Inadvertently filling the sale reservoir with cleaning agent will damage the water softener.
Before filling, make sure that you are using reactivation salt.
12. Test the water hardness and activate softener if necessary
Note: If not using water softener, please set and save the water softener setting at 0.
Before using the machine for the first time the water softener should be programmed according to the hardness
of the incoming water. You can determine water hardness with a simple test kit or by contacting your local water
authority.
Note: the G 7881 is set at the factory for a water hardness level of 19 gr/gal (340 ppm). If your hardness level is
other than the factory default then the G 7881 must be reprogrammed to the proper setting. Reference the Water
Hardness Table below for the correct value.

A. Filling the salt reservoir:
Only Miele approved reactivation salt should be used in the G 7881.
Do not use other types of salt, e.g. table salt, agricultural, or gritting salt. These could contain
components which are insoluble in water and could damage the water softener. If in doubt,
consult Miele's Professional Department.
The salt reservoir holds approx. 2.5 kg of salt.
