Riello 40 noisy

Fakediamond

Hi there,

I ran out of oil and got a fill today. Burner wouldn't start so I got out the Allen keys and turned a few screws to get the oil running, without really knowing what I was doing. Anyway, after reading some threads on Boards, I reset the thermostat and hey presto, I have heat again!

My problem is that the burner now seems to be noisy and rumbling on ignition and I'm wondering have I over or under tightened a screw while trying to get it going?

Probably will need a call out to fix it, but post some pics of anything you adjusted to see if we can spot something

Thanks for reply, I can't face dismantling it again right now, as its outdoors, dark and freezing! I really only turned the Allen screw on the front, to the left of the ignition button. Some oil dripped out so I screwed it back in. Could I have over tightened it?

In your post you stated “a few screws”, but if it was only the one you described above, it’s unlikely that that caused your problem.

Well ok, I did have a go at another one around the left side, but don't think I had much of an impact on it, as it was hard to reach. It just sounds kind of explosively noisy when starting now, and was fine before today. It's due a service anyway, just don't want it to blow up before I get that organised!

Are you sure it was an Allen screw that you were opening? Not a bolt or screw?

Fakediamond

Honestly? It was freezing cold and dark and I was tinkering about trying to get the oil flowing as I thought that was the problem. I might have slightly turned a nut just under the Allen screw, but I don't think so? I only had an adjustable spanner and couldn't get a proper grip on anything.

You can’t loosen an Allen head with an adjustable spanner. You need to get it looked at.

the easiest to fiddle with is the pressure adjuster

I had another look and the nut underneath was loose and dripping oil when burner ignited. I've tightened that up and the situation has improved. I need some decent spanners though.

Thanks for your input folks. I will get it serviced asap.

As Jim says. If you turned any screw with a screwdriver, it is likely that you have changed the oil pressure. Raising it could cause the boiler to be noisy, and it could soot up. Look out for smoke. If you had to reset the thermostat, it may not have been that you were out of oil.

The problem was the pressure adjuster and a plumber has just fixed it for me.

I was lucky to get someone to come at this busy time, I won't be doing that again!
