Whirlpool Washer Not Draining? Drain Pump WPW10276397 – Fix Standing Water Fast
A washing machine that won’t drain, leaves standing water in the drum, or stops mid-cycle is almost always a failed drain pump — not a control board or lid switch issue. In most Whirlpool, Maytag, Amana, and Inglis top-load washers, this is caused by a failed drain pump assembly. When it fails, water cannot be expelled from the drum, the washer stops mid-cycle, and error codes like F21 or Sud appear on the display. ⚡ One of the highest-volume washer repairs across the entire Whirlpool platform — this pump fails on hundreds of models. Part WPW10276397 is the genuine OEM replacement that restores full drain function and clears standing water immediately.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Washer powers on and agitates normally — only the drain cycle fails
- ✔ The lid latch and door switch are confirmed functioning
- ✔ No foreign objects (coins, socks) are blocking the pump filter or drain hose
- ✔ The drain hose is not kinked, clogged, or improperly routed
- ✔ ONLY problem is water remaining in the drum after the cycle ends
🔧 Common Symptoms
- Washer stops mid-cycle with water still in the drum
- F21, F9E1, or Sud error code displayed
- Washer runs but never drains — drum stays full
- Loud humming or grinding noise during the drain cycle
- Washer takes much longer than normal to complete a cycle
- Water leaking from under the washer near the pump housing
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this drain pump restores normal drain function immediately.

⚙️ Installation Notes
Skill Level: Moderate — 30–45 minutes. Disconnect power and water supply before servicing. Tilt the washer back or lay it on its side to access the pump from the bottom, disconnect the wiring harness and two drain hoses from the old pump, remove the mounting screws, install the new WPW10276397 pump, reconnect hoses and harness, and restore power to test. Have towels ready — residual water will drain when hoses are disconnected.
💡 Pro Tip
Check the Pump Filter First:
Before replacing the pump, remove and clean the pump filter — a sock, coin, or debris buildup is the #1 cause of drain pump failure on this platform. If the filter is clear and the pump hums but doesn’t move water, the pump impeller has failed and WPW10276397 is your fix. Skipping the filter check is the most common reason customers replace a pump that didn’t need replacing.
