is advisable to run a check on the programmed data.
You can now re-start the interrupted program.
If, of course, the cause of the alarm is not removed the same problem will occur as soon as the oven
is put back in use.
D. If the thermocouple breaks the following occurs:
• the flashing legend "tEmP" appears on the display (11).
• an overheating warning buzzer sounds.
• the elements are switched off.
In this event the thermocouple must be changed.
Should even just one of the control and safety devices fail to operate properly
proceed – as far as is possible – as described in section 9.2 and contact you nearest
Authorised Servicing Centre.
To ensure that the oven cycle ends in accordance with the duration displayed at the end of PHASE 5
during programming, the operator must observe the maximum in-oven temperature increases
