  • Page 12: Function Description

    -> Function Description Water Circuit Process of water inlet (indicated by magenta route) In this process, regeneration water route is cut off, main water route is open. The water in the main water route is softened when pass through the softener, and then enter in the tub. During this phase, some of inlet water will be stored in the air breaker to be regenerating water.

    Inlet Valve -> Theory of parts Access inlet valve 1. Disconnect the power. 2. Remove the water inlet hose. (Note : Be careful of remaining water droplets.) 3. Remove the cover of the bottom board. 4. Disconnect the 2 terminal lugs from the inlet valve. 5.
  • Page 18 Drain Pump -> Theory of parts Location of Drain Pump The work principle Drain pump integrated into sump Bottom view Working principle Drain pump consists of an electrical motor, impeller, inlet and outlet. Drain pump is a kind of pump driven by permanent magnet synchronous motor. The rotor is made with permanent magnet material, the running inertia of rotor is very small, the stator consist of silicon steel stack and coil.

    Washing Pump -> Theory of parts Spray pump The nominal working point of the pump is at 45 l/min at 310 mbar (total pressure difference outlet – inlet). At that point the optimum total efficiency is located. Characteristic Units Value Working points: See 2.1 at nominal voltage 230V, 50Hz and max.

  • Page 23: Pressure Switch

    Pressure Switch -> Theory of parts Working principle The pressure switch consists of a moving diaphragm and disc which activates a change over contact. The contact can be calibrated to trip and reset at the desired pressure levels. The main application is to control the level of water in the appliance and may also provide flood protection.

Access NTC 1. Remove bottom board. 2. Remove two screws securing the NTC to sump(shown in above picture). 3.
  • Page 25 -> Theory of parts To inspect NTC 1. Open the PCB box and take out the PCB; 2. With the door closed,unplug the RE connector (shown in below picture), then use the multi-meter Ω shelf to test resistance between two blue wires(RE and GND) , the normal resistance is shown in below table.
  • Page 26 Flowmeter -> Theory of parts Location of Flowmeter Working principle Flowmeter is integrated into Air Breaker. Function of Flowmeter is measure how much water has entered the appliance. It consists of an impeller, tongue tube and terminal, etc. When water passes through the flowmeter, moving water rotates the magnetic impeller, the tongue tube can sense the impeller’s magnetism and sends electronic pulses.
  • Page 27 Flowmeter -> Theory of parts Access Flowmeter 1. Remove the baseboard, top panel and left side panel. 2. Remove the plastic nut inside tub, which secures the air breaker to tub. (The flowmeter is integrated into air breaker, replace air breaker if flowmeter has failed. ) 3.
