Water dispenser quit working after a few hours after replacing filter. Have water pressure up to filter but nothing making it to the dispenser. Could it be that the new filter had something in it and plugged the line to the dispenser and if so can I blow some air thru the line from the dispenser back to where the filter goes to remove the blockage.

The error code dH on your LG refrigerator is indicating a water supply problem. This could be caused by a few different issues:

1. Clogged or frozen water line: The water line supplying the icemaker and water dispenser may be clogged or frozen. This can prevent water from flowing to the icemaker and dispenser. Check the water line and make sure that it is not clogged or frozen.
2. Water inlet valve: The water inlet valve that supplies water to the ice maker and dispenser may be faulty or clogged. This can prevent water from flowing to the icemaker and dispenser. You can check the water inlet valve and make sure it is functioning properly or if it is clogged.
3. Water filter: A clogged water filter can prevent water from flowing to the icemaker and dispenser. If your refrigerator has a water filter, make sure that it is not clogged and has been replaced recently.
4. Water pressure: If the water pressure is too low, it can prevent water from flowing to the icemaker and dispenser. Make sure that the water pressure in your refrigerator is adequate.

You should first try to check the water line, water inlet valve, water filter, and water pressure. If none of these solutions work, please contact a professional technician or LG customer service to diagnose and fix the problem.

repairs should be performed by a qualified repair person. when replacing a filter make sure the filter properly installed. once secured get 3,1 gallon containers to purge the water line and reservoir. BEWARE! water may continue to run while flushing the water line. this is why you'll need 3 containers. once you are able to finish flushing the line and the water is no longer gray the flushing for the water dispenser is complete. dispose the ice in the container in the freezer. let the ice maker cycle a few hours then dispose the filtered ice. once copleted you're done.

Have you changed the water filter? they can plug up over time. The water tube can freeze in the door. To test this there usually is a disconnect under the freezer door side of the grill you can disconnect this and hit the water dispenser lever. If the door is getting water then it is frozen in the door. If not the water valve could be your problem there are two sides to the water valve one for the water dispenser and one for the icemaker. A last possibility is there is a water tank or tubing loop in the refrigerator behind the crisper this could have frozen.

Problems with Ice Maker/Water Dispenser
If you are not getting ice, make sure the water valve is open and the ice shutoff switch or arm is not in the "Off"
position. Inspect the ice ejector arm for blockage and remove any trapped ice with a plastic spoon. If you recently
emptied the ice container, remember that it takes your refrigerator up to 24 hours to produce ice.
Low water pressure is the major cause of problems with the water/ice door dispenser. Low water pressure can cause
inadequate water flow and small or hollow ice cubes. Check the water line for kinks that may interfere with water
flow and make sure the water valve is open. A dirty water filter can color the water and ice cubes, impede water
flow or cause water to have an off taste so remove, clean and replace it.
If water is leaking from the door dispenser, make sure the water glass remains under the spout until the water
shuts off completely. If you recently changed the water filter, air that was left in the line may cause water to
spurt from the dispenser. To flush the water line, let water run from the dispenser for approximately three minutes
or until you draw out 1.5 gallons of water. Try to find a container that will fit under the dispenser spout so you
do not have to start and stop to empty the container.

Have a nice day my friend : )

Hi,

Check the water line for kinks and straighten if there are any.
Remove the water filter and see if you get more water and it makes ice. If it works properly, then the filter either needs replacing or was not in correctly.
Do you have good cold water pressure in the rest of the house? Low water pressure will result in these problems also.

Good luck.

Hope this helps. If it does, I'd appreciate your vote. Thanks,

Two things come to mind.

First, the water valve at the bottom rear of the refrigerator may have failed. You didn't mention if there is a water dispenser and whether or not this is still working. This valve pumps water to the icemaker and water dispenser when the control unit of the icemaker calls for water. Also, there could be a blockage in the line which brings the water to the icemaker.

The other possibility is that the part of the icemaker controls which calls for water from the valve has failed. If this has happened, it would likely be more cost effective to replace the icemaker unit.

change your water filter its probably full of dirt and plugged

You need to replace the dual solenoid one side is for the water the other is for the ice.

may i know the exat model no

sounds like the water tank in back of refrig is freezing up ,,,,, turn temp down and allow 24 hours for it to make adjustments
