How to Fix a Dishwasher Soap Dispenser: A Step-by-Step Guide

Understanding the Soap Dispenser Mechanism

Dishwasher Soap Dispenser Mechanism

One of the most important parts of your dishwasher is its soap dispenser. This is where you add your dishwasher detergent before each wash cycle. Without the soap dispenser, your dishes won’t get cleaned properly. However, soap dispenser problems are fairly common and can prevent the soap from dispensing correctly. Here’s what you need to know about understanding the soap dispenser mechanism and how to fix it.

First, it’s important to understand that there are two types of soap dispensers commonly used in dishwashers: the manual release and the automatic release. The manual release dispenser can be opened by pushing down on a latch, while the automatic release dispenser opens during the wash cycle when the latch is triggered by a timer or sensor.

The soap dispenser mechanism consists of four main parts: the release mechanism, the spring, the latch, and the cover. The release mechanism, which can be operated manually or automatically, allows the spring-loaded latch to open and release the soap into the wash cycle. The spring provides the necessary tension to keep the latch closed until the release mechanism is triggered. The latch hooks onto the cover of the soap dispenser to keep the soap inside until it is ready to be dispensed.

One of the most common issues with soap dispenser mechanisms is that the soap won’t dispense properly. This can be caused by a number of factors, including mechanical problems with the release mechanism, issues with the latch, or simply a blockage in the dispenser due to dried-on soap residue.

To fix soap dispenser problems, you can first try cleaning the dispenser thoroughly to remove any soap residue that may be blocking the release mechanism or latch. Simply remove the cover and soak it in warm water with a mild detergent, scrubbing gently with a soft-bristled brush to remove any dirt or buildup. Let the cover air dry completely before reattaching it to the dispenser.

If cleaning the dispenser doesn’t solve the problem, there may be a mechanical issue with the release mechanism or latch. In this case, it may be best to consult a professional or refer to your dishwasher’s manual to troubleshoot and repair the issue.

Overall, understanding the soap dispenser mechanism is key to maintaining a properly functioning dishwasher. By knowing how the mechanism works and how to troubleshoot common problems, you can keep your dishes clean and sparkling with every wash cycle.

Common Causes of Dishwasher Soap Dispenser Malfunction

One of the most frustrating experiences with a dishwasher is discovering that the soap dispenser is not functioning. You load up the dishwasher and eagerly anticipate sparkling clean dishes, only to be disappointed with soapy water swirling around your dishes. Fortunately, this problem can be fixed with a few troubleshooting tips. Below are some common causes of dishwasher soap dispenser malfunction:

1. Incorrect Dishwasher Detergent

One of the common reasons soap dispensers fail is using the wrong detergent. Dishwasher detergents come in different forms, including powder, gel, and tablets. If you use the wrong type of detergent, it can clump and clog the dispenser, making it difficult for the detergent to be released at the proper time. Therefore, it is essential to read the manual and the detergent’s label to confirm that you are using the right product. Be aware that some dishwashers may require a specific brand of detergent, so always check the manual to be sure.

2. Defective Dispenser Lid or Spring

Another significant cause of soap dispenser malfunction is the lid or spring. With regular use, these parts can wear out, causing the dispenser lid to fail to open properly. In some cases, the spring may become detached, making it difficult to open the soap dispenser. If you suspect that a defective lid or spring is causing the problem, you may need to replace it. Consult a professional repair technician or refer to your dishwasher’s manual for guidance on how to replace these parts.

3. Clogged Dispenser

If the dishwasher’s soap dispenser is clogged, the detergent will not be able to flow out properly, leading to a soap dispenser failure. Over time, the dispenser can become clogged by old detergent and soap scum, leaving only a tiny opening for the soap to come out. To clear a clogged dispenser, remove any excess detergent or debris from the dispenser and clean it thoroughly with a brush or toothbrush. If the problem persists, a more intensive cleaning may be necessary, which can be done using vinegar or baking soda.

4. Damaged Dispensing Mechanism

A dishwasher’s dispenser mechanism can also become damaged due to normal wear and tear, leading to soap dispenser malfunction. Damage can occur due to clogs or the dispenser not opening correctly. This can be a challenging problem to spot, as damages may not be obvious to the naked eye, requiring a technician’s expertise. If you suspect that a damaged dispenser mechanism is causing the soap dispenser failure, it is best to consult a professional repair technician as they have the tools and experience needed to repair the problem.

5. Overloading of Dishes

Overloading the dishwasher can lead to the soap dispenser’s failure to open or close correctly, which can cause the detergent to remain stuck inside the dispenser. To prevent this, it’s important to adhere to the manufacturer’s loading guidelines. This will prevent overcrowding and ensure proper detergent and water distribution, allow the dishwasher to function properly, and reduce the likelihood of soap dispenser malfunction.

In conclusion, a dishwasher soap dispenser malfunction can be a frustrating experience, but it is fixable. The above causes can act alone or in combination, leading to the failure of the soap dispenser. To avoid this, it is vital to ensure that you are using the correct detergent, loading the dishwasher correctly, and keeping a regular maintenance routine to prevent soap scum buildup.

Tools Required for Fixing a Dishwasher Soap Dispenser


When it comes to fixing a dishwasher soap dispenser, there are some basic tools that you will need to have on hand. These tools will help you to remove the old soap dispenser and replace it with a new one into your dishwashing system. Here we have listed below some of the most essential tools that you’ll require while fixing your dishwasher soap dispenser.

