Let’s dive into the most frequent causes and their remedies.
Common Causes of a Non-Spinning Motorhead and Their Solutions
Blocked Brush Roll or Gear Mechanism
Hair, threads, or small objects often wrap around the brush roll or gear, preventing rotation. To fix this:
1. Turn off and unplug the vacuum.
2. Remove the brush roll cover and inspect for debris.
3. Use scissors to cut tangled items and a brush to clear particles.
4. Check the gear mechanism at the motorhead’s end for obstructions and clear them with a screwdriver or tweezers.
5. Reassemble and test the brush bar.
Worn-Out Brush Roll
Frayed bristles or damaged brush rolls reduce effectiveness. Replace the brush roll every 6-12 months, depending on usage. Purchase a Dyson-branded or compatible third-party part, and follow the manufacturer’s installation instructions.
Faulty Motor or Electrical Connections
If the motor hums but the brush bar doesn’t spin, inspect:
– Electrical Contacts: Clean dirty or corroded contacts with a cotton swab dipped in rubbing alcohol.
– Internal Wiring: Check for frayed wires and replace if necessary.
– Motor Function: If the motor fails to power the brush bar, contact Dyson support for repair options.
Partial Airway Blockage
A pulsating vacuum or sudden shutdowns may indicate a clogged airway. Remove the dust bin and clean the bin inlet’s flap. Use compressed air or a wooden skewer to clear debris from the brush head.
Step-by-Step Troubleshooting for Motorhead Issues
Detailed Cleaning Process
- Disassemble the Head: Unplug the vacuum and detach the motorhead.
- Clean Electrical Contacts: Locate the metal contacts on the head and vacuum body. Wipe them with a soft cloth or alcohol-dipped cotton swab.
- Inspect the Gear and Brush Bar: Remove the brush bar, then clear hair or debris from the gear mechanism. Manually spin the gear to ensure smooth movement.
- Check Internal Cavities: Use a screwdriver to press the white tab and remove the dust filter. Clear hair and debris from the internal cavity using a T8 Torx screw.
- Reassemble and Test: Reinstall all components and test the brush bar’s rotation.

Frequently Asked Questions (FAQ)
How do I clean the electrical contacts on my Dyson V7 motorhead?
Turn off the vacuum, detach the head, and locate the metal contacts. Gently wipe them with a cotton swab soaked in rubbing alcohol. Ensure they’re dry before reassembly.
Why does my brush bar spin briefly then stop?
This often signals worn internal wiring or a clogged gear mechanism. Inspect wiring for fraying and clear debris from the gear.
