4 INSTRUCTIONS FOR TECHNICAL STAFF

4.1 Plumbing hookup

Water supply and drain hookup

The water pipelines and electricity supply cable lead out of the bottom right-hand corner of the appliance. Connect the water intake hose to a connector with 34 " gas threaded fitting, fitting the filter A provided (in models with aquastop, the filter and ring-nut form a single unit).

The connection to the water mains must only be made with new hoses; the use of old or worn hoses is not permitted.

Technical diagram showing a valve assembly with labeled component A and directional arrow

The dynamic water supply pressure must be between 1 and 6 bar; if it is higher, installation of a pressure reducer is necessary.

It is essential to fit a main stop tap on the water intake deliver pipeline; the tap must be accessible after installation of the appliance, so do not install it behind the dishwasher. The stated cycle duration applies to appliances supplied with hot water >50^<60^ . If the dishwasher is supplied with cold water, the cycle duration might increase depending on the intake water temperature. The dishwasher is fitted with a drain pump and can operate with drain connections on the floor or wall.

Refer to the connection diagram for the maximum permitted height of wall drains – (see TECHNICAL DATA)

Caution: make sure that the intake and drain hoses are not bent, constricted or crushed after installation.

When installing the drain hose to a siphon with valve, the maximum height of the drain outlet is reduced to 600 mm.

4.2 Electrical connection

	The dishwasher and any additional equipment 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.The total rated power is stated on the appliance's technical data plate.The electrical protection devices fitted for the dishwasher must serve this appliance only.The user must have a master switch and a differential safety breaker, with rating suitable for the appliance's characteristics, installed on the electricity supply line in accordance with the relevant regulations.These switches must be installed close to the dishwasher, be easily accessible after installation, and provide complete disconnection from the electrical mains in overvoltage class III conditions.
	Warning !!!The dishwasher is always powered up unless the master switch is turned off.
	Connect the appliance to the user's earth system. The ↓ terminal for the connection is in the bottom right-hand corner of the appliance.The earth wire (PE) is yellow-green in colour, the neutral wire (N) is blue and the live wires (L1, L2, L3) are black, grey and brown.In the event of single-phase connection (230V-1N~), the connection to the electrical mains must be made using a cable with plug compliant with the relevant regulations.
	THE POWER SUPPLY CABLE MUST BE REPLACED BY THE MANUFACTURER OR AN AUTHORISED SERVICE CENTRE TO PREVENT ALL RISKS.

Figure 1 – Appliance electrical system diagram

5 FIRST START-UP

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.

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

PESO FILTRO

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 by ordering the relative kit.

As an alternative an external dispenser can be fitted, making the electrical connection by means of an H05 RN-F 2x0.5 mm electrical cable, which can be laid along the route shown in the TECHNICAL DATA diagram and connected as shown in the wiring diagram supplied with the dishwasher.

The dispenser must operate on 230V/50 Hz with maximum power absorption of 15 W.

Connect to the detergent dispenser outside the dishwasher using the red hose mentioned above.

5.1 Rinse aid dispensing setting (on models with diaphragm pump with manual setting only)

Note: If peristaltic rinse aid pump is installed see point 6.6

RV RV RB

RB	Rinse aid dispensing regulator screw
RV	Inspection panel removal screw

RB

RB: Rinse aid dispensing regulator screw Adjustments are made using the adjuster screw AS SHOWN. The quantity dispensed is reduced by turning clockwise and increased by turning anticlockwise.

5.2 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.

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 dishwasher.

Failure to comply with this recommendation leads to forfeiture of the warranty entitlement on the appliance's water system.

The internal pipes of the detergent and rinse aid pumps should be replaced by the After-Sales Service every 12 months or 15,000 wash cycles and operation of the diaphragm can be disposed of in accordance with the relevant regulationsrinse aid pump should be checked.

7 MALFUNCTIONS SHOWN ON THE DISPLAY (FOR THE TECHNICIAN)

The dishwasher is able to identify a number of malfunctions and show them on the display.

