What this code means
The control is receiving a water-level or pressure-sensor signal that is outside its expected range. On affected models the drain pump may run as a protective response.
Most likely causes
- A pressure hose has come loose, developed a leak or become blocked with residue
- The water-level sensor is electrically out of range
- A connector or wire between the sensor and main board is damaged
- The main control input circuit has failed
Safe checks for the owner
- Turn off the washer and water supply if it continues filling or draining unexpectedly.
- Do not blow into or alter the pressure hose without model-specific instructions.
- Power the washer off for several minutes and retry only if there is no active leak or uncontrolled filling.
Estimated U.S. repair cost
$210–$420, depending on model, access, parts availability and local labor.
