LG Dishwasher Drain Pump ABQ73503004

This genuine LG Electronics drain pump assembly replaces a failed or noisy pump in compatible LG dishwashers. It restores proper water drainage during the wash and rinse cycles. The part is supplied new and carries the original manufacturer part number ABQ73503004. It is intended for owners and technicians servicing LG dishwashers.

Replaces worn or failed original drain pump

Install this assembly when the existing pump no longer evacuates water, makes unusual grinding sounds, or triggers a drainage error code. The upgrade is worth it when troubleshooting confirms the pump motor or impeller is the root cause rather than a simple blockage. It returns the appliance to factory drainage performance without modifying the plumbing.

Direct-fit installation for qualified repair

The pump assembly mounts in the original location using the factory fasteners and connects to the existing wiring harness and hose fittings. No wiring changes or bracket fabrication are required. Common issues include forgetting to clear debris from the sump before fitting the new unit and over-tightening the hose clamps, which can crack the pump housing.

Questions about this item

Will the ABQ73503004 drain pump assembly fit my specific LG dishwasher model?

This is an OEM LG part numbered ABQ73503004 designed for compatible LG dishwashers; verify your appliance model number against the manufacturer parts list before ordering.

How is the drain pump assembly installed and what step is commonly missed?

Installation requires disconnecting power and water, removing the lower access panel, detaching the old pump wiring and hoses, then securing the new assembly; the step often missed is properly reseating and clamping the drain hose to prevent leaks.

What maintenance or replacement will this drain pump need over time?

The pump itself has no user-serviceable filter; long-term care involves periodically cleaning the dishwasher's separate filter assembly to prevent debris from damaging the impeller, and replacing the pump if the motor fails or the housing cracks.
