For Best Results

Your dishwasher cleans by spraying a mix- ture of hot, clean water and detergent against soiled surfaces of dishes. When a cycle is started, the dishwasher fills with waterto about the level of the heating element. This water is

pumped through the rotating spray arms, drained through the filter system which re-

moves food and soil, and pumped back through the rotating spray arms. Soiled water is pumped out and replaced with clean water

during a cycle-the number of times depends on the cycle being used.

Load dishes so soiled surfaces face pow- erful spray from rotating arms.
