If your Wolf Boiler shows 'DHW sensor faulty', it means that the DHW sensor (cylinder sensor) or sensor lead has a short circuit or break, or the DHW-sensor temperature is above 99 °C. Check the leads and plug-in connections of the DHW temperature sensor. If they are OK, replace the sensor.
What to do if flue gas sensor is faulty in Wolf CGB-2-24 Boiler?
If your Wolf Boiler displays 'Flue gas sensor faulty,' it indicates that the flue gas sensor or sensor lead has a short circuit or break. Check the leads and plug-in connections of the flue gas temperature sensor. If the electrical connection is OK but there is no function, replace the sensor.
How to fix eHLSC sensor faulty on Wolf Boiler?
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?
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-2-24?
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.
How to fix HLSC excess temp on Wolf Boiler?
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 there is flame failure in Wolf Boiler?
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.
