Personal Injury Hazard
Heater
Refer to the cycle chart on the reverse side to
determine when the heater is on during the
wash cycle. The heater cycles ON and OFF for
brief periods during the drying cycle.
Voltage checks of the heater should be made in
the dry portion of the service test mode.
The drain hose must have a loop at a
minimum
height of 32 inches
in order to insure proper
drainage.
Pump Assembly
The pump assembly is driven by a synchronous
motor. The motor drives a pump which supplies
100 percent filtered water
Draining is accomplished by using a small
separate synchronous drain pump mounted to
the side of the sump. The drain pump is
connected to the main pump by a small rubber
hose. The drain check valve is located at the
discharge end of the drain pump. The drain hose
is attached by a clamp to the discharge end of
the drain pump.
Detergent and Rinse Aid Dispenser
The detergent and rinse aid dispenser is a one
piece component consisting of a molded
detergent cup and a built-in rinse aid dispenser.
The detergent cup has a spring loaded cover
and the rinse aid dispenser has a removable
cover.
Liquid rinse aid is added to the dispenser up to
the fill line indicator. The amount of rinse aid
released can be adjusted by turning the arrow
indicator from one, being the least amount, to
four, being the greatest amount.

Motor trips out on internal thermal
overload protector.
Dishwasher runs but will not heat.
Detergent cover will not latch or
open.
Dishwasher will not pump out.
Dishwasher will not fill with water.

The water on the dishes is evaporated into drier
air and the venting process continues. The
heating element is turned ON and OFF during the
entire drying cycle.
