GE Dishwasher Error Code Heated Dry LED

The Heated Dry LED on a GE dishwasher indicates a wash temperature error. Specifically, the control board detected that water did not reach the minimum temperature of 120°F during 3 of the last 5 wash cycles. This is a persistent fault, not a single-cycle anomaly, and points to an issue with the water supply temperature, the heating element, or the temperature sensor.

Start by checking your home's water heater thermostat and confirming it is set to at least 120°F. Run the hot water tap at the kitchen sink for 30 to 60 seconds before starting a cycle to ensure hot water is already in the supply line. If the error persists after those steps, test the dishwasher's heating element for continuity with a multimeter and inspect the thermistor or thermostat. A failed heating element is the most common hardware cause and is a moderate DIY repair on most GE models.

The control board tracks wash temperature across 5 cycles, so the error will return if the underlying cause has not been fixed. Resetting the dishwasher clears the display temporarily but does not change the logged cycle history or repair the faulty component. If the error reappears within a few cycles after a reset, confirm your water heater supply temperature first, then move on to testing the heating element and thermistor before replacing parts.

The dishwasher will typically still run cycles with this error active, but washing below 120°F significantly reduces cleaning performance and leaves dishes under-sanitized. Detergents are formulated to activate at or above 120°F, so results will be noticeably worse. Using the dishwasher short-term while diagnosing the problem is generally safe for the machine, but it is not recommended for households that rely on the dishwasher to sanitize items like baby bottles or cutting boards.

If the fix is simply raising your water heater temperature, there is no cost involved. A replacement heating element for a GE dishwasher typically costs $20 to $60 for the part, and DIY installation is feasible with basic tools. A thermistor or thermostat is usually $10 to $30. If a control board replacement is needed, parts alone can run $80 to $200 or more, making professional diagnosis worthwhile before committing to that repair.
