Dishwasher does not heat water or dry dishes; F7E1 or heater disabled error appears.

Safety First: Turn off power at the breaker before accessing the heater.

Visual inspection:

• Remove the lower access panel and inspect the heating element where it passes through the tub bottom.
• Look for breaks, heavy scaling, or burn marks on the element and its terminals.

Check wiring and thermostat:

• Inspect wires to the heater and high-limit thermostat (usually mounted on the tub or heater housing) for burns or loose connections.
• Reseat any loose connectors.

Testing (for qualified users):

• With power off and wires disconnected, test the heater for continuity. An open circuit means the element must be replaced.
• Test the high-limit thermostat for continuity; if open at room temperature, replace it.

If heater and thermostat are good:

• The main control board may not be energizing the heater and may need replacement.
