The DC28’s brush roller problem typically traces back to mechanical obstructions, electrical faults, or component wear. Hair and debris accumulation is the most frequent culprit, but issues like a broken belt, clogged filters, or a malfunctioning motor can also disrupt operation. By systematically addressing each potential cause, you can resolve the issue without costly repairs. Below, we explore common causes, detailed troubleshooting steps, and maintenance tips to keep your DC28 running smoothly.
Common Causes of DC28 Brush Roller Malfunctions
The DC28’s brush roller may fail due to:
– Debris: Hair, string, or dirt trapped around the roller or internal connectors.
– Worn or Broken Belt: The belt connecting the motor to the brush roller can stretch or snap.
– Faulty Motor/Air Muscle: Reduced power delivery to the brush head.
– Clogged Filters or Hose: Restricted airflow increases resistance.
– Loose Wiring: Disconnected or damaged electrical connections.
– Control Board Issues: Malfunctioning PCB or misaligned sensors.
– Battery Weakness (Cordless Models): Inadequate power to drive the brush roller.
Troubleshooting the DC28 Brush Roller: Step-by-Step Solutions
1. Removing Debris from the Brush Roller
Hair and debris are the primary reasons for brush roller failure.
– Steps:
1. Unplug the vacuum and lay it on its side.
2. Inspect the roller for hair or string.
3. Cut debris with scissors, avoiding damage to bristles.
4. Check the black spiral connector inside the roller housing for blockages.
2. Replacing a Worn Belt
A stretched or broken belt prevents the motor from spinning the roller.
– Steps:
1. Remove the bottom cover and examine the belt.
2. Slide the old belt off the motor shaft and roller.
3. Fit a new belt, ensuring proper tension and alignment.
4. Reattach the cover securely.
3. Addressing Motor or Air Muscle Faults
If the brush roller still doesn’t spin after clearing debris and replacing the belt:
– Steps:
1. Disassemble the brush head to access the motor/gear area.
2. Clean obstructions from the drive mechanism.
3. Replace the entire brush assembly (model DY91750601) if the motor is faulty.
4. Cleaning Filters and Hose
Clogged filters or a blocked hose reduce suction and strain the brush roller.
– Steps:
1. Remove and wash filters under running water; dry completely.
2. Disconnect the hose and clear blockages with a wire or brush.
If your filters are damaged or excessively worn, replacing them can significantly improve your vacuum’s performance and reduce strain on the brush roller motor.

– Steps:
1. Open the bottom cover and check wires for damage.
2. Re-seat connectors on the control board.
3. Use a voltage meter to test power delivery to the head.
Advanced Repairs and Maintenance
Removing the Black Spindle for Deep Cleaning
Persistent issues may require disassembling the black spindle:
– Use pliers to extract the spindle.
– Clean built-up hair behind it and reassemble.
Resetting the Beater Bar Mechanism
For models like the DC41 (and similar DC28 variants):
– Toggle the on/off button five times while holding the power button to reset the system.
Routine Maintenance Tips
- Empty the dust container regularly to prevent clogs.
- Lubricate moving parts (wheels, roller bearings) every 6 months.
- Replace filters every 6-12 months to maintain airflow.
Frequently Asked Questions (FAQ)
Why does my DC28 brush roller stop after a few seconds?
This often occurs due to excessive resistance from debris or a faulty air muscle. Clean the roller and check the motor’s power output.
Can a clogged filter cause brush roller issues?
Yes. Restricted airflow increases strain on the brush roller, triggering shutdowns. Clean or replace filters to resolve this.
How do I test if the battery is the problem?
If the brush roller spins briefly but stops, check the battery’s charge. If fully charged, replace the battery if the issue persists.
What part replaces a faulty brush assembly?
The DY91750601 brush assembly is the recommended replacement for motorized brush head failures.
Conclusion
A non-spinning Dyson DC28 brush roller is a fixable issue when approached methodically. Start with simple solutions like debris removal and belt replacement before moving to advanced repairs. Regular maintenance, such as filter cleaning and lubrication, prevents future problems. If troubleshooting fails, replacing the brush assembly (DY91750601) or consulting a professional may be necessary. By following these steps, you can extend your vacuum’s lifespan and maintain optimal performance.
