Dyson DC31 repair
Dyson DC31 Brush Roll Repair
The brush bar in the powered cleaner head fitted to this machine should be checked for a physical jam, end-cap seating, and free movement before a drive failure is considered. Only DC31 Motorhead packages receive powered-brush diagnostics; the base DC31 uses non-powered direct-fit tools. This procedure is scoped to the DC31 (DC31) and its cordless Dyson handheld platform.
This guide remains available for safe identification and inspection, but we do not offer a repair or Dyson parts CTA for the DC31. The next supported path is choosing a current replacement vacuum.

Instructions
How to complete this repair
- Bright flashlight
- Scissors or a seam ripper for wrapped fibers
- Soft dry brush
- Clean lint-free cloth
- Power the handheld off, disconnect its charger, and remove a detachable battery only when the exact owner guide describes that action.
- Use only owner-access points and maintenance actions documented for the exact machine code.
- Do not cut toward the brush surface, wiring, soft roller, or cleaner-head housing.
- Do not open a brush motor, gearbox, powered-head wiring channel, or sealed bearing housing.
Confirm the DC31 configuration
DC31 (DC31) is a bagless handheld body with direct-fit cleaning tools. Cataloged variants include DC31, DC31 Motorhead. The verified owner-service profile identifies it as the Dyson DC31 retired handheld family. Match the machine code and serial label before ordering a filter, bin, direct-fit tool, battery where owner-replaceable, or charger; a retail family name can cover incompatible hardware.
Remove the correct brush assembly
Follow the exact owner guide to detach the powered cleaner head fitted to this machine and access its removable brush bar. Only DC31 Motorhead packages receive powered-brush diagnostics; the base DC31 uses non-powered direct-fit tools. Detach the floor tool or cleaner head from the machine before working around the brush.
Clear the brush and accessible ends
Cut and lift away hair, thread, and fibers in small sections. Remove debris from accessible end-cap and inlet areas without prying off a sealed bearing or gear cover. Check for melted fibers, cracks, distortion, or an end that remains seized.
Check the platform-specific connection
Confirm the powered cleaner head fitted to this machine is seated in the correct orientation, its end cap is locked, and the surrounding airway is clear. Do not add a belt step: the catalog does not list a user belt repair for this machine.
Make one controlled brush test
Reassemble the machine completely and test the powered cleaner head fitted to this machine briefly on a clear, suitable surface. Stop if it stalls again, pulses, smells hot, shows an error, or makes a grinding noise.
A brush that remains stationary after debris and external connections are checked needs professional cleaner-head, drive, or control diagnosis.
