Step-by-step troubleshooting
Check Drain Hose
Do: Locate the drain hose at the back of the washer and inspect for kinks or blockages.
Observe: Look for visible clogs or bends in the hose.
Means: A kinked or clogged hose prevents proper drainage.
Next: If a clog is found, proceed to clear it. If not, move to the next step.
Clear Drain Hose Clog
Do: Use a plunger to push water and debris through the hose. If ineffective, use a drain snake.
Observe: Water should flow freely through the hose after clearing.
Means: A clear hose allows water to drain properly.
Next: If the hose is clear, move to the next step. If not, consider replacing the hose.
Inspect Pump Filter
Do: Locate the pump filter (usually at the front or bottom of the washer) and remove it using a screwdriver.
Observe: Check for debris, lint, or foreign objects in the filter.
Means: A clogged filter restricts water flow.
Next: Clean the filter and reinstall it. If the issue remains, move to the next step.
Check Drain Pump
Do: Access the drain pump by removing the front or lower panel. Inspect the pump for damage or blockages.
Observe: Look for broken parts or large debris stuck in the pump.
Means: A damaged or clogged pump cannot drain water effectively.
Next: If the pump is damaged, replace it. If not, move to the next step.
Verify Drain Line Clearance
Do: Ensure the drain line is not connected to a garbage disposal and is at least 4 inches below the floor drain.
Observe: The drain line should slope downward and not be pinched.
Means: Improper installation can cause drainage issues.
Next: Adjust the drain line if necessary. If the problem persists, move to the next step.
Test Washer Functionality
Do: Run a test cycle with the washer empty to see if water drains completely.
Observe: The washer should drain fully without remaining water.
Means: Successful drainage indicates the issue is resolved.
Next: If the washer drains properly, the issue is resolved. If not, consider professional help.
