Add Rinse Aid Add Rinse Aid Fill the Rinse Aid dispenser when the Add Rinse Aid indicator is lit. A rinse aid prevents water from forming droplets that can dry as spots or streaks. Rinse Aid is essential for efficient drying.
TM WASH SYSTEM The three-level wash system provides excellent cleaning results. Three levels of filtration filter the wash water, and prevent food particles from redepositing on the clean dishes. The three levels operate as follows: • A coarse strainer as part of the Drain Stopper assembly (1), prevents bones, pits, and other large objects from entering the pump system. • Items small enough to pass through the coarse stainer are caught in the Drain Screen Basket (2).
Hot Water Tank Operation To reduce the risk of scald injury, the Temp Control switch has been factory set to “LOW” (bottom position) which heats water to 120°F / 49°C. If faster dishwasher cycle time is desired, the Temp Control switch can be set to “HIGH” (top position) which heats water to 165°F / 74°C. The FREEZE PROTECT (center) setting will restart the tank periodically to prevent freezing. Use this setting if the hot water tank and dishwasher will not be used for an extended period of time.
