What does the 06 error mean on an Immergas boiler?

The 06 error on an Immergas boiler indicates a domestic hot water probe anomaly. The NTC temperature sensor measuring hot water temperature is reporting incorrect readings or has failed. The boiler may continue to provide heating but hot water production will be affected. Switch off the boiler at the electrical supply. Wait 30 seconds and switch back on to reset. If the error persists, contact a qualified technician for probe testing and replacement.

What does the 24 error mean on an Immergas boiler?

The 24 error on an Immergas boiler indicates a push button control panel anomaly. The main circuit board has detected a fault with the user control panel. Switch off the boiler at the electrical supply. Wait 30 seconds and switch back on to reset. If normal conditions are restored, the boiler should restart automatically without requiring a manual reset. If the error persists, contact a qualified technician for control panel diagnosis.

What does the 203 error mean on an Immergas heat pump?

The 203 error on an Immergas heat pump indicates a communication error between the inverter and main control board lasting more than six minutes. Switch off the heat pump at the isolator switch for five minutes. Switch back on and monitor for the error. If the error persists, contact a qualified technician. This fault may require inverter board inspection or replacement.

What does the 440 error mean on an Immergas heat pump?

The 440 error on an Immergas heat pump indicates central heating operation has stopped because the outdoor temperature exceeds 36 degrees Celsius. This is normal protective behaviour, not a fault. The heat pump will automatically resume heating operation when outdoor temperatures fall to within normal operating range. No action is required. The unit should resume normal operation as conditions change.

What does the 404 error mean on an Immergas heat pump?

The 404 error on an Immergas heat pump indicates the overload prevention protection has activated on the outdoor unit. The system has detected conditions that could damage the compressor and has shut down protectively. Allow the unit to rest for 30 minutes. Check that nothing is obstructing the outdoor unit airflow. Switch off at the isolator, wait five minutes, then restart. If the error returns immediately, do not continue resetting. Contact a qualified technician for diagnosis of the overload cause.

What pressure should my Immergas boiler system maintain?

The boiler pressure gauge should read a value between 1.0 and 1.2 bar when the system is cold. This is the optimal operating range for most Immergas boilers.

What periodic maintenance does my Immergas heat pump need?

Periodic maintenance includes visually checking for water leaks or oxidation on connections, verifying that safety devices have not been tampered with, and ensuring the outdoor unit remains free of debris. Check that drainage for condensate and defrost water is clear.

Why are some radiators not heating up when my Immergas boiler is running?

If some radiators remain cold while the boiler is running, trapped air may be the cause. Bleed each cold radiator using a radiator key by opening the bleed valve until water flows steadily, then close it. Ensure all radiator valves are open. Check that the system pressure is between 1.0 and 1.5 bar after bleeding. If radiators remain cold after bleeding, or if multiple radiators are affected, contact a qualified technician as there may be a circulation pump fault or system blockage.

What should I do if I smell gas near my Immergas boiler?

If you smell gas, do not operate any electrical switches, lights, or the boiler controls. Do not use any naked flames or electronic devices. Open windows and doors to ventilate the area only if it is safe to do so. Do not attempt to locate the source of the leak. Leave the property immediately and take all occupants with you. Once safely outside, call the gas emergency service. Do not re-enter the property until it has been checked and declared safe by a Gas Safe registered engineer.

How do I repressurise my Immergas boiler?

Locate the filling loop beneath or near your boiler. Open both valves slowly to allow cold mains water into the system while watching the pressure gauge. When it reaches between 1.0 and 1.2 bar, close both valves securely.
