Diagnosing the DC35 Motorhead Issue
The motorhead’s failure to spin often stems from mechanical obstructions, electrical faults, or power delivery problems. Begin by identifying the exact cause through systematic checks:
Check the Black Spiral Connector
The black spiral connector inside the motorhead is a common culprit.
1. Remove the brush roller and inspect the connector.
2. Ensure it spins freely without the roller in place.
If it’s stiff or immobile, hair and debris buildup behind the spindle might be the cause. Use a cotton swab or small tool to clear obstructions. Even if the connector appears functional, hidden hair accumulation could still disrupt its operation.
Clean the Brush Roller and Internal Components
Hair and debris often jam the brush roller, causing mechanical resistance.
1. Disassemble the brush head completely.
2. Remove hair from the roller and inspect internal components for wear or plastic fragments.
3. Clean thoroughly, ensuring no debris remains in the hub or housing.
A clogged roller can mimic electrical failures, so meticulous cleaning is essential.
Assess Battery Power Delivery
A weak battery may fail to supply adequate power to the motorhead.
1. Test if the brush head makes a spinning noise when it stops.
2. If the motorhead is silent, the battery might not deliver sufficient voltage.
Charge the vacuum fully and retest. Persistent power issues may indicate a failing battery or wiring problem.
If the battery is not holding a charge or is quickly draining, it may be time for a replacement. This will ensure the motorhead receives adequate power.

Inspect for Loose Wires
Electrical connectivity issues can cause intermittent spinning.
1. Open the motorhead and examine internal wiring.
2. Look for loose, frayed, or disconnected wires.
Secure any loose connections or replace damaged wires. A faulty wire may cause the brush head to stop and restart unpredictably.
Advanced Troubleshooting: Disassembly and Repair
For persistent issues, a deeper inspection is necessary. Follow these steps to address hidden obstructions or mechanical failures:
Tools Required
- Coin (to unlock the brush tube)
- Philips screwdriver
- Small Torx screwdriver (CR-VT7)
- Round-nose pliers
- Cotton swabs and rubbing alcohol
Step-by-Step Disassembly
- Remove the Spinning Brush Tube: Use a coin to unlock the side cap and slide the tube out.
- Detach the Front Bar: Unscrew the two Philips screws securing the front bar.
- Extract the Cog: Remove the Torx screw in the cog’s center (hold the cog steady with a pen), then pull it out with pliers.
- Clean Debris: Use a cotton swab to clear hair from the cog’s hub and brush bar. For stubborn buildup, apply rubbing alcohol.
- Reassemble: Reinsert the cog, secure it with the Torx screw, reattach the brush bar, and close the side cap.
Test the vacuum post-reassembly to confirm the brush spins freely.
When to Replace the Motorhead
If cleaning and repairs fail, replacing the motorhead may be the only solution. Users report mixed success with Dyson’s customer service, so purchasing a replacement from retailers like eBay is often faster. Ensure compatibility with the DC35 model before buying.
Additional Common Issues and Solutions
| Issue | Cause | Solution |
