F.1 Interruption return sensor NTC connector not plugged in or loose,
NTC defective,
multi-plug on the electronics not plugged in properly
F.10 Short circuit supply sensor NTC defective,
short-circuit to ground/short circuit in the cable harness
F.11 Short circuit return sensor NTC defective,
short-circuit to ground/short circuit in the cable harness
F.13 Short circuit cylinder sensor NTC defective,
short-circuit to ground/short circuit in the cable harness,
inside of the plug damp
F.20 Water safety thermostat supply or return NTC defective (intermittent contact),
supply temperature too high,
earth connection of the cable harness to
the appliance not correct,
failed discharge to the electrode via ignition cable, ignition plug or ignition
electrode
F.22 Dry burning (no water in the
appliance) no water in the primary heat exchanger when commissioning,
RESET activated when appliance is hot,
water pressure switch has been triggered, flow switch has been triggered
F.23 Lack of water
Temperature spread too large
System not bled properly pump jammed, reduced output of the pump,
air in the appliance, system pressure too low,
supply and return NTC mixed up,
appliance not filled via appliance-internal KFE cock (fill only via return!),
start venting program
F.24 Lack of water
Temperature rise too fast
System not bled correctly pump jammed, reduced output of the pump,
air in the appliance, system pressure too low,
supply and return NTC mixed up,
appliance not filled via appliance-internal KFE cock (fill only via return!),
start venting program
F.25 Flue safety thermostat flue tempera-
ture too high, system pressure too low plug connector option flue gas thermostat interrupted,
water pressure switch has been triggered, flow switch has been triggered
F.27 Flame simulation (flame signal despite
gas valve being switched off) gas solenoid valve leaking,
electronics (flame detector defective), dampness on the electronics
F.28 No ignition when starting no or too little gas,
ignition system (ignition transformer, ignition cable, ignition plug) defective,
interruption of the ionisation current (cable, electrode),
false gas setting, faulty earthing of the appliance, electronics defective
F.29 No reignition gas supply temporarily interrupted, flue gas recirculation,
faulty earthing of the appliance
F.32 Speed deviation fan
(too large when starting) fan jammed,
fan plug not inserted correctly,
fault in cable harness, electronics defective
F.37 Speed deviation fan
(too high or too low during operation) pressure sensor not fitted or defective
(however, not short circuit or interruption)
F.42 Short circuit coding resistance no valid value for appliance variant
F.43 Interruption coding resistance no valid value for appliance variant
F.60 Gas valve control
“+” faulty short circuit/short-circuit to ground in the cable harness to the gas valves,
gas fitting defective (short-circuit to ground of the coils), electronics defective,
water pressure switch defective, flow switch defective
F.61 Gas valve control
“-” faulty Short circuit/short-circuit to ground in the cable harness to the gas valves,
gas fitting defective (short-circuit to ground of the coils), electronics defective
water pressure switch defective, flow switch defective
F.62 Gas valve shut-off faulty gas fitting leaking, electronics defective
F.63 EEPROM faulty electronics defective
F.64 Electronics/sensor fault short circuit supply or return NTC, electronics defective
F.65 Electronics temperature too high electronics too hot due to external influence, electronics defective
F.67 Electronics error flame
(implausible flame signal) electronics defective
Emergency
run
“speed” Special message:
no speed signal from the fan fan (hall sensor) defective, error in the cable harness, electronics defective
