What 9-2 means on a Jenn-Air dishwasher

Error code 9-2 on a Jenn-Air dishwasher indicates the control board has detected a fault in the diverter drive circuit. Specifically, the control is unable to properly drive the diverter motor, meaning the circuit responsible for sending power signals to the diverter has malfunctioned at the control level. This code triggers when the control detects the diverter is stuck in one position and cannot respond to switching commands, pointing either to a shorted or overheated diverter motor or to a failed diverter drive circuit on the control board itself.

The diverter is the component that directs water flow between the upper and lower spray arms during a wash cycle. When it gets stuck, water cannot be properly distributed throughout the tub, which means one set of spray arms may not receive water at all. Your dishes will not be cleaned properly, and the dishwasher may stop mid-cycle as a result.

The two most likely culprits are a burned or shorted diverter motor and its wiring, or a failed control board. Inspecting the diverter motor and its connector for visible signs of heat damage, melted plastic, or burnt wiring is the first physical check to perform. If no damage is found there, the control board itself is the source of the fault and will need replacement.

Common causes of 9-2

  1. 01

    Failed diverter drive circuit on the control board

    Part replacement

    The control board contains a dedicated drive circuit that sends power to the diverter motor. When this circuit fails or burns out internally, the control can no longer operate the diverter and throws the 9-2 code even if the diverter motor itself is functional.

  2. 02

    Shorted or overheated diverter motor

    Part replacement

    A diverter motor that has internally shorted or overheated draws excessive current, which can damage the drive circuit on the control board and prevent normal operation. Visible signs include melted plastic on the motor housing, discolored wiring, or a burnt smell near the motor.

  3. 03

    Damaged wiring harness or connector at the diverter motor

    Wiring / connection

    A chafed, pinched, or heat-damaged wire between the control board and the diverter motor can cause a short or open in the drive circuit, triggering the 9-2 fault. Connector pins that have melted or corroded together can produce the same result.

Frequently asked questions about 9-2

What does error code 9-2 mean on a Jenn-Air dishwasher?
Error code 9-2 means the control board has detected that the diverter is stuck and cannot be driven by the diverter drive circuit. The diverter switches water flow between the upper and lower spray arms, and when the control cannot command it to move, this code is set. The root cause is either a failed drive circuit on the control board or a shorted and overheated diverter motor.
How do I fix error code 9-2 on my Jenn-Air dishwasher?
Start by disconnecting power to the dishwasher, then inspect the diverter motor and its wiring harness for any visible signs of overheating, melted insulation, or burnt connectors. If damage is present, replace the diverter motor and any damaged wiring before restoring power. If the motor and wiring look clean with no heat damage, the diverter drive circuit on the control board has failed and the control board itself needs to be replaced.
Can I still use my Jenn-Air dishwasher with a 9-2 error code active?
Running the dishwasher with a 9-2 code active is not advisable. Because the diverter cannot switch water flow between spray arms, wash performance will be significantly reduced and dishes will not clean properly. More importantly, if the underlying cause is a shorted diverter motor, continued operation could cause further electrical damage to the control board or wiring harness, making the repair more expensive.
How much does it cost to fix a 9-2 error on a Jenn-Air dishwasher?
If the diverter motor is the cause, replacement motors typically range from $40 to $100 for the part. A replacement control board for a Jenn-Air dishwasher generally runs between $150 and $350 depending on the model. If you hire a technician, expect to add $100 to $200 in labor. Inspecting the diverter motor and wiring yourself before ordering parts is worth doing, since visible heat damage will confirm whether the motor or the control board is the primary failure.
Does a 9-2 code on a Jenn-Air dishwasher always mean I need a new control board?
Not always. The 9-2 code can be caused by a shorted or overheated diverter motor that has damaged the control's drive circuit, so if the motor itself is the source of the short, replacing only the control board without also replacing the motor could cause the new board to fail again. Always inspect the diverter motor and its wiring harness for heat damage first. Replace any damaged components before installing a new control board.
