How to Fix E4 F8 Error on Your Dishwasher

Dishwashers have become an indispensable part of our daily lives, making the chore of cleaning dishes a breeze. However, like any other appliance, they are prone to occasional malfunctions. One frustrating error code that users often encounter is the E4 F8 error. In this article, we will guide you through the steps to fix this error and get your dishwasher back in working order.

Understanding the E4 F8 Error

The E4 F8 error code is a common issue in many dishwasher models, and it usually indicates a problem with the water supply. When your dishwasher displays this error, it’s trying to tell you that it’s not receiving enough water to function properly.

Checking the Water Supply

The first step in resolving the E4 F8 error is to check your dishwasher’s water supply. Here’s what you should do:

1. Turn Off the Dishwasher

Before you start troubleshooting, make sure your dishwasher is turned off and unplugged for safety.

2. Inspect the Water Inlet Valve

The water inlet valve is responsible for letting water into the dishwasher. Check if it’s clogged or malfunctioning. If you notice any issues, it may need to be replaced.

3. Examine the Water Supply Hose

Inspect the water supply hose for kinks, blockages, or leaks. Ensure that the hose is properly connected to both the dishwasher and the water source.

4. Check Water Pressure

Low water pressure can trigger the E4 F8 error. Ensure that the water pressure in your home is sufficient for the dishwasher to operate correctly.

Cleaning the Filters

Dishwashers have filters that prevent debris from entering the system. If these filters are clogged, it can lead to water supply problems and the E4 F8 error. Here’s how to clean them:

5. Remove the Lower Rack

Take out the lower rack of the dishwasher to access the filters.

6. Locate and Remove Filters

Find the filters at the bottom of the dishwasher and remove them carefully.

7. Rinse Filters

Rinse the filters under running water to remove any accumulated debris. Make sure they are clean before reinstalling them.

Restarting the Dishwasher

After cleaning the filters and ensuring a proper water supply, it’s time to restart your dishwasher:

8. Reassemble Filters

Place the cleaned filters back into their respective slots in the dishwasher.

9. Turn On the Dishwasher

Plug in the dishwasher and turn it on to see if the error has been resolved. If the E4 F8 error persists, proceed to the next step.

Professional Help

If you’ve followed the steps above and the error code still haunts your dishwasher, it might be time to seek professional assistance. A certified technician can diagnose and fix any underlying issues that may be causing the error.


Dealing with dishwasher errors like E4 F8 can be frustrating, but with the right troubleshooting steps, you can often resolve the issue on your own. By checking the water supply, cleaning the filters, and restarting the dishwasher, you increase your chances of enjoying clean and spotless dishes once again.
