Title: LG Dishwasher LDF8072ST Dispenser Not Dispensing Soap: A Troubleshooting Guide

Have you ever encountered the frustrating situation where your LG dishwasher, specifically the LDF8072ST model, fails to dispense soap during a wash cycle? Don’t worry; you’re not alone. This common issue can be caused by various factors, from a faulty dispenser to incorrect loading techniques. In this comprehensive troubleshooting guide, we will explore the possible reasons behind this problem and provide you with practical solutions to get your dishwasher back to its soap-dispensing glory.

1. Understanding the Dishwasher Dispenser System

Before diving into troubleshooting, let’s first understand how the dishwasher dispenser system works. The dispenser is responsible for releasing detergent at the appropriate time during the wash cycle. It typically consists of a detergent compartment, release mechanism, and a rinse aid dispenser for added shine.

2. Checking for Dispenser Blockages

One of the most common reasons for soap not being dispensed is a blockage in the dispenser. Start by inspecting the detergent compartment for any clogs or residue buildup. Use a sponge or cloth to clean it thoroughly, ensuring there are no obstructions that could hinder the soap’s flow.

3. Verifying Proper Detergent Usage

Using the correct type and amount of detergent is crucial for effective cleaning and soap dispensing. Make sure you are using a dishwasher-specific detergent and following the manufacturer’s guidelines for dosage. Using too much or the wrong type of detergent can lead to dispenser issues.

4. Loading Techniques and Dishwasher Overloading

Improper loading techniques and overloading the dishwasher can interfere with the dispenser’s functionality. Ensure that dishes, utensils, and cookware are arranged properly, allowing the water and detergent to reach all items. Avoid overcrowding the dishwasher, as it can obstruct the dispenser’s opening and prevent soap from being released.

5. Checking the Dispenser Door

Inspect the dispenser door for any damage or misalignment. A faulty door can prevent it from opening during the wash cycle, resulting in soap not being dispensed. If you notice any issues, such as cracks or loose hinges, consider replacing the dispenser door.

6. Testing the Dispenser Mechanism

To determine if the dispenser mechanism is faulty, you can perform a simple test. Start a wash cycle without any dishes and observe the dispenser during the appropriate stage. If the door fails to open or if the soap remains stuck, it’s likely that the dispenser mechanism needs to be repaired or replaced.

7. Checking Water Temperature

The water temperature plays a crucial role in detergent activation and proper soap dispensing. Ensure that your dishwasher’s water temperature is set to the recommended level. If the water is too cold, the detergent may not dissolve properly, leading to dispenser issues.

8. Inspecting Water Inlet Valve

A malfunctioning water inlet valve can affect the water pressure and temperature inside the dishwasher, consequently impacting the soap’s dispensing process. Inspect the valve for any signs of damage or blockages. If necessary, consider replacing it to ensure optimal dishwasher performance.

9. Rinse Aid Dispenser

Apart from the detergent compartment, your dishwasher may also have a rinse aid dispenser. This dispenser helps in preventing water spots and enhancing drying performance. Check if the rinse aid compartment is filled adequately and adjust the dosage if necessary. A lack of rinse aid can sometimes lead to soap dispensing issues.

10. Contacting LG Customer Support

If you have exhausted all the troubleshooting steps and your LG dishwasher’s soap dispenser still refuses to cooperate, it may be time to seek professional assistance. Reach out to LG’s customer support for further guidance and potential repair options.


Dealing with a dishwasher soap dispenser that refuses to dispense soap can be frustrating, but with the right troubleshooting steps, you can resolve the issue and get your LG LDF8072ST dishwasher back to optimal performance. Remember to check for blockages, use the correct detergent, follow proper loading techniques, and inspect the dispenser mechanism. Don’t hesitate to seek professional help if needed. Happy dishwashing!
