Morning guys
I installed a new Grant 26e external combi just after Christmas. The oil supply was on a temporary supply from an ivt tank which was new and clean. Cross land filter as per installation as always!
after around 2-3 weeks the burner locked out and on inspection it was humming with no motor sound when pressing the lockout button. Press again and it fires up. All settings spot on 11.5 co2 pump pressure 8 bar.
it runs ok for say a day then bang, lockout. Same noise then press again 10 min or so later and off it goes.
so called Grant they send a sub contractor out after the problem occurred every day for weeks and he says the oil pump if gone due to oil contamination. On inspection of the pump filter it was full of black crud so fair enough. My filters are clean!!!! So after my angry customer who incidentally wanted the temp oil supply because of building works and new tank later has had a go at Grant they decide to pay for a pump but he had pay the engineer 75 quid which he did.
All was fine for two hours then lockout again! Customer resets and away we go again. Next day bang, lockout again!
this time I ring Grant up and said I will double check the oil supply for water and the filters and all was good.
i reset the burner checked the set up again and it's been ok up until last week when lockout again.
So Grant this time send their own engineer who whips off the pump and says the filter on the pump has a bit of black crud in and is seized up. Customer takes the pump and turns freely so says how can that be seized, engineers says it's screwed so sticks another new pump on, checks oil for water and all other filters fine! Two hours later whoosh, lockout again man!!!!
customer has reset again this weekend and will be on the phone to Grant tomorrow.
So all you very experienced engineers out there could you possibly shed some of your opinions if you have any short of changing the burner out?
cheers
