LID LATCH
A lid latch mechanism holds the dishwasher lid
closed during the cycle. A wax motor and trip
arm assembly are mounted alongside the lid
mechanism to open the lid at the end of the
cycle. Once the dishwasher has reached the
final rinse, the wax motor is energized for the
final two minutes. As the wax motor reaches its
full extension, it moves the attached release
arm to disengage the lid latch, and allow the lid
to pop open. The opening of the lid, coupled
with the high water temperatures, causes the
dish load to “flash dry,” due to the sudden
venting of the heat and steam in the dish-
washer. This is the only means of drying. No
heating element is provided for drying dishes.
An inline water heater is used to heat water
during the cleaning cycle. The heater is located
between the sump and the wash pump. Water
from the sump flows through the heater, into
the wash pump inlet, and is then recirculated
through the poppet valve into the tank.

INLINE WATER HEATER
OPTIONAL AUXILIARY WATER HEATER
An auxiliary water heater can be installed to
boost the water temperature for immediate hot
water at the beginning of the cycle. The auxil-
iary water heater consists of a 2-1/2 gallon
tank, and a 1100 Watt heating element. The
water heater heats the water to a temperature
of 165°F / 74°C to provide a shorter wash cycle.
