Drain valve

8
If there is no hot water supply at the installation location, the inlet
hose for hot water must also be connected to the cold water supply.
An additional Y-piece is required in this case. Cold water consump-
tion increases accordingly to account for the missing hot water in-
take.
For functional and technical reasons it is not possible to operate
the machine exclusively with a hot water connection.
Even if a hot water connection is present, the washing machine
must be connected to a cold water intake.
A motorized dump valve is used to drain the machine. An HT DN 70
angle connector can be used for draining the machine directly into
the waste water system (without a siphon) or into an on-site gully
(with odor trap).
A vented drainage system is vital for unimpeded drainage.
If several machines are connected to a single drain pipe, this
should be sufficiently large to allow all machines to drain simultane-
ously.
The appropriate Miele installation kit mat. no.: 05 238 090 is avail-
able from Miele or Miele Technical Service for venting an
HT DN 70 pipe.
If the slope for drainage is extremely steep, the piping must be
vented to prevent formation of a vacuum in the machine's drain
system.
Slow or obstructed drainage or a backup of water in the drum as a re-
sult of undersized pipework can result in faults occurring during pro-
gram sequences, which will result in error messages appearing in the
display.
 Risk of burning due to hot suds.
Outflowing suds can be as hot as 203°F (95°C).
Avoid direct contact.

Dispenser pump connections

Up to 12 dispenser pumps can be connected to the washing ma-
chine.
