My combi boiler has broken down, After lighting the pilot the system fires up and hot water is produced for about 5 minutes max, then it cuts out. As soon as the central heating is switched on the boiler cuts out. How can I mend it, does anyone have up-to-date, clear instructions I could follow, the manual we have is too complicated to follow. Please help, have been recently made redundant and cannot afford call out fees.
my porterton 80e is constantly on even though i'm not calling for heat or hotwater
