Washer Not Draining? Drain Pump WPW10391443 – Fix Standing Water Fast
When your Whirlpool, Maytag, or Amana front-load washer won't drain and water is left standing in the drum, the drain pump is the most common failed component. In most Whirlpool-platform front-load washers, the drain pump is responsible for evacuating all water at the end of each cycle — when it fails, the washer stops mid-cycle, triggers a drain error code, or leaves clothes soaking wet. ⚡ One of the highest-failure wear parts in Whirlpool-built front-load washers. Part WPW10391443 is the genuine OEM replacement that restores full drain performance with a direct factory fit — supersedes W10391443 with no modification required.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Washer powers on and fills with water normally
- ✔ Wash and rinse cycles run but water remains in drum
- ✔ Drain hose is not kinked, blocked, or improperly routed
- ✔ Pump filter/coin trap has been cleaned and is not clogged
- ✔ ONLY problem is water not draining or F21/F9E1 drain error code

📦 Part Details
- Part Number: WPW10391443
- Type: Washer drain pump assembly — front-load platform
- Replaces: OEM direct-fit drain pump — supersedes W10391443 (no modification required)
- Brands: Whirlpool, Maytag, Amana
Inspect the door boot seal and pump filter housing while the pump is out — foreign objects (coins, debris) that killed the original pump are often still present in the filter housing and will damage the new pump if not removed. Clean the filter and check the boot seal for tears before reinstalling.
⚙️ Installation
Skill Level: MODERATE — 30–45 minutes. Disconnect power at the breaker before beginning. Access the pump from the front lower panel or by tilting the washer back depending on model — drain any remaining water first using the pump filter access port. Disconnect the wire harness and hose clamps, swap in the new pump, reconnect all connections, and restore power. Run a drain/spin cycle to confirm full drainage before closing up the panel.

💡 Pro Tip
Before ordering a new drain pump, locate the small access door on the lower front of your washer and clean the pump filter — a sock, coin, or debris buildup here is the #1 cause of drain failures and costs nothing to fix. If cleaning the filter doesn't resolve the F21/F9E1 error or standing water, the pump itself has failed and WPW10391443 is the correct replacement.
