Possible Causes
Partially blocked filters, Loose internal connector, Overheating motor, Failing thermal cut-out
How to Fix / Troubleshooting
Safety first: Unplug before inspection and allow the machine to cool.
- Clean filters: Remove and clean or replace pre‑motor and post‑motor filters to improve airflow.
- Check for blockages: Inspect hose, wand, and floorhead for obstructions that could cause overheating.
- Inspect cable strain relief: Gently flex the cable near the machine and plug (with the machine unplugged) to feel for breaks. Do not operate if you suspect internal cable damage.
- Service if unresolved: If cut‑outs continue with clear airflow, the motor or thermal cut‑out may be failing and should be replaced by a technician.
