    If you live in an area with hard water, you may notice white marks being left on washed items, particularly glassware. Correct use of dishwasher salt and rinse aid can help with this issue (also see the “White or cloudy marks…” topic).

    Always check the user manual for any recommendations on your specific dishwasher but the steps below will give you some general guidance.
  • 1. To deliver good washing results, your dishwasher needs soft water (water with low amounts of lime), otherwise white limescale can get deposited on the items you are washing and on the inside of the dishwasher itself.
  • 2. Tap water in hard-water areas must be softened (your water supply company may be able to tell you how hard the water is where you live). The water is softened with special ‘dishwasher salt’ (also known as ‘regeneration salt’) and this works inside the water softening system of your dishwasher.

    The amount of salt needed depends on how hard your your tap water is; the salt is to added by filling a special compartment (normally in the bottom of the dishwasher) and many dishwashers will have adjustable settings for the amount of salt used during each wash, check your user manual for precise details on your specific appliance.
    As your pour the salt into the compartment, water will flow out: fill the salt compartment to the top.
  • 3. Correct use of rinse aid can also help with hard-water issues. Your dishwasher will have a special compartment (normally on the inside of the door) for this to be added, along with adjustment for the correct amount to be used in each wash; check your user manual for precise details on your dishwasher.
    Even if you use detergents with integrated rinse-aid additive, the use of separate rinse aid is still recommended for certain levels of hard water.
