Dyson V15 Post-Filter HEPA
The most common cause of pulsing is a saturated filter. Even if it looks clean, microscopic dust particles (e.g., drywall dust or talcum) can clog the HEPA membrane, restricting airflow and triggering the motor's safety cutoff to prevent overheating.

Main Body and Cyclone Assembly
If pulsing persists with the filter removed, the V15 is prone to motor control board failure. Specifically, degraded capacitors fail to stabilize current to the motor windings, causing a voltage ripple that triggers the safety cutoff. Dyson does not sell the PCB separately; the entire main body/cyclone assembly is the required service part.

High Torque XL Cleaner Head (Brush Bar)
Debris lodged in the neck of the cleaner head or a tangled brush roll creates mechanical resistance. This resistance forces the motor to draw excess current, which the V15 detects as a fault, resulting in the pulsing sound to alert the user to a blockage.
