How to Change the Water Filter in an LG Refrigerator

Refrigerators have become undoubtedly one of the most important appliances in modern-day kitchens. They not only keep our food chilled but they help to keep it fresher for longer too. One of the best parts of modern fridges is the water and ice dispensers. There is nothing better than being able to fill a glass with crushed ice and cool water at the press of a button on a hot day.

While it is a very low-maintenance luxury, there are a few things you need to do on a semi-regular basis to ensure fresh, great-tasting, clean water. Changing your water filter is one of them, and it’s an easy, quick job you can do yourself with our guide to changing your LG fridge water filter.

Before you start, there are a few things you will need.

When do you know that it’s time to replace your LG fridge filter?

While it depends on how often you use your fridge’s water functions, LG water filters should be replaced every 6 months (or sooner). Thankfully, some models have a filter change alert that alerts you when it’s time to replace the filter.

If your fridge doesn’t have an indicator, then there are a few signs you should watch out for. Slower than normal water flow is one of them; this is caused by a build-up in the water filter. This could signal it is time for a change.

Another common sign is if there is an unpleasant odor or a funny taste in your water.

Why should you choose genuine LG water filters?

There are a lot of reasons you should always use a genuine LG filter. For starters, they filter out many contaminants such as pesticides, lead, iron, and chlorine. They remove 97% of benzene, 99% of atrazine, and almost all mercury and lead, which can be dangerous for your health. They help to provide cleaner, fresher, and better-tasting water and ice. They are the correct design for your fridge model, while third-party filters may cause damage not covered under the LG warranty if used.

Remember to turn off the water supply first and dispense water until it no longer comes out of the dispenser before you go to change the water filter.

If your water filter is located on the door like on these models, follow these simple instructions:

Remove the old filter

Start by lifting up and removing the lower door bin. Next, you need to swing the right end of the water filter out of the compartment. After that, rotate the filter counter-clockwise to remove it from the filter head.

Install the new water filter

Don’t forget to remove your new filter from the packaging; this includes the protective cover on the rubber o-rings. Place your new filter into the filter head. Then rotate it clockwise until the arrow on the new filter lines up with the arrow on the filter head. Now you can swing the filter back into the compartment.

Remove trapped air

The final step is to reset the water filter indicator light. You can do this by holding down the water filter button next to it for about 3 seconds.
