Troubleshooting My Philips AquaTrio vacuum cleaner's brushes do not work This can have several causes. Check all possible causes to do with your appliance in the following order. 1. The lid of the mopping nozzle is not closed properly Sometimes the lid appears to be properly closed, while in reality it is not. Make sure it is closed properly. 2. The Active Protection System has been activated When the Active Protection System has been activated, the brushes do not rotate and no water is applied to the floor. To reset the Active Protection System: Switch off the appliance and pull the plug out of the wall socket. Open the mopping nozzle lid, remove the mopping brush cover and take out the object. If the active protection system was activated because the mopping brushes are too wet, remove the mopping brushes and squeeze them over the sink. Place the dry mopping brushes back into the appliance. Replace the mopping brush cover and close the mopping nozzle lid. Press the mopping nozzle lid to lock it ('click').
