How to Fix Whirlpool Dishwasher Error Code F8 E4
Dishwashers are a lifesaver in the kitchen-that is, until they don’t work anymore. In this case, if your Whirlpool dishwasher has displayed the error code F8 E4, don’t freak out. This common error may appear confusing at first but often is something you can resolve with a little troubleshooting on your own.
Here, we will guide you through what the F8 E4 error code means, why it occurs, and most importantly, how you can fix it.
What does the F8 E4 error code mean?
The F8 E4 code on the Whirlpool dishwasher indicates a fault either with the sump or with the flow system of your appliance. In other words, it is unable to detect the right water level. This is related to excessive foam or not properly drained water.
This is usually an error triggered when the machine senses that water hasn’t passed through the system properly to cause further damage or flooding.

What Causes the Error?
A number of things can cause this F8 E4 error code; however, some of the most common ones include:
Too Much Detergent/Rinse Aid Foam: Incorrect detergent or excessive usage creates extra foam that interferes with the water flow detection system of the machine.
Clogged Drain Filter: The filter might be obstructed, affecting the smooth flow of water out of the dishwasher.
Blocked Drain Hose: Kinks or clogs in the drain hose may block the proper water exit.
Faulty Water Level Sensor: If the sensor that monitors water levels in the dishwasher malfunctions, it can trigger a false error.
Now that you know the possible causes, it is time to focus on solutions.
Step-by-Step Guide to Fixing the F8 E4 Error
Here’s a breakdown of steps to troubleshoot and resolve the problem effectively.
1. Turn Off the Dishwasher
Start by unplugging the dishwasher and cutting the power for safety. You do not want to work on an electrical appliance when it’s connected.
2. Check for Excess Detergent or Foam
If you think it’s excess foam from detergent, open the dishwasher door and take a peek. The cause of this is using too much detergent or the wrong type of soap, such as hand-washing soap.
Solution: Soak up the excess foam using a sponge. Run the dishwasher while rinsing; run a rinse-only cycle without detergent to get rid of the remaining foam.
3. Check the Drain Filter
Most filters would be at the bottom of a dishwasher. There could be pieces of food, grease, and particles that build up after being used over some time.
Solution: Pull the bottom rack forward to see the filter. Remove the filter: refer to how to remove your filter from the user manual Rinse underneath warm water for dirt and grease to clear out. Put that back well.

4. Check the Drain Hose
If the filter is clean and it seemingly remains in this condition, the fault could be in the drain hose.
Solution: The drain hose normally attaches to the rear side of the dishwasher. Look for bends that can hamper water flow inside the hose. If clogged, gently remove the hose and begin washing it with warm water.

5. Check the Water Level Sensor
The F8 E4 error code can also mean a problem with the sensor that reports water levels. If everything else doesn’t work, then it is worth checking this component.
Solution: Find the water level sensor; it depends on the model of your dishwasher. Look for any signs of visible damage or malfunction. It could be a matter of a good clean, but replace it if faulty. Contact an electrician if the above is outside your competence threshold.
6. Run the Dishwasher
After following the steps above, reconnect the appliance to power and start it. Use a short rinse cycle and observe if the error code has been erased.
When to Call a Professional
If you’ve followed all the troubleshooting steps and the F8 E4 error code still appears, it’s time to call a technician. The issue may require a more in-depth diagnosis or repair, such as replacing internal components or addressing electrical faults.

Tips to Prevent Future Errors
Use dishwasher detergent specifically designed for dishwashers (avoid handwashing soap). Follow the manufacturer’s recommendation on the amount of detergent to use. Regularly clean the drain filter to prevent accumulation of food particles to block the drain. Periodically check the blockage or any damage in drain hose. Take yearly servicing for your dishwasher to maintain the good condition.
Conclusion
The F8 E4 error code is bound to derail your routine, but most often, it is a problem that can be resolved with a little patience and some basic troubleshooting. Understanding what the error means and going through the steps above will get your Whirlpool dishwasher working in no time.
If you have fixed the problem and wish to keep your dishwasher running without hiccups, why not put in a reminder once every month to clean this filter? Small things like this will prevent you from having future headaches.
