Before we dive into the reasons behind the plastic-like taste in your LG fridge water, let’s start by understanding the key components of LG refrigerators that play a role in water quality.

LG Fridge Components

Water ReservoirStores a supply of water for the refrigerator’s dispenser and ice maker.
Water LinesTransport water from the source to the dispenser and ice maker.
Water FilterPurifies water by removing impurities and odors.
Dispenser and NozzleResponsible for delivering water to your glass.
Plastic PartsVarious components, including water reservoirs and tubing, can be plastic.

Now that we have a basic understanding of these components, let’s explore why they might contribute to the plastic taste in your fridge water.

Common Causes of Bad-Tasting Water in LG Fridges

There are several common culprits when it comes to that unpleasant plastic-like taste in your LG fridge water. Let’s take a closer look at each of them:

1. New Fridge Smell and Taste

When you first start using a new LG refrigerator, it may have a distinct “new” smell and taste. This can include plastic or chemical-like flavors. These odors and tastes can leach into the water supply system and affect water quality.


  • Flush the Water System: Dispense and discard several gallons of water to flush out any residual odors or flavors.
  • Clean the Interior: Use a mixture of mild soap and water to clean the fridge’s interior, including the water reservoir and water lines.
  • Replace the Water Filter: Follow the manufacturer’s recommendation for replacing the water filter to improve water quality.

2. Plastic Water Lines

Many LG refrigerators come equipped with plastic water lines that connect to the water supply. Over time, these plastic lines can absorb odors and flavors, leading to a plastic-like taste in the water.


Consider replacing the plastic water lines with copper or stainless steel lines, which are less likely to absorb odors and flavors.

3. Contaminated Water Supply

Sometimes, the problem may not originate from your fridge but from the water supply itself. The taste and quality of the water your refrigerator dispenses may suffer if your tap water has impurities or contaminants in it.


Install a water filtration system at the source of your tap water to remove contaminants such as chlorine, sediment, and bad odors, resulting in cleaner and better-tasting water.

4. Dirty Water Reservoir or Dispenser

The water reservoir and dispenser in your LG fridge can accumulate dirt, bacteria, and mineral deposits over time. This buildup can lead to an unpleasant taste in the water.


Regularly clean and sanitize the water reservoir and dispenser. Use a mixture of vinegar and water to remove mineral deposits and disinfect the components. Rinse thoroughly afterward.

5. Old or Expired Water Filter

If your LG refrigerator is equipped with a water filter, it’s essential to replace it regularly. Over time, these filters can become clogged and less effective at removing impurities, resulting in a plastic-like taste in the water.


Refer to your refrigerator’s user manual to determine the recommended replacement schedule for the water filter. Typically, it’s advisable to replace the filter every six months or as specified by the manufacturer.

Take a moment to describe the taste and odor of the water. Does it truly resemble plastic, or is there another undertone that might offer clues to the issue? Identifying specific characteristics can help narrow down the problem.

2. Water Source Analysis

Consider the source of the water supplied to your refrigerator. Is it tap water from a municipal source, well water, or another water supply? Different sources may have varying levels of impurities.

3. Check the Water Filter

Inspect the status of your refrigerator’s water filter. Is it old and overdue for replacement, or is it relatively new? An expired filter can lead to poor water quality.
