ACF
Warning
Air filter absent
• Filter not detected;
• Possible damage to inter-
nal electric and electronic
components due to air
filter absence.
• Refit the filter;
• If the problem persists call Service.
ACUM
Stops oven
Main electronic board
not identified

with the main electronic
board.
• Switch the oven OFF/ON;
• If the error persists, call Service.
ASCH
Warning
Component compart-
ment temperature
warning
• Filter is dirty;
• Too high room
temperature.
• Check room temperature considering the
oven needs fresh air to cool electronic
compartment.
• Clean the filter;
• Allow oven to cool before cooking;
• If the problem persists, call Service

BEtr
Warning
Boiler excessive tem-
perature raising time
The oven has detected a
low performance in the
boiler.
• It is possible to cook. Verify the cooking
results.
• If the warning persists call Service.
Bhtc
Warning
Warning on excessive
time on closing
operation
• Flap (venting valve)
motoreducer or micro
switch failure.
• Obstruction at the vent-
ing valve inlet.
It is possible to continue using the oven. Cooking
results maybe different from usual.
• With the oven OFF and cold, check if any
obstruction at the ventilation chimney on the
top of the oven: remove the obstruction if any;
• If the problem persists, call Service.

bntC
Stops
boiler
Boiler SSR NTC failure
(NTC4)
Temperature sensor issue.
The oven has detected a problem with boiler
operation.
• Verify cooking results.
• If the problem persists, call Service.
BoLt
Stops cycle
(if the cycle
needs the
boiler)
Boiler water loading
timeout
• Water supply (pressure/
quality of water).
• Electric insulation prob-
lem with water level
sensors.
• Check if the water supply is open;
• Check if the water pressure is not too low;
• Verify if the water filter is clogged. Clean it or
replace it;
• Mechanical problem with boiler operation. If
the problem persists call Service.
BSHt
Warning
Boiler SSR NTC
(NTC4) high
temperature
• Inlet air filter dirty;
• Cooling fan failure;
• Cooling inlet air sucking
warm/hot air;
• Oven installed by hot
machine;
• Steam/Heat leakage in
the electronic
compartment;
• Do not switch the oven Off;
• Wait for the temperature to decrease;
• Clean the inlet air filter;
• Check with a thin strip of paper whether a
consistent air flow can be detected at the
cooling air inlet: if not, call Service;
• Check if the inlet cooling air may be affected
by heat produced in the kitchen (in case the
oven is located by hot appliances, stop work-
ing with those appliances and inform
Service);
• If the error persists, call Service.
