Step-by-step troubleshooting

Check Drain Hose
Do: Locate the drain hose at the back of the washer and inspect for kinks or clogs.
Observe: Water flows freely through the hose when you lift it.
Means: Hose is clear. Check other components.
Next: Check Pump Filter
Check Pump Filter
Do: Access the pump filter (usually at the front or bottom of the washer) and clean out any debris.
Observe: Filter is clean and free of lint, hair, or objects.
Means: Clog was in the filter. Washer may drain now.
Next: Test Washer
Inspect Pump
Do: Check the pump for visible damage or blockages. Use a multimeter to test for continuity.
Observe: Pump spins freely and shows continuity on the multimeter.
Means: Pump is working. Check for other issues.
Next: Check Drain Line
Check Drain Line
Do: Inspect the drain line from the washer to the home's plumbing for clogs or improper slope.
Observe: Drain line is clear and slopes downward toward the drain.
Means: Drain line is clear. Check for other issues.
Next: Test Washer
Test Washer
Do: Plug in the washer and run a drain cycle to see if water drains properly.
Observe: Water drains completely from the drum.
Means: Issue resolved. Washer is functioning properly.
Next: Done
Check Lid Switch
Do: Ensure the lid switch is working correctly, as a faulty switch can prevent the washer from draining.
Observe: Lid switch clicks when the lid is closed and the machine runs.
Means: Lid switch is working. Check for other issues.
Next: Check Control Board

FAQ

How often should I clean the pump filter?

Clean the pump filter every 3–6 months to prevent clogs and maintain proper drainage.

Can a clogged drain hose cause the washer to stop mid-cycle?

Yes, a clogged drain hose can cause the washer to pause or stop during the drain cycle to prevent overflow.

Is it normal for the pump to make noise during drainage?

Some noise is normal, but loud or unusual noises may indicate a clog or a failing pump.

Can a faulty water inlet valve affect drainage?

No, the water inlet valve affects water intake, not drainage. Drain issues are usually related to the pump, filter, or drain hose.
