KitchenAid Dishwasher Error Code F2E2

F2E2 indicates that the user interface board and the main control board have lost communication with each other. The fault is detected at the connection between the LCD display module and the P1C connector on the control. It is most often caused by a loose connector or an incompatible control board installed during a prior repair.

An F2E2 fault typically prevents normal operation, so running a wash cycle is generally not possible while the code is active. It is best to resolve the communication fault before attempting to use the appliance. Continuing to attempt operation with this fault present will not cause further safety concerns, but it will not clear the code either.

If the issue is simply a loose connector, the repair may cost nothing beyond the time to inspect and reseat the connection. If a user interface board replacement is needed, parts typically range from $80 to $200 depending on the model, with additional labor costs if a technician performs the work. A main control board replacement generally falls in the $100 to $300 range for parts alone.

Start by disconnecting power to the dishwasher, then locate the connection between the LCD display module and the P1C connector on the main control board and confirm it is fully seated and undamaged. If the connection is secure and the error returns, verify that the main control board installed is the correct part for your specific model number. If connections and compatibility are confirmed, the user interface board or main control board may need to be replaced.

A power reset may temporarily clear the code, but if the underlying issue is a loose connector or an incompatible control board, the fault will return once the machine attempts to establish communication again. A reset is a useful first step to confirm whether the fault is intermittent, but a physical inspection of the connections is necessary for a lasting fix.
