  • Page 10 One-Point Information About Linear Water Level When “Standard”, “Soak” , “Memory”,"Heavy","Delicate" or "Softener" is set, the weight sensor automatically sets the most suitable water level for the washing load on a linear basis to save water. Setting is made based on the 4-levelled water level for manual setting. For example, when the detected washing load is 5.0kg, the most suitable water level of 67.3L is automatically set by proportional calculation between the first level of 82L for washing load of 7.0kg and the second level of 60L for washing load of 4.0kg.
