Hi, I’m Matt from eSpares. If your Dyson
DC07 has lost suction, it’s probably down to one of four things.
Now before you do anything, make sure you’re unplugged from the wall. First thing to check
are your filters; here’s the pre-motor filter, it’s
a washable filter, so if it’s looking dirty, give that a good wash. If I
just remove the bin/cyclone assembly, then I can get to the post-motor filter, which
is under this cap. Now that’s looking pretty manky, that’s
not washable and you will need to replace that with a fresh one.
If yours is a HEPA DC07, then the post-motor filter will look like this one; again, replace
it if it’s looking particularly bad. So next I’m going to check to see if we’ve
got any blockages; any coins or stones anywhere. If I remove
the valve pipe assembly, just check that, just see if you can see or feel anywhere where
there might be a problem. If I just flip it over as well, I
can check this u-bend; nope nothing in there. Now, the third thing to check are the hoses,
the main hose on the back, but also this internal hose here.
If you can feel any nicks or splits in there, then that will certainly lead to a loss of
suction. If that’s all OK, I guess the last thing
to check is going to be the motor. Now you’ll probably know if it’s a
problem with the motor because of the sound, but just have a little check around, check
the belt. Now the belt drives the brushroll, which doesn’t
directly affect suction, but if the brushroll isn’t turning then
it’s not going to operate very effectively. Now you can see me change most of those parts
in other eSpares videos, which are available on the
eSpares site or on the youtube channel. Thanks for watching.
