GENERAL INFORMATION Section 1: General Information This section provides general safety, parts, and information for the “Whirlpool® and KitchenAid® Filtration and Maytag® 24" Microfiltration Dishwashers.
GENERAL INFORMATION (Cont.) Dishwasher Safety Your safety and the safety of others are very important. We have provided many important safety messages in this manual and on your appliance. Always read and obey all safety messages. This is the safety alert symbol. This symbol alerts you to potential hazards that can kill or hurt you and others. All safety messages will follow the safety alert symbol and either the word “DANGER” or “WARNING.
GENERAL INFORMATION (Cont.) General Theory of Operation Maytag® Microfiltration Wash System No Filter Cup, No Chopper The industry’s first microfiltration system is a clear departure from traditional, passive filtration because it continuously filters 100% of the water, reducing the cycle time and energy consumption on the heaviest loads. Similar on the Surface, Radically Different Inside The only visible filtration component of the new filtration system is the coarse filter in the bottom of the tub.
GENERAL INFORMATION (Cont.) Whirlpool® and KitchenAid® Global Wash Filtration System This dishwasher has an updated technology in dishwasher filtration. The triple filtration system minimizes sound and optimizes water and energy conservation while providing superb performance. Throughout the life of the dishwasher, the filter will require maintenance to sustain peak cleaning performance. The triple filter system consist of a fine-filter plate and a dual filter cup assembly.
GENERAL INFORMATION (Cont.) 2. Insert the Dual-Filter Assembly into the circular opening in the fine-filter plate. 3. Slowly rotate the filter clockwise until it drops into place. Continue to rotate until the filter is locked into place. If the filter is not fully seated (still turns freely), continue to run the filter clockwise until it drops and locks into place. NOTE: The Dual-Filter Assembly arrow does not have to align with the arrow in the fine-filter plate as long as the filter is locked.
