How to change a water filter on a lg refrigerator

Have you noticed that the water filter light on your LG LMSW27626S French 4 Door Refrigerator is flashing? Does the water or ice dispensed from the refrigerator no longer seem fresh? If you answered “yes” to either of those questions, it’s time to use this guide to change the water filter.

Water filters help to purify tap water by removing contaminants. They also help to improve the smell and taste of the water and ice dispensed from the refrigerator. The water filter should be replaced about every six months, depending on how much or little you use the water and ice dispenser.

Before beginning, be sure to remove any objects surrounding the water filter housing to allow for easy access.

The following instructions will guide you in replacing your water filter.

• Find a replacement water filter based on the model number for your fridge.

• You can also bring your old water filter to a store to get a suitable replacement that way.

• For the best result, it's best to buy the original filter that was made for the fridge as opposed to an aftermarket water filter.

• Remove the water filter from the box .

• Remove the cap from the water filter.

• Open the water filter bay in the top left corner of the fridge.

• Remove the existing water filter inside. Or, if your fridge doesn't yet have a water filter, remove the green cap instead.

• Angle the receiver in the fridge downward so that the filter is easy to plug in.

• Firmly press the water filter into the receiver until it is snug and attached.

• If the water filter falls out once you let go, you simply need to press harder into the receiver.



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

Thewater filterin 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.

Once you open it, you’ll have access to thewater filteryou’re about to change.

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 newLG fridgewater filterout 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 yourLG fridgeis 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 MyLG FridgeNot Cold?

You’ll surely want to have a drink after installing your newwater 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 yourLG fridgewater dispenser.
