Jenn-Air Dishwasher Error Code 6-8 or F6E8

Encountering the error code 6-8 or F6E8 on your Jenn-Air dishwasher indicates a problem with the water softener regeneration valve. Don’t fret – we’ve broken down the troubleshooting process for you, including a step-by-step DIY guide to get your dishwasher back on track.

Understanding the Issue:

This error arises when the dishwasher’s control board detects a failure in the water softener regeneration valve, a crucial component responsible for maintaining water quality during the wash cycle.

DIY Troubleshooting Steps:

1. Safety First: Unplug the Dishwasher

   • Before diving into troubleshooting, ensure your safety by unplugging the dishwasher from the power source.

2. Inspect Wiring Connections:

   • Examine the wiring connections between the electronic control board and the water softener regeneration valve.
   • If you spot any loose wires, reconnect them securely.
   • Look for any visible signs of damage on the wires and repair or replace them as needed.

3. Check Resistance with a Multimeter:

   • Use a multimeter to check the resistance through the wires connecting the valve circuit to the electronic control board.
   • The meter should read between 890 and 1,090 ohms. If it falls within this range, it indicates a functional regeneration valve circuit.
   • If the resistance is within the range, but the error persists, it suggests a malfunction in the electronic control board.

4. Electronic Control Board Replacement:

   • If the resistance is within the specified range but the error continues, it’s time to replace the electronic control board.
   • The control board may not be sensing the regeneration valve circuit properly.

5. Direct Resistance Measurement at Regeneration Valve:

   • If the multimeter measures infinite resistance directly at the regeneration valve, it signals a potential issue with the water softener tank assembly.
   • In this case, consider replacing the water softener tank assembly to resolve the problem.

6. Check Wire Harness:

   • If the multimeter reads between 890 and 1,090 ohms at the regeneration valve but shows infinite resistance through the regeneration valve circuit, inspect the wire harness.
   • A damaged wire harness could be the culprit. Repair or replace the wire harness to restore proper functionality.

By following these detailed DIY steps, you can address the Jenn-Air dishwasher error code 6-8 or F6E8 related to water softener regeneration valve failure. Remember to prioritize safety and, if needed, seek professional assistance for more complex issues.
