FUNCTION DESCRIPTION

The washing action of the Point Voyager Dishwasher performs more work and maintains higher per-

formance with reduced energy consumption. This is accomplished with the following: 1) A redesigned

wash system using separate wash and drain pumps. 2) A soil sensor and thermistor which monitor

washing conditions. 3) An electronic control board which adjusts cycle functions to optimize washing

performance.

Wash/Rinse Function

1. The main wash water passes from the

spray arm nozzles, over the dish load and

into the sump assembly, where a number

of operations occur.

2. Water and soils pass through the course

protection grate at the top of the sump as-

sembly (2a) and then passes through the

foreign object protector (2b) into the main

wash pump inlet chamber (2c).

3. The water then passes through the chop-

per assembly where food particles are re-

duced in size so they can pass through

the water delivery system. (3)

4. Water is drawn through the impeller and

into the pump chamber. (4)

5. Here, 20 percent of the water is diverted

towards the soil accumulator. Food soils

in this water stream are captured by the

separation screen. (5)

6. Downstream restrictions limit the water

flow into the accumulator to 10 percent.

(6a) The remaining water is allowed to

rejoin the main wash flow by passing

through the separation screen. (6b)

7. This heavily soiled water is distributed

throughout the accumulator. (7) Soils will

remain trapped in the accumulator until a

drain or Automatic Purge Filtration event

takes place.

8. Since the water in the accumulator is un-

der some minimal pressure, it rejoins the

main wash water by flowing through the

accumulator screen into the tub. (8)

9. For this to occur properly it is critical that

the dishwasher be installed perfectly level.

10. Jets located on the underside of the lower

spray arm continuously wash down the ac-

cumulator screen to allow more soils to

concentrate. (10)

11. The remaining 80 percent of the wash

water will flow from the impeller through

the volute and up through the spray arms.
