FAILURE 35: WRONG SOFTWARE VERSION
When a total new software that isn’t downward compatible with previous software versions is loaded, then the software will detect that the old and new softwares are not compatible.
You have to reconfigure the Full Control Dryer Computer.
! ATTENTION !!!
ALL THE CUSTOM SETTINGS WILL BE ERASED IN THE FULL CONTROL DRYER COMPUTER BY LOADING THE FACTORY SETTINGS.
After reinitialization of the Full Control Dryer Computer, fault 35 can only be erased by switching the power Off/On.
FAILURE 36: TOO HOT END
Failure 36 occurs when the actual cooldown temperature at the end of the dry cycle is still above 78°C.
If at the end of the drying cycle the temperature is above 78°C the dryer will go on with the cooldown sequence for 60 minutes (or until temperature below 65°C or until open door) . If the temperature is still above 70°C after these 60 extra minutes cooldown Failure 36 is generated.
On the display will be shown „Hot“ and the air temperature as indication that there is something wrong.
