Kenmore Washer Error Code OF

OF stands for overflow error on a Kenmore washer. It means the control board detected a water level frequency reading above 213, indicating the water inside the drum has exceeded the safe limit. The washer will automatically activate the drain pump to remove the excess water. The most common causes are a blocked air chamber tube or a water inlet valve that is not closing properly.

You should not run a wash cycle while the OF error is active, as the overflow condition means water levels are not being controlled correctly and flooding could occur. The washer will run the drain pump automatically to remove excess water, but you should investigate and resolve the underlying cause before starting another cycle. Continuing to use the machine with a stuck-open inlet valve risks water damage to your laundry room.

If the fix is simply cleaning the air chamber tube, the repair costs nothing beyond your time. Replacing a water inlet valve typically runs between 25 and 80 dollars for the part, with additional labor costs if you hire a technician. A faulty pressure sensor is generally in a similar price range, while a control board replacement can cost significantly more, typically between 100 and 250 dollars or higher depending on the model.

Start by unplugging the washer and locating the air chamber and its connecting tube, then clear any debris, kinks, or soap buildup you find. Next, with the washer still unplugged, check whether water continues to flow into the tub; if it does, the inlet valve is stuck open and needs replacement. If the tube is clear and the valve stops water correctly when unplugged, the pressure sensor may be faulty and should be tested or replaced.

A reset may temporarily clear the OF code from the display, but if the root cause is not corrected, the error will return as soon as the washer begins filling again. A failed inlet valve or a blocked pressure tube will continue to trigger the overflow condition on every cycle. Clearing the underlying fault is necessary before the error will stay resolved.
