Water does not dispense - Refrigerator

Troubleshooting Refrigerators Last Updated 06/23/2017
Water Does Not Dispense

When water does not dispense, it may be related to operational issues that can be easily resolved. The recommended temperature for LG refrigerators is -4oF(20oC), if your unit's temperature is lower, this may cause frozen water lines which will prevent water from dispensing.

If you see any error code displaying on your refrigerator, please visit our Error Codes - Refrigerator article.

  1. 1

    Humming sound from dispenser.

    Press the dispenser button or lever. Listen to hear if the dispenser hums or sounds like its trying to dispense water.

    press the dispenser

    Do you hear the humming sound?

    Yes No
  2. 2

    New installations.

    For newly installed units, air may be trapped in the water line between the home water supply and the unit, which will prevent water from dispensing. Try holding down the dispenser lever until it dispenses water. Be sure to discard the first 1-2 gallons of water before consuming.

  3. 3

    Check water flow to dispenser.

    Check if water is getting to the dispenser. To do so, remove the filter and hold it over the sink with the tip facing down.

    check the filter

    Does water come out?

    Yes No
  4. Since there is water is in the filter, this indicates that the water supply is ON, but something is restricting the flow. With the water filter removed, try to dispense water. If the unit requires a bypass, it must be installed.

    If water dispenses from the unit, this indicates that either the filter needs to be replaced or the water pressure is too low.

    Water filter that should be changed every 6 months. If not replace regularly as directed, foreign particles may build up on the filter, which will reduce the water pressure and flow rate. If the filter was recently replaced, verify that it is installed correctly. To adjust the water pressure, please visit our Water Supply Section of this content.

    If water still doesn't dispense, the unit will require a repair service. Please visit our Request a Repair page.

  5. This indicates a possible water supply issue. Check the following:

    1Supply valve MUST be turned ON.

    Check all water supply valves to make sure they are opened completely.

    2Water lines MUST be connected.

    Check the connections behind the refrigerator to make sure all lines are connected. There are multiple connections points, so be sure to check carefully:

    1. Connection of the water line to the home water supply valve.

    2. Connection of the water line to the back of the refrigerator, at the main inlet valve.

    If the water lines are not connected correctly, this will cause the refrigerator to leak and will prevent water from dispensing.

    3Water lines MUST NOT be kinked.

    Sometimes when the unit is pushed back into its place, recently moved or installed, the water line gets kinked or pinched. Check to make sure that the water line is not pinched or kinked.

    4Check external filteration system (Reverse osmosis)

    An external filter reduces the water pressure going to the refrigerator, which may prevent water from dispensing properly. In this case, do not use the internal filter.

    If the refrigerator comes with a bypass, then it should be used instead.

    If water still dispenses slowly, the output pressure from the external filter may be too low. A water pressure regulator may be installed to increase that pressure.

  6. 2

    Check dispenser lock.

    When the lock icon Dispenser Lock Icon is illuminated, the dispenser and buttons will not operate when pressed. To unlock the dispenser, press and hold the LOCK button for 3-5 seconds to unlock the dispenser, then try dispensing water again.

    If the dispenser is unlocked but water is not dispensing, proceed to the next step.

  7. If the dispenser does not hum when you try to dispense water, the door switch may be disconnected. Test the door switch according to its type:

    APUSH SWITCH

    Push in the door switch to see if the lights turn off.

    Push Door Switch

    BREED (MAGNETIC) SWITCH

    Place a magnet over the switch to see if the lights turn off.

    Magnetic Reed Switch

    Do the lights turn off?

    Yes No
  8. If your unit have two doors, repeat the steps for the LEFT door, using the switch to test if the lights turn off. Otherwise, press YES to continue.

    Do the lights turn off?

    Yes No
  9. The door switch may be disconnected, even if the lights turn off, a slightly loose connection can cause dispenser issues. Let's take a look at the connection on the door hinge.

    After checking all connectors and pushing them in firmly, try to dispense again.

    Does the dispenser hum now?

    Yes No
  10. This indicates a possible water supply issue. Check the following:

    1Supply valve MUST be turned ON.

    Check all water supply valves to make sure they are opened completely.

    2Water lines MUST be connected.

    Check the connections behind the refrigerator to make sure all lines are connected. There are multiple connections points, so be sure to check carefully:

    1. Connection of the water line to the home water supply valve.

    2. Connection of the water line to the back of the refrigerator, at the main inlet valve.

    If the water lines are not connected correctly, this will cause the refrigerator to leak and will prevent water from dispensing.

    3Water lines MUST NOT be kinked.

    Sometimes when the unit is pushed back into its place, recently moved or installed, the water line gets kinked or pinched. Check to make sure that the water line is not pinched or kinked.

    An external filter reduces the water pressure going to the refrigerator, which may prevent water from dispensing properly. In this case, do not use the internal filter.

  11. Excellent, the issue is resolved. There may be air in the water line, so it may delay dispensing for a few minutes. Discard the first 1-2 gallons of water before consuming.
