What this code means
The washer could not distribute the load well enough to reach its target spin speed. Repeated errors with normal loads may indicate a leveling, suspension, sensor or motor issue.
Most likely causes
- A single heavy item, tiny load or mixed items with very different weights
- Laundry is tangled or concentrated on one side of the tub
- The washer is not level or the floor is flexing
- Worn suspension rods, shocks, bearings, hall sensor or motor components
Safe checks for the owner
- Pause the cycle and redistribute the load evenly.
- Add a few similar items to a very small load or remove items from an overloaded tub.
- Confirm that all feet contact a solid floor and the cabinet does not rock.
Estimated U.S. repair cost
$250–$520, depending on model, access, parts availability and local labor.
