Loading, Filters, and Results
Cove cleans very well when the spray arms can reach every surface, so the first thing to check when results slip is the load. Give tall items room, keep the arms free to spin, and confirm the filter under the lower rack is clean. On Castle Rock water, spotting on glassware is usually mineral scale rather than a fault; a filled rinse-aid reservoir and a monthly clean cycle with a dishwasher descaler make a real difference. Verify the small jets in the spray arms are not plugged with food debris or scale.
Drainage and Start-Up
If clean water sits in the sump after a cycle, remove and rinse the filter, then clear the drain hose of any kink and confirm the disposer knockout is open. Run a short cycle and watch it pump out. For a Cove that will not start, the door has to be latched fully and the control lock off. A wet fingertip on the touch panel or a delay-start left on can also stop the cycle from beginning.
| Symptom | Try First | If It Continues |
|---|---|---|
| Spots on glassware | Fill rinse aid, run clean cycle | Water hardness treatment |
| Standing water | Clean filter, clear drain hose | Drain pump service |
| Cycle will not start | Latch door, check control lock | Latch switch service |
| Not drying | Add rinse aid, allow auto-open | Heating circuit test |
| Odor in tub | Clean filter and spray arms | Sump and check-valve service |
Where to Stop
Do not pull the drain hose off the disposer while the tub is full, do not open the pump housing, and do not force a stuck door latch. If water reaches the floor, close the supply valve under the sink and book service. Cleaning parts you can reach by hand is as far as safe DIY goes on a Cove.
