4 Reasons Your LG Refrigerator Water Filter Won’t Go in!
Having your LG refrigerator provide purified water is one of the perks of a water filter.
As the proud owner of such an appliance, you can depend on something other than drinking water sources whose purity you are unsure of. Examples are bottled or tap water.
To keep your water clean, you have to change it regularly. However installing a new water filter seems like an easy enough task, but what happens when you need help getting it right?
Your water filter won’t go in because it cannot withstand the waiting water pressure. But you can quickly solve it by regulating the water pressure in your LG refrigerator water lines. There could also be damage to the water filter. If you have handled it roughly, some of its parts could be broken or misshapen.
In this article, I will point out why an installation is not working, the mistakes you might be making, and how to avoid them, among many others.
Why Is My LG Refrigerator Water Filter Not Going In?
High water pressure, water filter size, and flawed methods of fixing it can prevent the filter from going in. Sometimes, you might be able to get it in, but it still needs to stay in place.
More water pressure could be why your filter isn’t going in, just as well as you getting the filter measurements wrong.
You can determine why your water filter isn’t going in through the detailed explanation below.
#1. High Water Pressure
The fault might have nothing to do with your LG refrigerator water filter and everything to do with the water pressure in your refrigerator.
Turning off the water supply when fixing the water filter is essential; however, that is not where it ends. If the water pressure remains the same, your water filter will not go in or stay in.
According to simple physics, high water pressure pushes a lot of force against the water filter.
This force is usually too high for the water filter to withstand, so getting your filter in position is challenging.
High water pressure could unlock its holding mechanisms, throw the water filter out and leave your kitchen floor flooded.
Also, a partially shut locking mechanism inside the water filter could prevent it from going into place.
Ideally, this locking mechanism should be fully open but stay half shut when exposed to high pressure.
#2. Internal Damage
A part of your LG water filter could have broken or snapped during handling. If this is the case, you will have trouble getting your water filter into position.
A damaged water filter only does a little, even if you get it in place, because it will have difficulty correctly passing clean water.
#3. Wrong Installation Method
Nothing could be wrong with your water filter and pressure. You could just be fixing the water filter wrong. You could be screwing it all in.
You can resolve the issue by installing the water filter correctly from the installation manuals to guides.
The table below points out the common installation mistakes you might be making and the correct way to do them.
| Mistakes | Corrections |
|---|---|
| Fixing the water filter backward. | Turn it clockwise to avoid damaging the cartridge end cap. |
| Removing the O-rings. | Leave the O-rings in place for a tight hold. |
| Removing the protective cap. | Leave the cap on for a firm seal. |
| You threw the knob from the previous filter away. | It is reusable. Fix the new filter with it. |
#4. Wrong Filter Size
Your water filter won’t go in because it needs to be the right size for your refrigerator.
Although generic water filters are cheaper than brand water filters, buying cheap ones might make you buy twice.
LG refrigerator water filters are built in a specific way to fit LG refrigerators, so you have to purchase the original brand replacements.
Its generic counterparts could be too wide or too thin—a few differences in millimeters.
Before you order a new water filter, take the correct measurements of your old LG water filter and find a replacement with the exact match.
This way, you can easily get your water filter in during installation.
How Do You Put an LG Refrigerator Water Filter Back In?
You can put your water filter back in by repositioning it and carefully pressing it. Putting the water filter back into your LG fridge is easy, and you can do it yourself.
First, regulate your water pressure, so it does not pop back out. To do this, locate the water inlet valve and turn it clockwise.
Run a nearby water outlet to tell when the flow and water pressure decrease. Continue to turn it until the pressure is optimal.
Get a monkey wrench if you find it difficult to turn the valve with your hand. You can also call a technician to put the water filter in.
It also helps to change the water filter, as it could be in the wrong size.
What Do I Do If My LG Fridge Water Filter Is Stuck?
Reduce the water pressure on your water filter. Excess water pressure in the water line can keep the filter in place and prevent you from getting it out.
To reduce the stress, close and reopen the compartment door to the water filter. Next, unplug the LG refrigerator from its outlet and drain some water from the water line.
You can run the water dispenser to let out some water for about a minute. It will decrease the pressure in the water line and make removing the water filter easier.
Remove the fridge’s front bottom grille to get your stuck water filter out.
You can find instructions on removing the front grille in an installation manual with the refrigerator. You should be able to access the filter cap after.
Then, wrap a cloth around the filter cap to prevent tool damage. With a pair of pliers, grab the filter cap through the cloth and carefully turn it to the side.
Do not apply too much pressure to the fragile bits, as it could damage your water filter or the water system at worst. Now, pull the water filter out entirely with the pliers.
Can You Replace the LG Fridge Water Filter Without Turning Off the Water?
No, you should turn the water off before attempting to replace the water filter in your LG refrigerator.
Turning the water off is crucial to prevent it from coming through the water filter while trying to replace it.
Turning off the water also decreases the water pressure in the pipes, and you need that when replacing a water filter.
However, turning off the water supply to your entire kitchen or house is optional when replacing your water filter. Doing that could be inconvenient.
Instead, turn off the water supply to the refrigerator only. Then, you can easily unscrew the old filter and fix it with the new one.
A convenient development to the design of recent water filters is that once you unscrew it, the water supply shuts off automatically.
In this case, you do not have to worry about manually turning the water inlet valve to shut the water off.
Why Is My LG Fridge Water Filter Sputtering?
Your water filter could be spluttering because of excess air in the water pipes. Other reasons include using the wrong water filter and a problem with the water valves.
A sputtering water filter could affect the water flow from the outlet if it lingers.
#1. Excess Air
Too much air in the water lines is the most common cause of sputtering noises from the water filter. Tiny cracks and spaces in the pipes can cause air pockets into the water supply.
These air bubbles lead to sputters. An easy fix is to open the dispenser to let the water run freely. Continuously using the water filter will eventually release the trapped air bubbles.
However, if the sputtering continues, the air could be from the main water supply. Call a technician to inspect the water pipes and seal off the cracks.
#2. Blocked Water Inlet Valve
You can pinpoint the sputtering from your LG fridge’s back. The fault isn’t from the water filter but the water inlet valve.
Particles, bent pipes, or a broken component could block the free flow of water and lead to sputtering.
#3. Incompatible Water Filter
Your water filter may need to fit better into your refrigerator. If you recently changed the type or size of water filter you use for your LG refrigerator, it could cause sputtering noise.
Ideally, you should use a water filter recommended by your refrigerator brand as a replacement.
But if you want a generic water filter, ensure you get the measurements right. Better yet, take the old water filter to the store to get the perfect replacement.
FAQs
#1. Should I Discard the Colored Cap Covering the Water Filter’s End?
No, the plastic or metal cap does not permanently connect to the filter, so pull it off the old filter.
When fixing another water filter, you can put it on the new one. You don’t have to buy a new cap.
#2. What Is the Typical Price of a Refrigerator Water Filter?
The typical price of refrigerator water filters ranges from 60 USD to 100 USD. This price varies according to the water filter’s brand, size, or quality.
#3. Can You Run an LG Refrigerator Without a Water Filter?
Yes, you can. All you have to do is to install the bypass plug. This plug replaces the water filter in your LG refrigerator.
#4. What Happens If I Don’t Replace the LG Refrigerator Water Filter?
You may end up drinking water filled with harmful bacteria. A water filter left unchanged also accumulate toxic chemicals and dirt particles. Eventually, this dangerous cocktail affects taste.
