What the 6-6 error code actually means

Your Jenn-Air dishwasher is detecting a problem with the water filling system, specifically that water may be entering the tub in an uncontrolled way and cannot be properly shut off. This could be caused by a stuck-open water inlet valve or a faulty control board component that manages the valve. Because uncontrolled filling can lead to an overflow, it is best to stop using the dishwasher and have a technician inspect it before running another cycle.

Questions people ask about 6-6

What does error code 6-6 mean on a Jenn-Air dishwasher?
Error code 6-6 means the control board has detected either a shorted triac in the fill valve circuit or a fill valve that is mechanically stuck open. Both conditions cause the dishwasher to fill with water when it should not. The first step is to check whether the unit is still filling with the door open, which identifies which component is at fault.
How do I diagnose a 6-6 error code on my Jenn-Air dishwasher?
Open the dishwasher door and observe whether water continues to fill the tub. If it does, the fill valve is mechanically stuck open and needs replacement. If filling stops with the door open, run the Service Diagnostics Test Cycle and advance it until the detergent dispenser opens. At this point the fill valve should be off. If the dishwasher is still filling at this stage, disconnect power and replace the control board.
Can I replace the fill valve myself to fix a 6-6 code, or do I need a technician?
Replacing the fill valve on a Jenn-Air dishwasher is a DIY-friendly repair if the stuck valve is confirmed as the cause. You will need to shut off the water supply, disconnect the inlet hose, unplug the dishwasher, and swap the valve, which is typically mounted at the bottom rear of the unit. Replacing the control board is also achievable for a confident DIYer. If you are unsure about the diagnosis or uncomfortable with electrical components, a qualified appliance technician can complete either repair safely.
Is it safe to use my Jenn-Air dishwasher when it shows a 6-6 error?
No, you should not continue using the dishwasher with a 6-6 error active. A fill valve stuck open or a shorted triac can cause the dishwasher to overfill, which risks water damage to your floor, cabinetry, and the unit itself. Disconnect power or shut off the water supply to the dishwasher until the fault is diagnosed and repaired.
How much does it cost to fix a 6-6 error on a Jenn-Air dishwasher?
If only the fill valve is stuck open, the part typically costs between $30 and $80 and is a manageable DIY repair for someone comfortable disconnecting water supply lines and electrical connectors. If the control board triac is shorted, a replacement control board generally runs $150 to $350 for the part alone. Professional labor can add $100 to $200 depending on your market, making a control board repair potentially approach $500 total.
