What this code means
The dishwasher did not complete drainage normally or detected abnormal drain-pump operation.
Most likely causes
- A kinked drain hose or incorrect high-loop/air-gap installation
- A blocked sink disposal connection, air gap, filter or pump area
- A failed drain pump
- An inverter, wiring or main-control problem on applicable models
Safe checks for the owner
- Clean the dishwasher filter if the model provides owner access.
- Inspect the drain hose, air gap and disposal inlet under the sink.
- If a disposal was recently installed, confirm its knockout plug was removed.
Estimated U.S. repair cost
$230–$480, depending on model, access, parts availability and local labor.
