Dyson DC07 overheating question

    Apologies for yet another Dyson query. The most relevant previous postings
    appear to have been pruned from the server.

    I thought I had fixed this by cleaning the pre-motor filter, but the cut-out
    has started again after 10 mins use. Certainly the area around the motor and
    base of the bin is very warm after 10 minutes use. Curiously the brush-bar
    still rotates at speed. I am not convinced the suction is as good as it was
    when new.

    1. Is there a Dyson self-help website that may be able to help me here ? Of
    course I could take this to a repair shop but I'd prefer to investigate
    myself first.
    2. Is there a maintenence/repair doc available for DC07 models ?

    Any thoughts on possible culprits here would be appreciated. Thanks Paul

    Don't know the Dyson inside out, but been in industrial vacuums for 25
    years!

    I would guess that your Dyson has a directly cooled motor, that is the
    air being moved to provide the suction also provides the cooling for
    the motor. Any blockage or restriction downstream of the motor will
    cause overheating.

    Any blockage or restriction upstream will affect the downstream and do
    the same, so look very carefully at filters, bends, hose joiners etc
    both in and out. Also check the fan blade it'self. If it's cracked or
    damaged it won't be moving enough air to cool the motor.

    Again guessing, is the brush bar driven by the same motor as the fan?
    If so, the motor is having to work harder, sounds like a damaged fan
    blade.
    Overloads are a warning. They weaken every time they trip.

    It sounds like there's a blockage in the airway somewhere.
    Have you checked inside all the removable bits of pipework?

    Thanks for your suggestions. I've just removed the removable pipework but
    there
    doesn't appear to be a blockage. It appears that after just a couple of
    minutes,
    the area where the motor housing meets the bin gets hot and hot air is being
    emitted, which is why it is cutting out.
    Could there be dust inside the motor housing ? Does anyone have some
    disassembly instructions ?
