What the 6-8 error code actually means

Your Jenn-Air dishwasher is displaying error code 6-8 because the control board has detected an electrical problem with the rinse aid dispenser, which is the compartment that releases the liquid that helps your dishes dry spot-free. If your dishwasher has a built-in water softener, this code may instead point to a fault with the valve that refreshes the softener system using salt. In either case, the dishwasher has noticed something is not working correctly with one of these components and needs attention before it can operate normally.

Questions people ask about 6-8

What does error code 6-8 mean on a Jenn-Air dishwasher?
Code 6-8 indicates a problem with the rinse aid dispenser system. On most Jenn-Air dishwashers, this means the control board detected an issue with the rinse aid dispenser, most often because the rinse aid is empty or very low. On models that include a built-in water softener, this code can also signal an electrical fault with the regeneration valve.
Can I still use my Jenn-Air dishwasher when code 6-8 is showing?
Yes, the dishwasher will generally continue to operate through wash cycles even with code 6-8 active. However, running cycles without rinse aid will result in water spots and poor drying performance. If the code is related to a regen valve fault on a water softener model, continuing to use the machine without addressing it may reduce cleaning effectiveness over time. Filling the rinse aid or having the valve repaired promptly is advisable.
Why does code 6-8 keep coming back on my Jenn-Air dishwasher even after I add rinse aid?
If code 6-8 reappears shortly after filling the dispenser, the dispenser's level sensor or the dispenser assembly itself may be defective and is not reading the fill level correctly. It is also possible the dispenser door is not sealing or opening properly, causing the rinse aid to drain out faster than expected. Check the dispenser cap for cracks and the door mechanism for obstructions. If those check out, the dispenser assembly likely needs to be replaced.
How do I fix error code 6-8 on my Jenn-Air dishwasher?
Start by opening the rinse aid dispenser cap, usually located on the inside of the door next to the detergent dispenser, and check the level using the sight window or indicator gauge. Fill it with standard dishwasher rinse aid, close the cap securely, and run a cycle. The code should clear on its own if a low rinse aid level was the cause. If the code returns after filling, inspect the dispenser assembly and its wiring for damage, or contact a technician to test the regen valve on water softener models.
How much does it cost to repair error code 6-8 on a Jenn-Air dishwasher?
If the fix is simply adding rinse aid, the cost is just the price of a bottle of rinse aid, typically under $10. If the rinse aid dispenser assembly needs replacement, the part generally runs $30 to $80 depending on the model, plus labor if a technician installs it. A regeneration valve replacement on a water softener model can cost $50 to $120 for the part alone. Labor for a service call typically adds $100 to $200 depending on your area.
