Whirlpool Washer Error Code F35

The F35 code indicates a steamer communication failure between the Central Control Unit and the steamer electronic board. The CCU is either not receiving a response from the steamer board, or the communication signal is corrupted. This fault prevents the steamer system from operating normally and requires diagnostic inspection of the wiring harness and control boards.

The F35 code specifically affects the steamer communication circuit, so standard wash cycles may still be possible depending on how the washer responds to the fault. However, running the appliance with an active fault code is not recommended, as the underlying wiring or board issue could affect other systems over time. It is best to diagnose and repair the issue before continued use.

Repair costs vary depending on which component is at fault. If the issue is simply a loose connector, there may be no parts cost involved, though a service call fee will apply if a technician is used. Replacing a steamer electronic board or CCU typically costs anywhere from $150 to $400 or more, including parts and labor, depending on your location and the specific parts required.

Start by checking the wiring harness connected to the steamer electronic board, looking for loose connectors or damaged wires. Reseat any connectors that are not fully engaged at both the steamer board and CCU ends. If the harness is intact, the steamer electronic board or CCU may need to be tested and potentially replaced.

A power reset may temporarily clear the F35 code, but the fault will return if the underlying communication problem has not been corrected. Unplugging the washer for a few minutes and restarting it can be useful for confirming whether the fault is intermittent, but it is not a repair. A lasting fix requires addressing the harness connection or faulty board causing the communication failure.
