What to do if my DeDietrich MPX 28/33 MI COMPACT 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 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 28/33 MI COMPACT?
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.
