The Wpro regenerating salt (484000008555) is designed to maintain the efficiency of your dishwasher by regenerating the water softening device. By reducing the mineral content of the water, these crystals prevent limescale deposits from forming on both the internal components of the machine and your glassware, ensuring a cleaner finish. This 1 kg supply is specifically recommended for use with Whirlpool, Hotpoint, Bauknecht, Indesit, and KitchenAid appliances. You can simply fill the salt container whenever the refill indicator light appears or according to your machine's specific instructions. Because it optimizes overall performance, it is a practical choice for households in hard water areas looking to protect their appliance's longevity. For safety, please ensure the box is kept out of reach of children.
