How to Get Rid of Soap Suds in Dishwasher

Soap suds are bubbles or soap foam that result during the dishwasher cycle. You might think they look amazing, but this bubbly mess can be quite troublesome to clean up once it has escaped the dishwasher door and landed on your kitchen floor.  

Suppose you have accidentally put dish soap into your dishwasher or used the wrong dishwasher detergent for your dishwasher. In that case, you might be dealing with an avalanche of soap suds that won’t just quit when turning off the dishwasher. 

Remember, prevention is key. Simply knowing the right way to use dishwasher detergents can save you from your next foam party. You have the power to avoid this situation in the future. 

Rest assured, there are effective solutions to this bubbly overflow. Take a look at the tips below to learn how to get rid of soap suds in your dishwasher and regain control of your kitchen. 

Why do soap suds happen in the dishwasher? 

Before we tell you how to get rid of soap suds, it is essential to understand why they occur. The three main reasons for a soapy mess in a dishwasher include: 

Using dish soap in the dishwasher results in thick, sudsy foam that will eventually overflow through the dishwasher door. This happens because, unlike detergents that use enzymes to clean dishes, dish soap relies on suds and bubbles for cleaning.

Hard water, which contains high levels of minerals like calcium and magnesium carbonates, can also cause soap suds by preventing the dishwasher detergent from dissolving properly—leading to the detergent residue that turns into soap suds during the wash cycle.

To prevent another soapy situation in your kitchen, it is best to choose dishwasher tablets, such as Quantum Ultimate All-In-One. These tablets provide a consistent and measured amount of detergent, eliminating guesswork and ensuring optimal cleaning results.

To minimize the impact of hard water, use Finish Dishwasher Salt as an additive. It flows through the softener unit before being drained with the wastewater and provides sodium for the dishwasher’s ‘ion exchange resins’ that are in the softener. When regenerated by the sodium, it works to attract and trap the magnesium and calcium ions that cause hard water.

Now that you are familiar with the most common reasons for soap suds in dishwashers, let’s explore how you can get rid of soap suds and restore your appliance functionality.

How to get rid of soap suds in dishwasher? 

Here are the steps you can take to eliminate soap suds in your dishwasher:

  1. As soon as you notice excessive suds, stop the dishwasher wash cycle immediately to prevent more suds from forming, and begin the draining process. 

  2. Before addressing the suds in your dishwasher, swiftly clean up any spilled soap and water on your kitchen floor, open the dishwasher door, and take out all the dishes.

  3. Manually remove excess suds from the dishwasher using a sponge, cloth, or paper towel. Regularly wring out the sponge or cloth to ensure effective removal of the collected suds.

  4. Now that your dishwasher is empty, it's time to clean its interior. Begin by wiping down the dishwasher tub. Once the visible suds are removed, fill a small bowl with water and gradually pour it into the tub to rinse away any remaining soap. 

  5. Repeat this process several times until no soap bubbles form when the water hits the dishwasher floor. After each water refill, use your towel to wipe off any new soap suds. 

  6. Skipping the rinsing step will leave soap residue in your dishwasher, leading to another sudsy mess during the next wash cycle.

  7. Complete the cleaning process by initiating a rinse cycle. It helps determine if any soap residue remains in the dishwasher; if so, additional suds will appear during the rinse cycle. Additionally, if your initial cleaning was thorough, the rinse cycle should eliminate any lingering residue. 


After the cycle concludes and you're certain that your dishwasher is free of soap suds, reload it and fill the detergent dispenser with Finish Quantum Ultimate All-In-One tablets. This dishwasher detergent provides the ultimate cleaning experience for your dishes and gives them a diamond shine.
