  • Page 4 The purpose of this Service Manual is to provide service engineers who are already trained in the repair of traditional dishwashers with specific technical information relative to the new range of New Structure dishwashers known as the “EVOLUTION” range. The structural and hydraulic characteristics, as well as the basic circuitry, are common to all the appliances.

  • Page 5: Introduction

    The use of massive resources and extensive experience, combined with modern technical and contruction methods, have made it possible to develop this new range of innovative appliances which meet the demands of a market in continuous evolution. MAIN CHARACTERISTICS STRUCTURE: Modular and convertible, in three versions: Free-Standing, Fully-Built-in, Partially Buily-in (control panel visible).

  • Page 12: Structure Of Hydraulic Circuit

    DESCRIPTION OF HYDRAULIC CIRCUIT The washing system is carried out by two main sections: The BASE, designed to contain liquids The IWMS water softening system. BASE The base is not only the main load-bearing structure of the appliance and of the main functional and electrrical components, but also houses part of the hydraulic circuit.

  • Page 13: I W M S

    I W M S Integrated Water Management System The external casing in transparent plastic consists of two half-shells that are welded together. The casing contains the resins (water softening substances) as well as a number of special chambers and ducts for treatment of the water. These have the following functions: - WATER FILL CIRCUIT - WATER FILL CONTROL SYSTEM - FILL WATER TREATMENT SYSTEM...
  • Page 14 WATER FILL CIRCUIT The operating conditions for regular operation of the water fill circuit are as follows: Fill solenoid energized Volumetric control reservoir empty Reset solenoid energized Pressure switch set to “empty” (1 - 2) PATH OF WATER FILL From the solenoid valve (3), the fill water passes across the air break (5) and descends through the resin reservoir (10) and then to the volumetric distributor (11), where it is subdivided into two parts: A small quantity (1/6) of the total quantity of water is ducted into the reservoir of the volumetric control device (12).

  • Page 16: Control Of Drain

    WATER FILL CONTROL SYSTEM This system refers to the path taken by the water inside the IWMS during the fill phase, starting from the inlet connected to the fill solenoid and passing through the entire internal circuit until it reaches the tub. The fill control system consists of the following sub-systems: - VOLUMETRIC CONTROL OF WATER FILL - CONTROL OF THE LEVEL OF WATER IN THE TUB...

  • Page 17: Drain

    WATER DRAIN CIRCUIT OPERATION The motor is actioned in the drain direction in order to drain the water from the sump (17). At the same time, a vacuum is generated in the IWMS level circuit and, via the level siphon (15), empties the pressure chamber.

  • Page 18: Water Softening

    WATER SOFTENING SYSTEM SOFTENING PROCESS This water softening system utilizes resins (synthetic organic substances) in a chemical ion-exchange process. The exchange process takes place rapidly: as soon as the water comes into contact with the resins, the exchange process beings. The calcium and magnesium contained in the water are removed, while the resins provide sodium.
  • Page 19 REGENERATION CIRCUIT When the regeneration solenoid (9) is powered electrically, the water contained in the regeneration reservoir (7) descends by gravity into the salt reservoir (8) (located in the base of the appliance). Passing through the salt reservoir, the water removes a given quantity of salty water, which then rises through the resin bed (11) and passes to the volumetric reservoir (11) and then into the tub.
  • Page 20 RESIN WASHING When the fill solenoid (3) is powered electrically, plain water circulates through the resin reservoir (10), passing through the fill circuit until it reaches the bottom of the sump. In effect, the water follows the same path described in “Water Fill Circuit” (page 14). At the same time, the motor (18) is actioned in the drain direction, and drains off the water as it arrives.
  • Page 21 REGENERATION VOLUMES Four volumes of water are used for regeneration, for a total of approximately 230 CC. The procedures for regulation of regeneration and the regeneration process itself differ according to the type of dishwasher (Electromechanical, Itronic, Electronic). N.B. For Itronic and Electronic dishwashers, the procedures for regulation of the regeneration level are described in the specific Service Manuals.

  • Page 22: Condensation Of Vapour

    VAPOUR CONDENSATION CIRCUIT Inside the IWMS, a special chamber, which communicates directly with the inside of the tub, allows the appliance to dry the dishes by condensing the steam. The type of drying depends on the type of dishwasher. Three drying systems are used: “IMPULSE”...
  • Page 23 “ACTIVE DRY” DRYING Description of the system: This is a new internal drying system based on natural circulation through a duct fitted externally to the ceiling of the tub and connected to the IWMS. This integrated circuit does not draw in air from the exterior. The vapour (hot, humid air) produced during the hot rinse is ducted into the chamber in the IWMS, where it is condensed in two different circuits.
  • Page 24 “TURBO” DRYING Description of the system: This is a new internal drying system based on forced air circulation provided by a fan fitted externally to the ceiling of the tub and a duct connected to the IWMS. The system consists of an integrated circuit which does not draw air into the appliance from the exterior. The vapour (hot, humid air) produced during the hot rinse is ducted into the chamber of the IWMS where it is condensed by two separate circuits.

  • Page 25: Water Fill Safety Features

    WATER FILL SAFETY SYSTEMS These safety systems detect any possible malfunctions that might result from incorrect operation of the hydraulic circuit or leakage from any of the components. The electromechanical/hydraulic safety devices are always operative during the washing cycle and, in some cases, even when the appliance is switched off.

  • Page 26: Troubleshooting

    TROUBLESHOOTING CHECKING THE EFFICIENCY OF THE COMPONENTS In order to facilitate checking of the efficiency of the component to be tested, a special CONTROL PROCEDURE has been created. The contacts to which the tester should be applied and the correct resistance for each component are shown in the table below.
