How To Change/Reset Water Filter In LG Refrigerator?

Nothing beats the convenience of getting water from your LG fridge’s water dispenser. Still, that convenience does require a bit of maintenance on your part, which is to change the water filter every 6 months.

You can change the water filter by locating it in the fridge compartment. You won’t need tools to open the holder and remove the existing filter. Then, install a genuine and compatible LG water filter into the holder. Flush at least 2.5 gallons of water through the new filter before using the dispenser.

The change and reset process is very straightforward, so don’t worry if you haven’t done it before. This guide will walk you through every step of the way.

How Do You Change The Water Filter On An LG Refrigerator?

Changing the water filter on an LG fridge is pretty straightforward. You can even get the job done in just a few steps.

But before you start, shut off the water supply at the back of your fridge. The shutoff valve should be fully closed to ensure no water enters the appliance while you’re changing the filter.

Next, press the dispenser lever to drain all water from the appliance. Keep pressing the lever until no more water comes out.

Lastly, find the filter in your refrigerator model and lay a towel down underneath it. 

You’ll typically find it on the top of the fridge compartment close to the rear left-hand corner. Other models might have their filters concealed inside one of their doors. But, again, you should refer to the user manual to see where yours is located.

Once you’ve completed the preparations, you can follow these 5 quick steps to change the water filter in your LG fridge:

Step 1: Open Filter Holder Or Cover

The water filter in your refrigerator is never left exposed. Instead, it’ll have a holder and a cover to conceal it, helping the filter blend in with the rest of your fridge interior.

At this point, you’ve located the filter holder and prepared a towel underneath it. So, the first step is to pop that filter cover open. You can do so by hand, as no tools are necessary for any step of this process.

Step 2: Release Filter Pivot And Remove

Next, you’ll need to get the used filter out of that holder. 

Firstly, grab the filter and pivot it out from its holder. So, for example, if your filter is at the compartment’s top, you’ll be pivoting it downwards.

Then, you can pull the filter out of its position. Be careful when you do this, as any leftover water might drip out. Thankfully, you’ve already prepared a cloth underneath it earlier.

With the filter removed, you can wipe the area inside its holder to remove any dirt or other buildups.

Step 3: Install The New Filter

The next step is to take your new LG fridge water filter out of its packaging. Then, you can install it in the filter holder in the opposite sequence you followed in Step 2.

So, push the filter into place. Once it fits snuggly, pivot the filter upwards so it sits in the holder.

You can close the filter cover when you’re confident that everything fits correctly and the filter isn’t loose.

Step 4: Flush The Filter

The job doesn’t end after you’ve installed a new filter. There are still two crucial steps you must take.

Firstly, you’ll want to flush the filter to remove any carbon and air bubbles trapped in the water line. These things can prevent water from flowing smoothly later, so it’s best to get the flushing done early.

Besides that, flushing the filter helps eliminate that ‘new filter taste’ you’ll find in the water.

You can begin the flushing process by turning the water supply back on behind the fridge (you shut that off earlier). Then, keep the water dispenser lever pressed to flush at least 2.5 gallons of water through the filter.

Doing that will take approximately 5 minutes to complete. So, you can simplify the process by flushing that water into a large container like a bucket.

Step 5: Reset The Filter Indicator

There’s a strong chance that you replaced the filter because its indicator was illuminated on the control panel. Now that you’ve completed the replacement, you’ll want to reset that indicator, so it turns off.

How Do I Reset My LG Filter Indicator?

Resetting the filter indicator on your LG fridge is incredibly simple. Press and hold the button on the control panel until it turns off. 

Typically, you’ll have to hold the button for 3 seconds.

You can be sure of the duration that applies to your model by checking the control panel. The duration is printed on the filter indicator button.

Why Is The Water In My LG Fridge Not Cold?

You’ll surely want to have a drink after installing your new water filter. You can certainly do that, but don’t be surprised when it doesn’t dispense the cold water you’re expecting.

Here’s why the water coming from the dispenser is warm after a filter change:

#1 The Water Reservoir Is Empty

Firstly, you must understand that the water reservoir no longer has chilled water. 

The reservoir is small and only designed to hold 1-2 cups of cold water at a time.

Secondly, you drained the reservoir before you began replacing the filter.

#2 The Water Is Directly From The Water Line

When the reservoir is empty, and you push the dispenser lever, the water you get is from the water line behind your fridge. Then, of course, the water passes through the new filter and is safe to drink. 

However, its temperature still wouldn’t have changed. So instead, the water passes through to the dispenser and down into your cup.

#3 The Fridge Hasn’t Had Time To Chill The Water

Overall, the water you get isn’t cold after a filter change because it hasn’t had enough time to cool down.

An empty reservoir will need at least 6 hours to refill with water and chill it down. After that time, you can begin to enjoy cold water directly from your LG fridge water dispenser.

Can I Use A Generic Water Filter In My LG Refrigerator?

No, you cannot use a generic water filter in your LG fridge. Instead, you should only use a genuine LG water filter that’s designed specifically for use with your fridge model.

  1. Took a trip and turned off water to the house. Sink tap water was used after that so, it drained the line. Once water was turned back on the water on fridge was used to fill container. Walked away and a bit later noticed the light was on at the water dispenser and water started shooting out. Tried to stop it with the lever in front but, no success. Water shot out all over the wood floor. Wound up turning the water to fridge off. Any Suggestion’s on fixing?
