Drying System

The Drying system consists of a Fan/Vent assembly,
Heater, and Air Baffles. The way the systems per-
forms is; as the dry portion of a wash cycle is
reached the control activates the heater, if selected,
and opens the vent door, located in the top right rear
of tub, this allows the vent fan to draw in outside air
resulting in hot air being forced out the bottom of the
outer door panel. See Figure 16

Fan/Vent assembly

Figure 17
Fan/Vent assembly located top right rear of tub. The
vent door, normally closed, is opened by a 12 VDC
solenoid also mounted in the assembly. There is an
optical sensor to indicate to the dishwasher control
that the vent door is properly closed until it is to be
opened. See Figure 17 & 20
If for any reason this door is not closed, the control will
attempt to close the door 5 times if it continues to fail a
failure code will appear in the display. The dishwasher
will not operate until this condition is corrected.

The vent fan starts as soon as the vent door is
opened and turns at 3500rpm. The motor is pow-
ered by 12 VDC with a frequency generator to
indicate to the control fan speed. If for any reason
the Fan/Vent assembly would get disconnected, a
failure code will appear in the display on the front of
the door and the dishwasher will completely shut
down. The dishwasher will not function without this
assembly.