Screwdriver Set


A screwdriver is an essential tool for repairing the dishwasher soap dispenser. It’s important to ensure that you have a set of screwdrivers that include both the Phillips and flathead ones. The Phillips screwdriver is generally the most commonly used tool as many of the dishwasher components are held in place with Phillips screws. The flathead screwdriver is useful for prying, separating components or for releasing clips that hold the dishwasher soap dispenser in place.



A multimeter is another necessary tool you should have as you’ll need to use it to check the continuity of electrical connections around the dishwasher soap dispenser. It’s an electronic device that measures voltage, current, and resistance and will help you determine if there is any problem with the electrical connections in the dishwasher soap dispenser or any other component.



Pliers can be used to grip, hold objects, as well as for cutting wires. They are very useful in many situations related to dishwasher soap dispenser repair, especially when clips or wires need to be removed or snapped back into place. Pliers are also useful when working with tight spaces and reaching inaccessible areas.

Wrench Set

A wrench set is another critical tool required for fixing a dishwasher soap dispenser. You’ll need to have the right wrench set that matches the size of the nuts, bolts, and screws in the dishwasher soap dispenser. Wrenches can be used to tighten and loosen screws and bolts, especially the ones holding the dishwasher inner panel, which may require a bit of extra force.



Finally, you need something in which to keep all your tools handy. A toolbox is an excellent option, whether having a portable one or a stationary box that can be kept in the workspace. This way, everything is kept organized and in one place, and it is easy to find what you need when you’re working on fixing the dishwasher soap dispenser.

While fixing your dishwasher soap dispenser might seem like a daunting task, it can be less overwhelming if you have the right tools and knowledge. By having the right tools to hand, you can fix your dishwasher soap dispenser and ensure it runs smoothly and efficiently for many years.

If your soap dispenser still isn’t working after you’ve cleaned it and checked the dishwasher’s settings, the problem may be with the dispenser switch. The dispenser switch is responsible for telling the dishwasher when to release soap during the wash cycle.

To replace the dispenser switch, you’ll need to locate the switch inside the dishwasher. This switch is usually located behind the dishwasher’s control panel. Refer to your dishwasher’s manual for instructions on how to remove the control panel and access the switch.

Once you’ve located the dispenser switch, remove the old switch and replace it with a new one. Make sure that the new switch is installed correctly and that all wires are properly connected.

Tips for Preventing Future Dishwasher Soap Dispenser Problems

Having a dishwasher that works well is essential for any modern home, but unfortunately, it’s not uncommon for the dishwasher soap dispenser to start giving problems over time. Many homeowners have complained of soap dispensers that don’t open, opening too early, or never opening at all. While these issues can be frustrating, the good news is that there are some things you can do to prevent them from happening in the first place. Here are some tips for preventing future dishwasher soap dispenser problems:

1. Use the Right Soap

One of the main causes of dishwasher soap dispenser problems is using the wrong type of soap. Always use dishwasher soap and not liquid dish soap, hand soap or any other type of detergent. Liquid dish soap or hand soap will create too much sudsing and can cause the dispenser door to be unable to open. Buying the right kind of detergent can save you significant frustration and unnecessary repairs.

2. Clean the Dispenser Regularly

Another important tip for preventing future dishwasher soap dispenser problems is to clean the dispenser regularly. Soap residue, minerals, and other particles can build up in the dispenser over time, blocking the door from opening or causing it to stick. To clean your dispenser, remove it from the dishwasher and rinse it under warm water. You can also use a soft brush or toothbrush to scrape off any mineral build-up in the dispenser. This should be done regularly to avoid any build-ups that may cause blockages and cause the dispenser to malfunction.

3. Load Your Dishwasher Carefully

How you load your dishwasher can greatly affect the performance of the dishwasher soap dispenser. Overloading the dishwasher can block the soap dispenser’s door from opening properly, while also affecting the quality of cleaning. On the other hand, underloading your dishwasher can cause the water to spray constantly on the detergent and cause it to be washed away before it has a chance to dissolve. Properly loading the dishwasher can help avoid any blockages that can occur in the soap dispenser.

4. Check Your Dishwasher’s Hinge

Another factor that can affect your dishwasher soap dispenser is a weak or broken hinge. If the hinge holding the soap dispenser door is worn out, the soap dispenser may not open at the right time, allowing water to flow into the dispenser instead of the dishes. Make sure to inspect the hinge regularly to ensure that there are no damages that may cause any issues. Repairing or replacing a faulty hinge can go a long way in ensuring that your dishwasher works excellently.

5. Avoid Overusing Rinse Aid

Rinse aid is designed to assist in the drying process and keep your dishes looking sparkling clean. However, overdoing it can cause the rinse aid to foam and clog your dishwasher soap dispenser, leaving spots on your dishes. Make sure to use the recommended amount of rinse aid and don’t overfill the dispenser container. Using too much can cause the dispenser to clog, and this can lead to repairs and decreased efficiency of your dishwasher.

In conclusion, implementing these simple tips can go a long way in preventing future dishwasher soap dispenser problems. Regular cleaning and maintenance, proper loading, checking the hinges, as well as using the right detergent and avoiding overusing rinse aid can help ensure that your dishwasher works well. Following these tips will save you the headache of having to fix or replace your dispenser, and the frustration of having dishes that are not properly cleaned.
