KitchenAid Dishwasher Error Code 10-1

Error code 10-1 on a KitchenAid dishwasher indicates the control board has detected an electrical fault in the detergent dispenser circuit. Specifically, the board is seeing either an open circuit or abnormal resistance reading from the dispenser solenoid, which is the component that physically opens the dispenser door during the wash cycle to release detergent. The fault can originate from a loose or corroded wire connection anywhere along the dispenser circuit or from a failed solenoid coil itself.

For a homeowner, this means the dishwasher has detected a wiring or component problem with the soap dispenser mechanism. The dispenser uses a small electromagnetic solenoid to pop open the detergent door at the right point in the wash cycle. When that solenoid or the wiring leading to it breaks down electrically, the control board flags code 10-1. Your dishes may come out without soap, or the cycle may be interrupted entirely depending on how your model handles the fault.

Diagnosing this code requires disconnecting power and using a multimeter to measure the resistance of the dispenser solenoid and check continuity through the dispenser wiring harness. A healthy solenoid will show a specific resistance value within its rated range. An open reading (infinite resistance) confirms a failed solenoid or broken wire connection that needs repair or replacement.
