Adding and dispensing process chemicals

Neutralizing agent
Neutralizing agent is dispensed via an external DOS module. DOS
modules are fitted by Miele Service and can be retrospectively fitted
at any time.
Neutralizing agent (pH setting: acidic) neutralizes any residues of
alkaline cleaning agents on the surface of the load and protects the
wash chamber from deposits and discoloration.
Neutralizing agent is dispensed automatically in the
Rinse
phase after
the main wash (see Program charts). The neutralizing agent container
must be filled and the dispensing system vented for this to occur.
In the
Inorganic
program neutralizing agent is dispensed additionally
for an acidic pre-wash.
Refilling
neutralizing agent
Place the neutralizing agent container (red marking) on the open
cabinet door or on a surface which is robust and easy to clean.
Unscrew and remove the suction lance. Place the suction lance on
the
open cabinet door.
Replace the empty container with a full one.
Push the suction lance into the opening of the container and screw
it on tightly. Observe the colour coding.
Wipe up any spilled process chemical thoroughly.
Place the container on the floor next to the machine or in an
adjacent cabinet. Make sure that the dispensing hose is not kinked
or trapped.
Vent the dispensing system as necessary (see "Settings
/ Venting
DOS").
