  • Page 73 Drain Pump – Aqua Control General Characteristics 1. Wheel 2. Rotor 3. Stator The pump, which drains the water at the end of the various washing cycle phases, is centrifugal and is activated by a synchronous motor. The rotor consists of a permanent magnet and the direction of rotation can be either clockwise or anticlockwise. It can turn by approximately a quarter of a revolution without turning the wheel.
  • Page 74 Circulation Pump General Characteristics In models with Jetsystem washing, a synchronous circulation pump is fitted, which is designed to circulate water continuously, withdrawing it from the filter body and introducing it into the tub through the bellow seal. It is powered directly by the main circuit board via a triac and is fitted with a thermal cut-out.
  • Page 75 “Concentrated Wash” Wash Pump General Characteristics The models featuring the “Concentrated Wash” are fitted with a synchronous pump, whose task it is to circulate the water in the cycle, to allow the detergent to break down and disperse fully, withdrawing it from the filter body and introducing it into the tub at the heating element height.
  • Page 76 Aqua Control (where featured) General Characteristics The aqua control is a sensor positioned in contact with the bottom of the machine. It detects any water leakage from inside the washing machine and feeds the drain pump (not only during normal operation but also when the appliance is turned off with the plug inserted into the power socket).

  • Page 79 Analogue Pressure Switch General Characteristics 1. Small pipe 2. Core 3. Oscillating coil The pressure switch is connected via a pipe to the pressure chamber. When water is introduced into the tub, this creates a pressure inside the hydraulic circuit that causes the membrane to change position. This in turn modifies the position of the core inside the coil, thus changing the inductance and the frequency of the oscillating circuit.
  • Page 80 Door Safety Interlock PTO (Pull to Open) General Characteristics This appliance is not fitted with a safety device featuring the traditional fastening latch which necessitated the removal of the handle to open the appliance door.

Door safety interlock (with Door sensing switch) 2a Door safety interlock (without Door sensing switch) 13. Inverter 14. Motor X-Y-Z = Motor Windings Power supply to motor Three-phase power is fed by the inverter (13), which sends through connectors 5-6-7 the three phases to connectors 1-2-3 on the motor, where the windings (Y-X-Z) are connected.
  • Page 85 Operating Principle The alternating current permanent magnets motor is a synchronous electric motor: the speed of rotation when stationary only depends on the frequency of power supply and it is independent of the load (torque at the axis). Like all electric motors, the permanent magnets motor consists of a stator and a rotor: both these components contribute to the production of torque by iteration between the respective magnetic fields.
  • Page 86 Inverter - UIMC / EMC14 General Characteristics The EWX14 electronics use a new asynchronous motor, with 2 poles, three-phase, with high performance and low noise levels. “INVERTER” operating diagram = Phase = Neutral = “INVERTER” board = Motor = Condenser = Diodes I1÷6 = Switches...
