Drain Pump; Speed Control; Motor - Electrolux 6000 series Service Manual

the excess water to backup into the channel across the
rear of the dispenser and flow into the tub.

Drain Pump:

The drain pump is mounted to the bottom plate of the
washer behind the access panel. It operates on 120
VAC and is controlled by the control board and pressure
switch. The pump out specifications of the drain pump
vary from 12 G.P.M with a 3 foot standpipe height to 5
G.P.M. with a 8 foot standpipe height.

Speed Control:

The speed control board is mounted to the base plate of
the washer in the left rear corner of the washer. Thespeed
control board controls the following operations:
Note: The control board is the board that is
mounted in the console and the speed
control board is the board that is in the left
rear corner of the washer.
1. The speed of the drive motor by converting input line
to neutral single phase 60 Hertz voltage, to a varying
frequency, three phase output voltage from zero to
300 VAC. By varying the amount, frequency, and
polarity of the voltage and comparing the input from
the tachogenerator on the drive motor, the speed
control board can operate the drive motor at a
preprogrammed speed and direction.
2. The balance of the load in the washer during the
spin cycle by converting the sine wave from the
tachogenerator to square waves and comparing the
distance between the square waves.

Motor:

The motor is mounted to the bottom of the outer tub.
S p e e d
The motor is an induction, three phase AC motor that
varies speeds when the voltage from the speed control
board varies in frequency and amount. The motor has a
tachogenerator that inputs the speed of the motor to the
speed control board.
