You may have seen the code E4 F8 in your Maytag dishwasher. When the water level becomes faulty, this is the error code involved. This is a safety measure that saves you from flooding your kitchen due to excess water. However, fret not, fixing the Code E4F8 is by no means a herculean task. Let’s dive in!

What Does Code E4 F8 Mean?

The error Code E4 F8 in a Maytag dishwasher means there’s something wrong with the water level control. This activates the code that goes off when the sensors of the dishwasher sense too much water in the machine.

This could be due to several reasons:

Wrong Type of Detergent: Dishwasher detergents are formulated to be used in dishwashers only, unlike most other detergents. Dish soap that creates excessive amounts of suds will result in water overflowing out of the appliance. it should go without saying that using regular dish soap or the wrong type of dishwashing detergent is strictly prohibited.

Pre-Washing Dishes With Soap: Using too little or too much soap in a wash load is not a good thing as it may lead to additional foams because of the residual soap from the previous “pre” wash. Such bubbles (like suds) can increase water elevation setting off the Code E4 F8.

Installation Issues: Any mistakes in installing the dishwasher can cause problems with discharge and supply of water. As another instance of this, in case there has been no proper connection and placing of the drain hose, it can result in some overflow of water within the dishwasher as a case of more than enough water.

The code E4 F8, in essence, is a safety measure to prevent water from overflowing onto the kitchen floor. The dishwasher has a way of informing you that something is not right and needs your attention. However, whenever you see this code it’s essential to do something about it immediately to avert kitchen water leakage. It is always a good idea to consult with a professional to fix a problem if you’re unsure of how to solve it.

Fixing the E4 F8 Code

Step 1: Check for Suds

“Check for Suds” is the first step in diagnosing the Code E4F8 error on your Maytag dishwasher. To carry out the same step, open your dishwasher to see if there are suds, bubbles, or soap foam inside.

Dishwashers are developed to use unique detergents that do not form foam/sud. However, if regular dish soap or the wrong type of dishwasher detergent has been used, it gives too many suds. These suds may cause the water level to rise and cause a water overflow leading to Code E4 F8.

Suds in a dishwasher are a clear sign that dish soap rather than the dishwasher detergent was used. Therefore, you should switch off the dishwasher and give the suds time to dissolve. Wait for the suds to clear and move to the other steps to fix the Code E4 F8 error.

However, be reminded that using the right type of detergent is important because it plays a role in the operation of your dishwasher and also in errors like Code E4 F8. Ensure you always use a special detergent for automatic dishwashers to avoid foam.

Step 2: Check the Detergent

The second solution to the code E4 F8 error on your Maytag dishwasher is ”check the detergent”. The first step involves confirmation that the appropriate type of detergent is used for the dishwasher.

Specific types of detergent are formulated for use with dishwashers. These detergents are specially formulated to work efficiently without producing lather. Using the wrong dish soap or the wrong kind of dishwasher detergent may result in making too many suds. This can, in turn, lead to a water overflow and trigger the code E4 F8.

When you are experiencing the Code E4 F8 error, you should check the detergent type for this problem. Only use a detergent designed for automatic dishwashers. If you have been using an unsuitable detergent, you will need to change to a suitable one and run a cleaning cycle to see whether the error will be rectified.

Similarly, pay attention to the amount of detergent you are using. Over-sudsing can also be caused by using excessive detergent. Always make sure you use the recommended amount of detergent as specified by the manufacturer on each wash cycle.

To make sure the Code E4 F8 error is not triggered, you need to use only the most effective and the right amount of detergent. If the error persists even with the use of the correct detergent, then you will need to take the next steps for the resolution.

Step 3: Avoid Pre-Washing

The third step for the Code E4 F8 error in your Maytag dishwasher is “Avoid Pre-Washing”. In this step, you ought to avoid the pre-washing of dishes with soap before putting them in the dishwasher.

Before washing dishes, soap can be carried over to the dishes resulting in a film. Soap residue in these dishes, when a wash cycle is run in the dishwasher, can generate additional suds. The suds from these suds can raise the water level and cause Code E4 F8 errors in the dishwasher.

To avoid this issue, it’s only advisable to remove any leftover food, bones, toothpicks, and other hard items from the dishes before loading them into the dishwasher. Pre-washing is no longer required for modern dishwashers because they are built to clean a certain amount of food residue.

Pre-washing should be avoided to prevent excessive suds formation, which may trigger the Code E4 F8 error. In case the issue continues even though you avoid pre-washing, you might have to follow the other steps to resolve the same.

Step 4: Get Rid of the Suds

“Get Rid of the Suds” is the fourth step in resolving the Code E4 F8 error on your Maytag dishwasher. This step involves removing the excess suds from your dishwasher. Here’s how you can do it:

  • Stop the Dishwasher: Stop the dishwasher and check for suds if you see any when you open it.
  • Cancel the Wash Cycle: Turn off the current wash cycle in the dishwasher.
  • Clean Up Any Overflow: Clear up water that has overflowed from your dishwasher due to suds. Do not let water lie on cabinets and floorboards. Pick up the excess liquid with a wet mop.
  • Remove Dishes: Turn off the dishwasher and remove all dishes.
  • Add Cooking Oil: Put ¼ cup of vegetable or other cooking oil inside the dishwasher. The oil will prevent the development of suds.
  • Run a Quick Cycle: Load your dishwasher and run a quick cycle without detergent or dishes. This will allow the soap and suds to run through the dishwasher.
  • Repeat If Necessary: Rerun Quick Cycle until suds have disappeared. Adhere to these steps and you will be in a position to get rid of those suds in your dishwasher and resolve the Code E4 F8 error. In case the problem does not disappear after eliminating the bubbles, one may have to undertake other actions to address the problem.

Step 5: Check the Installation

The fifth solution is Check Installation which involves checking the installation to ensure that it does not cause the Code E4 F8 on your Maytag dishwasher. Here’s what you need to do:

Check the Water Supply: Make sure the water supply to the dishwasher is right. Make sure the connections are tight and there are no leaks by checking.

Check the Float Switch: A float switch is one of the safety features in the dishwasher, that stops it from being overfilled with water. This switch should be connected properly, otherwise, it would result in overfilling, triggering Code E4 F8. Check if the float switch is properly wired.

Check the Drip Tray: The drip tray located at the bottom of your washer is meant to contain any dripping water from the dishwasher. If there is water in the drip tray, this may be a leak somewhere in the dishwasher, thus leading to the Code E4 F8 error. You will need to empty the drip tray once you see water in it.

You can inspect these aspects of your dishwasher’s installation to ensure that they are not responsible for Code E4 F8 errors. It’s best to consult a professional if you detect any problems and not to exacerbate the situation further.
