Fault Codes
Note: Fault messages dependent on boiler equipment level

Displayed fault code

| System characteristics| Cause| Measures
---|---|---|---
F.13| Regulates as if the outside temperature were 0°C.| Lead break, outside temperature sensor|

•  Check the operating mode setting in the commissioning assistant and correct if necessary.
• Check outside temperature sensor and connection to sensor (external plug, contacts 1 and 2).
• Measure voltage at sensor input on electronics module.

Target value: 3.3V– with sensor disconnected. Replace faulty component if necessary.

F.69| Burner in a fault state| Ionization current lies outside the permissible range| Check ionization electrode:

•  Check whether insulation block is touching electrode ceramic.
• Check gas solenoid valve: Activate “Minimum heating output” for approx.  4 min in actuator test. If this causes a fault to occur, replace BCU burner control unit.
• In the actuator test, switch from “Minimum heating output” to “Maximum heating output”. If this fault occurs during modulation, check the intake screen for contamination.

Replace the fan unit if necessary.

F.70| Burner in a fault state| Internal error burner control unit| Replace BCU burner control unit:
See page 89.
F.71| Burner in a fault state| Fan speed too low|

•  Check fan for blockage.
•  Check the gas type and flue system setting in the commissioning assistant and correct if necessary. Reset the boiler.

F.72| Burner in a fault state| Fan idle state not reached| Reset the boiler.
If fault occurs repeatedly, replace fan unit.
F.73| Burner in a fault state| Internal communication error| Reset the boiler. If fault recurs, replace BCU burner control unit: See page 89.
F.182| No DHW heating| Short circuit, outlet temp. sensor (if installed)| Check outlet temperature sensor (plug X1, cores 13 and 14). Measure sensor input on electronics module. Target value: 3.3V– with sensor disconnected
F.183| No DHW heating| Lead break, outlet temperature sensor (if installed)| Check outlet temperature sensor (plug X1, cores 13 and 14).
F.299| Time/date incorrect| Real time clock setting incorrect| Set the time and date.
F.373| Burner in a fault state| Heat transfer too low during calibration Temperature limiter has shut down.|

• Ensure adequate heat transfer.
• Check circulation pump for faults, scale or blockages.
• Check 3-way diverter valve function in actuator test.

Vent the system.

•  Check function of flow sensor. Reset the boiler.

F.378| Burner in a fault state| Flame loss during stabilization or operating phase|

• Check gas supply (gas pressure and gas flow switch).
• Check flue gas recirculation.
• Check for contamination of ionization electrode and burner gauze assembly. Reset the boiler.

F.379| Burner in a fault state| Flame signal not present or insufficient|

• Check ionization electrode connecting cable for damage and firm seating.
• Check ionization electrode; replace if necessary. Reset the boiler.

F.380| Burner in a fault state| Flame loss immediately after flame formation (during safety time)| Check gas supply (gas pressure and gas flow switch). Check balanced flue system for flue gas recirculation. Check ionization electrode and burner gauze assembly:

• Clearance to burner gauze assembly
• Contamination on electrode Reset the boiler.

F.381| Burner in a fault state| Flame loss during operating phase| Check gas supply (gas pressure and gas flow switch). Check balanced flue system for flue gas recirculation. Check ionization electrode and burner gauze assembly:

• Clearance to burner gauze assembly.
• Contamination on electrode Reset the boiler.

F.446| Burner in a fault state| Deviation, boiler supply
temperature sensor/high limit safety cutout| Check the supply temperature sensor/high limit safety cut-out. Check plug-in connection and lead to sensor.
Reset the boiler.
F.467| Burner in a fault state| Gas supply insufficient during calibration. Contaminated or insufficiently sized gas line.|

• Scan for  Test static gas pressure and gas flow pressure.
• Check that on-site gas line and gas flow switch are correctly sized.
• Visually inspect gas solenoid valve inlet and strainer on the inlet side for contamination. Reset the boiler.

Note: Contamination from a brazed gas line, for example, can block up the gas solenoid valve strainer on the inlet side.
