Possible Causes
How to Fix / Troubleshooting
Safety first: Disconnect power and close the water supply before accessing the base.
Steps:
- Confirm symptom: During wash, you hear only filling and occasional clicking, but no strong spray noise inside.
- Check for obstructions: Remove filters and inspect the sump for debris that could jam the pump impeller.
- Access pump: Remove the base panel, locate the circulation pump, and inspect for leaks or damage. Try rotating the impeller by hand (with power off); it should turn smoothly.
When to call a technician: If the pump is seized, noisy, or not receiving power, replacement or electrical diagnosis should be done by a professional.
