CZS22MSKGHSS General Electric - Overview

The Top Filter Housing on this refrigerator contains some sort of Excess Flow Check Valve to prevent water flow if there is no filter installed. When the spring on this valve weakens over time, the valve closes unnecessarily with normal flow and chatters. This sounds like a woodpecker hammering on the side of your house and water flow is almost non-existant. You may have heard the same thing after you changed the filter if there was air in the system. The noise stops and you have normal water flow once the air is vented out of the filter. If you start hearing this noise unprovoked (filter has not been recently changed), the Top Filter Housing needs to be replaced. To replace this part, you will need a 1/4" and 5/16" nut drivers or sockets and two 1/2" open ended wrenches. You might also need plumber's putty. Shut off the water and have a bucket ready to drain the water into. Remove the lower cover from the back of the refrigerator. Disconnect the two hoses going to/from the top filter housing. One is connected to the main water line, the other is connected to the Water Fill Valve located in back of the refrigerator on the bottom left corner. Un-screw the cover plate from the back of the refrigerator and pull the plumbers putty out (can be re-used if still pliable). On the inside of the refrigerator, pull the plastic cap off the Top Filter Housing to expose the two screws holding it in place. Remove the two screws and pull out the Top Filter Housing with Tubing. Replacement is the reverse of what you just did. If the tubing is a little short, you will want to unbolt the Water Fill Valve from the refrigerator prior to re-connecting it to ensure a water tight connection.

Moved refrigerator out from wall. On the back of the refrigerator at the bottom there is a metal plate. Removed this plate with a socket wrench to expose where the end of the tube pluged in. The grommet securing the tube, white on my unit, had to be pushed up to release the old tube. I pushed the new tube into where the old one was and it self secured the tube. The other end of the grommet I pushed through the hole feeding the ice maker,first pushing out the broked part with a screwdriver,and securing that end with the attached sticky tape already attached to the grommet. I cleaned the area around the hole with alcohol before attaching the grommet.Replaced metal plate and done. No leaks.

After thawing out freezer pushed water supply tube out from inside freezer diconneted the supply line from the valve assembly by pushing in the bushing with my finger and inserting the new line. Sadly that wasn't the problem!For anyone with the same symptoms of ice building up on your ice maker, to the point where it clogged the water supply line and started leaking from the grommet assembly. The problem is the valve not closing when the ice maker does not need any water. so I ordered a new valve and hopefully that will fix my problem.
