Common Immergas Faults in Millfield
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 15 error mean on an Immergas boiler?
The 15 error on an Immergas boiler indicates a configuration error. The control board has detected an electrical wiring anomaly or an incompatibility in the system configuration. The boiler will not start until this is resolved. Switch off the boiler at the electrical supply. Do not attempt to reset or reconfigure the boiler yourself. Contact a qualified technician to diagnose the wiring fault and correct the configuration settings.
What does the 221 error mean on an Immergas heat pump?
The 221 error on an Immergas heat pump indicates an outdoor unit temperature sensor malfunction. The temperature sensor on the outdoor unit is reporting incorrect readings or has failed. 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 for sensor testing and replacement.
What does the 03 error mean on an Immergas boiler?
The 03 error on an Immergas boiler indicates the flue safety thermostat has activated due to excessive flue gas temperature. This is a critical safety feature detecting potential flue obstruction or combustion problems. Do not attempt to reset or override this safety feature. Do not use the boiler. Ensure the room is well ventilated. Contact a Gas Safe registered engineer immediately as flue problems can lead to carbon monoxide exposure, which is potentially fatal. Do not delay professional inspection.
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.
Frequently Asked Questions
When does electrical integration (backup heating) activate on my Immergas heat pump?
Electrical integration activates automatically in certain conditions, including during defrost cycles and when outdoor temperatures are very low. The system controller determines when supplementary heating is needed to maintain target temperatures. If the heat pump alone cannot meet the heating demand within a reasonable time, the backup electric resistance provides additional heating capacity.
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.
How often should my Immergas boiler be serviced?
The heating system should be serviced at least once a year. Additionally, a combustion test (flue test) should be carried out at least once every two years to ensure optimal safety, performance and operation.
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.
Why does my Immergas boiler keep losing pressure?
Frequent pressure loss typically indicates a problem that requires professional diagnosis. Common causes include small leaks in the heating system pipework or radiator valves, a faulty pressure relief valve, or a problem with the expansion vessel. If you need to repressurise more than once every few months, contact a qualified technician to identify and repair the underlying cause. Do not ignore persistent pressure loss as it can lead to boiler damage or system failure.
