Water Regulations compliance in the UK
For the dishwasher to comply with the
Water Supply (Water Fittings) Regulations
and Bylaws, the supplied double check
valves must be fitted to the hot and cold
water connections between the stopcock
and the dishwasher water inlet hoses.
 Screw the non-return valve onto the
stopcock.
 Screw the water inlet hose onto the thread
of the non-return valve.
Connecting the drain hose
- The dishwasher drainage system is fitted
with a non-return valve, which prevents
dirty water from flowing back into the
dishwasher via the drain hose.
- The dishwasher drain hose should be
connected to a separate on-site drainage
system for the dishwasher only. If no
separate connection is available, we
recommend connecting it to a dual-
chamber siphon. The on-site connection
must be between 0.3m and 1m in height,
measured from the lower edge of the
machine. If the connection is lower than
0.3m, the drain hose must be placed in
an arc at least 0.3m high.
- The dishwasher is supplied with approx.
1.5m of flexible drain hose with an
internal diameter of 22mm. Hose clips are
supplied with the dishwasher.
- The drain hose must not be shortened.
The hose can be extended using a
connection piece to attach a further
length of hose. The drainage length must
not be longer than 4m.
- The drainage system must be able to
accommodate a minimum drainage flow
of 16l/min.
 Damage caused by incorrect routing.
Make sure that there are no kinks in the
drain hose and that it is not squashed or
stretched.
