Upper Spray Arm; Lower Spray Arm; Filter; Drain Pump - Electrolux GLDB957JB series Service Manual

Upper Spray Arm

The upper spray arm hangs from a bracket that is
snapped to the bottom of the upper rack. The water is
supplied to the arm with a nozzle and funnel
arrangement. The nozzle is located at the top of the tub
and the funnel is located directly below it and directs
water into the arm. All the spray jets but three (3) face
up.

Lower Spray Arm

The lower spray arm rotates on the lower spray arm
support. It has two functions, washing the dishes and
cleaning the filter. The jets located on the top of the arm
clean the dishes and propel the arm. The three (3) jets
located on the bottom of the arm are aimed to flush the
soil on the filter toward the glass trap and soil director.

Filter

The filter consists of two parts, an inner basket
constructed of fine polyester mesh, and an outer filter of
stainless steel.

Drain Pump

The drain pump has only one function, to remove water
from the dishwasher. The drain pump is driven by a 1/
25 th HP drive motor. It consists of three (3) functional
parts; a pump cover, impeller and armature, and stator.
The quiet cavity and impeller cavity are connected by a
hose underneath the sump. This connection between
the two cavities allows both cavities to be drained.
DRYING SYSTEM
At the start of the dry cycle, a vent opens at the upper
left hand corner of the door allowing the warm moist air
to escape out the front of the control panel. Dry room air
is drawn into the dishwasher tub through an opening
across the bottom of the door. If the heated dry cycle is
selected, the heating element raises the temperature of
the air to increase the evaporation rate and the flow rate
of the air through the dishwasher. These models
incorporate the use of a small motor and centrifugal
blower to accelerate the movement of air through the
dishwasher.
