It is clear that there is a problem with water supply. Check if pump works, if it does, there is blockage in water supply to pump. Check and clean.

The unit has two pressure valves that control release to the drip tray. Once they fail the hot water will go directly to the drip tray when the pressure goes up. The fix will be to replace the pressure valves (pair in series) which only cost about $20. I replaced mine and it fixed the problem. Good luck and happy espressos.

Testimonial: "Thanks! Very helpful. Now we can (probably) solve a problem that will bring espresso back into our lives!"

The problem with the XP4050 is the two safety valves that the water goes trough on its way to the coffee head. They are plastic and some of the parts will just become brittle because of the hot water and the contamination they gather. With my XP4050 they just broke and parts of it were in the rubber tubes that go to the waste tank.They are also very cheaply constructed compared to the more robust parts of this machine. The water to the hot water/steam head does not have these valves and has a completely different routing. I am currently trying to fix the machine with just one valve and parts of the two valves that are still good. Fingers crossed....
