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.

  If the Wolf Boiler displays 'No flame established', it could be due to several reasons. First, ensure the gas supply is properly connected and the gas valve is open. Next, inspect the ionization electrode for its position and condition, adjusting or replacing it if needed. Also, check the position of the ignition electrode and adjust if necessary, along with examining the ignition transformer and wiring. Verify that the HG44 curves are set to the standard value. Finally, check that the gas valve opens; if it doesn't, check the cables and plugs and repeat the test. If the gas valve is faulty, replace it.

  If your Wolf Boiler displays 'Return sensor faulty', it indicates that the return sensor or sensor lead has a short circuit or break, or the return sensor temperature is above 100 °C. Check the leads and plug-in connections of the return sensor. If they are OK and there is still no function, replace the return 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.

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.

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