LG Dishwasher Drain Pump Assembly Parts — Models & Compatibility

If your LG dishwasher won't drain or you're hearing grinding noises at the end of a cycle, there's a good chance the drain pump assembly has failed. This hub covers the AHA75693423 drain pump assembly — a direct replacement for LG part numbers EAU64082902, EAU64082901, AP6985799, and PS12750086. It fits over 50 different LG dishwasher models across multiple series including the W3S1CVK, F4V9RCP, and SWWE series.

Is This the Right Part for Your Model?

Check your dishwasher's model number before ordering. On most LG dishwashers, you'll find the model number on a label inside the door frame — open the door and look along the top or side edge. Your model number should match one of the compatible models listed below. Common series that use this pump include W3S1CVK2WVS, F4V9RCP2W, SWWE50N3, and SWWG50W4.

About This Replacement Drain Pump

The drain pump assembly is responsible for pumping water out of your dishwasher's tub at the end of each cycle. It's located at the bottom of the machine, usually accessible by removing the lower kickplate and tipping the dishwasher back slightly. This assembly includes the pump motor, housing, and impeller. When it fails, you'll typically see standing water at the bottom of the tub after a cycle completes, or you might hear the pump motor humming but not actually moving water. Some units will throw an OE error code indicating a drain issue.

What You're Getting

This is a complete drain pump assembly, not just the motor. You'll receive the pump housing, motor, impeller, and all necessary mounting hardware. It replaces LG factory part numbers EAU64082902 and EAU64082901, plus aftermarket equivalents AP6985799 and PS12750086. The assembly is designed to mount directly in place of your original pump using existing mounting points and hose connections.

Installation Overview

Replacing the drain pump typically requires disconnecting power, removing the lower access panel, disconnecting the drain hose and wire harness, and unbolting the old pump. You'll need basic hand tools and about 30-45 minutes. Some models require tipping the dishwasher back for easier access to the pump mounting bolts. Always disconnect power at the breaker before starting any repair work.
