Customer Questions and Answers for Water Valve by Whirlpool

Hello Elizabeth, The owners manual has only this to say about the filter: Interior Water Filter Installation (on some models) The interior water filter cartridge is located in the upper righthand corner of the fresh food compartment of the refrigerator.The interior water filter cartridge should be replaced every six months or earlier if the flow of water to your water dispenser or ice maker decreases noticeably. (See “Replacing an interior water filter cartridge” in the features section of this book.) Installing the interior water filter cartridge NOTE: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. 1. Carefully remove the interior water filter cartridge from its packaging. Remove the red cap from the cartridge. 2. Apply the appropriate month sticker to the cartridge as a reminder to replace the cartridge within six months. Then apply the “Water Filter Replacement Reminder” sticker to your calendar as a reminder to replace the cartridge in six months. 3. Line up the INSTALL mark on the water filter label with the indicator line that is molded into the filter mounting bracket cover. Push the cartridge into the filter mounting bracket. Twist the cartridge Z\v turn to the right to lock it into place. The REMOVE mark should be lined-up with the indicator line located on the front cover. 4. RUN WATER THROUGH THE DISPENSER UNTIL THE WATER RUNS CLEAR (about 2-3 gallons or 6-7 minutes). This will clean the system and clear air from the lines. Additional flushing may be required in some households. NOTE: As air is cleared from the system, water may spurt out of the dispenser. 5. Open the refrigerator door and inspect the filter system for water leaks. If you see water leaks, see the “Troubleshooting” section. NOTE: You can run the dispenser without a water filter cartridge. Your water will not be filtered. Notice the manual says right under the first line "on some models". If the filter isn't found where it says it is, there is none. The issue you are having though, can be caused by the electrical contacts in the ice maker motor module. Check also to make sure the fill tube isn't frozen up. If it is, it can be thawed out with a hair dryer. If the fill tube is frozen up you should also check the water supply line for crimps. If it is connected to the water supply with a self-tapping saddle valve, the manufacturers all recommend to drill the pierced hole out to a full 1/4 inch hole.
