Whirlpool Washer Drain Pump Parts — Models & Compatibility

When your Whirlpool washer won't drain or you notice water pooling at the bottom after a cycle, the drain pump is usually the culprit. This hub covers the W10276397 drain pump assembly — a direct replacement for multiple Whirlpool, Maytag, and Kenmore top-load washer models. Whether you've got a WTW4800 series or an older ATW4675, this is your starting point for finding the right drain pump.

Is This the Right Part for Your Model?

Before ordering, you'll need your washer's exact model number. On most Whirlpool top-load washers, you'll find this on a sticker inside the lid opening or along the back panel near the water inlet valves. Cross-reference your model number with the compatibility list below — if it matches, the W10276397 will fit.

About This Replacement Part

The W10276397 is a complete drain pump assembly that handles all the water evacuation during your washer's drain and spin cycles. The pump motor uses an impeller to push water through the drain hose and out of the tub. Over time, debris like coins, lint, or small fabric pieces can jam the impeller, or the motor itself can burn out from extended use. You'll know it's failing when water stays in the tub after a cycle completes, or you hear the pump trying to run but nothing drains. This assembly replaces part numbers WPW10276397, AP6018417, 1874334, and PS11751719 across multiple model series.

Common Failure Scenarios

The drain pump may become clogged, damaged, or defective, preventing the washer from draining. Typical symptoms include water remaining in the tub after the cycle, leaking water around the pump area, or a humming sound with no actual draining happening. If you've already checked for kinked drain hoses and cleared the pump filter but still have standing water, the pump motor has likely failed.

Installation Difficulty

Replacing the drain pump on these Whirlpool models is considered a moderate repair. You'll need to tip the washer back or remove the front panel to access the pump at the base of the tub. The pump connects with a few hose clamps and an electrical connector — no special tools beyond basic hand tools are required. Expect to spend 30-45 minutes on the swap if you're comfortable working with appliances.
