5PREPARING THE APPLIANCE FOR USE
Convey the dishwasher to the installation site, remove the packaging and check the appliance and
components for damage; any damage found must be reported to the transporter in writing. The packaging
components (plastic bags, expanded polystyrene, nails, etc.) must not be left within reach of children and
pets since they are potentially dangerous. All packaging materials used are environment-friendly. They can
be kept without constituting any hazard, or may be disposed of at a specialist waste disposal centre. The
plastic components suitable for recycling are marked as follows:
PE -polyethylene: external packaging film, bag containing the instructions, protective bags.
PP - polypropylene: straps used to close the packaging.
PS -expanded polystyrene: cornerguards, top of packaging.
Wooden and cardboard components can be disposed of in accordance with the local regulations.
5.1 Positioning and installation
Place the dishwasher in the chosen point and remove the protective film. Level the dishwasher (withthe
aid of a spirit level) on its four feet, adjusting them to ensure that it is stable. If the dishwasher is installed
above the ground, make sure that the stand and dishwasher are secured properly and do not constitutea
hazard.
All operations described in this section must be carried out and/or checked by the qualified
staff who install and commission the dishwasher.
The systems and premises in which the dishwasher is installed must comply with the relevant
regulations.
If the dishwasher is installed next to another appliance, also check the recommendations
provided by the manufacturer of the adjacent appliance.
Installations other than those described must first be approved by the manufacturer.
Use only professional furnishings and units in the vicinity of the dishwasher. Any other types
of furnishing may be damaged.

11
5.2 Connection to the water supply
Check that the intake water pressure, flow rate and temperature are as stated in the
dishwasher's technical characteristics. If the dynamic pressure exceeds the limit stated
in the technical characteristics, a pressure reducer must be installed. If the pressure is
lower, it might be necessary to fit a special pump to ensureoptimal performance.
Connect the water intake hose to a connector with ¾” gas threaded fitting, inserting
the filter "A" provided. The tap must be easily accessible after installation of the
appliance.
5.3 Drain connection
The dishwasher is fitted with a drain pump and can operate with drain connections on the floor or wall.
Before connecting the hose, check that the diameter and height of the wall drain connection are as stated
in the dishwasher's technical characteristics. When connecting the dishwasher's drain hose, take care to
avoid kinks, sharp bends or crushing. Since the drain water temperature can be very high, the end ofthe
drain hose must be fixed to the drain connection using the hose clamps provided.
Only use new hoses for connection to the water supply. Old hoses or hoses salvaged from
previous installations must not be used.
If the water supply system has been unused for a long time or if work has been done on it,
before connecting the appliance's intake hose run the water to flush the air and dirt from the
pipes.
FOR MODELS WITH A WATER SOFTENER
An “approved” double check valve or some other noless effective device providing backflow
prevention protection to at least fluid category two shall be fitted at the point of connection
between the water supply and the fitting or appliance.
FOR MODELS WITHOUT A WATER SOFTENER
An “approved” single check valve or some other no less effective device providing backflow
prevention protection to at least fluid category two shall be fitted at the point of connection
between the water supply and the fitting or appliance.
The drain connection must be made in accordance with the relevant national regulations.
Substandard connections may cause flowback and in some cases pollution.
No extensions must be added to the drain hose supplied with the appliance. Any extensions
might cause drainage problems.

