GE Dishwasher Error Code Heated Dry

On a GE dishwasher, the Heated Dry indicator is used to display a wash temperature fault, not a drying error. It means the dishwasher failed to reach the minimum wash temperature of 120°F in at least 2 of the past 3 wash cycles. The control board tracks this based on thermistor readings during the wash phase. The cause is typically low incoming water temperature, a failed thermistor, a bad heating element, or a tripped tub TCO.

The dishwasher will generally still run cycles, but water that does not reach 120°F may not fully sanitize dishes or dissolve detergent as effectively. There is no immediate safety hazard to the appliance from this fault, but dish hygiene may be compromised. It is best to diagnose and repair the issue before relying on the dishwasher for sanitizing loads.

Repair costs vary depending on which component has failed. A thermistor replacement is typically a lower-cost repair, often ranging from $40 to $120 including parts and labor. A heating element or tub TCO replacement may cost between $80 and $200 depending on parts pricing and local labor rates. If the issue is simply a water heater setting, there may be no parts cost at all.

Start by confirming that your home's hot water supply is at or above 120°F, as low supply temperature is the most common cause. If the supply temperature is adequate, the next steps are to test the thermistor for accurate resistance readings, check the tub TCO for continuity, and verify heating element operation through the dishwasher's service mode. Replacing whichever component tests as faulty should clear the error once the underlying issue is corrected.

A reset may temporarily clear the displayed fault, but the error will return if the root cause is not fixed. The control board tracks wash temperature across multiple cycles, so it will re-trigger the fault after 2 of the next 3 wash cycles again fall below 120°F. Clearing the code without addressing the underlying problem provides only a short-term workaround.
