Kenmore Dishwasher Error Code 1-2

Error code 1-2 means the control board has detected damaged or corrupted memory, or incompatible software components within its microcontroller. This is an internal fault with the control board itself, not a sensor or plumbing problem. The board cannot operate reliably in this state and must be replaced.

No, you should not continue running the dishwasher with code 1-2 active. A control board with corrupted or incompatible memory may not correctly manage water fill, drain timing, or heating elements, which can lead to flooding, incomplete cycles, or other damage. Stop using the appliance until the control board is replaced.

No, a simple reset will not clear error code 1-2. Because this code reflects actual physical or firmware damage inside the control board's microcontroller memory, cycling power or pressing button sequences will not resolve the underlying fault. The error will return immediately or at next startup until the control board is replaced.

The fix for error code 1-2 is to disconnect power to the dishwasher and replace the main control board. There is no software reset or reprogramming option available for this fault because the problem is inside the board's own microcontroller memory. Order a replacement control board that matches your specific Kenmore model number, or have a technician source and install it.

A replacement Kenmore dishwasher control board typically costs between $100 and $250 for the part, depending on the model. If you hire a technician, expect to add $75 to $150 for labor. Replacing the control board is a moderate DIY repair that requires disconnecting wiring harnesses and mounting the new board, which many homeowners with basic appliance repair experience can complete in under an hour.
