What this code means
The control has detected an electrical problem in the drain-pump circuit or motor winding.
Most likely causes
- A failed drain-pump motor or winding
- A loose or damaged drain-pump connector
- A broken harness between the pump and power module
- A power-module fault affecting the pump circuit
Safe checks for the owner
- Disconnect power and check for standing water before opening the dishwasher.
- Clean the filter and visible pump area so a blockage is not mistaken for an electrical failure.
- Do not continue running the dishwasher if the pump is silent, overheats or trips the breaker.
Estimated U.S. repair cost
$260–$550, depending on model, access, parts availability and local labor.
