**HEATING GURUS** Help!! Ferroli boiler issues

[arctic]

**HEATING GURUS** Swapped a wireless stat to a wired one due to connectivity issues the customer was having. The boiler is a ferroli domicompact f24d and the new Stat is a select thermsave, bog standard room stat. Now ever since the boiler is showing a F9 fault and producing no hot water, which the tech line tells me is a water heater sensor fault but very odd as only appeared when I swapped the stat??? Any ideas lads would be greatly appreciated!

Well personally i would listen to the tech line. Are you a spark or a plumber as i would not be fiddling around with anything beyond the main terminals of the boiler!

Well at a guess I'd say you've caused a bit of damage whilst you were Ferlinghetti around with the boiler. Probably just disturbed a connection somewhere..........hopefully, otherwise you could be paying for an expensive repair
