When the solenoid is de-energized, the armature drops
down, closing the diaphragm main orifice. Water
continues to flow through the diaphragm bleed orifice,
equalizing the pressure and allowing the spring to push
the diaphragm down against the valve seat.

Water Temperature:
When the TEMPERATURE switch is set to Hot/Cold in
the wash cycle, the hot solenoid is activated and the
bleach solenoid is activated, for all except the last fill, in
rinse. For the last rinse fill the wash and bleach solenoids
are activated. When the TEMPERATURE switch is set
to Warm/Cold in the wash cycle, the hot and wash
solenoids are activated and the bleach solenoid is
activated, for all except the last fill, in rinse. For the last
rinse fill, the wash and bleach solenoids are activated.
When the TEMPERATURE switch is set to Warm/Warm
in the wash cycle, the hot and wash solenoids are
activated and the bleach solenoid is activated, for all
except the last fill, in rinse. For the last rinse fill, the hot
and bleach solenoids are activated.
When the TEMPERATURE switch is set to Cold/Cold in
the wash cycle, the wash solenoid is activated and the
bleach solenoid is activated, for all except the last fill, in
rinse. For the last rinse fill, the wash and bleach
solenoids are activated.

When the solenoid is energized, the resulting magnetic
field pulls the armature up into the valve guide. The
armature spring is compressed by this action. When the
armature moves up, it allows the water on the top of the
diaphragm to drain through the main orifice.
The diaphragm bleed orifice is much smaller than the
main orifice and will not admit enough water to
maintain pressure on the top side of the diaphragm.
Thus, as the pressure on the top of the diaphragm is
reduced to almost zero, the pressure on the bottom lifts
the diaphragm off the valve seat, allowing a full flow of
water.
