WATER SOFTENER (SOME MODELS ONLY) IMPORTANT! ● Only models 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. ● Models without built-in water softener: If living in an area with very hard water, consult a plumber on installing a household water softener. Setting up the water softener 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.

If your water hardness is above 625ppm/36 gpg, the wash performance of your dishwasher will decline. ● You may hear some unusual noises when the water softener is in operation, this is normal. 28
