KitchenAid Dishwasher Error Code 2-2

Error code 2-2 means the installed control board is not compatible with the LCD display module on your dishwasher. The dishwasher detects this mismatch automatically and displays the fault to alert a technician. This is a hardware compatibility issue, not a sensor or wiring fault. The correct control board for an LCD-equipped model must not have a 4-pin user interface connector at position P1B.

No, resetting the dishwasher will not clear the 2-2 error code. This fault is triggered every time the control runs its startup check and detects the hardware mismatch between the control board and the LCD display module. The error will continue to appear until the incompatible control board is replaced with the correct one.

The primary cost involved is the replacement control board, which typically ranges from $100 to $300 depending on the specific model. If a professional technician performs the repair, labor costs can add another $75 to $150 to the total. If the wrong board was installed as part of a recent repair, the supplier or technician responsible may be able to exchange the part, which could reduce out-of-pocket costs.

The fix requires replacing the incompatible control board with one that is correctly specified for your LCD display model. First, inspect the current control board and check whether a 4-pin connector is present at position P1B. If it is, the board is the wrong type and must be replaced. A technician familiar with dishwasher control systems should handle this repair to ensure the correct part is sourced and installed.

The dishwasher is unlikely to operate normally while displaying error 2-2, as the control board and display module are not communicating correctly. Attempting to run cycles in this state is not recommended, since the control may not be able to manage wash functions reliably. The unit should be repaired before returning to regular use.
