Maytag Dishwasher Error Code 1F2

The 1F2 code means the high limit thermostat has detected a temperature above the safe threshold, either 155°F or 185°F depending on your model, and has shut off the heater element. This is a protective response to prevent overheating damage. The underlying cause could be a faulty thermostat, a defective heater element, or a control board issue that allowed temperatures to climb too high.

The 1F2 code itself represents the safety system working correctly, as the thermostat shut off the heater to prevent damage. However, the underlying cause of the overheating should be diagnosed and corrected before continuing to run the dishwasher. Repeated overheating events can damage the tub lining, door gasket, and other internal components over time.

Repair costs vary depending on which component has failed. A replacement high limit thermostat is generally an inexpensive part, with parts and labor typically ranging from around 80 to 180 dollars. If a heater element or control board is the root cause, costs can range from 150 to 400 dollars or more depending on labor rates in your area.

Start by checking the high limit thermostat for proper operation using a multimeter to test continuity at room temperature. If the thermostat has failed open, it will need to be replaced. Also inspect the heater element and verify the dishwasher is filling with an adequate amount of water, since a low water level can cause the heater to overheat quickly.

Resetting the dishwasher may temporarily clear the 1F2 code, but the error will return if the root cause has not been addressed. If the high limit thermostat has tripped due to a real overheating event, it may reset on its own after the unit cools down. A thermostat that has failed open will not allow the heater to operate regardless of resetting.
