Error description
Possible cause or remedy

E12.4
ID=28
Core temperature
sensor 4 - excessive
temperature
• Temperature of CTS sensor already higher than the
maximum possible desired value (sensor not
inserted into food correctly)
  
E13.0 Steam generator (B4
thermoelement)
Excessive
temperature (if
temperature
measured in the SG
>120°C)
• 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

(B3- thermoelement)
excessive
temperature
(if temperature in
the condenser
measured > 100°C)
• 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

