Washer displays F15, may not heat water properly or may stop during a heated cycle.

Safety first: Unplug the washer and shut off water supply. Heating circuits operate at line voltage; use caution.

Step-by-step:

• Confirm model has heater: Not all Maytag washers have internal heaters. Check your model number and manual.
• Access heater: On many front-loaders, the heater is located at the bottom front of the tub, accessible from the rear or front lower panel.
• Inspect wiring: Check the heater terminals and wiring harness for burns, loose connections, or corrosion.
• Check for leaks: Look for signs of water leakage around the heater seal, which can damage wiring and controls.
• Component replacement: If the heater is visibly damaged or tests open (technician test), replace the heating element. If wiring and heater are good, the control board heater relay may be faulty and the CCU may need replacement.

Warning: Testing heater resistance and live voltage should only be done by someone trained to work with electricity.
