Replacing the LG Fridge Water Filter in LG Refrigerators – LT800P, LT1000P

Changing the water filter in your LG fridge, whether an LT1000P or LT800P beside the door, is straightforward, ensuring your water stays clean and fresh. For this, I recommend replacing the water filter every six months to keep it in optimal condition. Here’s a step-by-step guide to it. 

Step 1: Take the Filter Out

Start with taking the filter out by elevating and extracting the lower bin. You can find it easily since the LG water filter is mainly beside the refrigerator door. It will have a release button or a marked cover as well. 

Once located, I suggest dispensing water to relieve pressure before changing the filter.

When you finish this, elevate and extract the lower door bin.

To remove the water filter from the filter head, swing its right end out of the compartment, then grab it and turn it counterclockwise.

Step 2: Time to Replace the Filters

Once done with the nitty-gritty steps, I took the new filter and protective cover off the rubber o-rings from the packing. You can also check the user manual, as some filters might need soaking (mine did too).

Then, insert the new filter in the filter head and twist it clockwise until it locks into place or the arrows align on the two filters. 

Step 3: Expel Out Any Trapped Air

Return the lower-door bin to its starting location. Dispense water to clear the system of impurities, loose charcoal, and trapped air. To do this, depress and simultaneously release the dispenser pad for 30 seconds on and 60 seconds off. 

Step 4: Finally, Reset the Water Filter Identification

When you’ve successfully replaced the filter, press and hold the water filter button adjacent to the light for approximately three seconds to reset the water filter indication light.

How To Replace LG Water Filter (Top Interior) For LT1000P, LT800P, LT700P 

Now moving on to filter replacement for the top interior, follow the steps enlisted below:

Step 1: Take the Top Shelf off

Locate the filter compartments at the top left shelf of your LG French door refrigerator if you have LT1000P, LT800P, and LT700P. But, before replacing it, I suggest closing the water valve to minimize spills and ensure a cleaner process. Then, remove the filter in an anti-clockwise direction; it may be a simple slide or a latch. 

Step 2: Installing the New Filter

Remove the new filter from the packing and install it with the filter tabs in the horizontal position. After inserting the filter into the filter mount, rotate the water filter downward until it locks. Once done, tightly shut the cover to secure it in place.

Step 3: Turn on the Water Supply

Restore the water supply, and anticipate any air bubbles by dispensing a few cups. You need to do this slowly and gently to avoid any remaining water splashes. After this, run a final check for leaks. 

How to Remove and Replace Seamless LG LT900X3 Water Filter?

Upon my DIY learning, I also found an easy way to deal with the LG’s sole model. Here’s how to change the LT900X3 water filter. 

Step 1: Locate the Filter Compartment

The first main thing is to understand that tracking down the filter compartment is elementary. So, you must also do this. For the LT900X3, it’s often in the rear interior of the fridge. However, depending on your fridge model, it might require pulling out a drawer or removing a panel.

Step 2: Get rid of the Old Filter

Now, get ready to engage the release mechanism unique to the LT900X3. Turn the handle 90 degrees to the left to replace the water filter. To remove it, pull the handle forward. Depending on your fridge’s design, this might involve pushing the push button, pulling, or twisting. Therefore, apply steady pressure to disconnect the old filter.

Step 3: Installing the New Water Filter

Take the new filter out of its packaging. Place and replace the water filter while holding the handle upright. Rotate the handle ninety degrees to the right to secure it in its position. 

A Pro’s Guide On How to Change Water Filter In LG Refrigerator: LT500P, LT600P

Now, it’s time to talk about the last two models on my list. Here’s how to replace the water filter (LT600P and LT500P):

Step 1: Locate the Filter Compartment

Find the filter housing in the upper-right interior of the LG French door refrigerator. It might be behind a labeled cover or within a compartment. Take note of any clips or release mechanisms. I took some pictures beforehand, and trust me it helped in the long run.

Step 2: Remove the Filter

For both the LT600P and LT500P, a simple twist counterclockwise will release the old filter. If it’s tight, use gentle but firm pressure. Have a towel ready to catch any water drips. You can also empty the tube by dispensing water from the system for about 60 seconds. 

Step 3: Replace the Filter

Insert the fresh LG filter into the cover and move it clockwise until it stops. For the optimal experience, I recommend keeping the cartridge knob in the upright position.

Steps to Changing the LG1000P Refrigerator Water Filter

Now take a wider picture of replacing LG brand filters. Let’s head over it.

Step 1: Find the Water Filter

The LG LT1000P water filter is typically located beside the refrigerator door. Find the release button or marked cover for the filter. If you need more clarification, consult your user manual for precise location details.

Step 2: Shut Off the Water Supply

Before changing the water filter, turn off the water supply to your LG LT1000P refrigerator. This prevents leaks and facilitates a smoother replacement process.

Step 3: Replace Water Filter

Locate the water filter at the bottom of the refrigerator door, you’ll find a release button or twist-lock mechanism. If your model uses a release button, simply press it to free the old filter. Alternatively, for a twist-lock system, rotate the old filter counterclockwise.

Once released, pull the old filter straight out from its compartment. Be mindful of the filter’s orientation to ensure the correct placement of the new one. Dispose of the old filter following local regulations, and you’re ready to install the fresh filter, ensuring continued access to clean and crisp water from your LG refrigerator.

Step 4: Install the New Filter

Insert the new filter, ensuring proper alignment. Lock the filter by turning it to the right until it clicks into place.

Step 5: Restore the Water Supply

Secure the new filter in place and reconnect the water supply. Run the dispenser for 2-3 minutes to flush air from the filter, allowing water to circulate and clearing any carbon dust from the installation.

