4.10 Drain Filter
The drain filter is a combination of a large catchment area
for solid food pieces and a fine mesh for straining wash
water, it is designed to minimise soils re-depositing on the
wash load.
The Drain filter assembly can be separated into 2 pieces for
fine cleaning, but we recommend rinsing out as one piece.
4.11 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 first plugged in and switched on at the wall, the lid motors are powered up to
ensure that the lid is fully raised.
4.11.1 When Activated
At the beginning of the wash cycle, both lid motors are powered up to pull the lid down onto the tub
flange 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.
4.11.2 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 difficult 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.
