Page 9: Operation And Cycle Information
Operation and Cycle Information This section of the guide provides details on segments of cycles, timing of cycles, temperature expectations, and cycling of the heater during the dry portion of a cycle. Auto Hot Start At the beginning of the main wash, the dishwasher checks the temperature of the water, and if it is below 90°F, then it will add up to 10 minutes of time to heat the water to 90°F by circulating the water while the heater is on. - Page 10 Cycle Times (Estimated) NOTES: Cycle times will vary depending on options selected, incoming water temperature, and soil level (some models). • Incoming water temperature of 120°F to 140°F is recommended. • Circulation has built-in pauses (see Two Port Diverter in the Circulation System section of this guide).

Page 25: Circulation System
Circulation System With only 0.75 to 0.95 gallons of water, filtration is the start of improved performance. Water is cleaned through the fine and ultra-fine filters before it enters the main pump. Water must also flow through the Piranha Hard-Food Disposal and finally into the wash pump assembly. Clean filtered water then flows into the diverter system which directs it to either the lower spray arm or mid spray arm. -
