What does the 04 error mean on an Immergas boiler?

The 04 error on an Immergas boiler indicates a contacts resistance block, meaning there is a fault detected in the gas valve electrical supply circuit. If you smell gas, do not operate any switches, ventilate the area if safe to do so, leave the property immediately, and call the gas emergency service from outside. If there is no gas smell, switch off the boiler at the electrical supply. Do not attempt to reset. Contact a Gas Safe registered engineer for professional diagnosis and repair of the gas valve circuit.

What does the 320 error mean on an Immergas heat pump?

The 320 error on an Immergas heat pump indicates an OLP sensor error. The overload protection sensor on the compressor has detected a fault. Switch off the heat pump at the isolator switch. Do not attempt to reset repeatedly. Contact a qualified technician with F-Gas certification for compressor and sensor inspection. This protection system prevents compressor damage from electrical overload.

What does the 01 error mean on an Immergas boiler?

The 01 error on an Immergas boiler indicates an ignition failure block. The boiler has attempted to ignite but failed within the preset time. If you smell gas, do not operate any switches, ventilate the area if safe to do so, leave the property immediately, and call the gas emergency service from outside. If there is no gas smell, check that the gas supply is turned on and other gas appliances are working. Press the reset button once only. If the error recurs after reset, do not attempt further resets. Contact a Gas Safe registered engineer for professional diagnosis.

What does the 231 error mean on an Immergas heat pump?

The 231 error on an Immergas heat pump indicates a condensation temperature sensor malfunction. The sensor monitoring refrigerant condensation temperature has failed or is reporting incorrect values. Switch off the heat pump at the isolator switch. Contact a qualified technician with F-Gas certification for diagnosis. This sensor is critical for efficient heat pump operation and refrigerant circuit protection.

What does the 202 error mean on an Immergas heat pump?

The 202 error on an Immergas heat pump indicates a sustained communication error between the control kit and outdoor unit lasting more than three minutes. Switch off the heat pump at the isolator switch for five minutes. Switch back on and monitor for the error. If communication is not restored, contact a qualified technician. Do not repeatedly reset the unit as this will not resolve a wiring or component fault.

How should I protect my Immergas heat pump outdoor unit during winter?

Maintain a clear space of at least 60 centimetres around the outdoor unit at all times. After snowfall, gently brush away any snow accumulation from around the unit using a soft broom. Never use sharp objects to remove ice or snow as this can damage the coil fins. Do not cover the unit or stack anything on top of it as this restricts airflow. Some frost on the unit is normal and the automatic defrost cycle will handle this. If the unit remains frozen for more than a few hours, contact a qualified technician.

How do I reset my Immergas boiler?

Locate the reset button on your boiler's control panel, typically marked with a flame symbol or the word Reset. Press the button firmly. On most Immergas models, holding the button for approximately 5 seconds will initiate a restart. If the error clears, the boiler should resume normal operation. If the boiler does not reset or the same error returns, do not repeatedly press the reset button. Contact a qualified technician for diagnosis.

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.

What do the symbols on my Immergas boiler display mean?

During normal operation, the display shows a green illumination with symbols indicating boiler status. The display typically shows the current water temperature. A flame symbol indicates the burner is active. A tap symbol relates to domestic hot water functions. A radiator symbol relates to central heating. Error codes appear as numbers or letter-number combinations when faults occur. When on standby, a horizontal segment appears. Consult your specific model manual for detailed symbol meanings as they can vary between models.

How does the defrost function work on my Immergas heat pump?

The heat pump automatically enters defrost mode when ice builds up on the outdoor unit's evaporator coil. During defrosting, the system reverses briefly to melt the ice, then returns to normal operation.
