What the dishwasher is detecting
The control monitors the heater circuit. If the heater is still energized after the control has turned it off, it records this code because it has lost control of the heat.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A failed heater drive circuit (relay) on the main control.
- Documented Heater or connections damaged by overheating or a short, or a heater shorted to ground (named on newer platforms).
Safe checks you can make
- Switch off the dishwasher's breaker. If you notice a burning smell, melted plastic or a heater that stays hot with the dishwasher off, leave it off.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Inspects the heater and its connections for overheating or shorts.
- Confirms the control's heater circuit fault before replacing the control and any damaged parts.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dishwasher main control board replacement | $260–$590 | Moderate |
| Dishwasher heating element or drying fan replacement | $190–$410 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Stop using it until it is checked. Stop using the dishwasher and switch off its breaker. A heater that cannot be switched off can melt dishes and parts and is a fire risk.

Repair or replace?
A fault code alone rarely justifies replacing a dishwasher. Most F7E2 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 9–12-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
