Dyson V6, V7 V8 Vacuum Pulsing (On / Off) – 100% Guaranteed Fix
If your Dyson cordless vacuum keeps pulsing, surging, or turning on and off repeatedly, don’t panic — this is one of the most common issues with the Dyson V6, V7 and V8 models. This step-by-step guide from VacRevive Australia shows you exactly how to troubleshoot and permanently fix the problem.
🔧 Step 1 – Check for Blockages
Most pulsing issues come from airflow restrictions. Remove each component and make sure nothing is blocking suction:
- Dustbin & Cyclone Connector : Empty the bin and clear any trapped debris.
- Wand & Head : Detach the wand and look through it under light to ensure it’s clear.
- Cleaner Head : Remove the roller brush for a full clean. If yours is worn or seized, consider replacing it with a genuine part like the Dyson V7–V15 Anti-Tangle Torque Drive Head .
Optional Parts for Cleaning and Replacement
🧽 Step 2 – Clean or Replace the Filters
Dirty filters cause reduced airflow, which makes the motor pulse to protect itself. Remove both the pre-filter and the post-HEPA filter, wash them with cold water, and let them dry completely (24 hours minimum). If they still smell or look stained, replace them:
⚙️ Step 3 – Inspect the Battery & Motor
If the vacuum still pulses after clearing blockages and cleaning filters, the issue may be power delivery. Weak batteries or faulty motor sensors can cause intermittent cut-outs.

🔩 Step 4 – Check the Bin Runner and Seals
Loose or damaged bin runners / sealing rings allow air leaks that trigger pulsing. Inspect the latch and rubber seals; replace if worn:
- Genuine Dyson Bin Runner (V10 & V11)
- Replacement Dust Bin Lid Cap for V7 & V8
- Dust Bin Sealing Ring Replacement
💡 Step 5 – Test Your Dyson
Re-assemble your vacuum and test it. If the motor now runs smoothly without stopping, congratulations — you’ve fixed the pulsing issue! If not, the internal motor assembly may need replacement; we can help.
