If your Frigidaire or Electrolux dishwasher is making loud noises, leaking from the bottom, or struggling to circulate water effectively, the circulation motor could be the culprit. This component, which includes the motor and impeller assembly, is responsible for moving water through the dishwasher during wash cycles.
Fortunately, replacing it is a straightforward DIY task that you can complete in about an hour.
Diagnosing Circulation Motor Issues
Before jumping into the replacement process, it’s helpful to confirm that the circulation motor is indeed the problem. Common signs of a failing circulation motor include:
- Loud Noises: Grinding, humming, or rattling sounds during the wash cycle.
- Poor Cleaning Performance: Residue left on dishes even after a full cycle.
- Leaking Water: Leaks coming from the bottom of the dishwasher.
- Error Codes: Some models may display error codes indicating motor-related issues.

- Carefully slide the dishwasher out from the cabinetry.
Removing the Old Motor
- Lay the dishwasher on its back on a towel or flat surface to access the underside.
- Locate the circulation motor mounted to the sump housing.
- Press the locking tabs and detach the two wiring harness connectors from the motor.
- Use a Torx T20 screwdriver to remove the two screws securing the motor’s mounting bracket to the sump housing.
- Wiggle and pry the old motor assembly free from the o-ring seals, twisting and rocking it if needed.
- Remove the two rubber o-rings from the old motor and set them aside for reuse.
- Clean the o-rings thoroughly.
Installing the New Motor
- Apply a few drops of petroleum jelly to the o-rings for easier installation.
- Place the larger o-ring in the lower channel and the smaller o-ring in the upper channel of the new motor.
- Press the new motor into the sump housing, gently rocking it to ensure it seats properly into the o-rings.
- Reattach the wiring harness connectors to the new motor terminals, ensuring the locking tabs click into place.
- Reattach the mounting bracket over the new motor and secure it with the Torx screws.
Reinstallation and Testing
- Slide the dishwasher back into the cabinetry, pulling the drain and water lines through.
- Reconnect the drain hose to the plumbing or garbage disposal and secure it with the clamp.
- Reattach the water supply line to the inlet valve and tighten the nut.
- Open the shut-off valve to restore the water supply to the dishwasher.

Maintenance Tips for Longevity
After replacing the circulation motor, regular maintenance can keep your dishwasher running smoothly:
- Clean Filters Regularly: A clogged filter can strain the motor, so clean it every few weeks to maintain proper water flow.
- Use High-Quality Detergents: Avoid cheap or abrasive detergents that can leave residue or damage internal components.
- Run Hot Water Before Starting: Running hot water through the kitchen faucet before starting the dishwasher can improve cleaning performance and reduce stress on the motor.
- Inspect for Leaks: Periodically check hoses and seals for wear or damage to prevent leaks.
- Avoid Overloading: Overloading your dishwasher can restrict water flow and overwork the motor.
