Understanding the Problem
When a washer is not pumping water out, the tub remains full at the end of the cycle, clothes stay soaked, and many machines will display an error code or fail to advance to spin. The likely trouble spots are a clogged drain path (pump filter, hose, or trap), a failed drain pump motor, or an electrical/control issue that prevents the pump from getting power. Front-load and many high-efficiency top-load washers also have a removable pump filter or trap that often collects lint, coins, and debris and is the simplest cause to check first. Diagnosing the problem involves confirming whether the pump is being commanded to run and whether it can run freely. You can often hear the pump run (a humming or whirring) during drain, or you may hear nothing at all. In some cases the pump hums but doesn't move water because the impeller is jammed by debris or broken. Less common causes include a failed lid/door switch or a defective control board or timer that never sends power to the pump.
Common Symptoms
Washer stops mid-cycle with water in tub; error codes related to draining; loud grinding or humming from pump area; clothes extremely wet after cycle.
Common Causes
- Clogged pump filter, trap or drain hose (lint, coins, small clothing items)
- Failed drain pump motor or broken pump impeller
- Blocked or kinked external drain hose or house drain
- Faulty lid/door switch or control board not supplying power to the pump

Helpful Repair Tip
Run a drain/spin cycle while listening — if you hear a hum but no water moves, disconnect power and inspect the pump impeller/filter for jammed debris; if you hear nothing, test for voltage at the pump during a drain cycle to see if the control is sending power.
Frequently Asked Questions
How can I tell if the drain pump is actually bad?
First, run a drain/spin and listen: a working pump usually makes a distinct whirring or churning sound. If you hear a hum but no water moves, open the pump filter or access the pump and check for jammed debris or a broken impeller. If you hear nothing, use a multimeter to check pump motor continuity (no continuity can indicate a burned motor) and use a voltmeter to check whether the control board is sending ~120V (or model voltage) to the pump during drain — if there's voltage but the pump doesn't run, the pump is bad.
Can I fix a washer that won't pump myself, or do I need a technician?
You can often fix common causes yourself: cleaning the pump filter/trap, removing kinked or clogged hoses, and replacing an accessible pump are typical DIY jobs if you are comfortable unplugging the machine and removing panels. Always disconnect power and water before working. Call a technician if the problem involves testing or replacing the control board, complex motor mounts, sealed tub assemblies, or if you find electrical faults you are not trained to repair.
