Adding rinsing agent
The dispensing of rinsing agent in
the final programme programme via
DOS 2 has to be activated by a
Miele service technician.
Rinsing agent is necessary to ensure
water does not cling and leave marks
on items, and to help items dry faster
after they have been washed.
Because residues of rinsing agent
remain on the surface of items after
they have dried, it is important to check
the suitability of the rinsing agent being
used.
Rinsing agent is poured into the
storage reservoir, and...

to use a citric acid based
neutralising agent.
