Possible cause or remedy
•
Temperature of CTS sensor already higher than the
maximum possible desired value (sensor not
inserted into food correctly)
•
Foaming in the steam generator when cooking (due to
e.g. wrong, non-original CONVOTHERM cleaning
agents)
•
Calcification of the steam generator
•
Boiling dry of the immersion heaters due to double
level sensor's short circuit to earth
•
Water reservoir in the condenser too hot:
a) Tap closed
b) Appliance connected to hot water
c) Solenoid valve "condenser cooling" defective
d) Coil from the solenoid "condenser cooling"
defective
e) Inlet filter in the solenoid valve contaminated
f) Quenching nozzle in the condenser/siphon blocked
•
Demoisturisation flap faulty
a) Stiff
b) Motor contact
c) Motor defective
d) Flap blocked
e) Cable defects (contact / motor)
•
Sensor wiring interrupted (plug X16 of the control
module)
•
Oven sensor (B6) interrupted (defective)
•
Thermoelement sensor (B6) has contact with
appliance housing
•
Thermoelement (B6) defective
•
Sensor wiring interrupted (plug X16 of the control
module)
•
CTS sensor (B10) interrupted (defective)
•
Sensor wiring interrupted (plug X16 of the control
module)
•

defective)
thermoelements
•
Sensor wiring interrupted (plug X16 of the control
module)
•
CTS sensor (B10) interrupted (more than 2
defective)
