Potterton Suprima 50L

Yes, I know, get a new one . Fires up (only using HW at mo), runs, burner on say 10-15mins then cuts out (flashing red), hold red, yellow flash once after 3 secs flashes again, after reset will work again sometimes until demand time complete. Think this indicates an ignition fault but if that's the case why when cuts out during burning!! New type pcb fitted 2009 thermistor 2014, Flushed last week with chemicals and new inhibitor as thought that might be the fault, any ideas welcome.

You need an engineer to have a look to be honest. Could be a few things. Dependant on what board you have. I know you said 09 for the board but doesn’t mean much

Even then. It can be more than 1 thing. Needs testing properly by a qualified engineer mate.
