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

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.

HeatingElement
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
agent will improve the water sheeting action and
drying performance.

It is normal for the stainless steel tub and inner door
panel to retain water droplets even though the dishes
are dry.
