Page 12: Structural Characteristics
2 STRUCTURAL CHARACTERISTICS The appliance consists of four main assemblies: - BASE - DOOR - TUB - HYDRAULIC SYSTEM These four assemblies are enclosed in a cabinet designed with the following removable parts: - Front panel (secured by two screws) - Two side panels (secured by six screws) - A work-top (free-standing versions only) secured to the structure by two screws at the rear. - Page 13 2.2.4 DOOR HINGE In galvanized pressed steel, with a series of mechanisms (springs, levers, spindles) which form the system of movement for aperture/closure of the door. - Secured externally to the two lateral uprights (D) by pressure-fitted couplings and screws with metric thread. - Hinges with different functional characteristics and settings are used, depending on the styling of the appliance.
-
Page 14: Tub
2.3 TUB The tub assembly consists essentially of a stainless steel tub and a series of sub-assemblies which form the load-bearing structure of the dishwasher. Two basic tubs have been designed, to suit the type of drying to be performed by the dishwasher. - The difference between the two lies in the presence or absence of a hole (*) in the rear section of the tub ceiling, to which the drying duct can be fitted. -
Page 15: Hydraulic System
2.4 HYDRAULIC SYSTEM The hydraulic system is common to all versions of the dishwasher, since its specific water softening function consists of a number of specific components. The only difference is the featuring or not of the water softening system. 2.4.1 HYDRAULIC PATH WATER INTAKE HOSE - Water intake from the mains supply circuit. -

Page 17: Water Fill Tank
3.1 WATER FILL TANK The water fill tank is a container in transparent moulded plastic consisting of two sections that are welded together. Inside the tank, special chambers and ducts define the path taken by the water during the fill phase. The fill tank is positioned in the left-hand section of the appliance, and is screwed into position from inside the tub using a fixing ring. -
Page 18: Sump Assembly
3.3 SUMP ASSEMBLY The sump is a monobloc container in plastic material, and consists of three thermowelded sections: PRESSURE, WASHING and DRAIN. The sump is located on the bottom of the tub, with a perimetral sealing ring, and is secured from the inside by four screws. PRESSURE section (A) An integral part of the WASHING section, in which a double pressure chamber controls the level of the water. -
Page 19: Electrical Components
4 ELECTRICAL COMPONENTS 4.1 TERMINAL BLOCK The terminal block consists of a junction box to which the power cable is connected; the wiring is then routed to the appliance's ON/OFF switch. The terminal block is pressure-fitted into a housing inside the base. -
Page 20: Washing Pump
4.5 WASHING PUMP Single-phase asynchronous two-pole motor with a single direction of rotation. Counter-clockwise rotation (seen from impeller side). The hydraulic group (pump scroll casing, sealing rings and impeller) is clamped to the motor shield, with an internal sealing ring. Secured to the base of the appliance by two supports in vibration-damping rubber. -
Page 21: Tube-Encased Heating Element
4.9 TUBE-ENCASED HEATING ELEMENT The heating element, which is encased inside a tube, is used to heat the washing water. The heating element is not activated during the drying phase. Inserted into the delivery side of the washing pump and coupled with the duct which directs water to the upper spray arm. -
Page 22: Integrated Dispenser
4.13 INTEGRATED DISPENSER The integrated dispenser consists of a plastic container comprising two separate sections which contain Detergent (A) and Rinse-aid (B). Fitted to the interior of the inner door and secured by two screws. The dispenser uses a single electrical coil connected to a mechanical system and which performs both functions. -
Page 23: Washing System
WASHING SYSTEM The washing system is of the traditional type in which the mechanical washing action is provided by the rotation of the washing pump. The pump ducts the water into the hydraulic circuit, thus actioning both spray arms simultaneously. In order to obtain the washing result, the system also requires features such as heating of the water, change of the water, introduction of detergent and rinse-aid etc.. -
Page 24: Hydraulic Circuit
6 HYDRAULIC CIRCUIT 6.1 PATH OF WATER INTAKE - "SHORT TANK" From the solenoid valve (2/3), the water is ducted into the fill tank and across the air break (5) into the regeneration chamber (7) until the chamber is full. Once the chamber is full to overflowing, and the softener system is featured, the water is divided into two parts through two separate channels. -
Page 25: Path Of Water Intake - "Long Tank
6.2 PATH OF WATER INTAKE - "LONG TANK" From the solenoid valve (2/3), the water is ducted into the fill tank and across the air break (5) into the steam condenser (6) until the condenser is full. When the condenser is full to overflowing, and the softener system is featured, the water is ducted through a channel into the regeneration chamber (7). -
Page 26: Water Fill System - Functional Description
6.3 WATER FILL SYSTEM - FUNCTIONAL DESCRIPTION In all versions of the dishwasher (electromechanical and electronic), the water fill system is constantly controlled by the level pressure switch, which acts as a pressure sensor. 6.3.1 DEFINITION OF WATER LEVEL The pressure switch is connected hydraulically to the sump, inside which an air trap (pressure chamber) is connected via a small tube in order to determine the level of water in the appliance. -
Page 27: Water Softening System
6.5 WATER SOFTENING SYSTEM 6.5.1 SOFTENING PROCESS If featured, this softening system is based on the use of resins (organic synthesis substances) and a chemical process of ion exchange. This exchange takes place rapidly, i.e. as soon as the water comes into contact with the resins. The calcium and magnesium salts contained in the water are removed, while their sodium base is created. - Page 28 6.5.3 WASHING THE RESINS On completion of the regeneration process, it is necessary to clean the softening circuit by washing the resins in order to remove any residual impurities. The water in the resin reservoir (9), which contains alkaline salts (calcium and magnesium) and sodium chloride, must be cleaned before the subsequent fill phase in order to ensure that it does not come into contact with the dishes or the internal parts of the appliance, since it is corrosive.
-
Page 29: Definition Of The Regeneration System
6.6 DEFINITION OF THE REGENERATION SYSTEM In all versions of the dishwasher (electromechanical and electronic), regeneration of the softener (duration 3 minutes approx.) is performed towards the end of the cycle, during the drying phase. 6.6.1 “BLENDING” FUNCTION This function is performed inside the fill tank during the water fill phase which, depending on the position of the selector, automatically blends the softened water with the unsoftened water present in the appliance. -
Page 30: Definition Of The Drying Circuit
DEFINITION OF THE DRYING CIRCUIT In these dishwashers, the dishes are dried by means of a steam condensation process. Depending on the type of appliance, one of three drying systems is used: - "NORMAL - DRY" drying - "ACTIVE - DRY" drying - "TURBO - DRY"... -
Page 31: Active - Dry" Drying
7.2 "ACTIVE - DRY" DRYING DEFINITION OF THE SYSTEM The "Active Dry" system is characterized by an integrated closed circuit in which the hot air is circulated in a bi-directional convection movement onto a cold wall; no air is drawn in from the exterior. This drying system is based on the natural circulation of the hot air produced during the hot rinse, where the steam (hot, humid air) circulates inside the condenser of the fill tank through two connector ducts, thus generating the process of condensation. -
Page 32: Turbo - Dry" Drying System
7.3 "TURBO - DRY" DRYING SYSTEM The "Turbo Dry" system is characterized by an integrated closed circuit in which the hot air is circulated in a mono-directional convection movement onto a cold wall; no air is drawn in from the exterior.
