What Heated Dry LED + Clean LED means on a Jenn-Air dishwasher

The simultaneous illumination of the Heated Dry LED and Clean LED on a Jenn-Air dishwasher during the Field Service Test indicates a memory failure within the control board. This condition points specifically to an internal fault in the non-volatile memory (EEPROM or similar storage) embedded in the control board's microcontroller. The memory subsystem is responsible for storing operational parameters, cycle data, and configuration settings. When the Field Service Test routine runs a self-diagnostic check and cannot read from or write to this memory correctly, it flags the failure using this specific LED combination.

The control board's memory is used continuously during operation to track cycle progress, retain user preferences, and log diagnostic information. A memory failure means the board can no longer reliably perform these functions. This type of fault is almost always hardware-level, originating inside the control board itself rather than in any external wiring or sensor. Corrupted memory chips do not self-repair, and the failure will persist across power resets.

Because the fault is internal to the control board's integrated circuitry, the recommended and only practical corrective action is full control board replacement. There are no field-level repairs for a failed memory chip on a dishwasher control board. Technicians should confirm the error is reproducible through the Field Service Test before ordering a replacement board to rule out any intermittent conditions related to power supply fluctuations at the time of initial testing.

Common causes of Heated Dry LED + Clean LED

  1. 01

    Failed control board memory chip

    Part replacement

    The EEPROM or non-volatile memory component on the control board has failed internally. This is the direct cause indicated by this error and is confirmed when the Field Service Test reproduces the LED combination.

  2. 02

    Control board corruption from power surge

    Part replacement

    A voltage spike or power surge can corrupt or permanently damage the memory on the control board. If the error appeared after a power outage or electrical event, this is a likely contributing factor.

  3. 03

    Age-related control board degradation

    Part replacement

    Memory components on control boards can degrade over time with normal use. Older dishwashers experiencing this error for the first time without an obvious triggering event may simply have reached end-of-life for the board's memory.

  4. 04

    Moisture or corrosion on control board

    Part replacement

    Exposure to steam or condensation can corrode the control board's circuitry, including memory components. Inspect the board for visible corrosion, discoloration, or moisture damage before ordering a replacement.

Frequently asked questions about Heated Dry LED + Clean LED

What does Heated Dry LED + Clean LED mean on a Jenn-Air dishwasher?
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.
Will resetting my Jenn-Air dishwasher clear this error?
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.
Can I fix a Jenn-Air dishwasher memory failure myself?
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.
Is it safe to keep using my dishwasher if this error appears?
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.
How much does it cost to fix a Jenn-Air dishwasher with a memory failure error?
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.
