5 PREPARING 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: corner guards, top of packaging.
Wooden and cardboard components can be disposed of in accordance with the local regulations.
All operations described in this section must be carried out and/or checked by the qualified
staff who install and commission the dishwasher.
5.1 Positioning and installation
Place the dishwasher in the chosen point and remove the protective film. Level the dishwasher (with the
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 constitute a
hazard.
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.
12
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 ensure optimal 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.
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 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.
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.
13
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 of the
drain hose must be fixed to the drain connection using the hose clamps provided.
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.
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 rated electrical 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 undergo a functional test before the
dishwasher is put into operation. If the dishwasher is connected to the electrical mains by means of a 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 after the
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.
Do not connect the dishwasher to the electrical mains by means of adapters or extensions,
since they may cause dangerous overheating.
Connect the appliance to the earth system. The earth connection terminal is low down on
the back of the appliance and is marked with the symbol.
The dishwasher is always powered up unless the master switch is turned off or, on
appliances with power plug, the plug is disconnected.
14
6 FIRST START-UP
6.1 First start-up
The electrical protection system must undergo a functional test before the appliance is put into operation.
The appliance must be installed and/or inspected 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.
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.
Replacement of the internal tube of the detergent and rinse aid peristaltic pumps is recommended every
12 months or 15.000 wash cycles, by the After-Sales Service.
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 to ensure 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.

and rinse aid consumption.
19
Thermostop
Set as “on” = minimum rinsing temperature as set, (see
boiler temperature above) regardless of intake water
temperature; the cycle duration may be a few seconds
longer than the nominal length.
Set as “off” = the minimum rinsing temperature might be a
few degrees lower than the setting if hot intake water is not
used.
If the thermostop device is set “off” the rinsing °t are no longer monitored and the user is
responsible for ensuring that the minimum correct °t are maintained for the tank and boiler. It is
particularly important to check the intake water temperature.
Also refer to the insufficient washing/drying /foam in tank point of the “troubleshooting” section :
restore °t Stop ON and/or connect the appliance to a hot water supply.
High speed (FST) or economy (ECO) filling (FILL)
Fast start (FST): starts the dishwasher in less than the
standard time; leads to higher water consumption for the
first cycle start.
Eco start (ECO): starts the dishwasher in standard time, with
no added water consumption.
On: enabled – OFF: disabled.
Cycles performed counter

This is the final phase of the program which eliminates the
steam created during rinsing, preventing it from escaping
into the work environment.
If the machine is opened while this operation is being carried
out (not recommended), the steam heat recovery phase
stops and is not resumed when the machine is closed. The
current cycle is therefore stopped permanently.
Duration: customisable from 40 to 120 seconds.

7.3 Starting the peristaltic pumps – rapid filling of detergent and rinse aid delivery
circuit.
Perform after the parameter modification procedure explained in the previous point
With the dishwasher powered up and the tank full, press the
on/off button for a few seconds; when ------ appears on
the display, release the button and press it again quickly
within 0.5 seconds.
The peristaltic pumps continue to operate until the same
button is pressed again. The rinse aid and detergent symbol
lights flash alternately as long as the pumps are on; bear in
mind that the rinse aid peristaltic pump fills the circuit in
about 7 minutes, while for the detergent it only takes 2
minutes. So draw only rinse aid from the jerry cans (1 for the
rinse aid and the other for the detergent) for the first 5
minutes and then also take in detergent for the last 2.
On some models, the message “door” (PCB self-diagnostics on dishwasher closure) may
appear during the setup procedure. To reset the message, open the dishwasher door and
close it again. If the message persists, contact the after-sales service.

water filter, any damage of the water charging hose, or check the
following in this order:
- faulty boiler pressure switch (it always detects “empty”),
- leakage or unbinding of the tube (water runs inside the tube)
- menu service wrong setting “rP”
- faulty boiler pressure switch (it always detects “full”)
- leakage or unbinding of the tube (water runs inside the tube)
- rinsing pump malfunction (if present)
Faulty boiler pressure switch (it always detects “full”). If this
occurs in models without rinsing pump, the boiler pressure
switch is wrongly detected: check settings in the service menu on
entry “rP”
“rp” = on for models with rinsing pump
“rp” = of for models without rinsing pump

9.1 Before washing
Use only detergents and rinse aids for industrial dishwashers. Do not use detergents intended
for hand washing.
We recommend the use of Smeg products, specially developed for this dishwasher.
When topping up the tanks, take care not to swap the products; this might damage the
dishwasher and cause malfunctions.
Do not mix different detergents; this would damage the dispenser device. Failure to comply with this
recommendation leads to forfeiture of the warranty entitlement on the appliance’s water system.
Industrial dishwasher detergents may cause serious irritation. Comply carefully with the instructions
provided by the detergent producer on the pack.
Check:
Switch on the
master switch
(user): the
decimal points
of both digits

