John Lewis JLDWS1208 - Manual (Page 29)

The water inlet hose must not be kinked,
crushed, or entangled when it is being
connected.
The appliance features inlet and drain hoses
which can be turned either to the left or the
right to suit the installation by means of the
locknut. The locknut must be correctly
fitted to avoid water leaks. (Attention!
NOT all models of dishwashers have inlet and
drain hoses provided with a locknut.)
If the appliance is connected to new pipes or
pipes which have not been used for a long
time, you should run the water for a few
minutes before connecting the inlet hose.
DO NOT use connection hoses which
have previously been used on an old
appliance.
This appliance has been fitted with
safety features which will prevent the
water used in the appliance from
returning back into the drinking water
system. This appliance complies with
the applicable plumbing regulations.
Water drain connection
The end of the drain hose can be connected
in the following ways:
1. To the sink outlet spigot, securing it to the
underside of the work surface. This will
prevent waste water from the sink running
into the machine.
2. To a stand pipe provided with venthole,
minimum internal diameter 4 cm.
The waste connection must be at a height of
between 30 cm (minimum) and 100 cm
(maximum) from the bottom of the
dishwasher.
The drain hose can face either to the right or
left of the dishwasher.
Ensure the drain hose is not bent or squashed
as this could prevent or slow down the
discharge of water.
The sink plug must not be in place when the
machine is draining as this could cause the
water to syphon back into the machine.
If you use a drain hose extension it must be
no longer than 2 metres and its internal
diameter must be no smaller than the
diameter of the hose provided.
Likewise the internal diameter of the
couplings used for connections to the waste
outlet must be no smaller than the diameter
of the hose provided.
