Hi all
Wonder if anyone can help me, i have spent the last couple of hours wrestling with a 105he...here is the tale. I got asked to go look at the boiler and when i got there the boiler standby light was on, when i called for heat the correct calling light came on then after 10 secs a fault light came on saying pump problem(when calling the lights came on bot nothing operated in the boiler). Tested the pump whiched was goosed so changed that, called for heat, fan started, pump ran but no ignition. Tested the fan and had 240v when running and correct resistance when off so i hurridly came to the conclusion its the APS. Changed it, still no joy. Took the fan apart, and cleaned out the venturi and air blasted the main flue, still no joy. I then took the black tube (Black and clear tubes connecting APS to fan) and boiler fired up...hey presto! Re connected the black tube and back to square one.
Got me a bit confused, anyone had this before???
