How to troubleshoot a Saunier Duval Themaclassic F30E SB with no display on the control panel?
If there is no display on the control panel of your Saunier Duval Boiler, check the 230V supply, the PCB fuse, and the connection between the PCBs.
What to check if the fan does not start on my Saunier Duval Themaclassic F30E SB Boiler?
If the fan on your Saunier Duval Boiler doesn't start, check the continuity of the fan harness.
What to do when the fan runs but there are no sparks in my Saunier Duval Themaclassic F30E SB Boiler?
If the fan runs but there are no sparks in your Saunier Duval Boiler, check the continuity of the ignition components (electrodes and leads) and verify the power supply from the PCB to the ignition unit.
What to do if my Saunier Duval Themaclassic F30E SB Boiler burner doesn't light with a spark?
If the burner on your Saunier Duval Boiler doesn't light despite an ignition spark, first, ensure the gas taps are turned on. If the issue continues, inspect the wiring. If problems persist, consider replacing the control board (PCB). Also, test the gas control valve.
Why is my Saunier Duval Themaclassic F30E SB Boiler not giving hot water or heating with a red flashing light?
If your Saunier Duval Boiler (F30E/F35E models) isn't providing domestic hot water or central heating, and you see a red flashing warning light with a fault code, check for loose connections on the control board (PCB) and the air pressure switch (both electrical connections and tubes). Also, check the water pressure. Other potential causes include a shortage of air or gas, a faulty temperature sensor, or overheating. Inspect the control or interface boards (PCBs) as well.
How to fix a Saunier Duval Themaclassic F30E SB when the burner lights then goes out (F1 or F4 error)?
If your Saunier Duval Boiler's burner lights and then goes out (F1 or F4 fault), turn off the power and check the continuity between the flame sense electrode and terminal H2.4 on the control board (PCB). Inspect the connector on the wire's end and ensure the spark electrode is correctly positioned towards the flame. Check the spark electrode and consider replacing it. If the issue remains, the control board (PCB) may be faulty and need replacement.
What causes a Saunier Duval Boiler to light then go out with no flame detected (F1 error)?
If your Saunier Duval Boiler burner lights but then goes out, and no flame is detected (F1 fault), try cleaning the gas filter and the burner.
How to increase room temperature with a Saunier Duval Boiler when radiators are luke-warm?
If the room temperature is inadequate and the radiators are only luke-warm when using your Saunier Duval Boiler, increase the temperature settings.
Why is the water luke-warm at the taps with my Saunier Duval Boiler?
If the water at the taps is only luke-warm when using your Saunier Duval Boiler, verify that the 3-way valve isn't allowing water to pass into the radiators (the radiators should remain cold in Summer mode).
