Kenmore Washer Error Code ob

The ob code means the motor controller detected an off-balance condition severe enough that it could not recover on its own and stopped the spin cycle. The machine requires the user to open the lid at least once, which resets the motor controller's fault state, before it will allow the cycle to restart. This is a built-in protection to prevent damage from extreme drum vibration.

Pressing STOP/CANCEL will clear the ob code from the display, but the motor controller requires that the lid be physically opened at least once before it will allow the machine to restart a spin cycle. Simply unplugging the machine and plugging it back in without opening the lid may not fully complete the reset sequence required for this specific fault.

If the ob error is caused by worn suspension rods or springs rather than a simple load issue, the cost of parts is typically in the range of $15 to $60 depending on the number of rods and the specific model. If a technician is hired for the repair, total costs including labor generally range from $80 to $200. Redistributing an uneven load costs nothing and should always be tried first.

Start by pressing STOP/CANCEL or opening the lid to clear the display. Then open the lid, reach in, and manually redistribute the laundry so it is spread evenly around the drum. Close the lid and restart the cycle. If the error returns repeatedly, check for worn suspension rods or springs, and avoid washing single heavy items without adding a balancing item.

The ob code is actually a safety feature, as the machine has already stopped itself to prevent damage. Running a washer with a severe off-balance load can stress the drum bearings, suspension system, and cabinet over time. Always redistribute the load and address any underlying suspension issues before continuing to use the machine regularly.
