KitchenAid Dishwasher Error Code 6-2

Error code 6-2 indicates an electrical problem in the fill valve circuit. The control board has detected an open circuit, which can be caused by a loose wiring connection, a failed fill valve solenoid, or a blown fuse on the control board. The dishwasher stops operation when this fault is detected because it cannot confirm proper water fill function. Diagnosis requires checking resistances and continuity through the fill circuit with the power disconnected.

The dishwasher should not be used while this error code is active. The fault indicates an electrical problem in the fill circuit, which means the machine may not fill with water correctly. Running a cycle without proper water fill can damage the pump and other internal components. Disconnect power and complete the diagnosis before attempting to run the dishwasher again.

Resetting the dishwasher by disconnecting power may temporarily clear the display, but the error code will return if the underlying electrical fault has not been repaired. The control board detects the open circuit condition at the start of a fill cycle, so the code will reappear as soon as the dishwasher attempts to fill with water. The root cause in the fill valve circuit must be identified and corrected for the repair to hold.

Repairs that involve checking and reseating wiring connections are within reach for a confident DIYer comfortable working with appliance wiring. Replacing the fill valve solenoid is also a manageable repair with basic tools. However, diagnosing a blown fuse or failed drive circuit on the control board requires a multimeter and some electrical knowledge, so those repairs may be better suited to a technician.

Repair costs vary depending on which component has failed. Reseating a loose wiring connection costs nothing beyond your time. A replacement fill valve solenoid or inlet valve assembly typically ranges from $30 to $80 in parts. Control board repairs or replacements can range from $150 to $350 or more depending on the model. Adding a professional labor charge of $75 to $150 per hour is typical if you hire a technician.
