Maytag Washer Error Code F4E0

F4E0 means the Appliance Control Unit attempted to activate the heating element but did not detect any rise in water temperature in response. The control board monitors temperature feedback continuously during heated wash cycles, and this code triggers when that expected feedback is absent. The fault points to the heater element, its wiring connections, or the temperature sensor as the likely source of the problem.

Resetting the washer may temporarily clear the F4E0 code from the display, but the code will return if the underlying problem is not repaired. The ACU will re-trigger the fault as soon as it runs a heated cycle and again fails to detect a temperature rise. A proper repair to the heater element or temperature sensor is required to permanently resolve the error.

Repair costs vary depending on which component has failed. A replacement heating element typically costs somewhere in the range of $30 to $80 for the part alone, while a temperature sensor is generally less expensive. If professional labor is included, total repair costs commonly fall in the range of $100 to $250 depending on local rates and whether one or both components need replacement.

Some steps, such as checking the hot water supply temperature or visually inspecting whether the heater element connector has come loose, can be done without specialized tools. However, testing the heating element for continuity and evaluating the temperature sensor typically require a multimeter and some familiarity with appliance diagnostics. If you are not comfortable working with internal washer components, a qualified technician should perform TEST #9 and TEST #10 to pinpoint the fault.

The washer may continue to run cycles, but heated wash functions will not work correctly while this fault is active. There is no immediate safety hazard from a failed heater element or sensor, but running cycles without functional temperature control means laundry may not be washed at the intended temperature. It is best to address the fault before continuing regular use, especially for cycles that require sanitizing or specific temperature targets.
