower the front or back legs with a wrench to pull out the unit. Sometimes, the water supply hose must be disconnected if it isn’t long enough.

Best Way To Clean The Motor In Your Dishwasher

Carefully place a blanket under the machine and lay it on its side to allow enough space to access the dishwasher from below. On some models, you may need to remove the bottom panel to access parts.

Once you have located the pump, remove it from its original position. On most models, it is not secured with screws but with a thread that can be twisted. Inspect the pump casing and locate the bracket rod that needs to be pressed to remove the motor. Usually, an arrow on the pump indicates the direction in which to move.

After removing the motor, disconnect it from the wiring harness and check for any debris or dirt. Clean it thoroughly. If you find a large accumulation of dirt, clean it off and reassemble the device to test it. If you don’t see any dirt, the problem may be inside the motor if you don’t find any dirt. Locate the screws on the motor and unscrew them.

Once inside, use paper towels and water to clean it inside and out as best you can. Once the motor is clean, screw it back on. Do this cleaning every couple of years.

Cleaning the dishwasher circulation pump motor can help restore proper cleaning efficiency. At the same time, the dishwasher drain pump motor can also become clogged, resulting in a lack of water drainage. 

If the problem persists after cleaning, it may be something else, so contact a technician from Appliance Repair Expert.
