Understanding the Problem
When a washer fills but won't remove the water at the end of the cycle, the most common culprit is the drain system. That includes the drain pump, the drain hose or trap (coin filter), and sometimes the lid/door switch or control board that tells the pump to run. A blocked hose or trap can prevent water flow even if the pump motor is fine. Conversely, a failed pump motor can stop turning or only hum without moving water. Front-load and high-efficiency top-load washers also use door lock assemblies and pressure/level sensors that impact the drain and spin cycles. If a door lock or pressure switch fails, the washer may not start the drain or spin step. Diagnosing the problem requires checking for visible obstructions, listening for the pump during a drain cycle, and testing electrical components if the pump doesn't run.
Common Symptoms
Washer fills but won't drain or spin; water remains in the tub; washer shows drain-related error codes; pump hums but doesn't move water; persistent standing water after cycle.
Common Causes
- Clogged drain hose, pump filter or coin trap preventing water flow
- Failed drain pump motor or pump impeller damage
- Faulty lid/door switch or door lock preventing the pump from receiving power
- Blocked or kinked drain line to household plumbing
- Malfunctioning control board/timer or pressure/level sensor

Helpful Repair Tip
Start a drain/spin cycle and watch/hear the pump. If you hear a humming but no water moves, check the pump filter/coin trap and drain hose for blockages before replacing the pump. Use a multimeter to check pump motor continuity and verify voltage at the pump during a drain cycle to confirm an electrical failure.
Frequently Asked Questions
How can I test whether the drain pump is bad?
Begin by running a drain/spin cycle and listen: if the pump doesn't run and there's no humming, the pump may not be receiving power or is dead. First disconnect power and check the pump and hose for visible obstructions. With power off, remove the pump filter/coin trap and clear debris. Test the pump motor for continuity with a multimeter (expect some low ohms; open circuit indicates a failed motor). If safe and you know what you're doing, restore power and check for voltage at the pump during a drain cycle — absence of voltage points to a door switch or control problem; correct voltage but no motor rotation indicates a bad pump needing replacement.
Can I drain the washer myself so I can finish a load?
Yes — you can manually drain most washers. For front-load and many top-load machines there is a small drain hose or pump filter access at the base; remove the cap and let water flow into a shallow pan or use a hose to direct it to a floor drain. Alternatively, use a bucket to bail out water. Avoid running a spin cycle with large amounts of water removed unevenly — rebalance the load first. If you're uncomfortable, call a technician to avoid damage or injury.
