Hi, I'm Josh from eSpares.
If you're experiencing a loss of suction with your Dyson DC33 vacuum cleaner there's going
to be one of five reasons as to why this might arise.
Safety first- before you carry out any work on it, make sure you've unplugged your machine
from the mains.
The first place that you're going to experience a loss of suction from is with the filters.
This Dyson along with all other Dyson models has two filters in it.
A pre-motor and a post- motor filter.
The filters are designed to trap dust and harmful particles and to stop them from getting
into the machine and causing problems with the internal workings of it such as with the
motor.
But obviously if you get too much of a build up of that dirt and dust it's going to cause
a real problem with suction in your machine.
So the first place we're going to look is the pre-motor filter.
To remove the pre-motor filter from the machine, press this catch here and lift the housing
out of the vacuum.
The pre-motor filter comes with two parts: a sponge and the case.
These can be washed under cold water and with the sponge make sure you give it a good ringing
out to remove any excess moisture.
The case similarly can be washed under cold water and then just give it a good tap to
dislodge any trapped dirt and dust.
It's really important to make sure those are bone dry before you replace them back in your
machine.
While they are designed to be washed, if after cleaning them they're still dirty it's probably
a better idea to just replace them altogether.
The next place we're going to look is with the post-motor filter.
The post-motor filter in most bagless vacuum models is housed either near to or underneath
the canister.
To access it on the DC33 flick the catch here and lift the lid.
The post-motor filter is an all-in-one unit and as with the pre-motor filter can be cleaned
in pretty much exactly the same way.
Just clean it under some cold water and then give it a good tap to dislodge any trapped
dirt.
Again, make sure it's completely dry before you put it back in the machine and also if
it's still dirty afterwards it's probably better to replace it altogether.
Once you've cleaned the filters on your DC33 and you've still got a loss of suction the
next place to check is with the hose.
The hoses on most bagless vacuums are designed to be removed for cleaning or for altogether
replacement.
To remove it from this DC33 press the catch at the top here which lifts the wand away
and turn it round, pressing this button on the back which separates the wand from the
hose.
Finally press this button down here and this allows us to lift the hose away from the vacuum.
Here we have what is obviously an extreme example but make sure you're checking along
the hose for any splits or tears because these are going to cause a real problem with loss
of suction in your machine.
Once you've got the hose from your DC33 have a good feel along it for any large blockages
and also be checking the material for any splits or tears.
Obviously if you do find anything like that you're going to need to replace it with a
new one.
Once you've checked the main hose, turn the vacuum onto it's front and have a look at
the internal hose underneath here.
Same as before, look for any large blockages that you can see and also for any splits or
tears in the material.
Once you've checked the hoses you can have a look at the ducting.
Here we have the u-bend, have a look for any blockages in there and this piece here, similarly
have a look for any blockages.
Once you've got the pieces of ducting off, don't be afraid to have a feel inside for
any blockages that might be trapped in the airways.
Once you've checked the hoses and the ducting you can move onto the belt.
The belt, while not causing a strict loss of suction, is designed to turn the brush
roll so if it's broken the brushroll won't turn and it won't pick up anything off the
carpet which will create the impression of a loss of suction.
So obviously if you've got a broken belt, it's a good idea to replace it.
Finally, once you've checked the belt, the filters, the hoses and the ducting and you've
still got a loss of suction- it's more than likely that the problem will be with the motor.
In which case you're just going to need to replace it with a new one.
You can see me replacing parts on this DC33 in other eSpares videos.
Thanks for watching.
