Possible causes
• Missing water in the
boiler;
• Limestone accumulation
in the boiler;
• Wrong insertion of the
TC probe sensor;
• The safety thermostat
bulb or the capillary are
damaged;
• Leakage of heat in the
safety thermostat body
area;
• The parameter BOT is
set too high;
• Room temperature <5°C.
• The cavity is dirty;
• The parameter COT is
set too high;
• The safety thermostat
bulb or the capillary are
damaged;
• The motor fan is blocked
while the heat is still On;
• The temperature TC
sensor provides erratic
measurements
• Leakage of heat in the
safety thermostat body
area.
• Room temperature <5°C.
• Missing water in the
boiler (electric heated
appliances only);
• Limestone accumulation
in the boiler;
• The parameter BOT is
set too low.
• The cavity is dirty;
• The parameter COT is
set too low.
Misuse
Diagnostic according to
error number (from 00 to 17)
displayed.
• Water supply valve
closed or partly closed;
• Temporary lack of water
supply pressure;
• Boiler water level sensor
failure;
• Boiler leakage: drain
valve or fracture.
Actions
The oven is not able to produce steam with the
boiler. An alternative device will be used, but the
performance will be reduced;
• Call service to restore the boiler functionality.
Manually clean the oven cavity and call Service.
• Wait for the boiler temperature to cool down
(alarm ETUB will disappear)
•
Run a cleaning program including the rinse
and descale cycle and use 2 tabs C25 only.
(Follow the procedure as per User Manual)
• In case the alarm re-appears, descale the
boiler again.
• If the problem persists, call Service.
• Launch a cooling cycle; if not possible open
the door and let the oven to cool down; clean
the cavity.
• When the temperature drops it is possible to
launch a new cooking cycle.
• If the error shows up again call Service.
Restore the air inlet filter checking its cleanness
before fitting it back in place. In case the filter is
lost, call Service
Switch the oven OFF/ON;
If the error persists, manually clean the oven
cavity and call Service.
• Ensure the water supply valve is fully open
and the water filter has no obstructions (clean
it if needed).
• The oven can continue to work in Convection
mode
• Unless the water is missing from the mains,
the oven can continue to work in recovery
mode.
• Call Service to restore boiler functionality.
