If your Dyson DC33 runs but the brush will not spin, carpet clean drops fast. The motor may sound strong. Air may move. Yet hair and dirt stay stuck in the rug. This is a very common DC33 issue.
The good news is this: most DC33 brush issues are not a motor fail. The brush stops on purpose when the vacuum feels stress. Once that stress is gone, the brush often spins again.
This guide shows the real reasons a Dyson DC33 brush will not spin and what to do step by step.
Why the Brush Matters on the DC33
The DC33 is a belt drive vacuum.
The brush:
Beats carpet fibers
Lifts hair
Frees deep dirt
If the brush does not spin, suction alone will not clean carpet well.
Most Common Cause: Hair Wrapped on the Brush
Hair wrap is the top cause.
Hair builds slow.
It wraps tight.
Drag builds.
When drag gets high, the brush stops.
How to Clean the Brush
Turn the vacuum off.
Unplug it.
Lay the vacuum flat.
Flip it over.
Cut hair along the brush groove with scissors.
Pull hair off in strips.
Spin the brush by hand.
It should turn with ease.
Hair Hidden in the Brush Ends
This is easy to miss.
Hair hides near the brush ends.
This adds drag you can not see.
On the DC33, the brush can be taken out.
Steps:
Remove the sole plate.
Lift the brush out.
Clean both ends well.
Put the brush back and test.
The Belt May Be Off or Worn
The DC33 uses a rubber belt.
If the belt slips, the brush will not spin.
Signs of belt trouble:
Brush does not move at all
Brush spins by hand with no drag
Burnt rubber smell
Check the belt when the brush is out.
If it looks loose, cracked, or thin, it needs swap.
Brush Control Set to Off
The DC33 has a brush on off control.
If set to bare floor, the brush will not spin.
Check the switch near the base.
Set it to carpet.
Test again.
Full Bin Can Stop the Brush
A full bin cuts air flow.
Low air flow makes heat.
Heat can stop the brush.
Empty the bin.
Clean dust from the bin seal.
Dirty Filter Can Shut the Brush Down
The DC33 has a wash filter.
When the filter is full of dust, air slows.
Heat builds.
The brush may stop even with no clog.
How to Clean the Filter
Remove the filter.
Rinse with cold water.
Squeeze and turn it.
No soap.
Let it dry a full day.
Put it back only when dry.
Clog in the Head or Hose
A clog can stop the brush.
Common spots:
Base of the hose
Neck near the brush
Under the sole plate
Remove each part.
Check for stuck dirt or toys.
Clear all paths.
Wheels Can Add Drag
Hair wraps on wheel axles.
This adds load to the head.
Spin each wheel by hand.
If it sticks, pull hair off.
Overheat Shut Off
If the vacuum ran hard, heat may stop the brush.
This can happen with:
Thick carpet
Long run time
Dirty filter
Turn the vacuum off.
Unplug it.
Wait thirty min.
Then try again.
When the Brush Still Will Not Spin
If you have:
Clean brush
New or good belt
Clean filter
No clogs
And the brush still will not spin, the head may be worn.
At that point, head swap or repair is the fix.
Quick Fix List
Clean hair from brush and ends
Check and swap belt
Set brush to carpet
Wash and dry filter
Clear head and hose
Let it cool
One of these steps fixes most DC33 brush issues.
Why This Is Common on the DC33
The DC33 is strong.
It pulls lots of hair.
That hair wraps fast.
Pet homes see this more than most.
The Bottom Line
If your Dyson DC33 brush is not spinning, it is most times not broken.
Hair wrap, belt wear, heat, or air loss stop the brush to keep parts safe.
Clear the drag.
Restore air flow.
In most homes, the brush spins again and carpet clean comes back right away.
