24 • SELF-DIAGNOSIS AND FAULT IDENTIFICATION
• whenever the appliance is powered
up by pressing the main switch (1) , an
electronic diagnostics routine is run
automatically to check the principal
functions. Assuming the appliance is in
perfect working order on completion of
the self-diagnosis routine, the display
shows the main menu.
• If any irregularities are discovered, on
the other hand, these are indicated on
the display.
• Alarms are divided into two categories
based on the type of fault.
“SERIOuS” alarms are signalled by a
window with the message “ALARM”
and a steady acoustic signal; these halt
the oven completely and shut down all
functions.
“NON SERIOuS” alarms are indicated
by a window with the message
“CAuTION” and an intermittent
acoustic signal; they only block the
function specifically related to the alarm
condition.
The acoustic signal stops automatically
when the alarm condition ceases to
exist, while the operator must press
“BACK” to close the alarm window.
Error codes are extremely important
when trouble cannot be remedied by
the operator, since they give the service
technician an indication as to the nature
of the fault.
