Escutcheon Keypad Assembly - GE Profile PDW8200 Series Technical Service Manual

2. If the water valve is not operating properly or
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 sole-
noid coil - check from yellow wire at flood
switch to white/red wire at door interlock
switch (escutcheon keypad assembly
must be removed, see Escutcheon
Keypad Assembly). The resistance
should be between 750 Ω and 1200 Ω.
• 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 escutch-
eon 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 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 (see
Service Mode).
The active vent can be accessed by removing the
escutcheon keypad assembly (see Escutcheon
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 in-
crease in noise level.