Step 6: Check for Leaks

After flushing, check for any leaks around the filter. If there are no leaks, your new water filter is successfully installed and ready for use.

Step 7: Reset the Filter Indicator

If your refrigerator has a filter indicator light, reset it by following the specific instructions in your user manual. Typically, it involves holding the reset button for a few seconds.

Step 8: Indulge in pure, refreshing water

How Do You Handle a Stuck LG Filter?

Replacing the filter is a swift process unless you encounter a stuck one. But, don’t worry! I found an easy way to deal with the stuck filter.

Listed below are the easy steps you should follow:

1. Diagnose the Issue: Identify your filter type and understand its removal mechanism. Some filters require a simple twist, while others might involve additional steps. Such as pulling forward or bringing the filter down. 
2. Use a Filter Wrench or Pliers: For stubborn filters, a filter wrench or a pair of pliers can provide the extra grip needed for removal. Place the wrench or pliers around the filter cap and turn counterclockwise. Be cautious not to apply excessive force to avoid damaging the filter or the filter housing.
3. Twist in Both Directions: Experiment with slight clockwise and counterclockwise movements. This can help break any potential suction or adhesion between the filter and the housing. Be patient and persistent, as sometimes a gentle back-and-forth motion is more effective than a single forceful attempt.
4. Inspect for Obstructions: Check the filter and the housing for any visible obstructions or debris hindering the removal process. Clearing any blockages can make it easier to dislodge the filter.
5. Consult Customer Support: If your every effort fails, contact LG customer support. They can provide guidance based on your specific model, offer additional troubleshooting tips, or recommend professional assistance.

Shedding Light On The Value of Timely LG Filter Change

Regularly updating your LG refrigerator water filter holds paramount importance for various reasons. This recurring maintenance task is crucial to ensuring optimal appliance performance, preserving water purity, and safeguarding against the growth of harmful contaminants.

By adhering to the recommended replacement schedule, you not only enhance the lifespan of your LG refrigerator but also contribute to the cost-effective and efficient operation of the appliance. Here are some of it’s pros: 

1. Keeping Your Health Safe

Making your water look better and taste good is not the sole purpose of water filters. Instead, it is also necessary to safeguard your well-being. Drinking water tainted with dangerous compounds can have detrimental effects on one’s health, including respiratory and gastrointestinal disorders, as well as long-term health risks.

Therefore, you can lower your chance of getting exposed to these toxins and protect your health by changing your filter regularly.

2. Preserves Appliance Performance

A clogged or inefficient filter can strain your refrigerator’s water dispensing system, leading to decreased water flow and compromised performance. I found that replacing the filter is also recommended by the company itself which allows you to maintain optimal functionality, ensuring a consistent and efficient water supply.

3. Enhances Ice Quality

If your LG refrigerator dispenses ice, a clean and functioning filter is crucial for producing high-quality ice cubes. Regular replacements prevent impurities from affecting the taste and clarity of your ice, ensuring a refreshing experience every time.

Benefits of Using Refrigerator Water Filters

Now, I will shed light on the plus points of using refrigerator filters:

• Improved Water Quality: Refrigerator water filters improve the taste, smell, and appearance of water by removing impurities such as chlorine, rust, sediment, and other contaminants.
• Health Benefits: By removing impurities, refrigerator water filters help to reduce the risk of health problems such as gastrointestinal issues and other illnesses caused by contaminated water.
• Environmental Responsibility: Drinking water from the refrigerator dispenser lessens the amount of plastic waste produced by bottled water, making it a more environmentally friendly choice.
• Convenience: You don’t need to buy bottled water all the time when they have a refrigerator water filter because they can easily access clean, fresh-tasting water and ice in the comfort of their own homes.
• Cost-Effective: Refrigerator water filters are a cost-effective alternative to purchasing bottled water.

How Often Should I Change My Refrigerator Water Filter?

To ensure the best quality water and ice, replace your LG refrigerator’s water filter every 6-12 months, or as stated in your owner’s manual.

How Is the Quality of the Water Filters Determined?

Purification quality is measured in microns, the fewer microns there are, the better the filter will be at catching fine particles.

Most water filters for refrigerators use carbon, and the average size of them is 20 microns, primarily removing the impurities that affect taste and smell.

How Thoroughly Does the Filter in the Refrigerator Purify the Water?

Understanding how well refrigerator water filters purify water is crucial, as incorrect purification might pose health problems.

1. Does Not Remove Salmonella and Coliform Pathogens

Its biggest drawback is a refrigerator water filter’s inability to remove all pollutants. Salmonella and coliform pathogens slip through these filters, providing a major health concern. Even though the EPA purifies water before it enters the main line, many refrigerator water filters don’t filter out dangerous chemicals.

2. Is Great for Moisture-loving Bacteria

Your refrigerator’s water filter is great for moisture-loving bacteria. According to research, pharmaceuticals, bacteria, and parasites can remain in drinking water after purification. Refrigerator water filters only filter certain toxins found in the EPA’s purification system’s post-process, leaving bacteria and particulates in the water.

3. Needs Proper Maintenance for Hassle-Free Filteration

Maintaining water quality requires understanding refrigerator water filter limits. They help purify pollutants from the filtration process, and dispenser hygiene must be considered. Refrigerator water safety and purity depend on regular knowledge and maintenance.

FAQs

Conclusion

The final say is that Replacing LG fridge water filter is essential to contribute to your water cleanliness and make it more fresh than ever. For the beside-door models, you will have to take out the lower bin of your fridge. For the top interior models, you will have to locate the filter compartments at the top left shelf and then replace your fridge’s filter.

If your filter is stuck, I would recommend you inspect for obstructions and use a wrench or plier to loosen it. The timely filter swapping will not only improve your health but also increase the performance of your cooling machine.
