7.3 Diagnostics phases
Irrespective of the type of PCB (i.e. with horizontal or vertical buttons) and the configuration of the
programme selector it is possible, after entering diagnostics mode, to perform diagnostics on the operation
of the various components and to display the alarms by turning the programme selector
clockwise
.
All the alarms are enabled during the diagnostics 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 diagnostics
cycle and then back to the heating control phase (if the temperature is higher than 80°C, heating does not
take place).
