A Cove dishwasher that leaves dishes dirty usually has clogged spray arms, a dirty filter, or weak circulation. The water is not reaching the dishes with enough force to clean them.
The fix is to clean the spray arms and filter and test the circulation pump pressure, replacing the pump if it is not delivering full flow.
Symptom and Error Guide
| Code / Symptom | What It Means | What We Do |
|---|---|---|
Dishes dirty | Clogged spray arms or filter | Clean the arms and filter |
Weak wash | Circulation pump not at full pressure | Test and replace the pump if needed |
Spray arms not turning | Blocked jets or bearing | Clear the jets, service the arm |
What We Check
- Cycle that stalls partway and will not finish
- Standing water left in the tub after a cycle
- Dishes not coming clean or spray arms not turning
- Door that will not latch or leaks at the seal
Regularly cleaning the filter and spray-arm jets keeps a Cove cleaning at its best. Hard-water scale can also block the jets over time, especially on well water.
