Hi everyone I have a Potterton Suprima 60 system boiler with Cylinder. Lately on the Honeywell Smartfit thermostat it displays F04 and an orange light appears on the boiler. In consequence the boiler is now not heating the water. Every time this happens I switch off the boiler from the electric supply (switch next to boiler) and switch on again and the boiler works again. It is as if the boiler resets or reboots and then works fine for around 8 hours or so. Anyone had a similar fault? Or can anyone advise? I have checked the manual and it states check wiring from terminal block to PCB and if that is ok then replace PCB. In short the boiler just goes off and I have to switch off and on to fire it up again. I live in Forest Gate E7 (East London) please help!! Thanks hamzaldo
