Maytag Dishwasher Error Code Delay LED + Heated Dry LED

This LED combination indicates a memory or software failure detected during the Field Service Test on a Maytag dishwasher. The fault is internal to the main control board and means the board cannot properly access or verify its onboard memory. It is not a sensor or mechanical fault, and it points directly to the control board as the failed component.

A simple power reset is unlikely to permanently clear this error because the fault reflects an internal memory failure on the control board rather than a temporary condition. The board may resume operation briefly after a reset, but the underlying hardware problem will typically cause the fault to return. Replacing the control board is the recommended resolution.

The primary cost for this repair is the replacement main control board, which typically ranges from $100 to $250 for the part depending on the specific model. If a technician performs the repair, labor costs will add to that total, bringing the overall repair cost to a range of roughly $200 to $450. Getting a repair estimate before proceeding is advisable to weigh the repair cost against the age and condition of the appliance.

Confirming this fault requires entering the Field Service Test mode, which involves a specific button sequence and knowledge of the test procedure. If the memory failure is confirmed, the repair requires replacing the main control board. This is a task that knowledgeable DIYers can perform, but it does require comfort with disassembling the dishwasher door panel and handling electronic components.

A control board memory failure means the dishwasher's operating logic is unreliable, so continued use is not recommended. The board may not correctly control wash cycles, water fill, or heating functions, which could lead to incomplete cycles or unpredictable behavior. It is best to avoid running the appliance until the fault is diagnosed and the control board is replaced.
