My Philips Barista Brew Espresso Machine is making noisel̥

It is important that the water tank is filled with water and placed properly into the machine. If not well inserted, it can draw air which will cause a loud pump sound. To make sure it is placed correctly, push the tank as far as possible and make sure the rubber cap is removed.
 

It is normal for the machine to make a ticking or hissing sound during heating up, or after brewing. What you hear is the internal heater warming up and the electronic valve operating to release the internal pressure, where steam and water will end up in the drip tray.
