Model compatibility has not been independently verified
Earlier archive data contained suggested model or series names. Without a clear model/code table in a manufacturer manual, these names are no longer displayed as verified matches.
This is general brand/device guidance; check the model label and official manual.
Open manufacturer sourceWhat does it mean?
The manufacturer identifies F61 as “Gas valve control circuit fault” for the covered boiler models. Code meanings can differ by model, region and platform; this is not proof that a specific part has failed.
Model match: No manufacturer-manual confirmed exact model list is available for this record. Check the model label and official manual.

What a technician would check
An authorised gas technician verifies flame sensing, inlet gas pressure, ignition chain, flue/condensate path and safety interlocks.
How to verify the result
After a successful user-level check, normal operation should resume and the code should not return. If it repeats, a qualified technician should inspect the exact model.
Do not dismantle sealed systems, gas valves or electrical control boards. Warranty conditions vary by country and model.
