Page 14: Washing System
DIVA Service Manual - EDW 1001 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. -
Page 15: Hydraulic Circuit
DIVA Service Manual - EDW 1001 Hydraulic circuit 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, the water is ducted through a channel into the regeneration chamber (7). -

Page 17: Dynamic Fill
DIVA Service Manual - EDW 1001 5.1.3 Dynamic fill The motor is switched on at 2300 rpm, and water is introduced for 10 seconds (fixed time). This condition makes it possible to start filling the hydraulic circuit. This is followed by: 5.1.4 Pause The motor is switched off and the fill solenoid is disactivated for 5 seconds in order to allow the water to... -
Page 18: Supplementary Fill
DIVA Service Manual - EDW 1001 5.1.7 Supplementary fill On completion of the water fill phase, and before proceeding to the subsequent washing phase, the system performs a fixed-duration percentage water fill which depends on the speed of the motor for the subsequent washing phase (as specified in the cycles table). -
Page 19: Control Of Stability During The Washing Phase
DIVA Service Manual - EDW 1001 Control of stability during the washing phase When the fill phase is complete, the appliance passes to the washing phase. In the washing phase - with cold or heated water - the status of the pressure switch is monitored constantly in order to ensure that the hydraulic system operates efficiently. -
Page 20: Anti-Overflow Safety System
DIVA Service Manual - EDW 1001 Anti-overflow safety system In all dishwashers in the new range, the anti-overflow safety system is constantly monitored by the safety pressure switch (which acts as a pressure sensor) in order to prevent water from overflowing due to an excessively high level. -
Page 21: Regeneration System
DIVA Service Manual - EDW 1001 Regeneration system In this series of dishwashers, regeneration of the softening system, whose duration is approximately 3 minutes, takes place towards the end of the washing cycle, during the drying phase. Regeneration of the softening system is governed by the electronic control system at “ad hoc”... -
Page 22: Selecting The Regeneration Level
DIVA Service Manual - EDW 1001 5.6.2 Selecting the regeneration level Press and hold down programme buttons [S1] and [S2] simultaneously. Press the “ON/OFF” button [S0]. The corresponding LEDs [LD1] and [LD2] begin to flash. Press button [S1]. The LED [LD2] switches off, while LED [LD1] stops flashing and remains lit for about 5 seconds. -
Page 23: Drying Circuit
DIVA Service Manual - EDW 1001 Drying circuit In these dishwashers, the dishes are dried by means of a steam condensation process. Depending on the type of appliance, one of two drying systems is used: - “ACTIVE - DRY” drying - “TURBO - DRY”... -
Page 24: Turbo Dry" Drying System
DIVA Service Manual - EDW 1001 “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. This drying system is based on the forced circulation of the hot air produced during the hot rinse, where the steam (hot, humid air) is drawn in by the fan located inside the upper duct and then ducted towards the condenser in the fill tank, from where it returns to the tub via the steam venting ring. -
Page 25: Safety/Control Systems And Alarms
DIVA Service Manual - EDW 1001 Safety/control systems and alarms The dishwashers in this new range feature a series of safety systems which protect the appliance in the event of malfunctions, whether it is switched on or off. In the event of a situation that might compromise the correct operation of the appliance, the electronic control system causes a specific safety system to intervene. -

DIVA Service Manual - EDW 1001 7.4.3 Intervention of anti-flooding system - Alarm [A L 4] - LEDs [LD9] + [LD10] This control system is operative during the washing phases only, and not in the water fill phases, which in this case are associated with the safety device. If water is present in the bottom, a floating mechanical sensor positioned on the bottom of the appliance trips a microswitch which is connected in series to the fill solenoid valve, thus disconnecting the solenoid valve. -
