What to do if the fan speed on my DeDietrich Boiler has exceeded normal operating range?
If your DeDietrich Boiler displays 'Fan speed has exceeded normal operating range', it indicates a fan fault. Check the wiring and connectors for bad connections. Also, check for excessive chimney draught if the fan operates when it should not be. If necessary, replace the fan.
What to do if my DeDietrich INNOVENS PRO MCA 160 displays 'Deviation in flow sensor 1 and flow sensor 2 detected'?
If your DeDietrich Boiler shows 'Deviation in flow sensor 1 and flow sensor 2 detected', it indicates a flow temperature sensor deviation. Check the connection for bad connections and replace the sensor if it's faulty.
What to do if my DeDietrich INNOVENS PRO MCA 160 displays 'False flame detected before burner start'?
If your DeDietrich Boiler displays 'False flame detected before burner start', it indicates a false flame signal. The burner may remain very hot. Check the ionisation/ignition electrode, and if no flame should be present but O 2 Ionisation current is measured. If necessary, replace the faulty gas valve or ignition transformer.
What to do if my DeDietrich Boiler displays 'Safety parameters Level 5 are not correct or missing'?
If your DeDietrich Boiler shows 'Safety parameters Level 5 are not correct or missing', it means the safety parameters are not OK. Check the wiring and connectors for bad connections.
What to do if my DeDietrich INNOVENS PRO MCA 160 displays 'Comm Error'?
If your DeDietrich Boiler displays 'Comm Error', it indicates a communication error with the CU-GH PCB. Try restarting the boiler.
What to do if my DeDietrich Boiler displays 'Release Signal'?
If your DeDietrich Boiler displays 'Release Signal', it means the waiting time for the release signal has elapsed. You should remove any external causes, check the parameters for wrong settings, and inspect the connection for any issues.
What to do if my DeDietrich INNOVENS PRO MCA 160 displays 'Max THeat Ex'?
If your DeDietrich Boiler displays 'Max THeat Ex', it indicates that the maximum heat exchanger temperature has been exceeded. You should check the circulation (direction, pump, valves), water pressure, and ensure the sensors are operating correctly and properly fitted. Additionally, verify the cleanliness of the heat exchanger and that the installation has been correctly vented to remove air.
What to do if my DeDietrich Boiler displays 'Max Delta TH-TR'?
If your DeDietrich Boiler is showing 'Max Delta TH-TR', it means the maximum difference between the heat exchanger and return temperature has been exceeded. Check the circulation (direction, pump, valves) for no flow or insufficient flow. Also, check the water pressure, the cleanliness of the heat exchanger, and ensure the installation has been correctly vented to remove air. Finally, verify the sensors are operating correctly and properly fitted.
What to do if my DeDietrich INNOVENS PRO MCA 160 displays 'Max Delta TH-TF'?
If your DeDietrich Boiler is showing 'Max Delta TH-TF', it means the maximum difference between the heat exchanger and flow temperature has been exceeded. Check the circulation (direction, pump, valves) for no flow or insufficient flow. Also, check the water pressure, the cleanliness of the heat exchanger, and ensure the installation has been correctly vented to remove air. Finally, verify the sensors are operating correctly and properly fitted.
What to do if my DeDietrich Boiler displays 'Gas Pressure Switch'?
If your DeDietrich Boiler displays 'Gas Pressure Switch', it indicates that the gas pressure is too low. You should check the gas supply pressure, ensure the gas tap is properly open, and inspect the wiring. If these are not the issue, the gas valve may be faulty and need to be checked or replaced.
