3 MODEL NUMBER LOCATION & IDENTIFICATION 3.1 Model Number & Product Code The model number and product code is shown on the product data plate, which is located on the front of the chassis trim. The product code is a specific code relating to that product, which if ordering spare parts, you need to use the product code to ensure you get the correct parts manual, as some parts for the Phase 9 DD are specific for this model.
4 TECHNICAL OVERVIEW 4.1 Chassis The DishDrawer chassis is one complete assembly composed of 5 steel metal components locked together by a proprietary riveting process. The chassis exterior is made of a lacquered electro-galvanised material. 4.2 Drawer Fronts Prefinished drawer fronts are formed from steel blanks. The drawer fronts are attached to the tub by means of formed hooks and two square pins that are inserted through either side of the tub.

4 TECHNICAL OVERVIEW 4.5 Tub Home Sensor The tub home sensor determines when the tub is closed. The tub home sensor consists of an infrared transmitter and receiver mounted on the right side of wash controller. When the tub is fully closed, infrared light is transmitted from the sender through a light pipe on the side of the tub, through a prism mounted in the chassis trim, then back through the other light pipe to the receiver.
4 TECHNICAL OVERVIEW 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 TECHNICAL OVERVIEW 4.12 Filling with Water The wash tubs of the DishDrawer fill by a single water inlet hose. Hot water connection is recommended for the USA market only, while cold water connection recommended for the AU & NZ markets. From the connection to the water supply tap in the kitchen, the inlet hose enters the cabinet of the dishwasher at the base, into a dual water valve.
4 TECHNICAL OVERVIEW 4.12.2 Amount of Water The tub fills with approximately 2.8 litres (3/4 gallon) of water. The phase 9 model uses a new HYBRID filling system. This new filling system works slightly differently to the older dynamic filling system by looking for a good consistent prime over a LONGER time period (about 15 secs) and looks for this over a 40 sec period.
4 TECHNICAL OVERVIEW 4.13.2 Heating the Water The heater plate is situated below the water duct cover. The water is passed over the heating element during the wash cycle via the duct. The heated water is then picked up by the motor rotor and distributed to the wash load via the spray arm.
4 TECHNICAL OVERVIEW 4.15 Water Softener ( some markets only) The Water Softener uses a softening material (resin) to prevent most of the elements that cause hard water from being present in the wash water. The resin can only treat a limited amount of water before it needs to be regenerated. Regeneration is achieved by pumping salty water (brine) through the resin, and flushing away the hard elements to the drain.
4 TECHNICAL OVERVIEW 4.16 WiFi Module Ph9 is Wi-Fi capable. It has a Wi-Fi module integrated to the bottom of the top tub. The Wi-Fi module enables the product to be controlled using a phone App (Smart HQ). The app provides the following functionalities: Select a cycle Select a modifier Start/Pause or cancel a cycle...
