Kenmore Dishwasher Error Code 10-1

Code 10-1 means the control board has detected an electrical problem in the detergent dispenser circuit. The issue could be a loose wiring connection, a failed dispenser solenoid or wax motor, a blown fuse on the control board, or a faulty dispenser drive circuit on the board itself. Start by unplugging the dishwasher and checking resistances at the dispenser solenoid or wax motor and inspecting all connections in the circuit.

Technically the dishwasher may still run a cycle, but with a 10-1 fault active, the detergent dispenser will not open correctly, meaning dishes will not be properly cleaned. Running cycles without functioning detergent dispersion can also leave food debris buildup over time. It is better to diagnose and resolve the fault before regular use.

Unplug the dishwasher first, then disconnect the wiring harness connector at the dispenser solenoid or wax motor. Set a multimeter to the resistance (ohms) setting and probe the solenoid terminals. A healthy solenoid will typically show a resistance reading in the range specified in your model's service manual, often between 500 and 1500 ohms depending on design. A reading of infinite resistance (OL or open loop) confirms the solenoid has failed and needs replacement. If resistance reads normal, move on to checking wiring connections and the control board fuse.

Begin by disconnecting power to the dishwasher, then locate and inspect all wiring connections in the dispenser circuit for looseness or corrosion. Use a multimeter to measure the resistance of the dispenser solenoid or wax motor; a reading of infinite resistance (open circuit) means the solenoid has failed and needs replacement. Also check for a blown fuse on the control board in the dispenser circuit. If connections and the solenoid test good but the error returns, the control board's drive circuit is likely faulty and the board will need to be replaced.

If the fix is simply reseating a loose connector, there is no parts cost. A replacement dispenser solenoid or wax motor typically runs between $20 and $60 depending on the specific Kenmore model. A replacement control board is the most expensive repair, generally ranging from $100 to $250 for the part alone. If you are comfortable using a multimeter and working with appliance wiring, this is a repair many DIYers can handle; a professional technician visit will add $100 to $200 in labor on top of part costs.
