How To Change Water Filter In LG Refrigerator

The water filter on a refrigerator removes contaminants from the water and ice it dispenses. Most refrigerator water filters simply remove chlorine as required by their NSF 42 certification, and aren’t strong enough to strain out the more dangerous contaminants.

How To Change Water Filter In LG Refrigerator

The CDCP (Center for Disease Control & Prevention) estimates that as many as 30 million Americans become sick as a result of ingesting contaminated water every single year.

LG refrigerator water filters are far more sophisticated, and can help to remove:

  • Pesticides
  • BPA
  • Asbestos
  • Pharmaceuticals
  • Atrazine
  • Chlorine
  • Lead
  • Mercury

Many of these chemicals were part of the process that were used to clean your water in the first place, and mainly just don’t taste good. Others, such as the metals, can be extremely harmful if they are allowed to build up in your body.

Removing certain contaminants from your water will have a big impact on the flavor of your water, and is obviously better for your health; giving you good, clean water that still has all the healthy minerals that should be there and contribute to nutrition.

Depending on the model of your LG refrigerator, the water filter is located in different parts of the appliance. The following instructions apply to the most popular LG refrigerators.

Step-By-Step Instructions For Replacing Your LG Refrigerator’s Water Filter

1. Remove The Top Shelf Of Your Refrigerator

The water filter is located above the top shelf of your refrigerator. In order to access the water filter, the top shelf must be removed.

  • Tilt the front of the shelf up, and lift it.
  • Remove it from the refrigerator

2. Remove The Old Water Filter

Locate the water filter housing and open it.

Pull the old filter downwards while turning it counter-clockwise. Once the filter has been rotated as far as it will go, remove it completely from the manifold hole.

You may now responsibly dispose of the old filter in line with the manufacturer’s instructions.

3. Install The New Filter

Remove the new filter from its packaging, including the protective covering on the o-rings.

Make that the filter tabs are facing horizontally, then push the new filter into the manifold hole.

Rotate the filter into place, then close the filter housing’s cover.

4. Flush Trapped Contaminants And Air

The filter has been replaced, but there are now trapped contaminants and air in the system.

Flush 2.5 gallons of water through the system in order to fully clear this. Press and release the dispenser at intervals of 30 seconds on, 60 seconds off, until the full amount of water has  been dispensed.

5. Reset The Water Filter Indicator

Your refrigerator display will show a ‘Replace Filter’ icon when the water filter needs to be changed. You must manually reset this once the filter has been replaced.

Press and hold the ‘Water Filter’ button for three seconds, and the icon will disappear.

Frequently Asked Questions

Frequently Asked Questions

Will My Unused Filters Expire?

No, they will not. Filters that you have in storage for the next time that your refrigerator’s water filter needs to be replaced will not expire- so long as they are kept dry.

This allows you to buy multiple filters at once in order to take advantage of sales and bulk pricing.

How Often Does My Water Filter Need To Be Replaced?

How often you need to replace your LG refrigerator water filters directly depends on how much you use the water dispensing features of your refrigerator.

This is usually never more than six months. Your refrigerator’s display will show a ‘Replace Filter’ button when it is time to be replaced.

Six months is the maximum amount of time that LG say there should be between replacing water filters. Any damages that result from having the water filter in for longer than this void your appliance’s warranty.

Can I Use Other Brands’ Filters In My LG Refrigerator?

LG actively condemns the use of third-party products with their appliances, and warns against the purchase of counterfeit water filters.

Water filters which are not LG products may not function to filter water in your refrigerator, and if they cause damage to your appliance then it shall no longer be covered under LG’s warranty.

To avoid difficulties, always purchase and use genuine LG water filters with your LG products.

What Happens If I Don’t Change My Whirlpool Water Filter?

Failure to change your water filter when the ‘Replace Filter’ indicator shows on your display, or before the maximum recommended usage of six months has elapsed may lead to problems with the functioning of your water filtration system.

  • Poor-tasting water
  • Slow-pouring water
  • No water dispensing (blockages)
  • Measured fill not correctly functioning
  • Misshapen or hollow ice cubes
  • Lower ice cube production
  • Cloudy or sediment-containing water

The biggest concern of your water filter not functioning in your refrigerator is that the harmful contaminants that you are attempting to remove from the water that you consume.

And which you have paid for in purchasing your LG appliance, will once again have re-entered your water supply. The water that you and your family consume will once again be tainted.

Failure to heed LG’s advice in maintaining your refrigerators water filtration system will void your warranty with LG, and means that if any damage is caused to your refrigerator through your failure to regularly replace your water filter means that you will be paying out of you own pocket for repairs.

Non-functioning water filter can lead to a buildup of scale in the water lines of your refrigerator, particularly if you live in an area with hard water.

Minerals from your water source will gradually accumulate within your system leading to blockages, and potentially damage. This can cause low pressure in your system and even lead to your refrigerator breaking entirely.
