3.0TECHNICAL OVERVIEW

3.1Chassis

The DishDrawer chassis is one complete assembly composed of 5 steel metal components locked together by a proprietry riveting process. The chassis exterior is made of a lacquered electrogalvanised material called Galvoclean.

Unlike most other dishwashers, the chassis assembly is a load carrying structure designed to impart stiffness to the product and to ensure deflection is minimised.

The feet of the Double cabinet are assembled into the chassis by means of four steel inserts which are clinched in place to form a permanent threaded connection.

The tub extends 520mm (2015/32”) out of the cabinet by travelling along two rigidly attached slides on either side of the tub.

3.2Drawer Fronts

Prefinished drawer fronts are formed from a painted, brushed or Iridium finish stainless steel blank. The drawer fronts are attached to the tub by means of formed hooks and two pins which are inserted through either side of the tub.

On the integrated model, the front panel supplied on each drawer is the mounting panel for the joinery finished drawer front. The joinery finished drawer front is supplied by the customer.

3.3Electronics

In the DD603/ DS603 (Phase 3) electronic controller the functions of controlling the motor as well as controlling the user interface console have been combined into a single 16-bit Micro Controller on the main printed circuit board.

This Micro controller also controls a transformerless 85w switchmode power supply. This power supply utilises a large dropping resistor on the heater plate in conjunction with phase control of the mains voltage in order to produce a variable voltage rail. From this the controller can supply voltages from 5V to 85V to the various components in the DishDrawer.

NOTE:- With power supplies of this nature all components regardless of supply voltage should be treated as live to earth. i.e = supply voltage.

The user interface comprises a printed circuit board for front controls and a touch switch panel for internal controls.

The electronics can connect to a computer service tool via an optical light pen for fault finding and product information.

The element is switched by one single pole relay. Overheat protection is effected by a short length of solder in series with the dropper resistor track on the heater plate. In an overheat situation this solder melts causing the power supply to go open circuit.

3.3.1Tub Home Sensor

A tub home sensor is used to determine when the tub is closed and it is safe to start a cycle. The tub home sensor consists of an inferred LED (sender) and an inferred transistor (receiver) mounted on the circuit board in the controller. Inferred light is transmitted from the LED through an optical light pipe to the right hand side of the tub. The inferred receiving transistor also has an optical light pipe leading from it out to the side of the tub. When the tub is closed the two light pipes are optically connected via a prism mounted in the trim on the side of the chassis.

DS603 I, DS603H, DS603IH, DS603M, DD603I specifications

The Fisher & Paykel DS603 is an innovative and highly efficient dishwasher designed to streamline the dishwashing process while providing exceptional cleaning performance. As part of Fisher & Paykel’s commitment to sustainable living and user-friendly design, the DS603 is packed with features that enhance both functionality and convenience in the kitchen.

One of the standout features of the DS603 is its unique Drawer Dishwasher design. Unlike traditional dishwashers, which have a single, large compartment, the DS603 offers two separate drawers that can be independently operated. This allows users to run smaller loads without the need to fill an entire dishwasher, making it ideal for smaller households or quick cleanups. Additionally, each drawer can accommodate different wash cycles, enabling users to tailor the washing process for delicate glassware or heavily soiled pots and pans.

The DS603 also incorporates a variety of wash programs, including Eco, Fast, and Heavy options, ensuring that dishes are cleaned thoroughly no matter the level of soiling. The Eco wash program is particularly notable, as it uses less water and energy while still providing superb cleaning performance, aligning with modern sustainability goals.

In terms of technology, the DS603 features SmartDrive™ technology, which utilizes a direct current motor that adapts to the load size and type, optimizing the wash performance while minimizing noise. This whisper-quiet operation makes it perfect for open-plan living spaces, ensuring that household activities continue smoothly without the interruption of loud washing cycles.

Another impressive characteristic of the DS603 is its adjustable racking system. Users can configure the interior of the dishwasher to accommodate a variety of dish sizes and shapes, from tall wine glasses to bulky pots. This adaptability enhances user convenience and maximizes the efficiency of each wash cycle.

Furthermore, the DS603 is equipped with a robust water filtration system that ensures clean water is used throughout the washing process. This not only improves washing results but also protects the dishwasher’s internal components from buildup and residue.

The Fisher & Paykel DS603 stands out as a versatile, eco-friendly appliance that combines cutting-edge technology with a user-centric design. Its unique dual-drawer system, customizable wash options, and efficient water use make it a top choice for modern kitchens, reflecting Fisher & Paykel’s dedication to creating quality home appliances that simplify everyday life while being kind to the environment.