If the problem persists after the dishwasher has been switched off and back on, proceed as described below:

Err04	Tank temperature probe malfunction		Tank temperature probe disconnected or not working.
Err05	Tank water filling malfunction		The tank does not fill within the allowed time: check water intake tap, dynamic pressure in intake system, cleaning of water intake filter, possible damage to water intake hose or cleaning of rinsing nozzles.If the problem persists during FILL:- tank pressure switch has failed (continuous empty reading: check whether tank safety pressure switch is tripped)- leak from pipe connected to air trapIf the problem occurs during work cycle- filler hose bleeder valve fouled: tank empties completely at end of a wash cycle due to siphon effect.
Err06	Water pump-out malfunction		Inspect the filters for dirt and check that the drain hose is not blocked, bent or crushed.Check that the drain pump is not blocked by dirt by removing the insert on the sump (from inside the tank).
			If it persists, check in this order:- with tank empty: constant “tank full” signal: tank pressure switch faulty or leak from connections of air trap connection pipe (water entering pipe)- with tank full: drain pump failure
Err09	Too much water in tank		With tank full:see above (water pump-out malfunction)With tank empty: constant “tank full” signal: safety pressure switch faulty or leak from connections of air trap connection pipe (water entering pipe)
Err23	Boiler does not heat up as expected		The problem might occur because water is continually entering the tank (the causes are as for Err5 – see above)If it persists, check in this order:- damaged boiler heating element- contactor failure,- boiler safety thermostat failure,- boiler temperature probe faulty or incorrectly positioned- motherboard relay failure,Important: if the boiler heating element is damaged, this might be due to operation with no water in the boiler - the pressure switch is indicating full even with the boiler empty: check and if necessary replace the boiler air trap and/or the relative pressure switch: the problem is generally preceded by “boiler overheating E28”
Err24	Boiler temperature probe malfunction		boiler temperature probe disconnected or not working

Glasses

Load glasses upside down.

Cutlery

Use the basket(s) provided. Load cutlery loose, preferably with the handle at the bottom, taking care not to injure yourself with fork prongs or knife blades.

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.

Unlo 7:58 >

Press the pump-out button ⚙️ and the display shows "UnLo" and the duration.

	Confirm by pressing ➤; light L2 turns orange.
	When pump-out is complete the appliance switches to “OFF” status.

After a total pump-out the filters should be cleaned as described above.

Never switch the dishwasher off with water in the tank; always pump out first.

TOTAL PUMP-OUT AT THE END OF THE DAY + RESIN REGENERATION

(for models with water softener)

From time to time, on models with water softener, before the total pump-out at the end of the day the user will automatically be reminded to carry out the resin regeneration cycle, required after a number of washes which depends on the hardness of the water (about 30 for average setting H03). In this case the sequence will be as follows:

	Press the pump-out button; “rEgE” and the duration appear on the display.
	Confirm by pressing; light L2 turns orange.
	When pump-out is complete the appliance switches to “OFF” status.

Topping up with regenerating salt (for models with water softener)

Salt must be added when the “no salt” light (S) appears on the display.

Top up with salt when there is no water in the tank to prevent washing water from getting into the water softener device.

Caution: use only salt of the specific type, do not use cooking salt.

The salt tank has a capacity of about 1 kg of coarse-grained salt.

The salt tank is in the bottom of the appliance's tank. After removing the basket, undo the cap and pour the salt in using the funnel supplied. Remove any salt residues around the opening before screwing the cap back on.

11 MAINTENANCE AND CLEANING

Although no particular scheduled maintenance is required, users are advised to have the dishwasher checked by a specialist technician twice a year.

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.

11.1 Daily cleaning

The dishwasher has IPX4 protection, but the use of direct water jets for cleaning is forbidden.

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”).

	Press the Ⓟ button, and hold it down, until “P0” and the duration of 1’ appear on the display.
	Confirm by pressing ➤; light L2 turns orange.
	At the end of the pump-out the word “End” flashes on the display. The display returns to showing “P1”. Clean the filter; the dishwasher automatically fills the tank when the door is closed.

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 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.

IMPORTANT:The dishwasher automatically performs program "P0" at the start of the day if water has been left in the tank and has dropped below the temperature of 40°C

11.2 Routine inspection of the spray arms

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.

TOP SPRAY ARMS stainless steel BOTTOM SPRAY ARMS stainless steel 1 2 3

Clean the outside of the appliance with a damp cloth and neutral soap, rinsing and drying thoroughly.

11.3 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 door 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).

12 TROUBLESHOOTING

If the system fails to pump out because the drain pump is fouled (as a result of incorrect filter positioning), proceed as follows:

Bale out the dishwasher with a basin and disconnect it from the electrical mains.

Unscrew the screw A, release the tang B and lift it.

Check that the impeller of the drain pump underneath the cover turns freely, and is free from dirt, limescale residues, or pieces of glass. Never use tools, screwdrivers, scissors, etc.
