Frequently Asked Questions - Semia Condens F24 E SAUNIER DUVAL
What does the error code 'F24' mean on my Saunier Duval Semia Condens F24 E?
Error code F24 indicates a flame detection failure. This can be caused by a faulty ignition electrode, ionisation probe, or gas supply issues. Reset the boiler by pressing the reset button; if it persists, contact a qualified technician.
How do I adjust the heating temperature on this boiler?
To adjust the heating temperature, turn the heating temperature dial (usually marked with a radiator symbol) to your desired setting, typically between 30°C and 80°C. The digital display will show the set temperature.
Why is my boiler losing pressure? How do I repressurise it?
Boiler pressure can drop due to leaks or after bleeding radiators. To repressurise, locate the filling loop (usually a flexible hose with valves), open both valves slowly until the pressure gauge reads 1.0–1.5 bar, then close the valves. If pressure drops frequently, check for leaks.
What maintenance does the Semia Condens F24 E require?
Annual servicing by a Gas Safe registered engineer is recommended. This includes cleaning the heat exchanger, checking the burner, verifying flue gas analysis, and inspecting electrical connections. The user can check system pressure and reset the boiler if needed.
How do I reset my boiler after a fault?
Press and hold the reset button (often a black button on the control panel) for 2–3 seconds until the display resets. If the fault reoccurs, note the error code and consult the manual or a technician.
Can I use the boiler if the expansion vessel pressure is low?
No, low expansion vessel pressure can cause frequent pressure drops and may lead to system damage. The pre-charge pressure should be 1.0 bar. Recharge using a bicycle pump at the Schrader valve on the vessel; if unsure, contact a professional.
What is the warranty period for this boiler?
Saunier Duval typically offers a 2-year manufacturer warranty for parts and labour, extendable up to 10 years with an annual service by an approved engineer. Check your documentation or retailer for details.
Why is my hot water not getting hot enough?
Possible causes: the DHW temperature is set too low (adjust the DHW dial), a faulty diverter valve, or scale buildup in the heat exchanger. Try turning the DHW dial to a higher setting (max 60°C). If problem persists, need professional descaling.
How do I bleed a radiator with this boiler?
Turn off the heating and wait for radiators to cool. Use a radiator key to open the bleed valve on the top of the radiator until air escapes and water starts to drip. Close the valve and check the boiler pressure; repressurise if below 1.0 bar.
Where can I download the user manual for the Semia Condens F24 E?
