Whirlpool Dishwasher Error Code 9-2

Code 9-2 means the control board has detected that the diverter is stuck on due to a fault in the diverter drive circuit. The diverter is the motorized component that routes water to different spray arms during a cycle. The fault can originate from a failed driver circuit inside the control board or from the diverter motor itself shorting or overheating.

Running the dishwasher with code 9-2 active is not recommended. A shorted diverter circuit can indicate an ongoing electrical fault that may worsen with continued use, potentially causing additional damage to the control board or wiring. Disconnect power until the diverter motor, wiring, and control board have been inspected and the faulty component replaced.

Both components can cause code 9-2. The control board is listed as the primary fix because the fault originates in the diverter drive circuit on the control. However, a diverter motor that has shorted or overheated can pull abnormal current through that same circuit, triggering the code. Always inspect the diverter motor and its connections for heat damage or shorts before assuming the control board is the only issue.

Start by unplugging the dishwasher or disconnecting power, then inspect the diverter motor and its wiring connections for signs of overheating, melting, or shorting. If you find visible damage, replace the diverter motor. If the motor and wiring look clean, the control board is the most likely culprit and should be replaced. Because this repair involves working on the control board and electrical components, a technician is advisable if you are not comfortable with appliance wiring.

If the diverter motor is the cause, a replacement motor typically costs between $30 and $80 in parts. A replacement control board is the more expensive repair, usually ranging from $100 to $250 in parts depending on the model. Add $100 to $200 for labor if you hire a technician. DIY repair is feasible if you are comfortable disconnecting and reconnecting appliance wiring and following a model-specific disassembly guide.
