3.5 Lid System
The lid is a single piece of polymer plastic with a diaphragm/seal co-injection moulded into it. The centre of the
lid can move relative to the seal. Each side of the lid is clipped into a yoke, which is in turn connected to a worm
drive lid actuator assembly containing a small brushed DC 24 volt motor.
When the product is rst plugged in and switched on at the wall, the lid motors are powered up to ensure that
the lid is fully raised.
3.5.1 When Activated
At the beginning of the wash cycle, both lid motors are powered up to pull the lid down onto the tub ange in
approx 2 -3 seconds. The lid remains down for the duration of the wash and is only lifted when the DishDrawer
beeps to signal the end of the cycle, or if the cycle is paused to gain access to the tub.
3.5.2 During a Power Failure
If power to the DishDrawer™ fails with the lid down, the tub can still be forced open manually if access is required.
It is very dicult however to close the tub again without raising the lid. The lid actuators can be wound up
manually with the tub fully removed. Failure to raise the lid before closing the drawer can result in the lid seal
being damaged.
3.6 Tub
The tub is the main cavity where all the wash activity occurs. The tub is a polymer plastic receptacle that houses
the basket ware which includes adjustable cup racks and basket with fold down tines along with a wash pump
and spray arm at the base. The tub also has guide vanes around its walls which direct falling water from the wash
cycle in a clockwise direction around the lter plate. This clears the lter plate of food particles and washes them
into the sump where they are trapped by the drain lter or pumped out during the drain cycle.
3.7 Filling
3.7.1 Water Inlet
The tub of the DishDrawer™ lls by a single water inlet hose. Hot water connection is recommended for USA and
Japanese products, and cold water connection recommended for the Australasian, UK and European products.
From the connection to the water supply tap in the kitchen, the inlet hose enters the cabinet of the dishwasher at
the base, onto a dual water valve.
Each tub is supplied water independently via one of the dual valve coils and a ll hose that runs through a
customised link assembly at the back of each tub and travels along the base of the tub under the wiring cover
to the front. At the front of the tub, the ll hose connects to the water softener (if tted) then to the detergent
dispenser which directs water into the tub.
Depending on the market and cycle chosen, the product lls through the pre-rinse section of the dispenser for
the pre-rinse cycles and secondly through the main wash section for all other cycles.
In a double product the controller allows only one inlet valve to operate at a time. This has been done to reduce
EMC emissions, the top tub has priority.
Note: This restriction does not apply in diagnostic mode.
