3.3 Diagnostic test phases
Irrespective of the type of electrical board and of the selector configuration, once the diagnostics system
has been activated, turn the selector knob clockwise to run a check of the various components (as
described in table 1) and read the alarms.
A control code for the selector (or the second selector, where applicable) is shown at the same time: in
stylings A3 and Z3 on the display for two seconds, before displaying what is described in the last column of
the table below, whereas in stylings A5/6, Z5/6 and K6.2 the code is displayed by lighting the LEDs for
three seconds (see table 2 and 3).
All alarms are enabled in 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 AGS and no garments must be inside the appliance.
