How to Change the Water Filter in Your LG Refrigerator: A Pro’s Guide

Changing your LG refrigerator’s water filter is a crucial maintenance task that ensures you and your family are drinking clean, fresh water. Doing it yourself is surprisingly easy and can save you time and money compared to calling a technician.

Step-by-Step Instructions: Fresh Water Awaits

Here’s a comprehensive guide on how to change your LG refrigerator water filter, covering the most common models:

1. Identify Your Filter Location: LG refrigerators typically have the water filter located in one of three places:

   • Upper Right Corner (Inside the Refrigerator): This is the most common location for newer models. Look for a rectangular or cylindrical housing.
   • Lower Grille (Outside the Refrigerator): Some older models have the filter located behind the base grille at the bottom of the refrigerator.
   • Upper Left Corner (Inside the Refrigerator): Less common, but check if you don’t find it on the right.

2. Prepare for the Change: Before you begin, have these items ready:

   • A new LG water filter (make sure it’s the correct replacement – check your model number!)
   • A clean towel or rag to wipe up any spills.
   • A small container (optional) to catch any drips.

3. Turn Off the Water Supply (Recommended): Although not always strictly necessary for some models, turning off the water supply valve to your refrigerator provides an extra layer of protection against leaks. The valve is usually located behind the refrigerator or under the sink.

4. Remove the Old Filter: The removal process varies slightly depending on the filter location:

   • Upper Right/Left Corner Filters (Push and Turn):
     • Locate the water filter housing.
     • Gently push in on the end of the filter housing. You should feel a slight click.
     • Turn the filter counterclockwise (usually about 90 degrees).
     • Carefully pull the filter straight out. Be prepared for some water to spill.
   • Lower Grille Filters (Twist and Pull):
     • Locate the filter housing behind the grille.
     • Twist the filter counterclockwise to release it.
     • Pull the filter straight out.

5. Prepare the New Filter:

   • Remove the new filter from its packaging.
   • Remove the protective cap(s) from the end of the filter.
   • Lubricate the O-rings (rubber seals) on the new filter with water. This helps ensure a proper seal and makes installation easier.

6. Install the New Filter:

   • Upper Right/Left Corner Filters (Push and Turn):
     • Align the arrows on the new filter with the arrows on the filter housing.
     • Push the filter straight into the housing until it’s fully seated.
     • Turn the filter clockwise until it locks into place with a click.
   • Lower Grille Filters (Twist and Push):
     • Align the filter with the housing.
     • Push the filter in until it’s fully seated.
     • Twist the filter clockwise to lock it into place.

7. Turn the Water Supply Back On (If Turned Off): Slowly turn the water supply valve back on.

8. Flush the New Filter: This is a critical step. You need to flush the new filter to remove any air or carbon particles.

   • Dispense water from the refrigerator’s water dispenser for approximately 5 minutes (or about 2.5 gallons).
   • Dispense the water in short bursts (30 seconds on, 30 seconds off) to prevent the system from overheating. The water may appear cloudy or discolored at first, but it should clear up as you flush.

9. Reset the Water Filter Indicator: Most LG refrigerators have a water filter indicator light that needs to be reset after you change the filter. The reset procedure varies depending on the model:

   • Common Method: Press and hold the “Water Filter” button (or sometimes “Ice Plus” or “Light”) for 3-5 seconds until the indicator light turns off or changes color.
   • Check Your Owner’s Manual: If you’re unsure, consult your owner’s manual for the specific reset procedure for your model.

10. Check for Leaks: Carefully inspect the filter housing and the water supply connections for any leaks. Tighten connections if necessary.

Frequently Asked Questions (FAQs)

1. How often should I change my LG refrigerator water filter?

LG recommends changing your water filter every 6 months, or more frequently if you notice a decrease in water flow or a change in water taste or odor. Failing to replace the filter regularly can lead to decreased water quality and potentially damage your refrigerator.

2. How do I find the correct replacement water filter for my LG refrigerator?

The easiest way to find the correct replacement filter is to check your refrigerator’s owner’s manual or look for the model number printed on the old filter itself. You can also use the refrigerator’s model number to search online for compatible filters at appliance parts retailers. Always verify compatibility before purchasing.

3. What happens if I don’t change my water filter?

If you don’t change your water filter regularly, it can become clogged with sediment and contaminants, reducing water flow and water quality. This can also put a strain on your refrigerator’s water system and potentially lead to costly repairs. Furthermore, an old filter can become a breeding ground for bacteria and mold.

4. Can I use a generic water filter in my LG refrigerator?

While generic filters may be cheaper, it’s generally recommended to use genuine LG water filters. Genuine filters are designed specifically for your refrigerator model and are more likely to provide optimal performance and protect your refrigerator’s water system. Generic filters may not fit properly or meet the same quality standards, potentially leading to leaks or reduced filtration effectiveness.

5. How do I reset the water filter indicator light on my LG refrigerator?

The reset procedure varies depending on the model. Typically, you need to press and hold the “Water Filter” button (or sometimes “Ice Plus” or “Light”) for 3-5 seconds until the indicator light turns off or changes color. Consult your owner’s manual for the specific instructions for your model.

6. What if I can’t remove the old water filter?

If you’re having trouble removing the old filter, make sure you’ve turned it to the correct position (usually counterclockwise). You can also try using a rubber jar opener or wearing rubber gloves to get a better grip. If it’s still stuck, you may need to call a qualified appliance repair technician.

7. What does it mean if my water filter indicator light is blinking?

A blinking water filter indicator light usually means that it’s time to replace the filter. However, it can also indicate a problem with the water system or the filter itself. If the light continues to blink after you’ve replaced the filter and reset the indicator, consult your owner’s manual or contact LG customer support.

8. Why is the water from my refrigerator cloudy after changing the filter?

Cloudy water after changing the filter is usually caused by air bubbles trapped in the system or carbon particles being released from the new filter. This is normal and should clear up after you flush the filter for the recommended amount of time (about 5 minutes or 2.5 gallons).

9. What do I do if my refrigerator is leaking after changing the water filter?

If your refrigerator is leaking after changing the water filter, first check to make sure the filter is properly installed and locked into place. Also, inspect the O-rings on the filter for any damage. If the leak persists, turn off the water supply to the refrigerator and contact a qualified appliance repair technician.

10. Can I clean my water filter instead of replacing it?

No, water filters are designed to be disposable and cannot be effectively cleaned. Attempting to clean a water filter can damage it and compromise its filtration effectiveness.

11. Why does the water taste different after changing the filter?

A slight difference in water taste after changing the filter is normal and is often due to the new activated carbon in the filter. The taste should improve after you flush the filter for the recommended amount of time. If the taste is unpleasant or persists for more than a few days, contact LG customer support.

12. Where can I buy LG water filters?

You can buy LG water filters from appliance parts retailers, online retailers like Amazon, and directly from the LG website. Make sure to purchase from a reputable source to ensure you’re getting a genuine LG filter.
