Dishwasher shows F7E2; unit may overheat, emit excessive steam, or shut down mid-cycle.

Safety: Immediately turn off power at the breaker and allow the dishwasher to cool completely.

• Inspect for damage: Check inside the tub for signs of melting plastic or scorch marks. Do not use the dishwasher until the fault is corrected.
• Test heater to ground: With power off and wires removed, measure resistance from each heater terminal to ground (tub). Any continuity indicates a shorted element; replace the heating element.
• Check thermistor: Verify the temperature sensor is properly connected and not damaged. Replace if readings are out of spec.
• Control board replacement: If the heater is good but continues to energize when it should be off, the control board heater relay is likely welded closed and the board must be replaced.

Warning: Overheating can cause fire or severe damage. Do not restore power until defective components are replaced.