12
5.4 Connection to the electricity supply
The dishwasher must be connected to the electrical system by authorised, skilled staff, in accordance with
the relevant regulations. Also comply with the technical instructions for the connection provided with the
appliance. The dishwasher's ratedelectrical characteristics are provided on its technical data plate. A
circuit breaker with contact gap rated for category II overvoltage and an overcurrent protection device
(magnetothermal switch or fuses) must be installed in an easily accessible position on the dishwasher's
power supply line. These devices must only serve the dishwasher and must be suitable for its rated
electrical characteristics. The electrical protection devices must undergoa functional test beforethe
dishwasher is put into operation. If the dishwasher is connected to the electrical mains by means ofa plug,
it must be of the same type as the power socket, suitable for the appliance's rated electrical characteristics
and compliant with the relevant national regulations. The power plug must be easily accessible afterthe
appliance has been installed.
Electrical safety is only ensured if the dishwasher is connected to an earth conductor
compliant with the relevant electrical regulations. If in doubt, have the system inspected by a
qualified electrician.
Donot connect the dishwasher to theelectrical mains by means ofadapters or extensions,
since they may cause dangerous overheating.
Connect the appliance to the equipotential bonding system. The equipotential terminal is
low down on the back of the appliance and is marked with the symbol.
Additional recommendation: class B all-current sensitive residual-current circuit breaker with
a tripping current of 30 mA
The dishwasher is always poweredup unless the master switch is turnedoff or, on
appliances with power plug, the plug is disconnected.

13
6FIRST START-UP
6.1 First start-up
The electrical protection system must undergoa functional test before theappliance is put into operation.
The appliance must be installed and/orinspected by qualified staff, who will start it up for the first time
and provide the relevant operating instructions.
6.2 Preparing for use ( Important )
The rinse aid dispenser is fitted on all models, the detergent dispenser only on some.
If both dispensers are present put the external detergent and rinse aid containers in place and insert the
respective intake hoses on the rear of the appliance into them. Red hose: detergent, blue hose: rinse aid.
Before inserting the hoses into the containers, fit the weights (needed to ensure that
they always draw in liquid from the bottoms of the containers) and the filters onto their
ends as shown. If the detergent dispenser is not factory-fitted, it can be retrofitted after
ordering the relative kit.
6.3 Using the water softener (on models with this feature only)
The quantity of lime in the water (which indicates its hardness) causes whitish marks
on dry dishes and dishes also tend to lose their shine over time. The dishwasher is
equipped with an automatic water softener which removes the substances that
cause hardness from the water with the aid of regenerating salt.
The first time the dishwasher is used, a litre of water must be poured into the tank
with the salt. Whenever the tank is filled, always take care toensure that the cap is
firmly closed. The mixture of water and detergent must not get into the salt tank, as
this would impair operation of the regeneration system. In this case warranty cover
will be forfeited.
IMPORTANT:
Whenever the type of detergent or rinse aid is changed, it is ABSOLUTELY ESSENTIAL to flush out the
peristaltic pumps by placing the external intake pipes in water for a few cycles. Always use only products
specifically recommended for use in a professional dishwasher. Failure to comply with this
recommendation leads to forfeiture of the warranty entitlement on the appliance’s water system.

persists after the dishwasher has been switched off and back on, proceed as described below:
Er 04 Tank temperature probe
malfunction Tank temperature probe disconnected or faulty.
Er 05 Tank water filling malfunction
- The tank wasn’t filled in the expected time: check the water
supply tap, the dynamic supply pressure, cleanliness of the inlet
water filter, cleanliness of the rinse nozzles, any damage of the
water charging hose. If the problem persists during filling:
- Work level tank pressure switch damaged (it always detects
“empty”: check if the tank safety pressure switch starts
operating).
- Leakage from the tube connected to the air trap; if the problem
is not solved, it occurs during the work program.
- vent valve of the drain pipe obstructed with dirt: with
siphonage, the tank gets completely empty at the end of a
washing program.
Er 06 Water pump-out malfunction
Check:
- filter cleanliness; obstructions, bending and narrowing of the
drain pipe.
-possible obstructions ofthe drain pump (blocked with aforeign
body).
Er 23 Boiler does not heat up as
expected.
The problem might occur because water is continually entering
the tank (the causes are as for “Er 05” – see above) If the boiler
heating elementis damaged,this might bedueto operationwith
no water in the boiler - the pressure switch is indicating full even
with the boiler empty: - damaged boiler heating element –
contactor failure - open on boiler safety thermostat side. - boiler
temperature probe faulty or incorrectly positioned -
