Special Feature

Soil Settler

This model is equipped with a soil settler system. The inlet to the soil settler funnel is located to the

right and just behind the lower spray arm assembly.

(Fig. 1-1)

Since this inlet is located in an area that is relatively free of water turbulence, food particles washed

from the dishes can collect in this area and fall through the funnel and accumulate in the collector.

(Fig.

1-2)

Food particles continue to collect as long as the dishwasher is in the Wash mode.

When the Wash cycle is finished, the dishwasher will reverse the direction of the motor and enter the

Drain mode. Water is pumped into the port at the bottom of the soil collector during the Drain cycle

causing the ball in the collector to rise against the opening in the bottom of the funnel. Water flows

through and out of the collector through the top port and into the drain line.

(Fig. 1-3)

Food particles

collected during the Wash cycle are carried out with the drain water. When the Drain cycle ends and

the pump stops running, the ball settles to the bottom of the collector.
