What to do if my DeDietrich MPX 20/24 MI COMPACT Boiler has incorrect power supply frequency?
If your DeDietrich Boiler displays an incorrect power supply frequency, check whether the issue originates outside the boiler. If so, contact the power supply company.
What to do if my DeDietrich Boiler ignition fails after 5 attempts?
If your DeDietrich Boiler fails to ignite after 5 attempts, check if the gas valve is open and that there is no air in the gas supply circuit. Verify the gas supply pressure and ensure the wire is uninterrupted, making good contact with the flame sensing electrode and the ignition switch. Check correct operation of the condensate drainage.
What causes a DeDietrich MPX 20/24 MI COMPACT Boiler to lose flame at ignition?
A loss of flame at ignition in your DeDietrich Boiler may be due to the flame sensing electrode being in poor condition or incorrectly positioned. Check the wire to ensure it is uninterrupted and makes good contact with the flame sensing electrode and the ignition switch. Also, check for any recirculation of fumes.
What to do if the safety thermostat tripped on my DeDietrich MPX 20/24 MI COMPACT Boiler?
If the safety thermostat on your DeDietrich Boiler tripped due to overtemperature (likely caused by a blocked pump or air in the heating circuit), check the pump operation and the pump power input wiring. Also, check that the limit thermostat is undamaged and replace it if necessary, and verify the continuity of the limit thermostat wiring.
What to do if my DeDietrich MPX 20/24 MI COMPACT shows a gas valve control error?
If your DeDietrich Boiler shows a gas valve control error, check the connections between the gas valve and the electronic board. If necessary, replace the electronic board.
What causes a DeDietrich Boiler gas valve to be blocked?
A blocked gas valve in your DeDietrich Boiler may be due to an issue with the gas supply pressure or the integrity and position of the sensing and ignition electrodes and their wiring. If necessary, replace the electronic board.
How to troubleshoot a communication problem between the boiler board and control unit in a DeDietrich MPX 20/24 MI COMPACT?
To troubleshoot a communication problem between the boiler board and control unit, check the wiring between the Ambient Unit and the electronic board or RF link.
How do I calibrate the electronic board on my DeDietrich Boiler?
To calibrate the electronic board on your DeDietrich Boiler, activate the automatic calibration function described in the spare parts instructions sheet.
What does it mean if my DeDietrich Boiler has an internal board error?
If your DeDietrich Boiler indicates an internal board error, replace the electronic board.
What to do if my DeDietrich MPX 20/24 MI COMPACT shows a gas valve connection error?
If your DeDietrich Boiler shows a gas valve connection error, check the connections between the gas valve and the electronic board.
