Hi
Hoping maybe sombody can help with this. Scoured quite a few forums, but this fault code (F0) never seems to be mentioned!
The boiler works normally most of the time with no problems.
However, when the boiler fires first thing in the morning on the timer, it will lock out with error code F0 and flash the reset button. The text display says 'F0 internal error'. Pushing and holding the flashing red reset button for a few seconds restarts the boiler.
The Bosch engineers booklet is not very helpful. It says to check all connections, and if that fails replace the PCB.
The PCB has now been substituted out (with two others!) yet the fault persists.
Don't really know what to try next. Transformer? Ignition leads? Help!
Thanks for any help.
Dave
