How to Service a Water Pump on a Frigidaire Dishwasher


In addition to saving you the trouble of washing dishes by hand, using a Frigidaire dishwasher is beneficial in that it sterilizes your dinnerware by dousing it with water that's too hot for contact with human hands. However, if a defective water pump is impeding your dishwasher's ability to drain, the water it retains can lead to an unsanitary buildup of mold and bacteria --- resulting in far from sterile conditions. Although the water pumps in today's Frigidaire dishwashers contain no serviceable parts, replacing one is relatively easy and won't break your bank --- providing you do the work yourself.

Things You'll Need

  • Phillips screwdriver
  • Towels
  • Pliers
  • New or refurbished water pump
  • Locate the circuit breaker box for your house or apartment and turn off the breaker that corresponds with your Frigidaire dishwasher.

  • Remove the two screws that hold the lower front access panel in place with a Phillips screwdriver. On most Frigidaire models, the screws are located on top of the panel, just below the dishwasher door.

  • Grasp the access panel with one hand on each end and pull it toward you in an upward motion to remove it. Doing so will reveal the water pump, which will be connected to a drainage hose with a hose clamp.

  • Place a towel under the water pump and one or two more on the floor in front of the dishwasher to soak up the water that will likely be released when you disconnect the water pump.

  • Squeeze together the two interlocking tabs on the hose clamp using pliers. As you do so, slide the clamp down the hose away from the water pump. Pull the hose away from the pump to disconnect it.

  • Locate the plastic harness that connects the electrical wires to the pump. Disconnect it by pushing its locking tab inward while pulling up on the harness.

  • Reach behind the water pump and locate the locking tab that secures it to the dishwasher housing. While pushing the tab inward, turn the pump counterclockwise and lift it out of the dishwasher.

  • Insert the replacement pump into the locking sleeve from which you removed the original. Turn it clockwise until the tab engages and it locks into place.

  • Fit the wiring harness into its appropriate slot on the replacement pump, making sure it locks into place.

  • Slip the drainage hose over the water valve on the replacement pump. While squeezing together its interlocking tabs with pliers, slide the hose clamp back into position and release the pliers.

  • Remove the towel from beneath the water pump and replace the access panel. Secure it with the two screws you removed earlier.

  • Clean up any spilled water from around your Frigidaire dishwasher and re-engage the circuit breaker.

Tips & Warnings

  • Because there are dozens of different types of dishwasher water pumps available, make sure the one you purchase is compatible with your specific Frigidaire model.
  • Working with electricity, especially around water, can be very dangerous. After disengaging the circuit breaker, it's a good idea to try turning on the dishwasher to confirm the power has been cut.
  • Dishwashers are specifically designed to prevent water from coming into contact with their electrical components. If you accidentally get the wires or other electrical components wet when installing your new pump, it would be a good idea to allow for some drying time before attempting to run your Frigidaire dishwasher.
