Jenn-Air Dishwasher Error Code 9-2

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.

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.

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.

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.

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.
