Water Softener - Fisher & Paykel DD24DCB7 User Manual

Setting up the water softener
Important!
Only some models (those with a letter 'H' in the model name) have a built-in water softener.
Models with water softener are not currently available in New Zealand and Australia.
Determine the water hardness in your local area
Your local water company will be able to provide you with information. Identify the setting you
require for your dishwasher from the water hardness table below. For example, if your water
hardness is 500ppm, then the water softener setting on your dishwasher should be 4. Refer to
the 'Preference options' section of your 'Quick start guide' for instructions on adjusting the water
softener setting.
