    Hi, I have a 5 year old Heatslave 2 combi oil boiler which was recently serviced.

    I have just notices a strange noise coming from it... the heating is fine, and there are no error messages.

    Is there anything to be concerned about?

    Just a random guess from me, but it sounds like the burner fan is either catching something or is loose on the motor spindle.

    Thanks John, is that dangerous? Should I keep the heating off until I can get someone out to have a look?

    It’s not likely to fail catastrophically but for sure it isn’t right.....if it’s what I think!
    If you can hold on until the more experienced oil guys come along?

    Definitely sounds like a motor bearing problem.

    It could be the burner fan catching or in an extreme case which is unlikely
    it could be the fuel pump, take the panels off while it’s running and try to find where the noise is coming from. Bob

    Listening to it again on a laptop I’d say knackered motor bearings allowing the fan to drift.

    To me it sounds like a Typical RDB bearing howl.

    Probably 6202's I think.....I prefer the ZZ's to RS types.

    Thanks Everyone... I took the front off. Sounds like its coming from this motor (the burner?)




    I had it serviced a couple of weeks ago, the green tube is new, after I was recommended I 'upgrade' from what was there.

    Thanks

    Yep, that’s your Riello burner - the green pipe is a long life oil feed which has a significantly longer safe running life than the original braided one.
