You will need to shut off the water supply and unplug the refrigerator before accessing internal components. You can access the water valve assembly by removing the bottom rear service panel on the outside back wall of the refrigerator. You should be able to find the water tube that goes from that valve assembly to the filter. You can disconnect that tube from the water valve. It may have a John Guest water fitting on the valve assembly. To disconnect the water line from that type of fitting, just push in on the collar of the fitting and pull the water tube out. The water filter housing should have the same type of fittings. If you find a compression fitting on the valve assembly, you will need to unscrew the compression fitting to remove the tube. You can remove the front grill of the refrigerator and then remove the screws that secure the filter housing to the base of the refrigerator cabinet. You should have enough slack in the outlet water tube to pull the housing out from the front of the refrigerator and remove the inlet water line. Replace the line and reassemble the refrigerator. The water line will just push into the John Guest water fitting. Push it all of the way in and then tug on it to make sure that it is properly seated. Check for leaks. This information should help you complete this repair. If you need more assistance, reply with additional details and we will assist you further.
