Recommended using soft water for better results. Hard water contains impurities that can
reduce the washing performance. You will need to soften the water if the supplied water is
harder than 1.0 mmol/L (6 °d – German scale).
• To soften the water, you need dishwasher-specific salt and configuration of the water
hardness level according to your area. For more information about the water hardness
level in your area, contact your local water department.
• If the hardness level of the supplied water supply is unsteady, set the dishwasher to
the highest measurement. For example, if the water hardness reading ranges from
6.7 mmol/L to 9.0 mmol/L, set the dishwasher to 9.0 mmol/L.
• The dishwasher's default water hardness level is 4 (5.5-7.0 mmol/L). If this setting
matches the water hardness level in your area, you do not need to change it.
• Regeneration will be operated in dry phase with an additional 2.3-2.7 L of water being
used and 22-27 minutes taken for the cycle. The energy used may be increase however
this should be by an insignificant amount.
