Kenmore Washer Error Code F/27

F/27 indicates an overflow condition, meaning the overflow contact on the pressure switch stayed closed for more than 60 seconds. The washer interprets this as the water level reaching a dangerous height and stops the cycle to prevent flooding. This fault is most commonly caused by a restricted drain hose or a faulty pressure switch.

It is not recommended to continue using the washer while this error is present. The F/27 code exists to protect against overflow and potential water damage to your home. Running the machine without resolving the root cause could result in water escaping the tub and damaging flooring, cabinetry, or the washer itself.

Repair costs vary depending on the cause. If the issue is only a kinked or improperly routed drain hose, there may be no parts cost at all. Replacing a pressure switch typically runs between $20 and $60 for the part, while a water inlet valve generally costs between $25 and $75 for the part. Adding professional labor will increase the total, usually ranging from $100 to $200 or more depending on your location and the technician's rates.

Start by checking the drain hose for kinks, clogs, or a too-tight connection at the standpipe. If the drain path is clear, inspect the pressure switch air hose for cracks or blockages and test the pressure switch itself for proper operation. Also check whether the water inlet valve is shutting off completely after the fill cycle. Addressing the underlying cause is necessary before the error will stay cleared.

A reset may temporarily clear the error code and allow the cycle to resume, but if the underlying problem is not fixed the fault will return. Simply resetting the washer without addressing the drain hose, pressure switch, or inlet valve is only a short-term workaround. Proper diagnosis and repair of the root cause is required for a lasting fix.
