Dyson V10 / V11 Pulsing & Filter Light Error: Filter Part (#969082-01)
Quick Answer: When a Dyson V10, V11, or V15 vacuum pulses (revs on and off 3 times) or flashes the Filter / Blockage light even after washing the filter, the internal HEPA Filter (#969082-01 / #970013-02) is saturated with microscopic drywall/carpet dust or the Trigger Switch (#V11-Trigger) has cracked.
⚠️ Why Washing Your Dyson Filter Stops Working After 1 Year: Microscopic plaster and fine dust bond inside the pleated HEPA paper of filter #969082-01. Even when washed clean on the outside, air cannot pass through the paper core, causing the motor to pulse and shut off!
#1 Most Common Fix: Dyson V10 / V11 Rear HEPA Filter Unit
Official OEM Part Number: #969082-01
⏱️ Install Time: 10 Seconds (Twist-on rear cap) | 💰 Avg Cost: $14.99 – $22.00
Step 1: Free 2-Minute Reset & Test
- Twist off the purple rear filter unit and try pulling the trigger for 2 seconds WITH THE FILTER OFF: if the vacuum runs smoothly without pulsing, your filter (#969082-01 or #970013-02) is 100% the culprit!
- If the trigger feels mushy and doesn't click or activate the motor at all, the internal plastic red trigger lever has snapped.

Frequently Asked Questions
How do I know for sure if my Dyson needs a new filter?
Unscrew the purple filter from the back of the vacuum and press the trigger briefly. If the pulsing stops immediately and suction is strong, replace the filter (#969082-01 for V10 or #970013-02 for V11/V15).
