Miele G 7804 operating instructions Water softener, Setting the water softener

Water softener

To avoid the build-up of calcium deposits on glassware and the machine, the water may need to be softened (where the supply hardness exceeds 107 ppm CaCO3).

To ensure a steady supply of soft water, the water softener must always be:

1.correctly set (programmed) and

2.regenerated with salt as soon as the "Recharge Softener" indicator illuminates.

The water softener should be set to correspond with the water hardness upon installation of the machine.

Your local water authority can advise you on the water hardness in your area.

Setting the water softener

The machine is set at the factory for a water hardness setting of 19*, corresponding to 339 ppm CaCO3. If your water supply is harder or softer than this, the setting of the controls should be changed.

Where the water hardness fluctuates e.g. between 160 - 310 ppm, always program the machine to the higher value, 310 ppm in this example.
