Quick answer
If your washer isn't emptying water, first unplug it and check for clogs in the drain hose and pump. Clear any blockages and ensure the drain hose is properly installed. If the issue persists, test the pump and water level sensor.
Confirm the symptom
- Water remains in the drum after the cycle ends
- Washer stops mid-cycle with water still inside
- Drain pump makes gurgling or humming noises but no water flows out
- Error code related to drainage appears on the display
Tools and prep
- Screwdrivers (flathead and Phillips)
- Flashlight
- Bucket or towel to catch water
- Needle-nose pliers
- Work gloves
- Plumber's putty (for resealing hoses)
- Unplug the washer before starting work
- Turn off water supply to the washer
Step-by-step troubleshooting
- Check for Drain Hose ClogsDo: Locate the drain hose at the back of the washer and inspect for kinks or clogs.Observe: Water should flow freely when you lift the hose slightly.Means: A clogged or kinked hose prevents proper drainage.Next: Clear the clog or replace the hose if damaged.
- Inspect the Drain PumpDo: Access the drain pump (usually at the front or bottom of the washer) and remove any visible debris or lint.Observe: The pump should spin freely without resistance.Means: A clogged or faulty pump can't move water out of the drum.Next: If the pump is damaged or not working, replace it.
- Test the Water Level SensorDo: Check the water level sensor and its connections for damage or dirt.Observe: The sensor should show continuity when tested with a multimeter.Means: A faulty sensor can prevent the washer from recognizing when water needs to be drained.Next: Replace the sensor if it's damaged or not functioning.
- Verify Drain Hose InstallationDo: Ensure the drain hose is securely connected to the standpipe and not too high or too low.Observe: The hose should have a gentle downward slope toward the drain.Means: Improper installation can cause water to back up or drain slowly.Next: Adjust the hose height or reseal the connection if necessary.
- Check for Error CodesDo: Consult your washer's manual to interpret any displayed error codes related to drainage.Observe: Error codes can point to specific issues like pump failure or water level problems.Means: Error codes provide targeted guidance for troubleshooting.Next: Address the issue indicated by the error code.
- Test the Washer's Drain CycleDo: Run a drain-only cycle or manually drain water using a bucket or siphon.Observe: Water should drain completely if the issue is resolved.Means: This confirms whether the problem has been fixed or requires further action.Next: If water still doesn't drain, consider professional repair.
- Inspect the Lid SwitchDo: Check the lid switch for damage or wear, ensuring it's properly engaged when the lid is closed.Observe: The washer should start and run normally with the lid closed.Means: A faulty lid switch can prevent the washer from completing the drain cycle.Next: Replace the lid switch if it's damaged or not functioning.
- Check the Timer or Control BoardDo: Inspect the timer or control board for signs of damage or malfunction.Observe: The washer should progress through cycles correctly without stopping.Means: A faulty timer or control board can interrupt the drainage process.Next: Replace the timer or control board if necessary.

FAQ
Why is my washer not emptying water even though the pump is running?
The pump may be clogged with debris or the drain hose could be blocked. Check both for obstructions and clear them if necessary.
Can a faulty water level sensor cause drainage issues?
Yes, a malfunctioning water level sensor can prevent the washer from recognizing when water needs to be drained. Test the sensor and replace it if needed.
What should I do if the drain hose is too high?
Lower the hose so it has a gentle downward slope toward the drain. The hose should not be higher than 90 inches above the floor.
How can I tell if the drain pump is clogged?
If the pump is making gurgling or humming noises but no water is flowing out, it's likely clogged. Remove the pump and clear any debris or lint.
Is it normal for the washer to leave a small amount of water in the drum?
A small amount of water is normal after the cycle ends, but if there's a significant amount, there's likely an issue with the drainage system.
Can an overloaded washer cause drainage problems?
Yes, overloading the washer can block the drain pump or prevent the drum from spinning properly, leading to water remaining in the drum.
