I've had error code F61 twice, once on Tuesday & again this afternoon.
I know its something to do with the gas valve. On both occasions I just re-set the boiler by pressing the re-set button then fine (for a couple of days).
Trouble is, I've currently got no boiler cover (silly me).
I've got something similar but it's LPG, although all boilers in this range have the same error codes apparently. F.61 here means the gas valve control is defective.
