combi condensing boiler LPG no heating no hot water when boiler runs water in boiler can be heard circulating as if air in system boiler shuts down and wont start up again shows F1 fault on screen

get your boiler serviced ,especially to clean the condendense trap ,white under the boiler it;ll be blocked .causing your bubbling noise and the f1 fault .lpg is a dirty gas and must be service every 12 months or it will cost alot more if it turns to a rock formation inside the boiler .
