Hotpoint CalBlock + Replacement cartridge

The Wpro professional CalBlock+ cartridge offers full protection for your appliances. It includes polyphosphate crystals and a mechanical filter that effectively protect the inner parts of your machines (heating element, electric valve, tubes, filters) from limescale and other sediments like rust or sand. It contributes to reduce the hardness of the water, ensuring detergent savings and better washing performances. It works at its best at low temperatures (up to 60°C). Replace the cartridge every 4 to 6 months for best performance. It is suitable for all washing machines, washing dryers and dishwashers.
