Clear the Filter and Sump First
Standing water at the end of a cycle points straight to the filter. Food debris clogs the filter and sump and slows or stops drainage. Remove the filter, rinse it thoroughly, and clear the sump area underneath. This alone fixes a large share of no-drain complaints.
| Check | Common Finding | Action |
|---|---|---|
| Filter and sump | Food debris | Clean and rinse |
| Drain hose | Kink or clog | Straighten, clear |
| Air gap | Grease buildup | Clean fitting |
| Drain pump | Jammed impeller | Clear or replace |
Check the Drain Hose and Air Gap
Trace the drain hose to the sink and look for kinks behind the cabinet or a blockage at the disposer or air gap connection. Sink air gaps collect grease and debris and are an easily missed cause of poor drainage. Unclip and clean the air gap fitting if your installation has one.
The Disposer Connection
If the Cove drains into a garbage disposer, a knockout plug left in the disposer inlet, or food packed into it, blocks drainage entirely. Running and clearing the disposer often restores flow. A slow or backed-up sink drain causes the same standing water.
Testing the Drain Pump
If the filter, hose, air gap and disposer are all clear, the drain pump may be jammed by a shard of glass or debris in the impeller, or failing electrically. Because Cove reports through lights rather than a code, a technician confirms the pump by testing it directly and clears or replaces it as needed.

Frequently Asked Questions
Why Is My Cove Dishwasher Not Draining?
Usually a blockage: a clogged filter, a kinked or blocked drain hose, a dirty air gap, or a plugged disposer inlet. Clearing the drain path resolves most cases before the pump is ever the problem.
How Do I Clear Standing Water from a Cove Dishwasher?
Remove the standing water, then clean the filter and sump, check the drain hose for kinks, and clear the air gap or disposer. Run a short cycle to confirm it drains.
Could a Cove Drain Pump Be the Problem?
It can, if all the drain-path checks are clear. A pump jammed by debris or failing electrically will leave standing water. A technician tests the pump directly since Cove has no numeric code to read.
