Active Vent

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 section).

•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.

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 Service Mode chapter.

The active vent can be accessed by removing the escutcheon keypad assembly (see Escutcheon Keypad Assembly section).

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.
