    3.- PROGRAMME EXECUTION 3.1.- Programme execution. In order to carry out a wash programme, the following steps must be followed: Put the dirty clothes in the washer-extractor drum. Close the washer extractor door Press the main switch (1) fig. 9. The pilot lights on. When connecting the programmer, and after each self diagnosing phase, the latter is ready for choosing a programme.
  • Page 30 NOTE: During the heating and load/discharge of water, the safety timer WDT is activated, which controls the whole machine. If it reaches its time, an alarm message will be displayed on the screen, indicating that some of the heating, load or discharge phases have not been completed within the maximum allowed time.
  • Page 31 SLOWING DOWN The slowing down procedure is called during the spin cycle, only when the slow or fast spin engine is activated: 1.-In case of swinging 2.-When the ADVANCE key is pressed 3.-When the STOP key is pressed 4.-During the reinitialization process after a disconnection 5.-When the time for a step ends The slowing down is variable, it depends on the time passed since the engine start and if the engine spins fast or slow.
  • Page 32 POWER DOWN If during the execution of a programme a power failure of less than 1 second occurs, this failure will be ignored. If the power failure lasts more than 1 second, the machine will stop. When the power supply comes back the screen displays "RE-START CYCLE ?" and the POWER-DOWN LED of the front panel (signal 3) lights on.

  • Page 47: Faults Indication

    5.- FAULTS INDICATION The device is constantly controlling the state of temperature and level transductors in order to avoid faults during operation due to the wear of the same. Furthermore, the use of safety timers (WDT), which set a time limit to the water load, discharge and heating phases, avoids possible faults caused by a lack when it comes to filling or emptying the tub or failure to reach the temperature level.
  • Page 48 The most likely causes in this case may be: during the load phase: 1.-Fault in the water inlet solenoid valve 2.-There is no water in the supply line or the flow is very low. 3.-The discharge valve could be clogged, open or closed. 4.-Defective connection between the tub and the level sensor In this case the operator can decide whether to continue with the process, with a reduced water load, by pressing START, or stop the washing process by pressing RESET.

    6.- SERVICE FUNCTIONS MAINTENANCE WARNING The machine requires automatically the intervention of the maintenance service when reaching a certain number of preselected washes (programmes), through the message: MAINT. REQ. This message is displayed at the beginning of each programme, and it is repeated in each successive START until the maintenance technician disables it.
