7.3 Diagnostic test phases
Irrespective of the type of PCB and the configuration of the programme selector, after entering the diagnostic
mode, turn the programme selector
clockwise
to perform the diagnostic cycle for the operation of the various
components and to read any alarms (all alarms are enabled in the diagnostic cycle).

Reading/Cancellation of the

----- ----
(*)
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 garments must be inside the appliance.
