If you have a household water softener installed, use the quantities recommended for water with a hardness under 100 ppm/6 gpg, irrespective of the water hardness in your area. See also section ‘Water softener’.

  • If your water hardness is above 625ppm/36 gpg, we highly recommend you completely fill the main detergent dispenser for all programs (except Rinse) and the secondary dispenser for heavily soiled loads. The rinse aid setting should be at 5.
  • If your water hardness is above 625ppm/36 gpg, the wash performance of your dishwasher will decline.
