In the case of washing machines with a drain valve, a motorised 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 floor drain (with odour trap).
Thanks to an improved closing mechanism and a larger cross-sec-
tion, even the coarsest of soiling does not leave any deposits or
debris behind which could result in blockages. The drain valve can
also be operated manually to allow the suds container to be emptied
in the event of a power outage.
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 simultan-
eously.
The appropriate Miele installation kit (mat. no.: 05 238 090) is avail-
able to order from the Miele Customer Service Department or your
Miele dealer for venting an HT DN 70 pipe.
If the slope for drainage is extremely steep, the piping must be ven-
ted to prevent formation of a vacuum in the washing machine's
drainage system.
Slow or obstructed drainage or a backup of water in the washing ma-
chine drum as a result of undersized pipework can result in faults oc-
curring during programmes, which will result in fault messages ap-
pearing in the display.
Outflowing suds can be as hot as 95 °C. Danger of burning!
Avoid direct contact.
In machines with drain pump, the suds are drained through a drain
pump with a delivery head of max. 1 m.
The drain hose must be installed free of kinks for the suds to drain
freely.
There are the following options for draining the machine:
- Drain hose connected to a plastic drain pipe with a rubber sleeve
(there is no need to use a siphon)
- Drain hose connected securely to a sink with a plastic nipple
- Connected securely to a floor drain (gully)
If required, the hose can be extended to a length of up to 5 m. The
corresponding accessories are available from the Miele Customer
Service Department or your Miele dealer.
For a drain height of more than 1 m, a replacement drain pump for a
delivery head of max. 1.8 m is available from the Miele Customer Ser-
vice Department or from your Miele dealer.
