Water Level Switch Operation
The circuitry of the machine is designed
to put the switch in control of the water
mixing valve .QI the timer motor and drive
motor during various phases of the wash
cycle.
During the fill cycle, the switch makes a
circuit between its contacts 1 and 2 which
energizes the mixing valve circuit(s}.
When the switch is activated, it opens the
circuit between contacts 1 and 2 which
shuts off the water, and closes a circuit
between contacts 1 and
3
which ener-
gizes the timer motor and drive motor.

Testing the Water Level Switch
The water level switch can be accessed
as previously detailed in Section 3 under
Control Panel Disassembly. It can be
tested using an ohmmeter and executing
the following:
• When the tub is empty, ohmmeter
leads placed acmss terminals 1-2
should indicate continuity.
• When the tub is filled as per the
switch setting and corresponding
water depth (refer
to
Specifications
Section uncfer Water Level), terminals
1-2 should be open and terminals 1-3
should indicate continuity.
