Maytag Dishwasher Error Code F2

The F2 code on a Maytag dishwasher indicates a heater fault. The control board monitors the current running through the heater element and has detected that the current is not changing as expected during the heating cycle. This points to a problem with the heater element, the high limit thermostat, or the wiring connecting these components to the control board.

Running the dishwasher with an active F2 fault is not recommended. The heater fault means the appliance is not operating as intended, and dishes will likely not be properly cleaned or dried. Additionally, if a wiring issue is present, continued operation could pose an electrical risk. It is best to address the fault before resuming normal use.

Resetting the dishwasher may temporarily clear the F2 code, but it will return as soon as the control board runs the heating cycle and detects the same fault again. The underlying cause, whether it is a failed heater element, an open thermostat, or a wiring problem, must be identified and corrected to permanently resolve the error.

A knowledgeable DIYer with basic electrical skills can often diagnose and fix an F2 error. Start by inspecting the wiring harness to the heater for any loose or burned connections, then use a multimeter to test the heater element and high limit thermostat for continuity. Replacing a heater element or thermostat is a manageable repair, but if the control board is at fault, that replacement can be more complex.

Repair costs depend on which component has failed. A replacement heater element typically costs between $20 and $60 for the part, while a high limit thermostat is usually in the $10 to $30 range. If professional labor is involved, expect to add $100 to $200 in service fees. A control board replacement, if needed, is the most expensive repair and parts alone can range from $80 to $200 or more.
