Whirlpool Washer Error Code F81

F81 on a Whirlpool washer signals a lid switch or lid position fault. The code appears when START is pressed with the lid open, when two cycles run back to back without the lid being opened between them, or when the control board cannot properly detect the lid switch state. It is a safety interlock that prevents the washer from operating unless the lid status is confirmed.

A reset may temporarily clear the code, but it will return if the underlying cause is not addressed. If the fault is simply an open lid or the two-cycle sequence issue, opening and closing the lid before restarting may resolve it without a full reset. If the lid switch or wiring is defective, the error will reappear as soon as you attempt to start another cycle.

If the fix is simply opening and closing the lid, there is no cost. A replacement lid switch assembly typically costs between $15 and $60 for the part, depending on the specific model. If professional labor is needed, total repair costs including parts and service generally range from $80 to $200. Control board replacement, if required, can push costs higher.

Start by opening the lid fully, closing it firmly until it clicks, and pressing START again. If you ran two cycles in a row without opening the lid, that alone may clear the error. If the code returns, follow TEST #8 to check the lid switch for proper continuity and inspect the wiring harness for loose connectors or damaged wires. A failed lid switch will need to be replaced to resolve the fault.

The washer will not start a cycle while F81 is active, which is intentional. The lid switch is a safety component designed to prevent the tub and agitator from spinning with the lid open. Do not attempt to bypass the lid switch to force the machine to run, as this removes an important protection against injury.
