Infinite Level Control; Reset - Maytag LAT2300 Service Manual

As water enters the washer and the
level begins to rise, it
f1ow~
into the air
dome. This creates pressure on the
diaphragm through the air tube. When
the water reaches a predetermined
level, the pressure is sufficient to over-
come the pressure exerted on the
diaphragm by the pressure switch. As
the diaphragm rises, the electrical
contact arm is moved from "Fill" to the
"Run" position.
As water is drained from the washer
during spin, water is also drained from
the air dome, lowering air pressure in
the air tube. This allows the switch
contact to reset to the "Fill" position.
If the setting of MEDIUM or SMALL is
used, there is less pressure applied to
the tension bar, resulting in a
decreased amount of air pressure
required to trip the contact arm to the
"Run" position.

(Nol Compressed)
As the level indicator is raised, a
tapered cam on the back side of the
indicator comes in contact with an arm
which pushes against the diaphragm.
When the level indicator is pushed all
the way up (to a point where resistance
is met) the maximum pressure is
applied to the diaphragm and it will
take a full tub of water to overcome the
pressure applied to the pressure
switch, moving it from "Fill" to the
"Run" position.
The amount of water in the tub is
selected by moving the level indicator
to the desired level on the legend. The
large capacity model may be set on
Small, Medium, Large or any place
between. The extra large capacity
model may be set on Ex-Small, Small,
Medium, Large, Extra-Large, or any
place between.
When the level indicator is in the down
position, there is no pressure on the
diaphragm inside the pressure switch.
