Why calibration factory limit not reached on Wolf CGB-2K-24 Boiler?
- L
  Lisa BrownSep 7, 2025
  If your Wolf Boiler displays 'Calibration factory limit' and the minimum limit was not reached, it could be due to flue gas recirculation issues. Check the flue path inside and outside the appliance for any leaks or blockages. Additionally, have customer service set the IO default value to the factory setting. Another possible cause is a corroded or bent ionization electrode, so check its condition and clean or replace it if necessary. Lastly, a wiring error on the HCM-2 (low voltage side) could be the culprit, so check the electrical connection of the HCM-2 low voltage side.

What to do if there is flame failure in Wolf CGB-2K-24 Boiler?
- S
  Sarah DixonAug 23, 2025
  If the Wolf Boiler shows a 'Flame failure' error, it could be due to several reasons. First, verify the gas type setting on both the gas valve and the AM/BM. Then, check the gas supply pressure. Inspect the condition of the ionization electrode, cleaning or replacing it if necessary, and ensure its gap and position are correctly set. Finally, examine the flue path inside and outside the appliance for any leaks or blockages.

How to fix HLSC excess temp on Wolf CGB-2K-24 Boiler?
- J
  Joanne BennettAug 26, 2025
  If your Wolf Boiler displays 'HLSC excess temp,' it indicates that the temperature at the heat exchanger cover has exceeded 185 °C. Check the cables and plugs connected to the high limit safety cut-out (HLSC). If the electrical connections are fine but there's still no function, replace the HLSC. Another possible cause is a contaminated combustion chamber, in which case, clean or replace the combustion chamber.

What to do if TL excess temp on Wolf CGB-2K-24?

  esparzakathyAug 27, 2025
  If your Wolf Boiler shows a 'TL excess temp' error, it means one of the temperature sensors eHLSC1 or eHLSC2 on the combustion chamber has exceeded the high limit safety cut-out limit (108 °C). Check the system pressure and vent the heating circuit. Inspect the cables and plugs of the temperature limiter (eHLSC), and if they are OK but there's no function, replace the eHLSC. Also, check if the pump is running; if not, check its cables and plugs, and if the electrical connection is OK but it's still not working, replace the pump.

What to do if boiler sensor is faulty in Wolf Boiler?
- K
  Kelly HardyAug 27, 2025
  If your Wolf Boiler displays the message 'Boiler sensor faulty' it could be due to excess temperature in the flow (Boiler sensor > 100 °C). First, check if the pump is running. If it is not, check the cables and plugs and if the electrical connection is OK but there is still no function, replace the pump. Another solution is to increase the minimum pump speed. Also, check the leads and plug-in connections of the boiler sensor, and if they are OK but there is still no function, replace the boiler sensor.

How to fix eHLSC sensor faulty on Wolf Boiler?
- C
  Christine GomezAug 29, 2025
  If your Wolf Boiler indicates 'eHLSC sensor faulty', it means that the temperature sensor eHLSC1, eHLSC2 on the combustion chamber or sensor lead has a short circuit or break. Check the leads and plug-in connections on the eHLSC on the combustion chamber. If the electrical connection is OK but there's no function, replace the eHLSC.

Why is there calibration discrepancy on Wolf CGB-2K-24?
- S
  Stephanie NolanSep 9, 2025
  If your Wolf Boiler shows 'Calibration discrepancy', it could be due to several reasons. One possibility is a corroded or bent ionization electrode, so check its condition and clean or replace if necessary. Another cause could be soot or dirt particles in the intake air, especially in room-sealed operation. Also, check for flue gas recirculation issues by inspecting the flue path inside and outside the appliance for leaks or blockages. Lastly, a wiring error on the HCM-2 (low voltage side) could be the cause, so check the electrical connection of the HCM-2 low voltage side.

Why is fan speed high on Wolf CGB-2K-24 Boiler?
- T
  Tami HallSep 6, 2025
  If the Wolf Boiler displays 'Fan speed >', it means the fan does not stop. Check the fan's cables, plug-in connections, power supply, and switching. If the fault occurs repeatedly, replace the fan.

  John WhiteSep 3, 2025
  If your Wolf Boiler displays 'Outside sensor faulty,' it means that the outside sensor or sensor lead has a short circuit or break. For the eBus outside temperature sensor, refer to its instructions. Similarly, for a wireless outside sensor, consult its specific instructions.
