For Cove owners seeing cove dishwasher not draining fix, the fault usually comes back to a blocked drain pump, clogged filter, or kinked drain hose. This article explains what to check, the diagnostic path we follow, and the genuine OEM parts involved.
Standing Water at the End
A Cove dishwasher that will not drain leaves water in the tub after the cycle. On the DW24 the usual causes are a clogged filter, debris in the sump or drain pump, a drain hose with a bad high loop, or a blocked air gap at the sink. Cove keeps the drain path conventional, so the fault is almost always a blockage rather than an electronic one.
Clearing the Path
We pull and clean the filter and sump, check the pump impeller for glass or debris, and confirm the hose routing and the air gap. Most Cove drain calls resolve with a thorough cleaning and a corrected hose. Where the drain pump has failed, a model-specific part goes in, and we test a full drain to confirm the tub empties cleanly before we finish.
| Symptom | Likely Cause | What We Check |
|---|---|---|
| Water left in tub | Filter, pump, or hose | Filter, sump, and drain path |
| Drains slowly | Partial restriction | Hose loop and air gap |
