Water Level Control - GE WBVH6240 Technical Service Manual

Water Level Control

The water level control is installed on the cabinet
right side top brace. The water level control is
connected by a hose to an air chamber attached to
the bottom of the outer tub. The water level control
consists of 3 internal switches that monitor 4 water
level conditions.
• When the water level rises in the outer tub, air is
trapped in the air chamber.
• As the water level rises, the air pressure in the
air chamber increases.
• The increased pressure operates the 3 internal
switches.
• The washer has overfl ow protection and will
automatically pump out regardless of whether
the washer is on or off, as long as the unit is
plugged in. This action supersedes all other
commands.
• The 3 internal switches are identifi ed as foam,
main, and overfl ow. The 4 water level conditions
monitored are empty, foam, main, and overfl ow.

Water Level Control Operation
When the machine is empty, the foam switch is
closed and the motor circuit is disabled. When the
main wash cycle is activated, the fi ll valve begins
operating. The machine fi lls to the foam water
level, the foam switch opens, and tumble begins.
Water temperature is read by the thermistor and
fi ll valve percentage of operation (water tempering)
is calculated for the main wash. When calculated,
and/or when the load absorbs water, the tumbling
will pause. Fill will continue until the main water level
is reached (Adaptive fi ll), the main switch closes, and
main wash tumbling begins.
Water Levels
The foam water level is approximately 2
below the door opening and approximately
deep at the bottom center of the wash basket.
Foam Water Level
The main water level is approximately 1
below the door opening and approximately 2
inches deep at the bottom center of the wash
basket.
