If you own an LG dishwasher, you probably know how efficient and reliable it is at cleaning your dishes. However, to ensure that your dishwasher continues to perform at its best, it’s essential to properly maintain it. One crucial aspect of dishwasher maintenance is filling up the rinse aid dispenser. Rinse aid helps improve drying performance, prevents water spots, and ensures your dishes come out sparkling clean. In this article, we’ll walk you through the process of filling up rinse aid in your LG dishwasher, step by step.

Why Use Rinse Aid in Your LG Dishwasher?

Before we delve into the process of filling up rinse aid, let’s understand why it’s an essential component of dishwasher maintenance. Rinse aid plays a vital role in the drying process, particularly in modern dishwashers like LG models. When your dishwasher’s cleaning cycle is complete, a final rinse is done to remove any remaining detergent and food particles. Rinse aid helps in this final rinse by reducing the surface tension of water and allowing it to flow off your dishes more easily.

Without rinse aid, water droplets can form on your dishes, and when they dry, they leave behind unsightly water spots and streaks. These spots can be particularly annoying on glassware, leaving a film that’s hard to remove. By using rinse aid, you can ensure that your dishes come out spot-free and dry, saving you time and effort when unloading your dishwasher.

Step-by-Step Guide to Fill Up Rinse Aid in LG Dishwasher

Filling up rinse aid in your LG dishwasher is a straightforward process, and it should only take a few minutes. Here’s a step-by-step guide to help you through it:

  1. Locate the Rinse Aid Dispenser: Open your LG dishwasher and look inside the door. You should find the rinse aid dispenser on the inner side of the door, usually near the center or towards the right-hand side. It is a small compartment with a flip-up lid.
  2. Check Rinse Aid Level: Before adding more rinse aid, it’s a good idea to check the current level. If the rinse aid indicator is low or empty, it’s time for a refill.
  3. Open the Rinse Aid Compartment: Flip up the lid of the rinse aid compartment to reveal the opening where you will pour the rinse aid.
  4. Use a Funnel (Optional): Rinse aid is a liquid, and to avoid spills, you may want to use a funnel to pour it into the compartment.
  5. Pour the Rinse Aid: Carefully pour the rinse aid into the compartment until it reaches the “Max” or “Full” level indicator. Avoid overfilling, as this can cause issues with dispensing and may lead to leaks.
  6. Close the Lid: Once the rinse aid is filled, gently close the compartment’s lid.
  7. Wipe Off Any Spills: In case there were any spills during the filling process, wipe them off to prevent any potential drips during the dishwasher’s operation.
  8. Select Rinse Aid Setting (If Available): Some LG dishwasher models allow you to adjust the rinse aid dosage. Check your dishwasher’s manual for information on how to do this if applicable.
  9. Replace Detergent Cap: If you removed the detergent cap before, be sure to place it back securely.
  10. Run Your Dishwasher: With the rinse aid properly filled, you’re now ready to run your dishwasher as usual. Enjoy spotless and dry dishes!


1. How often should I fill up the rinse aid in my LG dishwasher?

The frequency of filling up rinse aid depends on your dishwasher’s usage and the hardness of your water. As a general guideline, check the rinse aid level every month and refill it when it’s low.

2. Can I use any rinse aid in my LG dishwasher?

While some dishwasher manufacturers recommend using specific rinse aid brands, you can generally use any rinse aid in your LG dishwasher. However, for optimal results and to prevent any potential damage, it’s best to use a rinse aid that is suitable for your dishwasher model.

3. My dishes still have water spots even with rinse aid. What could be the issue?

If you notice water spots on your dishes even with rinse aid, it could be due to a few reasons. Firstly, check if you’ve filled up the rinse aid correctly and adjust the dosage if your dishwasher allows it. Secondly, make sure you’re using the appropriate rinse aid for your water hardness level. If the problem persists, consider checking your dishwasher’s spray arm and cleaning it if necessary.

4. Can I use vinegar as a substitute for rinse aid?

Vinegar is a natural alternative to rinse aid and can help in reducing water spots. However, it may not provide the same level of effectiveness as a dedicated rinse aid, especially when it comes to improving drying performance.

5. Is rinse aid necessary if I use all-in-one dishwasher detergent tablets?

While all-in-one dishwasher detergent tablets include rinse aid components, using a separate rinse aid can still enhance the drying performance and prevent water spots further.

6. How do I know if my LG dishwasher has run out of rinse aid?

Most LG dishwashers have a rinse aid indicator on the control panel or inside the door. When the rinse aid level is low or empty, the indicator will typically light up to alert you.

7. Can I fill the rinse aid compartment to the top?

It’s essential not to overfill the rinse aid compartment, as this can lead to leaks and dispensing issues. Fill it up to the “Max” or “Full” level indicator.

8. Are there any eco-friendly rinse aid options available?

Yes, some brands offer eco-friendly rinse aid options that are biodegradable and free from harsh chemicals. Check the product labels for eco-friendly certifications or look for natural ingredients like plant-based surfactants.
