When asking for hot water the combi fires up but after around 5-10 seconds the lockout led illuminates.The same happens when the central heating is switchd on.
Any of you Bright sparks outthere put me in the right direction of what to look for?

hi, do you have a pressure gauge on boiler? if so it needs to show abt 1.5 bar, if much less needs topping up,
Other easy check is to listen for fan running at start up, no fan=no go.
