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 F27 as “False flame / ionisation signal” 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.
