5.6 Notes concerning certain alarm codes

Configuration alarms E93: If this alarm is generated (when the appliance is switched on), operation of the appliance is blocked, the LEDs placed above or
inside the START/PAUSE button start to flash displaying the complete codification (family plus alarm), the display shows the alarm code on condition that
the configuration part of the display is ok.
The diagnostic procedure cannot be accessed; the only option is to switch the appliance OFF.
Configuration alarm E94: all LEDs placed above or inside the START/PAUSE button start to flash displaying the complete codification (family plus alarm)
and the code is displayed.
It is not possible to enter the diagnostics or to use the mode "rapid displaying of the alarm".
Alarms EH1(Eb1)-EH2(Eb2)-EH3(Eb3): In the event of problems with the mains power supply, the appliance remains in alarm mode until the mains
frequency or voltage are restored to the correct value or the appliance is switched off (programme selector on "0"). The family of alarm "b or H" only is
displayed if the problem occurs during the normal operation of the appliance, while the family plus the alarm are displayed if the problem occurs at the
switching on, through the flashing of the LEDs placed above or inside the START/PAUSE button. At the same time the code is represented also in the display.
It is not possible to enter the diagnostics or to use the mode "rapid displaying of the alarm": the complete alarm can be read only when the abnormal situation has
terminated.
Alarms E51- E52: During the diagnostic test, all the alarms are displayed. Normally, when the programme selector is turned from one test phase to another,
the appliance exits the alarm condition and performs the phase selected. This does not take place in the case of alarms E51 (power triac on motor short-
circuited) and E52 (no signal from the tachometric generator on the motor): in these cases, the only option to exit the alarm condition is to switch the appliance
OFF by turning the selector to position "0" (reset) or pushing the ON/OFF button (INPUT styling).
