Possible Causes
Broken accessory detection switch or Hall sensor in handle, Damaged wiring in extension tube, Dirty or bent accessory contacts, Faulty accessory detection circuit on main PCB
How to Fix / Troubleshooting
Safety first: Turn OFF the vacuum before connecting or disconnecting accessories.
- Step 1 – Inspect mechanical latches: Ensure the extension tube and nozzle click firmly into place. A loose connection can prevent detection.
- Step 2 – Clean contacts: Wipe the electrical contacts on the handle, tube, and nozzle with a dry cloth.
- Step 3 – Test handheld only: Run the vacuum in handheld mode without the tube. If it works, the issue is likely in the tube or nozzle.
- Step 4 – Try another accessory: If available, attach a different Philips accessory. If it is detected correctly, replace the faulty tube or nozzle.
- Step 5 – If no accessories are detected: The detection switch or Hall sensor in the handle, or the main PCB, may be defective. This typically requires professional diagnosis and replacement.
