KitchenAid Dishwasher Error Code 1-1

Error code 1-1 means the control board detected the K2 pilot relay is stuck in the closed position. A relay stuck closed cannot be turned off by the control, which means components connected to that relay may receive power continuously when they should not. This is a control circuit fault that requires diagnosis of the relay and its connected loads.

Start by unplugging the dishwasher or shutting off power at the circuit breaker. Then inspect all components and wiring connected to the K2 pilot relay for signs of a short circuit, including checking harness connectors and individual loads with a multimeter. Replace any shorted components first, then replace the control board. Replacing the control board without fixing a downstream short will cause the new board to fail as well.

The control board is not always the first part to replace for a 1-1 error code. Because the fault can be caused by a short in any load connected to the K2 relay, you need to test those components and wiring first. If a shorted pump, valve, or harness is found and replaced, the existing control board may function normally once the short is cleared. Only replace the control board after confirming all connected loads are free of shorts.

No, you should not continue running the dishwasher with error code 1-1 active. A relay stuck closed can cause components to run outside their normal operating window, which risks overheating, premature component failure, or electrical damage. Unplug the dishwasher or disconnect power at the breaker until the fault is diagnosed and repaired.

If only the control board needs replacement, parts typically range from $100 to $250 depending on the model, with professional labor adding $100 to $200. If shorted downstream components such as a pump motor or valve also need replacement, total repair costs can rise significantly. DIY repair is achievable for someone comfortable using a multimeter and disconnecting appliance wiring, but if you are not confident testing for shorts, a qualified appliance technician can complete the diagnosis and repair accurately.
