Jenn-Air Dishwasher Error Code 6-4 or F6E4

Encountering the error code 6-4 or F6E4 on your Jenn-Air dishwasher indicates a specific issue: the float switch is open. Here’s a detailed breakdown of this error code and a step-by-step guide on how to address it yourself:

1. Identify the Problem:

The error code points to the float switch being in an open position. This can happen due to a few reasons, such as items lodged under the overfill float, a malfunctioning water inlet valve, or a defective float switch.

2. Check for Obstructions:

Inspect the area under the overfill float for any items that might be causing it to stay open. Clear away any debris or objects that could be preventing the float from returning to its normal position.

3. Examine the Water Inlet Valve:

A faulty water inlet valve can also trigger the float switch error. If the valve is stuck open, the dishwasher will continuously fill, activating the float switch. Look for any signs of the water inlet valve being stuck and, if necessary, replace it to resolve the issue.

4. Test the Float Switch:

To determine if the float switch itself is defective, start by unplugging the dishwasher to ensure safety. Then, check the resistance through the overfill float switch using a multimeter. With the dishwasher tub empty or nearly empty, you should measure near 0 ohms of resistance. If you measure infinite resistance, it indicates a problem with the float switch, and replacement is recommended.

5. DIY Replacement of Float Switch:

If you’ve confirmed that the float switch is faulty, you can replace it yourself. Consult your dishwasher’s manual for guidance on locating and removing the float switch. Ensure the dishwasher is unplugged before attempting any replacement. Purchase a compatible replacement float switch and install it according to the manufacturer’s instructions.

By following these steps, you can troubleshoot and potentially resolve the Jenn-Air dishwasher error code 6-4 or F6E4 on your own. However, if you encounter difficulties or the issue persists, it may be advisable to seek professional assistance.
