Possible Causes

Overheated motor driver MOSFETs on main PCB, Blocked cooling vents around motor housing, Clogged pre‑motor filter causing high load, Failing motor bearings increasing current draw

How to Fix / Troubleshooting

Safety: Remove the battery pack and allow the unit to cool for at least 30 minutes before inspection.

  • Cool down: If the vacuum has been used continuously on high power, let it rest until the housing feels cool to the touch, then retry.
  • Clean air paths: Remove and clean the pre‑motor and HEPA filters. Ensure the motor air intake vents on the Parkside housing are free of lint and dust.
  • Check for restricted airflow: Inspect the extension tube and floor head for partial blockages that can overload the motor.
  • Inspect motor sound: With a clean airflow path, run the vacuum briefly. If you hear grinding or high‑pitched squealing, the motor bearings may be failing and causing overheating.
  • PCB inspection (advanced): If comfortable, open the motor housing (after removing battery) and visually inspect the main control PCB for burnt components or discoloration near the motor driver area. If damage is visible, replace the PCB module.
