Maytag Dishwasher Error Code F7-E2

F7-E2 means the dishwasher has detected that the heating element is stuck on because the heater relay on the control board has failed in the closed position. The relay is unable to cut power to the heater as commanded, so the board flags the fault. You should disconnect power to the dishwasher right away and have the control board and heater components inspected.

No, you should not continue using the dishwasher while F7-E2 is active. A heater that cannot be turned off can overheat internal components and potentially cause further damage or a fire hazard. Disconnect power to the unit until the control board and heater components have been inspected and the faulty parts replaced.

Repair costs vary depending on which components need replacement. A new control board typically ranges from $100 to $250 for the part alone, and a heater element generally falls between $20 and $80. Adding professional labor, total repair costs commonly range from $150 to $400 depending on your location and the extent of any heat damage to wiring or other components.

A knowledgeable DIYer can address this repair, but it does require working with electrical components and visually inspecting for heat or fire damage. The repair involves disconnecting power, inspecting the heater and wiring for signs of shorting or overheating, and replacing the control board. If there is visible burning or melted wiring, a professional technician should assess the damage before any parts are replaced.

A power reset may temporarily clear the displayed code, but it will not fix the underlying hardware fault. If the heater relay on the control board has failed closed, the fault condition remains regardless of any reset. The code will return and the heater will continue to operate without proper control until the defective control board or heater components are replaced.
