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.

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 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.

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.

How Do You Handle a Stuck LG 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.

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:

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.

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.

Resetting your LG refrigerator after changing the water filter typically involves pressing and holding the reset button on the control panel. Consult your refrigerator’s user manual for specific instructions, as the process may vary based on the model.

Do refrigerator water filters really need to be replaced?

Yes, refrigerator water filters do require regular replacement. Over time, these filters can become clogged with contaminants, affecting water quality and appliance performance. It is advisable to follow the manufacturer’s recommendations and replace the water filter at specified intervals to ensure optimal filtration and maintain the integrity of your refrigerator’s water and ice maker.


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.
