T o prevent water hammer, we recommend the fitment
of a Noise Reduction Valve in the water supply line.
These valves also act as a pressure reducing valve with
the added benefits of:
– Reducing the chance of a burst hose
– R educing the water noise whilst the dishwasher is filling
with water
P ressure reducing valves, water temperature tempering
valves and noise reduction valves are available from major
plumbing suppliers. DO NOT connect your dishwasher to
the outlet of an unpressurised displacement instantaneous
water heater, (for example a push through type sink heater)
as damage to the heater may result.
• Water inlet hose with safety valve
S ome models are supplied with an inlet hose that has
a double-walled water hose and a safety valve on the
threaded hose fitting next to the tap. Therefore the water
inlet hose is only under pressure while the dishwasher
is filling. If the water inlet hose starts to leak during this
operation, the safety valve, controlled by the dishwasher,
cuts off the water supply to prevent flooding.
Please take care when installing the safety inlet hose:
• T he distance between the bottom edge of the safety valve
and the floor on which the dishwasher is standing must be
at least 300mm.
• T he electrical cable for the safety valve is in the double-
walled water inlet hose. Do not immerse the water inlet
hose or the safety valve in water.
• Do not attempt to shorten the inlet hose.
• I f the water inlet hose or the safety valve is damaged,
immediately turn off the power and remove the mains plug.
• A water inlet hose fitted with a safety valve must only be
replaced by a qualified Service Engineer.
• I f your dishwasher is fitted with a "safety hose" you will
need an opening of at least 45mm x 90mm in your
cupboards in order to feed the hose through it.
• E nsure that hoses are not crushed or kinked under or
behind the dishwasher.
• A fter connecting hose to the tap, turn the tap on and
check to ensure that there are no leaks.

ConneCTing The Drain hose
• The drain hose must be free of kinks and obstructions.
• T he highest point of the hose should not be more than
1 metre from the floor and should have a continuous fall.
• T he drain hose may be lengthened using additional lengths
and connectors, which can be purchased from Electrolux
Spare Parts. The extension length must not exceed 2 metres.
Remove internal membrane from drain spigot
When connecting the drain hose to an under sink trap spigot,
the entire plastic membrane must be removed.
Failure to remove all the membrane will result in food particles
building up over time eventually blocking the dishwasher drain
hose spigot.
eleCTriCal ConneCTion
• Safety standards require the appliance to be earthed.
• P rior to using the appliance for the first time, ensure that the
rated voltage and type of supply on the rating plate match
that of the supply where the appliance is to be installed.
The fuse rating is also to be found on the rating plate.
• A lways plug the mains plug into a correctly installed
approved socket.
• M ulti-way plugs, connectors and extension cables must not be
used. This could constitute a fire hazard through overheating.
• I f necessary, have the domestic wiring system socket
replaced. If the electrical supply cord has to be replaced,
contact your local Customer Care centre.
• T he plug must be accessible after the appliance has
been installed.
• N ever unplug the appliance by pulling on the cable.
Always pull the plug.
• E nsure that the dishwasher has been tested using the rinse
& hold or quick 30 cycle and that the dishwasher fills with
water, washes and drains with no leaks.
The manufacturer accepts no liability for failure to observe the
above safety precautions.
