What 6-2 means on a Jenn-Air dishwasher

Error code 6-2 on a Jenn-Air dishwasher indicates the control board has detected an electrical fault in the fill valve circuit. Specifically, the board is seeing an open circuit condition, meaning electrical continuity is broken somewhere between the control board and the fill valve solenoid. This can be caused by a loose or corroded connector in the fill valve wiring circuit, or by a failed fill valve solenoid coil that has broken internally and reads as open resistance on a meter.

For homeowners, the fill valve is the component that controls water flowing into the dishwasher at the start of a cycle. When the control board tries to send power to this valve to begin filling, it detects that the circuit is broken and throws the 6-2 code to alert you that the dishwasher cannot fill properly. The machine stops the cycle rather than risk running without water.

Diagnosing this code requires disconnecting power and using a multimeter to check resistance across the fill valve solenoid terminals and all wiring connections in the fill circuit. A healthy solenoid reads within its specified resistance range; an open solenoid reads infinite resistance (OL). Any connector in the circuit can also be the culprit, so each connection point needs inspection.

Common causes of 6-2

  1. 01

    Open fill valve solenoid coil

    Part replacement

    The solenoid coil inside the fill valve can break internally, creating an open circuit that the control board detects as a fault. A multimeter placed across the solenoid terminals will read infinite resistance (OL) rather than the expected resistance value.

  2. 02

    Loose or disconnected wiring connector in fill circuit

    Wiring / connection

    A connector in the wiring harness between the control board and the fill valve can work loose over time from vibration or thermal cycling. This breaks the circuit and triggers the 6-2 code without any part actually failing.

  3. 03

    Corroded or damaged fill valve wiring harness

    Part replacement

    The wiring harness leading to the fill valve can develop corrosion at terminals or physical damage to the wire insulation, creating a break in the circuit. This is more common in dishwashers exposed to moisture intrusion near the valve area.

  4. 04

    Failed control board fill valve output

    Part replacement

    If all wiring and the solenoid itself test within spec, the control board's output circuit for the fill valve may have failed, preventing it from properly sensing or powering the valve. This is the least likely cause and should only be suspected after all other components have been verified.

Frequently asked questions about 6-2

What does error code 6-2 mean on a Jenn-Air dishwasher?
Error code 6-2 means the control board has detected an electrical problem in the fill valve circuit. The board is seeing an open circuit, which indicates either a loose or broken wiring connection somewhere in the fill valve circuit or a failed fill valve solenoid coil. The dishwasher stops operation because it cannot reliably control water fill.
How do I fix error code 6-2 on a Jenn-Air dishwasher?
Start by unplugging the dishwasher or shutting off the circuit breaker. Use a multimeter to test resistance across the fill valve solenoid terminals and inspect every wiring connector in the fill circuit. If the solenoid reads open (OL on the meter), replace the fill valve. If the solenoid reads correctly, reseat or replace any loose or corroded connectors. If all components test good, the control board may need replacement.
Can I still use my Jenn-Air dishwasher with a 6-2 error code active?
No. With a 6-2 code active, the dishwasher cannot complete a wash cycle because the fill valve circuit is not functioning correctly. Attempting to run the machine will result in a failed or incomplete cycle. The underlying fault needs to be resolved before the dishwasher will operate normally.
How much does it cost to fix a Jenn-Air dishwasher 6-2 error?
If the fix is simply reseating a loose connector, there is no parts cost. A replacement fill valve for a Jenn-Air dishwasher typically costs $30 to $80 in parts. If a technician diagnoses and performs the repair, expect a service call fee plus labor, bringing the total to roughly $150 to $250 depending on your area. Replacing a wiring harness or control board will increase costs significantly.
Is the 6-2 error on a Jenn-Air dishwasher a difficult repair for a homeowner?
Testing the fill valve solenoid and checking connectors is within reach for a homeowner who is comfortable using a multimeter and working around appliance wiring after disconnecting power. Replacing the fill valve itself is also a manageable DIY repair on most Jenn-Air dishwasher models, as the valve is typically accessible after removing the lower access panel. If testing points to the control board as the cause, professional diagnosis is advisable before purchasing that part.
