If your LG refrigerator is dispensing water slowly, not dispensing water or have any difficulties producing ice, it may be due to low water pressure or slow water flow.

  • To check the water pressure in your home, check the ice dispenser first and see if it is producing the correct amount of ice per tray, a half filled ice tray may indicate low water pressure as well as hollow or soft shell ice.
  • You can also use at any 7 ounce cup and place it under the water spout.
  • Using a stop watch, synchronize the time it takes to fill up the cup. 3 and 1/2 to 8 seconds is Normal Range for water pressure.
  • Anything over 8 seconds may indicate possible low water pressure.

Here are a few troubleshooting steps.

  • LG recommends that you change your water filter once every 3 to 6 months depending on the quality of your city's water, household consumption, refrigerator gallon capacity.
  • This may need to be done more frequently to prevent foreign particles from clogging your water filter.
  • Not changing the water filter as recommended may cause water flow to become slow.
  • If your unit is equipped with water filter, it also comes with a bypass cartridge or plug.
  • Refer to your owner's manual first.
  • You have the option of using the bypass cartridge in place of the water filter.
  • Once installed, run another time test to check for a noticeable speed flow difference.
  • This may take a few attempts to allow for air to be removed from the lines as you dispense water.
  • If the water pressure has increased, it's an indicator that a new water filter is needed which you can purchase online or at your local home improvement store.
  • Make sure that there are no kinks or bends in the water lines connected to the back of the refrigerator.
  • Check to make sure that the valves for the water lines connected to your refrigerator (and the main water lines to your home) are fully open.
  • In some instances, home may have self-piercing saddle valve kits, clamped on the waterline.
  • Just close a saddle valve and reopen it to help clear any clogging.
  • Run another water dispenser time test.
  • If the steps mentioned don't help improve the problem, a plumber may be needed.
  • The following may cause a decrease in water flow: Home water filtration system, or a reverse osmosis system may affect the flow of your water.
  • Depending on the filtration system, there may be a reduction in overall water flow.
  • Check your filtration systems owner's manual for more details.
