Water remains standing in the tub after the cycle ends. A failed pump motor or clogged impeller prevents water from being expelled through the drain hose.
The control board detects the tub has not drained within the allotted time and displays an F9E1 fault. A defective drain pump is the primary cause of this error on Whirlpool and Maytag top-loaders.
A humming, buzzing, or grinding sound during the drain phase indicates the pump motor is seizing or the impeller is jammed with debris, requiring pump replacement.
If the washer appears to spin but clothes remain excessively wet, the pump is failing to remove residual water from the drum before or during the spin cycle.
The machine continuously attempts to drain without advancing to the spin or rinse cycle. This is caused by the control board repeatedly signaling a drain pump that is not functioning properly.
💡 Pro Tip: How to Confirm Your Drain Pump Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Washer displays F9E1 error code or gets stuck in the drain cycle
⚠️ Standing water remains in the tub after the cycle ends
⚠️ Loud buzzing, grinding, or humming noise during the drain phase
⚠️ Clothes come out soaking wet — drum spins but water won't expel
🔍 Diagnostic Tip: Set your multimeter to continuity mode and probe the drain pump motor terminals. No continuity = confirmed failed pump. Also check for 120V reaching the pump during the drain cycle — if voltage is present but the pump won't run, replacement is your only fix. Drain pumps are not repairable and must be replaced as a unit.
