4.6 Notes on the behaviour of certain alarms

Configuration alarm E93: when this alarm is detected (on switching on the appliance), the appliance
stops, the LEDs in the START/PAUSE button start to flash, displaying the complete code (family plus
alarm), the display shows the alarm code provided the relevant configuration part is intact.
It will not be possible to access diagnostics mode and the only available option is to turn the appliance off.
Configuration alarm E94: the LEDs in the START/PAUSE button start to flash, displaying the complete
code (family plus alarm) and the code is also shown on the display.
The diagnostics mode cannot be accessed and the "quick alarm viewing" mode cannot be used.
Alarms EH1-EH2-EH3: in the event of problems with the supply voltage, the appliance remains in alarm
status until the mains frequency or voltage returns to acceptable values or the appliance is switched off
(programme selector set to "0"). Only the family of the alarm "H" is displayed if the problem occurs during
normal appliance operation. The family plus the alarm are displayed if the problem occurs when the
appliance is switched on. The LEDs above or in the START/PAUSE button flash and the code is
concurrently shown on the display.
The diagnostics mode cannot be accessed and the "quick alarm viewing" mode cannot be used: the alarm can
only be read in full when the situation has normalised.
Alarms E51- E52: all the alarms are displayed during diagnostic testing: normally, when shifting from one
control phase to another, the appliance quits the alarm mode and executes the selected phase. This is not
the case for alarms E51 (motor power supply TRIAC short-circuiting) and E52 (no signal from motor
tachometric generator): the only choice to quit the alarm mode is to turn the programme selector to position
"0" (reset).
