Hard water contains high levels of minerals—mainly calcium and magnesium. These minerals aren’t harmful to your health, but they can seriously interfere with the effectiveness of your dishwasher. When hard water meets dishwashing detergent, it forms mineral deposits that can:

Prevent the dishwasher tablet from fully dissolving
Leave chalky white spots on glassware

B. Use Rinse Aids or Water Conditioners:

C. Switch to Tablets Designed for Hard Water:
