Fridge filters can take out some impurities like dirt, chlorine taste and smell, and even some metals like lead. But they can’t get everything. For example, they won’t remove things like total dissolved solids, arsenic, medicine, and fluoride. Different fridge filters also work differently. Some say they can remove up to 99% of certain things, but that depends on the filter.

To keep your ice maker happy, you need to take care of it regularly and change the filter when LG says to. Also, take a peek at the parts in your fridge now and then to make sure everything looks good.

LG fridge users give a great tip for installing a new water filter. They say to put the filter tabs flat like a straight line, then push it firmly into the round hole in the machine. After that, just turn it right as far as it goes. It’s a simple step, but important to make sure filter fits right.

if you are ever in doubt or run into trouble, professional assistance is always an option. Regular maintenance of LG ice maker, including routine filter replacement, checking for leaks, and ensuring efficient refrigerator operation, can prevent issues like knocking noises.

After ensuring that your LG refrigerator water filter is properly installed, it is crucial to check the water line connections and water pressure. Inspect the water line connections

Make sure the water supply is properly connected to a cold water supply and that the shutoff valve is fully open. This is a simple but vital step to guarantee that your fridge receives the water it needs.

If you find any kinks in the water supply line, straighten them out to restore adequate water flow and pressure. a kinked line can significantly reduce water flow, so it’s worth taking the time to check.

Adjusting water pressure is another key aspect. If you notice unusual noises coming from your fridge, you can partially close water valve connected to the refrigerator to decrease water pressure. This might help reduce noise and prevent potential leaks.

If you’re unsure about the water pressure, here’s a quick guide:

  • Low water pressure (<20 psi): Can lead to insufficient ice production or water dispensing issues.
  • Ideal water pressure (20-120 psi): Ensures optimal performance of the ice maker and water dispenser.


Resetting that annoying water filter light on your LG fridge is a breeze. Simply press and hold the “Reset” button for 3 seconds, and voila – light’s out!
