Kenmore Washer Error Code F5

The F5 error code on a Kenmore washer indicates one of three control system issues: the pump driver circuit has failed to activate, a main relay on the Central Control Unit is not working properly, or there is a communication error between the CCU and its onboard EEPROM memory chip. All three conditions originate within the CCU and its associated circuitry. The washer halts the cycle when this fault is detected.

You should not continue running the washer while the F5 error is active. A failed pump driver or relay means the washer may not drain properly, and continuing to operate it could leave standing water in the drum. A CCU with a communication fault can also behave unpredictably. Addressing the error before running additional cycles is the safest approach.

A reset may temporarily clear the F5 error, but if the underlying fault is still present, the code will return once the washer attempts to run a cycle. To reset, unplug the washer for several minutes and then restore power. If the error reappears immediately or returns during the next cycle, proceed with a full diagnosis of the power supply, wiring harness, and CCU rather than continuing to reset the machine.

Start by checking the simplest causes first. Confirm the washer is plugged into a dedicated circuit and that the outlet connection is tight and secure. Inspect the wiring harness connectors between the control board and the drain pump for loose pins or corrosion. If these checks do not resolve the error, the CCU itself likely needs replacement, which is a more involved repair but is manageable for experienced DIYers with the correct part.

Repair costs depend on the root cause. If the issue is simply a loose outlet or wiring harness connection, there may be no parts cost at all. If the CCU needs replacement, parts alone typically range from $100 to $300 depending on the specific model, with professional labor adding another $75 to $200. Diagnosing the exact cause before ordering parts is recommended to avoid unnecessary expense.
