Priming The Dispenser Pumps; Internal Water Softener (Special Equipment); Lack Of Salt Display; Filling Regeneration Salt - Miele professional PG 8172 Mode D'emploi

Internal water softener (special equipment)

Procedure:
 When handling chemicals, observe the safety notes and the dosage recommendations on
the packaging.
 Wear protective clothing, protective gloves and protective goggles when handling chemicals.
Danger
 Do not mix different detergents.
 Remove the suction tube from the container and place it in a water-filled container.
 Rinse the dosing tubes and the detergent dispenser pump with water. To do this, use the prime dispenser
pump function several times ( 10). The frequency depends on the length of the dosing tubes.
 Place the suction tube in the new detergent container.
 Use the prime dispenser pump function several times ( 10), to replace the water in the dosing tubes
with detergent.

5.5 Priming the dispenser pumps

Dispenser pumps must be primed if air gets into the dosing tube because the containers were not
exchanged or refilled in time ( 10).
6 Internal water softener (special equipment)
By softening the inlet water, limescale build-up in the machine and on the dishes is avoided. For the internal
water softener to work correctly, the salt container must be filled with regeneration salt.
INFO At the commissioning of the machine the authorised service technician measures the water
hardness and saves it in the machine's electronic control unit.

6.1 Lack of salt display

A pictogram appears on the screen when an empty salt container requires refilling. The
display disappears after filling the salt container, as soon as approx. 3 wash cycles have
been completed and part of the salt has been dissolved.

6.2 Filling regeneration salt

Possible risk of damage to the water softener
Chemicals such as detergent and rinse aid inevitably lead to damage to the water softener. Fill
only with regeneration salt or pure evaporated salt.
Caution
Possible malfunction of the water softener
Do not fill with other salts (e.g. table salt cleaning or de-icing salt). These can contain water-
insoluble components. Fill only with fine-grained salt (max. 1 - 4 mm grain size).
INFO Because of their size, salt tablets are not suitable.
 Proceed in accordance with Figures A1 to A5.

IMPORTANT

Figure A2 is only relevant for the first filling.
Risk of rust formation in the filling area
Immediately after filling, start a wash cycle to rinse off any salt residue.
