Will try to keep this simple: spring last year oil got low in tank I tipped it up to get dregs out & it finally ran out just as the weather had warmed up (didn't bother topping up through summer - used immersion). In doing this I had let the water sitting at the bottom of tank into the oil feed line.
When restarting around 6 weeks ago no chance ! Now after changing 2 * pressure relief valves, a expansion vessel oil pump & one nozzle , it worked for a day & packed in .
If you crack off the return from pump to tigerloop, there is oil pumping out - however there is none if you disconnect the oil supply pipe to nozzle from pump. This I explained this to the OFTEC reg boiler eng who had changed the pump initially, he tried turning pump shaft, found it stiff & said I had still water in line & this is what had knackered new pump - it's a Riello RDB burner by the way.
Can this be right ? the pump works but it seems to me that the solenoid valve is not opening - I've tried a current detector pen on the current supply to the solenoid and at no stage does it light up (although pen advises a min of 50v, it does however respond to my 18 v drill battery & I believe the supply to solenoid is stepped down to twentysomething volts) with this being the case I'm suspecting the control unit at fault ?
Often on this site the advice is get a pro around - this I have done, but I am not entirely confident in his evaluation (he was a awkward so & so as well but that's beside the point !)
TBH, I'm tempted to just cut my losses & purchase a full new burner (£200) - it's now snowing outside & wife & 3 young kids are freezing, at least then I know nothing is broken.
UNLESS someone can describe a easy way of testing out solenoid valve or can it be frigged to be left open.
Hope someone can help because this has been doing my nut in for 6 weeks now- good money after bad.
