Hard water situations

If you live in a hard water situation, we recommend the installation of a household water softener to improve the water quality, detergent effectiveness and prevent the build up of calcium deposits on dishes and in the DishDrawer®.

Certain brands of dishwasher detergent contain varying quantities of phosphates, which help soften water. We suggest you use a detergent with high phosphate content to improve the wash. The detergent compartments need to be completely FULL and rinse agent is used with its setting fixed at 5.

We recommend the use of a dishwasher cleaner/descaler whenever you notice a build up of calcium deposits in your DishDrawer®.

After you have used the dishwasher cleaner/descaler you must run another wash program with detergent to prevent damage to the DishDrawer®.

Soft water situations

If you live in an area of naturally soft water or your household water is softened, avoid using too much detergent in your DishDrawer®. An excess amount of detergent is very aggressive on glassware and may cause irreversible etching.

Etching is a chemical deterioration that occurs on the surface of glassware when it is subjected to high temperatures, too much detergent and/or soft water situations. Etching is caused by a combination of very hot water, which causes the detergent to become very aggressive, but because the water is soft, there are no water hardness mineral ions for the detergent to bind to, so it extracts mineral ions directly from the glass.

Etching looks like rainbow colored film, as the glass is subjected to further washing the surface will eventually appear opaque. This type of etching is irreversible.

To prevent further etching from occurring on glassware use less detergent (follow the recommended detergent quantities in the User Guide for soft water situations), and ensure the dishwasher is not overloaded, so water can reach all the dishes during the wash.

DS603 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.
