Miele W1986 - Manual (Page 46)

The washing machine can be
connected to a potable water supply. A
non-return valve is not required, unless
required by building code.
The washing machine has
1
/
2
" pressure
hoses with
3
/
4
" female hose thread
connections. If there is no water
hookup, contact a plumber to install a
connection. Make sure that the sealing
ring is seated properly on the hose
connector.
Only replace the hose with a genuine
Miele hose or with a hose able to
withstand up to 145 psi (10 bar)
pressure. The water valve connector
must also be able to withstand 145 psi
(10 bar).
To protect the inlet valve, the two
filters - one at the pressure hose /
valve connection and one at the inlet
connection to the solenoid valve -
must be in place during use.
