Possible Causes
Complete blockage in hose or wand, Motor exhausting hot air into confined area, High resistance electrical connection near handle, Partially melted hose lining
How to Fix / Troubleshooting
Safety first: Stop using the vacuum immediately and remove the battery. Allow the tool to cool before touching hot areas.
- 1. Check for blockages: Detach the hose and wand. Look through them against a light source. Clear any obstructions with a flexible rod.
- 2. Inspect hose interior: Look for signs of melting or collapse inside the hose. Replace if damaged.
- 3. Inspect handle area (if hot): Open the handle housing and check for discolored or melted wiring and connectors. High resistance joints can generate heat.
- 4. Repair wiring: Replace any burnt connectors or wires. Ensure all crimp and solder joints are solid.
- 5. Test under light load: After repairs, run the vacuum briefly and monitor temperature. If heating persists, have the unit serviced professionally.
