Understanding the Problem
If your WM2801HLA washer is not draining, leaving water in the tub, making a loud humming or grinding noise during drain, or leaking from the bottom, the drain (water) pump is a common failure point. The pump moves wash water out through the drain hose; when its impeller is jammed, the motor windings fail, or seals leak, the washer won’t evacuate water properly and can overflow or throw error codes related to drain faults. Before replacing the pump, inspect for clogs in the drain hose and pump inlet, check for foreign objects (coins, hairpins) that can jam the impeller, and listen during a drain cycle for a distinct motor hum or grinding. If clearing blockages doesn’t restore draining and the pump fails a continuity test or still hums without turning, replacement of the pump assembly is usually required.
Common Symptoms
Washer won’t drain or spins with water still in tub, loud humming or grinding noises during drain, water leaking from the bottom of the washer, and drain-related error codes.
Common Causes
- Failed pump motor (electrical failure or burned windings)
- Impeller jammed by debris (coins, small objects, fabric), or broken impeller
- Worn/cracked pump seals or housing causing leaks, or clogged/ kinked drain hose

Helpful Repair Tip
Run a drain-only cycle with the washer empty and listen at the base of the machine. A working pump will produce a smooth whirring sound and move water; a bad pump will either be silent, only hum, or produce grinding/squealing. Use a multimeter to check for motor continuity and inspect the impeller for obstructions before buying a replacement.
Frequently Asked Questions
How can I be sure the drain pump is the problem?
First, remove and inspect the pump inlet and drain hose for debris and clear any blockages. Run a drain-only cycle and listen: a humming sound with no water movement usually indicates a seized or failed pump motor. Use a multimeter to test the pump motor terminals for continuity (consult service manual for expected ohms). If the impeller is damaged, the motor has no continuity, or the pump leaks, replacement is required.
Can I replace the water pump myself and how long does it take?
Yes — a homeowner with basic tools can usually replace the pump. Typical time is 30–90 minutes depending on access and your experience. Always unplug the washer and turn off the water before beginning, drain any remaining water from the tub and hoses, and take photos of hose and wire connections to ensure correct reassembly. If the washer is hardwired or in a stacked/packed location, consider professional help.
