English
Meaning
The main fan motor of the air purifier has a critical fault. The motor cannot start or operates abnormally. The purifier stops delivering air, and air purification is completely lost.
Common Causes
- Motor bearing worn or seized, rotor unable to turn
- Motor windings shorted or open — coil burned out
- Power component on the motor driver board (IGBT/TRIAC) failed short
- Internal thermal fuse on the motor blown
- Foreign object (dust clumps, insects) sucked into the motor intake jamming the fan blades
Self-Check Steps
- Power off the purifier and unplug the power cord, wait 1 minute, then power on again
- Listen closely for a humming sound from the motor without blade rotation — this suggests a drive circuit issue
- Check the intake grille for large debris blockages
- Clean heavy dust accumulation on the pre-filter and rear intake grille
- ERR P typically requires professional service — contact Dyson to replace the fan motor assembly
