First of all we want to calm you down as you are seeing water on the floor near your Sub-Zero refrigerator, water dripping from the door, or water inside the refrigerator compartment, the culprit may not be a leak in the plumbing connection or water lines. Oftentimes, the cause of water buildup is simply a clogged drain tube. Surely, that is an unpleasant discovery and indicates improper maintenance. Don’t panic, this issue can be eliminated easily. Every time you open the refrigerator door, warm air carrying water vapor rushes into the compartment. As that warm air cools down, it and the water vapor it carries loses energy, and when water vapor loses energy, it turns from a gas back into a liquid. This is condensation and it happens in every refrigerator to some degree. Your Sub-Zero refrigerator is designed with a drain trough and drain tube in the bottom of the refrigerator, and a drain pan below, to remove this condensation. Sometimes, food debris may clog the drain tube or the water in it may freeze. In either case, this prevents the Sub-Zero from draining, water begins to pool under the crisper drawers, and if enough water accumulates, it can pool against the door and drip when it is opened. If there is ice on the floor of the refrigerator section, the drain tube is likely frozen. Use a hair dryer on low to defrost the unit. To remove food debris or other obstructions, use a pressurized air source, such as a compressed air duster, to blow out the drain. Do not put anything down the tube, such as the tip of the air can or a brush, as it may pierce the tube and void your warranty. If the door opens too easily, the door gasket may be worn and unable to maintain a vacuum seal, letting in warm air even when the door is closed. If this is the case, you will need a Sub-Zero door gasket replacement. Clean your condenser regularly. If it has not been cleaned in the past 6-12 months, schedule a condenser clean today. Take care of your refrigerator and it will be a loyal and faithful servant.
