Kenmore Dishwasher Error Code 6-4 or F6E4

When your Kenmore dishwasher displays the error code 6-4 or F6E4, it’s telling you that the float switch is open. This error code indicates a potential issue with the dishwasher’s float switch mechanism. Here, we’ll delve deeper into this error and guide you through troubleshooting steps to help you resolve it.

The float switch is a crucial component in your dishwasher’s operation. It’s a small device located at the base of the dishwasher’s tub. The float, typically made of plastic, rises with the water level during the wash cycle. When the water reaches a certain level, the float activates the float switch, signaling to the dishwasher that it should stop filling with water. This prevents overfilling, which could lead to water damage in your kitchen.

Troubleshooting the 6-4 or F6E4 Error:

Here are steps to troubleshoot and potentially resolve the error:

1. Check for Blockages: Inspect the area around the float switch for any debris or foreign objects that might be preventing the float from moving freely. Even a small item under the float can trigger the error.

2. Ensure Proper Movement: Gently press down on the float to make sure it moves freely up and down. It should not be stuck in the up position, which would indicate a problem.

3. Inspect the Inlet Water Fill Valve: The error can also occur if the dishwasher’s water inlet valve isn’t shutting off properly when the dishwasher is turned off. To check this, you may need to turn off the water supply to the dishwasher and examine the valve for any leaks or malfunctions. It may require cleaning, repair, or replacement.

4. Power Cycle the Dishwasher: Sometimes, simply turning off the dishwasher, unplugging it, or shutting off its circuit breaker for a few minutes and then restarting it can reset the error code.

5. Consult Your Owner’s Manual: Your Kenmore dishwasher’s owner’s manual can be a valuable resource for troubleshooting specific error codes. It may offer additional guidance and information on your dishwasher’s float switch and inlet valve.

If you’ve gone through these troubleshooting steps and the 6-4 or F6E4 error persists, it’s a good idea to seek professional assistance. The issue may require advanced diagnostics, parts replacement, or adjustments that are best handled by a trained technician.
