Dyson V7 Pulsing

Problems:

The vacuum pulsates and loses suction intermittently while in use.
The filter on top can be dirty, causing the vacuum to pulsate.
Debris may be stuck in the suction tunnel or roller area, affecting airflow and causing pulsation.

Solutions:

Dirty Filter Fix:

Remove the top filter and either replace it or wash it with water.
Let it dry for 24 hours before reattaching it.
This should resolve the pulsating issue if the filter was the problem.

Clogged Suction Tunnel Fix:

Check the suction tunnel and roller area for blockages.
Use tweezers or similar tools to remove any debris stuck inside.

If necessary, remove the vacuum roller.

Use a penny or coin to twist the roller compartment cover counterclockwise.
Pull out the roller, clean the area, and reassemble by twisting clockwise.
This will improve airflow and stop the pulsation.

Dyson V7 Flashing Blue Light (12 Times)

Problems:

If your Dyson V7 vacuum flashes blue light 12 times, it could indicate potential issues such as motor failure, electrical problems, or filter problems.

Tried Solutions:

While some sources speculated that the flashing light could indicate a motor problem, further testing has ruled out this possibility.
The filter was removed and cleaned, but this did not fix the issue.

Final Solution:

After trying various troubleshooting steps, it was determined that the battery was faulty. Replace your vacuum battery with a new Dyson V7 battery to successfully resolve this issue.
