Water circulation
The circulation pump pumps water from the sump through a triple filter system
to the heater. When water enters the heater, a flow switch determines water is
present and allows the heater to be activated. As water flows, it’s heated until it
reaches the pre-set temperature determined by the cycle. Once it leaves the
heater, it flows through the sump into the upper and lower spray arms.
The aqua sensor, drain pump, NTC, Hi-limit and backflow valve are near the
heater under the sump. The aqua sensor senses water cleanliness –
dishwashers add or subtract rinses as needed. The NTC senses water
temperature. The Hi-limit shuts off the heater if the water gets too hot. The
backflow valve prevents waste water from entering the dishwasher.
