Circulation Pump and Motor

           

he dishwasher must be removed from its

installation to gain access to the circulation pump

and motor. The circulation pump can be activated

using Test Mode

. Refer to schematic or strip circuit

for motor resistance value.

Before removing the circulation pump, remove the

water from the sump with a syringe.

It is important to remember the motor does not start

immediately when the dishwasher cycle has

started. If the motor hums, but will not start, make

certain the pump impeller is free from obstruction

and the motor shaft can turn freely.

The terminals on the induction motor are labeled



L1 and /5IFNPUPSJTUIFSNBMMZQSPUFDUFEJOUFSOBMMZ



through the L1 side. The wiring connector is blue to

match the wire leading to the motor. It is designed

to fit only one way on the terminals. Make certain

the connector is fully seated when installing.

Heating Element

The heating element can be activated using TEST

Mode.



The dual-wattage heating element produces 850

watts during wash, to help heat the water, and an

effective wattage due to cycling of 541 watts during

the dry cycle.



Water inlet temperature must be at least 120 F for

proper drying. Lower water inlet temperature will

prevent proper convection air movement and

increase drying time substantially.



If the problem is that the dishes are not drying

correctly, don’t overlook the rinse agent. A rinse

panel to retain water droplets even though the dishes

are dry.
