Jenn-Air Dishwasher Error Code Heated Dry LED + Clean LED

When both the Heated Dry LED and Clean LED illuminate together during the Field Service Test on a Jenn-Air dishwasher, it indicates a memory failure on the control board. The diagnostic routine was unable to read or write to the board's internal memory correctly. This is a hardware-level fault within the control board itself.

The repair itself involves replacing the control board, which is a task many experienced DIYers can complete. However, correctly entering the Field Service Test mode to confirm the fault code before and after replacement requires familiarity with Jenn-Air diagnostic procedures. If you are comfortable working with appliance electronics and can safely disconnect power, this repair is approachable with the right replacement part.

Repair costs depend on whether you hire a technician or do the repair yourself. A replacement control board for a Jenn-Air dishwasher typically costs in the range of $100 to $300 for the part alone, depending on the model. Professional labor to diagnose and replace the board can add another $100 to $200 to the total cost.

No, a power reset will not clear a memory failure error. Because the fault is caused by a failed memory component inside the control board, the error will return whenever the Field Service Test is run. The underlying hardware problem cannot be resolved by cycling power or resetting the appliance.

A memory failure on the control board means the appliance cannot reliably track or manage its own cycles and settings. Continued use is not recommended, as the board may behave unpredictably. It is best to stop using the dishwasher until the control board has been replaced.