10 CHOSING THE PROGRAM
When you scroll through the available programs, the program number (P1, P2, .... etc.) and its duration are
shown first, alternating with the wash and rinse temperatures.
PROGRAM TYPE OF DIRT DURATION (*)
DISHES Short P1 Lightly soiled plates 1 min
DISHES Long P2 Heavily soiled plates 2 min
TRAYS P3 To wash pans and trays 3 min
POTS P4 Pots and pans 4 min 10s
CUTLERY P5 Intensive programm with 70°C washing 7 min 10s
USER PR P6 Customisable (see "set-up information") 1- 10 min
(*) The cycle duration stated above is guaranteed if the water intake temperature is as stated and
recommended in the "TECHNICAL DATA" table, and in all cases refers to the first cycle performed. For
repeated cycles, operating conditions may vary from installation to installation. If the dishwasher is
supplied with cold water, the cycle duration might increase depending on the intake water temperature
and the "thermostop" setting.
Power blackouts.
If the dishwasher is open when power is restored, the display will read “°t” and the heating
element will remain off, to prevent the risk of burns to the user.
Close the dishwasher to resume heating the water in the tank.
ENABLING/DISABLING THE PROGRAM NAME ON THE DISPLAY
By default, the display shows the program number P1, P2, P3, and its duration, alternating with the wash
and rinse temperatures. It is also possible to display the name of the program. In this case, the name of the
program will be displayed first and the progressive program number and the duration will be displayed on
the following screen e.g. Glass >>> P1 1:10.
The procedure must be carried out with the machine switched off but powered.
Press and hold down the start / pause button.
When the vertical lines ||||| appear on the display, release the start / pause button and then press it
again immediately.
The procedure is complete; there is no audible or visual confirmation.
It is possible to check if the procedure has been carried out correctly when the machine is switched on
again.

11 BASKETS PROVIDED
The shape and material of the baskets provided with the dishwasher depend on the purchased model.
Extra baskets can be purchased through the After-Sale Service. The following images are indicative.
Glasses: Place the glasses downwards.
Cutlery
Use the dedicated basket.
Place the cutlery
randomly, preferably with
the handle downwards,
using caution to avoid
injures due to prongs of
forks and blades of knives.
30
12 MAINTENANCE AN CLEANING
We recommend regular servicing by a SMEG authorised service centre at least once a year, to guarantee
optimal performance at all times.
Consumables (e.g. peristaltic pump hoses) and/or parts subject to wear and tear must be replaced with
genuine SMEG parts.
N.B.: the manufacturer accepts no liability for wilful damage or damage deriving from carelessness,
neglect, failure to comply with instructions, regulations and standards or incorrect connections, which lead
to forfeiture of warranty cover.
The dishwasher has IPX4 protection, but the use of direct water jets for cleaning is forbidden.
Remove the filters (simply lift them out as shown here), taking care that
no large residues fall into the sump underneath. Clean them to remove
residues and rinse with plenty of water, then put them correctly back in
place; do not use sharp or pointed tools.
Clean away any limescale deposits to prevent excessive build-ups;
If possible, leave the hood or door ajar when not in use;
Clean surfaces thoroughly and often with a damp cloth; use neutral,
non-abrasive detergents which do not use chlorine compounds, which
corrode and damage stainless steel.
Do not use the products mentioned above even when cleaning the floor underneath or in the vicinity of the
dishwasher, to ensure that fumes or drops cannot damage the steel surfaces.
31
12.1 Cleaning the filter during the day
In case of particularly heavy-duty working conditions, the filter should be cleaned every 30-40 cycles, keeping
the machine in operating conditions; to do this, carry out the “partial tank pump-out” routine (program
“P0”)) (TANK UNL).
Press the button, and hold it down, until “TANK
UNL” and the duration of 2’ appear on the display.
Confirm by pressing ; light L2 turns blue.
At the end of the pump-out the word “END” flashes on
the display. The display returns to showing “P1”. Clean
the filter in accordance with the instructions.
After cleaning the filter:
for "undercounter" models, press to start filling (FILL).
for hood-type models, filling (FILL) starts automatically when the hood is closed.
12.2 Total pump-out at the end of the day
The dishwasher is able to perform an automatic cleaning cycle at the end of the day.
Press the button to start draining the appliance
completely. "UNL" and the duration will appear on the
display.
Never switch the dishwasher off with water in the tank; always pump out first.
The indicator L2 becomes blue.
When finished, the dishwasher switches off.
32
12.3 Topping up with regenerating salt (for models with softener)
Warning: use specific salt only, do not use cooking sea salt. Salt must be
supplied when the led under the symbol indicated in the left side picture
lights up. The salt container has a capacity of about 1 kg of granulated salt.
Correct procedure to refill the regenerating salt:
- start a tank pump-out,
- refill the regenerating salt,
- fill the tank (FILL)
- restart the tank pump-out
- remove any salt residues from the bottom of the tank, as it may cause
corrosion/rust.
This procedure prevents the washing water to enter the salt container
(possible damage to the decalcifier) and that possible residues of salt are
left in the tank (risk of corrosion/rust).
12.4 Routine inspection of the spray arm (once a week )
Remove the washing and rinsing (top and bottom) spray arms by unscrewing the central screw; remove the
rinsing spray arms 3 and remove the screws 2 as shown. Do not unscrew the nozzles. Clean the holes and
nozzles under a jet of clean running water; do not use tools which might cause damage. Reassemble the
spray arms with care.
Clean the outside of the appliance with a damp cloth and neutral soap, rinsing and drying thoroughly.
12.5 Lengthy periods out of use
If the dishwasher is to be out of use for a fairly long period of time, the detergent and rinse aid dispenser
devices must be emptied to prevent crystallisation and damage to the pumps: remove the intake hoses
from the detergent and rinse aid containers and place them in a container of clean water, then perform a
few wash cycles followed by a complete pump-out. Finally, turn off the master switch, close the water
intake valve and leave the hood ajar until the interior is completely dry. The detergent and rinse aid intake
hoses must be put back into the containers when the dishwasher is returned to service, taking care not to
swap them over (red hose = detergent, blue hose = rinse aid).
