Troubleshooting My Philips AquaTrio does not flush on the flushing tray If this happens, the brushes have become too wet and activated the Active Protection system, which needs to be reset. 1. You poured too much water into the flushing tray Do not pour more than 300ml into the flushing tray. 2. You poured the water into the flushing tray too quickly Pour the water slowly into the flushing tray and make sure that the water level does not exceed the MAX indication. If the above solutions did not solve your problem, please contact Philips Consumer Care in your country.
