Servicing The Dishwasher Dispenser
Assembly
Models DU920SFG, DP920SFG, GU940SFG,
GU960SFG and GU980SFG utilize a modified
draw bar to accommodate two wax motors
(Fig.
3-9) to activate the detergent and wetting agent
dispensers. The remainder of the dispenser as-
sembly is serviced in the same manner as all other
models.

Servicing the Soil Sensing System
The Soil Sensing System consists of a pressure sensitive switch connected to the dishwasher pump
base.
(Fig. 3-8) The system detects excessive amounts of food soils during the sensing portion of the
wash cycle and signals the electronic control board to either terminate the wash cycle and initiate
drain to flush soils from the system or skip certain parts of the heavy soil cycle.
The pressure switch is connected to the pump base through a plastic hose. The pressure switch is
secured to the bottom of the dishwasher tub by two (2) Hex- head screws.
