Maytag Washer Error Code F36

F36 means the washer has detected a communication failure between the Central Control Unit (CCU) and the User Interface (UI) board. These two components must maintain a continuous data link for the washer to operate. When that link breaks down, the machine stops and logs F36. The fault can stem from loose connectors, damaged wiring, or a failed control board.

No, the washer is designed to stop operation when F36 is active because the control systems can no longer communicate reliably. Running the washer in this state could lead to unpredictable behavior during a cycle. It is best to diagnose and resolve the fault before resuming use.

Repair costs vary depending on the cause. If the fix is simply reseating a connector, there may be no parts cost at all, though a service call fee can range from $75 to $150. Replacing a UI board typically costs between $100 and $250 for the part, while a CCU replacement can range from $150 to $350 or more depending on the model, plus any applicable labor charges.

In some cases, yes. Start by unplugging the washer and inspecting the wiring harness connectors between the CCU and the UI board for loose, corroded, or damaged connections. Reseating a loose connector sometimes resolves the issue without any parts. If the wiring checks out, board replacement typically requires a technician with the right diagnostic tools.

A power reset by unplugging the washer for a few minutes may temporarily clear the code, but if the underlying cause is not fixed, F36 will return during the next cycle. A reset is useful for confirming whether the fault is intermittent, but it is not a repair. Follow the Test #10 diagnostic procedure to properly isolate the cause.
