4.3 PHASES OF THE DIAGNOSTIC CYCLE Irrespective of the type of PCB and the configuration of the programme selector it is possible, after entering diagnostic mode, to perform diagnostics on the operation of the various components and to read the alarms by turning the programme selector clockwise . All the alarms are enabled during the diagnostic cycle. (*) In most cases, this time is sufficient to check the heating. However, the time can be increased by repeating the phase without draining the water: pass for a moment to a different phase of the diagnostic cycle and then back to the heating control phase (if the temperature is higher than 80°C, heating does not take place).
(**) The check at the maximum speed occurs without control of the FUCS and no clothes have to be inserted inside the appliance.
