Maytag Washer Error Code F43

F43 means the washer has detected that the heater element is on when the control system has told it to be off. This indicates a fault in the heating circuit, which could involve the control board relay, the heater element itself, or the wiring connecting them. The washer stops normal operation to prevent overheating or damage to your laundry.

No, continuing to run the washer with an F43 error is not recommended. A heater that stays on continuously can overheat the water, potentially damaging fabrics and internal components. The washer should remain out of service until the fault in the heating circuit is diagnosed and corrected.

A reset may temporarily clear the F43 code from the display, but it will not resolve the underlying electrical fault. If the heater relay is welded shut, the element is shorted, or the wiring is damaged, the fault condition still exists and the code will return as soon as the washer attempts a cycle involving the heater. Proper diagnosis and repair of the heating circuit are required to permanently clear this error.

A knowledgeable DIYer can perform the diagnostic steps outlined in the washer's TEST #9 procedure to identify the faulty component. Replacing a heater element or wiring harness is within reach for someone comfortable with appliance repair. However, if the control board relay is the source of the fault, board replacement or repair requires more advanced skills and comfort working with electronic components.

Repair costs vary depending on which component has failed. A replacement heater element typically runs in the range of $20 to $60 for the part, while a new or refurbished control board can range from $100 to $250 or more. Adding a technician's labor will increase the total, generally bringing a professional repair to somewhere between $150 and $400 depending on the specific fault and your location.
