Possible Causes
How to Fix / Troubleshooting
Safety: Switch OFF the vacuum and remove the battery pack from the handle or main body.
Cool down:
- Allow the battery to cool at room temperature for at least 30–60 minutes away from direct sunlight or heat sources.
- Do not place the battery in a fridge or freezer; rapid temperature changes can damage cells.
Inspect vents and contacts:
- Check the cooling slots around the battery compartment on the Gorenje cordless vacuum. Remove dust with a soft brush or compressed air.
- Inspect the battery contacts and the mating contacts on the vacuum for corrosion or burnt marks. Wipe gently with a dry cloth.
Test again: Reinstall the cooled battery and try running the vacuum on low power first. If it runs normally, the error was likely thermal protection.
If E3 recurs quickly: The battery pack may be failing internally or drawing excessive current due to a motor fault. Stop using the vacuum and contact service for battery pack testing or replacement.
