Hi. A newbie here. Have good DIY skills but central heating kinda goes over my head??
My Trianco is 10 years old. Has run faultlessly all this time until recently.
All of a sudden we have no hot water. Boiler stone cold and has not appeared to run. Press the button (lit orange) on the relay box and bingo, she fires (fan runs fine). I can then here it going out then relighting in random pattern. No air bubbles in the oil feed and plenty in the tank.
This happened couple of weeks ago and he above sequence cured it and it has ran no issues until now.
Stats working fine. It gets to stat temp and cuts out. Wind the stat up and it fires. Worth mentioning that at this point the orange light on the relay box is NOT lit.
Any ideas. I've looked for diagrams to strip it (not afraid of stripping it down if I know what I'm looking for).
I'm thinking partially blocked jet or something similar????
Any suggestions greatly appreciated. Thanks
