The LS 603 features a classic rotary dial system. To start a wash, you must turn the knob clockwise to the desired program number.

Program 1 (Heavy Duty): Best for pans and heavily soiled dishes; includes a pre-wash.

Program 2 (Normal): The standard daily cycle for mixed loads.

Program 3 (Eco/Light): Uses less water and lower heat for lightly used plates.

Program 4 (Rapid): A quick rinse and wash for items needed immediately.

Program 5 (Soak): A cold rinse to prevent food from drying while waiting for a full load. 🧂 Essential Maintenance: Salt and Rinse Aid

For the LS 603 to clean effectively, two reservoirs must be kept full:

Water Softener (Salt): Located at the bottom of the tub. Unscrew the cap and use a funnel to add dishwasher salt. This prevents limescale buildup on the heating element.

Rinse Aid: Located inside the door. This ensures dishes dry without water spots. Adjust the dial (1–6) inside the dispenser if you notice streaks (too much) or droplets (too little). 🧼 Loading and Filtration The LS 603 manual strongly emphasizes regular cleaning

Efficiency depends on how water moves through the spray arms:

Spray Arms: Ensure the holes are not clogged with seeds or debris. They can usually be unsnapped and rinsed under a tap.

Filter System: The LS 603 uses a three-stage mesh filter at the base. Rotate the central cylinder counter-clockwise to remove it. Clean this weekly to prevent odors and drainage issues.

Rack Logic: Place tall items on the perimeter of the bottom rack so they don't block the detergent dispenser door from popping open.

💡 Quick Pro-Tip: If the dishwasher isn't draining, check the "drain hose" for kinks and ensure the kitchen sink's U-bend isn't blocked. To help you get the most out of your machine, Is it not heating the water? Are the dishes coming out cloudy or wet?
