Kenmore Dishwasher F15 Error Code — Drain Pump Fault

Kenmore Dishwasher F15 Error — Drain Pump Failure

The F15 error code indicates the drain pump is not operating correctly, leaving standing water in the dishwasher tub at the end of a cycle. This is one of the more commonly reported Kenmore dishwasher errors and is usually caused by a clogged or failed drain pump.

Common Causes

• Broken glass, food debris, or a twist-tie blocking the drain pump impeller
• Failed drain pump motor (no humming sound when drain cycle starts)
• Kinked or blocked drain hose
• Clogged air gap or garbage disposal connection

Troubleshooting Checklist

1. Check for visible standing water and remove with towels or a wet vac.
2. Remove and clean the filter and sump area thoroughly.
3. Inspect the drain pump for debris — remove the pump cover and check the impeller.
4. Verify the drain hose is not kinked behind the dishwasher.
5. Check the air gap (countertop fitting) and garbage disposal connection for blockages.

Professional Repair

If the drain pump motor has failed (confirmed by testing for continuity and finding an open circuit), a replacement pump is needed. This is a straightforward repair for our technicians and is typically completed during the initial service call.
