DISHWASHER CARE Cleaning Cleaning the exterior In most cases, regular use of a soft, damp cloth or sponge and a mild detergent is all that is necessary to keep the outside of your dishwasher looking nice and clean. If your dishwasher has a stainless steel exterior, a stainless steel cleaner is recommended. Drain Air Gap Check the drain air gap anytime your dishwasher isn't draining well. Some state or local plumbing codes require the addition of a drain air gap between a built-in dishwasher and the home drain system. If a drain is clogged, the drain air gap protects your dishwasher from water backing up into it. Cleaning the interior Hard water minerals can cause a white film to build up on the inside surfaces, especially just beneath the door area. Do not clean the dishwasher interior until it has cooled. Wear rubber gloves. Do not use any type of cleanser other than dishwasher detergent because it may cause foaming or sudsing. To clean interior Make a paste with powdered dishwasher detergent on a damp sponge and clean. OR Use liquid automatic dishwasher detergent and clean with a damp sponge. OR See the vinegar rinse procedure in "Spotting and filming on dishes" in "Troubleshooting." NOTE: Run a normal cycle with detergent after cleaning the interior. The drain air gap is usually located on top of the sink or countertop near the dishwasher. To order a drain air gap contact your local dealer, or in the U.S.A., call the Customer Interaction Center and ask for Part Number 300096. NOTE: The drain air gap is an external plumbing device that is not part of your dishwasher. The warranty provided with your dishwasher does not cover service costs directly associated with the cleaning or repair of the external drain air gap. To clean the drain air gap Clean the drain air gap periodically to ensure proper drainage of your dishwasher. Follow the cleaning instructions provided by the manufacturer. With most types, you lift off the chrome cover. Unscrew the plastic cap. Then check for any soil buildup. Clean if necessary. Storing Storing for the summer Protect your dishwasher during the summer months by turning off the water supply and power supply to the dishwasher. Winterizing your dishwasher Protect your dishwasher and home against water damage due to freezing water lines. If your dishwasher is left in a seasonal dwelling or could be exposed to near freezing temperatures, have your dishwasher winterized by authorized service personnel. 20
