Quick answer
If your washer isn't putting out water, first check the drain hose for clogs and ensure the pump is running. Clear any blockages and restart the machine. If it still doesn't drain, inspect the pump filter or call a pro.
Confirm the symptom
- Washer fills with water but doesn't drain during cycle
- Water remains in the tub after spin cycle
- Washer makes gurgling or bubbling sounds during drain phase
- Error code related to drainage appears on display
Tools and prep
- Screwdrivers (flathead and Phillips)
- Adjustable wrench
- Bucket or towels to catch water
- Flashlight for inspection
- Replacement parts if needed (e.g., drain pump, filter)
- Turn off power at circuit breaker for safety
- Shut off water supply to prevent overflow
Step-by-step troubleshooting
- Check Drain HoseDo: Locate the drain hose at the back of the washer and inspect for kinks or clogs.Observe: Hose is clear and properly connected to the standpipe.Means: Hose is not the issue; move to next step.Next: Check Drain Pump
- Check Drain PumpDo: Listen for the pump motor during the drain cycle. Use a screwdriver to access the pump and look for blockages.Observe: Pump is running and free of debris.Means: Pump is working; check next component.Next: Inspect Pump Filter
- Inspect Pump FilterDo: Locate the pump filter (often near the front lower panel) and clean it according to the manual.Observe: Filter is clean and free of lint or debris.Means: Filter is clear; try running a cycle.Next: Test Washer
- Test WasherDo: Restart the washer and run a short cycle to see if water drains properly.Observe: Water drains completely during the cycle.Means: Issue resolved; no further action needed.Next: End
- Check Standpipe HeightDo: Measure the standpipe height to ensure it meets manufacturer guidelines (usually 30–40 inches).Observe: Standpipe height is within recommended range.Means: Standpipe is correctly installed.Next: Inspect Pump Impeller
- Inspect Pump ImpellerDo: Remove the drain pump and check the impeller for damage or blockage.Observe: Impeller spins freely and shows no signs of wear or debris.Means: Pump is functional; issue may be elsewhere.Next: Call a Professional
- Call a ProfessionalDo: If previous steps fail, contact a certified technician for diagnosis.Observe: Professional resolves the issue or identifies a major repair.Means: Problem is fixed or properly addressed.Next: End
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Clogged Drain Hose Debris or lint can block water flow from the washer. | Common | Easy | Drain Hose Cleaning |
| Clogged Drain Pump Filter Lint and debris accumulate in the filter, preventing proper drainage. | Common | Easy | Drain Pump Filter |
| Faulty Drain Pump The pump motor or impeller may fail, stopping water from draining. | Sometimes | Medium | Drain Pump |
| Incorrect Standpipe Installation Standpipe too low or high can cause drainage issues or siphoning. | Sometimes | Easy | Standpipe Adjustment |
| Blocked Pump Impeller Foreign objects or debris can jam the impeller, stopping the pump. | Sometimes | Medium | Drain Pump |
| Faulty Lid Switch or Door Lock Some washers won't drain if the lid or door isn't properly closed. | Rare | Medium | Lid Switch or Door Lock |
| Control Board Malfunction A faulty control board may fail to activate the drain pump. | Rare | Hard | Control Board |
Parts matching
If you need parts for your washer, match your model to the correct components:
- Drain Pump – Replaces a faulty pump that won't drain water
- Drain Pump Filter – Clears lint and debris from the pump system
- Standpipe Extension – Adjusts standpipe height to proper level
- Water Inlet Valve – Not directly related, but may be needed if water isn't filling properly
- Lid Switch/Door Lock – Ensures washer operates safely and drains correctly
Always check your washer's manual for specific part numbers and compatibility.
When to call a professional
- Water still doesn't drain after clearing all clogs and checking components
- Drain pump makes loud noises or fails to activate at all
- Washer displays persistent error codes despite troubleshooting
- You suspect internal electrical issues (e.g., control board failure)
- You're unsure about removing or replacing internal parts safely
FAQ
Can I use a plunger to unclog my washer's drain?
Yes, but only on the standpipe or drain hose. Never plunge inside the washer tub, as this can damage components.
How often should I clean the drain pump filter?
Every 3–6 months, or more frequently if you have hard water or frequent drainage issues.
Why does my washer drain slowly even after cleaning the filter?
A partially clogged hose, a worn pump impeller, or incorrect standpipe height could still be the cause.
Is a faulty drain pump expensive to replace?
Cost varies by model, but parts typically range from $50 to $150, plus labor if installed by a pro.
Can a bad water inlet valve cause drainage problems?
No, but it can prevent water from filling the washer. Drain issues are usually separate from inlet valve problems.
