COMPONENTS AND MEASUREMENT VALUES WASHER MOTOR W600/W620, 60 Hz Part no.: 80 617 72 Resistances: Pins 6-7 69.4 Ω Pins 4-5 5.4 Ω* Pins 2-3 1.7 Ω Pins 1-3 0.7 Ω * 1.7 Ω measured diagonally across the collector W640/W660, 60 Hz Part no.: 80 617 74 Resistances: Pins 1-2 68.7 Ω Pins 3-4 1.65 Ω Pins 5-6 1.52 Ω* Pins 5-7 0.58 Ω * 1.9 Ω measured diagonally across the collector. The motor is a universal motor controlled by an external motor control board. The rotation speed is stepless and controlled by a tachogenerator on the motor. The maximum speed is 1600 rpm. MOTOR CONTROL BOARD (W640/W660) Part no.: 80 613 99 The motor control board is via an external unit located in the base and connected to the program control unit (PCU), see the electrical schematic diagram. HEATING ELEMENT, 2000 W Part no.: Resistance: 80 617 06 28.4 W THERMISTOR Part no.: 80 616 63 Resistance: 40-60 kW Room temperature: 68°-86° F (20-30° C) The thermistor for temperature measurement is located between the motor cradle and the holder. The thermistor measures and controls the water temperature. The heating element is switched out if the thermistor short-circuits or is disconnected from the program control board or programmer. DRAIN PUMP, 60 HZ Part no.: 8801167 Resistance: 76 Ω Current: 0.3 A, 28 W on load The drain pump is combined with an integrated needle trap, which can be cleaned by the user. If the drain pump has run for 180 seconds during emptying, the program is stopped, reset to zero and a fault code is indicated on the display. On models W620/W600, this will be indicated by "S" on the Program Control Knob. On models W640/W660, it will display on the LED window. LEVEL SWITCH Part no.: 80 617 47 An electromechanical level switch operates at two levels, see the electrical schematic diagram. It checks the water level and starts the drain pump if overfilling is indicated. LEVEL SENSOR Part no.: 80 616 64 ASKO Level sensor type 1166. Voltage: To sensor in W620: 0.5 V out from the sensor at zero pressure and 230 V mains voltage To sensor in W640/W660: 0.5 V out from the sensor at zero pressure and 230 V mains voltage Measurement at program/control unit The level sensor is located on the electrical component bridge and connected to the PCU, see the electrical schematic diagram. RADIO INTERFERENCE FILTER 50/60 Hz Part no.: 80 585 58 Leakage Current: 230 V/ 50 Hz 0.3-0.4 mA Leakage Current: 240 V/ 60 Hz 0.3-0.4 mA 13
