How to Fix / Troubleshooting
Safety first: Remove the battery before opening any housings or accessing switches.
- Check for debris: Inspect around the trigger or power button for dust, sticky residue, or pet hair. Clean gently with a dry cloth or compressed air.
- Try multiple presses: Press the button or trigger repeatedly to see if operation improves, indicating intermittent contact.
- Disassemble handle (if comfortable): Remove screws from the handle housing to access the switch and UI board. Look for loose connectors or corrosion. Reseat any ribbon cables firmly.
- Replace switch or UI board: If the switch feels loose, does not click, or shows signs of burning, replace the trigger switch or entire user interface board according to parts availability for your Bissell model.
- Professional service: If you are not comfortable opening the handle or if F2 persists after cleaning, seek service from an authorized technician.
