Rinsing System - Electrolux Compact Service Manual

Rinsing system

The function of the rinsing system is to wet the
dishes loaded into the machine.
The electric motor of the circulation pump is
delivered with the impeller fitted to it. Half the
pump casing forms part of the plastic chassis,
and the other half is bolted in position inside the
washing chamber.
This arrangement ensures, that the joint between
the two halves of the pump casing is inside the
washing chamber.
An O-ring provides the seal between the motor
assembly and the chassis.
The rating of the electric motor is 60 watts(50 Hz)
or 80 watts(60 Hz) and the pump circulates around
30 litres per minute.
The electric motor needs assistance at the instant
of starting, which is provided by a starting
capacitor.
The motor mounting is very important to the sound
level. Since the movements of the motor are a
minimum at the centre, the motor is secured to a
rubber mounting in the centre, at the rear end of
the motor.
To ensure that no vibrations will be transmitted
from the motor to the base plate, a plastic foam
spacer strip is fitted to the bottom of the chassis.
The pump casing half which is inside the wash-
ing chamber also contains the spray tube bear-
ing with a stainless steel shaft.
The underside of the spray tube is fitted with a
seal ring to minimize leakage.
The shape and orientation of the holes in the spray
tube are such that the dishes furthest away in the
corners of the machine will also be effectively
washed.
The spray tube rotates anti-clockwise at a speed
of 10 - 20 1/min.
If the speed is too high, the dishwashing results
will be poor, and if the speed is too low, the spray
tube may stop al-together.
The pressure in the spray tube is just over 0.2 kg/
cm². The spray tube is retained by a ceramic nut
with a left-hand thread, to en-sure that the rotation
of the spray tube will not cause the nut to unscrew
itself. This means that the nut must be un-screwed
in the „wrong“ direction.
