There are several things that can cause this. The most common is a clogged coffee basket; on this machine the basket can be disassembled for cleaning, do so and hold the metal screen up to a light to check for clogs. If the basket is clear, it's possible that your coffee is ground too fine, you're putting too much coffee in the basket or you're tamping too hard. It's also possible that the brew head screen has becomed clogged; you can remove this with a phillips head screwdriver and inspect it as you did the coffee basket screen. If you've done all of this and the issue persists then you probably having a failing pump; very common in this model as well as most other Delonghi semi-automatics.
