Active Vent - GE EDW4000 Technical Service Manual

water level is low, check the following:
• Flood switch, flood switch float, and float stem
- Flood switch should open when water level is
approximately 1/4 in. above the base (bottom)
of the float dome.
• Resistance through the water valve solenoid
coil - Check from yellow wire at flood switch to
white/red wire at door interlock switch (Es-
cutcheon keypad assembly must be removed,
refer to
Escutcheon Keypad Assembly
• Clogged screen in water valve.
Caution: After removing the screws from the
escutcheon keypad assembly, the assembly is
still attached to the control module by 2 ribbon
cables. Dropping or rough handling of the
escutcheon will cause the ribbon cable to tear, and
the entire escutcheon keypad assembly will need
to be replaced.

Active Vent

The active vent helps to reduce the noise level and
heat loss when in the closed position. The control
module supplies +/- 12 VDC to the motor. The
control module reverses polarity to drive the motor
in a clockwise or counterclockwise (open or
closed) direction. The vent is closed during the
wash cycle and open during the drying cycle
(heated and non-heated) and when the unit is not
in use. If the vent is closed and the door is opened
during the wash cycle, the vent will open. When
the door is closed again, the vent will remain open
for seven (7) seconds, then close again to finish
the cycle.
It is normal for steam to come through the active
vent during the dry cycle.
The active vent can be opened and closed using
the service mode. Refer to the
chapter.
The active vent can be accessed by removing the
escutcheon keypad assembly (see
section).
Keypad Assembly
IMPORTANT: When reassembling, the active vent
flapper must be closed before the escutcheon
keypad assembly is installed. Close the active vent
flapper by turning the worm gear by hand. Failure
to do so will cause a misalignment and an
increase in noise level.
