Always verify compatibility using your appliance model number before ordering.

Restore powerful spray pressure, thoroughly cleaned dishes, and quiet operation to your kitchen routine with this Genuine OEM Frigidaire Dishwasher Wash Motor & Pump Assembly. This factory-certified, high-efficiency circulation module serves as the heart of your appliance’s cleaning system, driving pressurized water through the upper and lower spray arms to remove tough food soil.

Mounted directly to the underside of the main sump tub, this integrated motor and pump unit features a precision-molded internal impeller and a sealed heavy-duty drive motor. When activated by the main control board, it continuously draws filtered water from the sump basin, pressurizing it to force distribution through the spray arm nozzles. Designed for peak energy efficiency and long-term durability, it maintains ideal water volume and pressure throughout all wash cycles.

If this part fails, the internal impeller blades can wear out or become clogged with foreign debris, motor windings can short out, or the internal shaft seals can degrade. This leads to common failure symptoms, including dishes coming out dirty or gritty, spray arms that fail to rotate, a high-pitched buzzing, grinding, or humming noise coming from the bottom of the unit during wash cycles, or mid-cycle error codes (such as “i30” or circulation timeout warnings).

Quick Info

• Compatibility: Precision-engineered for modern Frigidaire, Electrolux, and Gallery series built-in dishwashers.

• Advanced Features: Heavy-duty motor housing, pre-installed high-pressure O-ring seals, green high-flow impeller assembly, and factory plug-and-play wiring harness connectors.

• Fixes Common Issues: Resolves poor cleaning performance, low spray arm water pressure, buzzing or humming noises during wash cycles, water not circulating while draining works fine, and mid-cycle wash timeouts.

• Difficulty: Intermediate. A straightforward DIY repair requiring a nut driver, standard pliers, and approximately 30 to 45 minutes.

💡 Critical Diagnosis & Prevention Tip

If your dishwasher fills completely with water and drains properly at the end of a cycle, but the dishes remain untouched and dirty, your drain pump is working, but your circulation pump motor (5304519906) has failed.

Before installing your new pump, thoroughly inspect the bottom of the sump basin and clear away any broken glass, seeds, or hard mineral buildup. Foreign objects dropping through damaged filter screens are the #1 cause of premature impeller blade lockups and motor failure!

Step-by-Step Replacement Guidelines

1. Safety & Power Isolation: Completely disconnect power to the dishwasher by turning off the dedicated breaker at your home’s main electrical circuit panel, and turn off the manual hot water shutoff valve underneath the sink.

2. Access the Lower Sump: Uninstall the lower front access kickplate panel by unthreading the mounting screws. Remove the bottom dish rack and filter assembly from inside the tub to gain clear visibility to the sump area.

3. Position & Unplug: Lean the dishwasher slightly forward or work through the lower front access panel. Disconnect the factory wiring harness plug from the motor housing.

4. Remove the Old Pump Assembly: Release the mounting locking tabs or bracket screws securing the pump assembly to the sump housing. Twist and pull the old motor unit out from its seating port, catching any small residual water with a towel.

5. Install the New Assembly: Ensure the new rubber O-ring seal is seated evenly on the new valve neck to prevent tub leaks. Push the new OEM pump into place until it seats firmly, secure the locking tabs/screws, plug in the wiring harness, reattach the kickplate, and restore power/water to run a quick test wash.
