Jen Air Refrigerator (JCD2290HEW) developed problem with having low water flow at water dispenser and water hammer after changing water filter and depressing water dispenser to remove air. Have changed the filter three times with the filter recommended by the manufacturer and have replaced the dual flow valve in back of refrigerator without success. When I remove the filter and install the bypass filter cover, water flow comes out with a good deal of pressure and no water hammer. Going back and re-instaling the water filter causes the problem to resurface.

Water dispenser doesn't work

1. Dispenser control board

If the water dispenser is not functioning at all the most likely cause is going to be the dispenser control board. The dispenser control board governs the major portion of the systematic functions of the dispenser and is less likely to be the issue if only certain components are malfunctioning. If the dispenser control board is at fault, it will need to be replaced.

1. Water inlet valve & low water pressure from house supply

If the water dispenser on your refrigerator is not working properly, one of the first things to consider as an issue is the water pressure to your appliance. The water dispenser cannot properly function with a psi less than 20. If psi is appropriate, proceed to replace the water inlet valve to correct the issue. You may also be dealing with low household water pressure. This low flow can be examined by using a water pressure test gauge. Once the household water pressure is resolved, you can double check your refrigerator connection to ensure it is now flowing properly and that the water dispenser is functioning.

1. Water tube in door is frozen

If the water dispenser is not working on your refrigerator, the issue could be a frozen water supply tube located in the door. Although this may be a tricky problem to locate, the first thing to do is find a connection point in the tube. After this has been found, attempt to blow air through the tube. If the air flows freely through the tube, it is not frozen and this is not the issue. If it does not, the tube is frozen and needs to be removed to thaw out. As it thaws, attempt to ascertain why it froze and correct the positioning of the tubing to prevent the issue from occurring again in the future.

1. Dispenser switch

If the refrigerator water dispenser is not working properly you could be dealing with a defective dispenser switch. Activated by the dispenser actuator, the switches are responsible for numerous actions including ice cube disbursement, type of ice, and water controls. The switch can be tested using an ohm meter and should be replaced if it does not reveal continuity.

1. Water filter

If your water dispenser's flow is running slow check to ensure that your water filter is not clogged. If after checking you determine that the filter is clogged, simply replace the filter. Filters should be replaced every six months to ensure clean drinking water.

1. Door switch

If the refrigerator water dispenser is not working, the functionality of the door switch can be inspected. This switch is responsible for turning on the light in the freezer and simultaneously turning off the water dispenser when the freezer door is opened. If this switch malfunctions, it will show no continuity on the ohm meter and will require replacement.

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 : )

The vibration is a tiny bit of "water hammer." Previous to your filter change, the water flow was restricted, and therefore incapable of causing water hammer. Now that you've changed the filter, the flow is large enough to cause a little water hammer when you shut off the flow.
How to fix: shut off the flow SLOWLY. Water hammer is caused when the flow of water is shut down quickly. This is just as true with large flows (as in fire engine pump panels), as it is in itsy bitsy
filtered water lines & filter housings.

Any time that you replace the water filter you need to run about 2 gallons through the dispenser. The new filter is full of air not water, you just need to flush the air out of the system. The trickle is water siphoning through because the air is still in the system.

I believe your new Jen-Air has an old model number placed above your post. If you had a newer model nuber I could see if changes were made to the solution. The ods are no changes. I it possible you may have missed removal of te flilter plug? It also is your first time and to press the 2 buttons at same time for 8 to 10 seconds may be a little confusing. I bet after this time you will have this down to an art! here is what I could find without the vorrect model number if that is what happened or not.Jenn-Air
Press and hold the light and lock buttons until the change filter light flashes.
It is very easy to reset your filter indicator light on your Maytag refrigerator. Simply press and hold the light and lock buttons, on the dispenser, for about three (3) seconds, until the change filter light blinks.

this is a pressure problem . some times caused by line size . but generaly changing the water valve will correct this problem . ****

If there is a filter on the unit, change it. If not, then sounds like the screen is clogging up. You will need to pull the unit out and remove the water supply line and take off the adaptor to access the filter screen and clean it...

hi, this can be because of the filter. when the water is flowing threw the filter, it is sent threw many channels inside the filter before it reaches the dispenser. this slows it down a bit. this is quite normal but, if it's slowed down to a dribble, i suspect a water valve malfunction or you may need to change the filter.

You may have air in the system. When you actuate the dispenser it opens an electric valve in back to start the flow of water. When you release the dispenser air in the system expanding will cause the water to continue to flow until the pressure equalizes.
