Krups XP4000 Pump Espresso Machine. It comes on and gets incredibly hot but no water ever comes through. It shakes a lot, makes a really loud noise when turned on. The tank is full and pushed in as far as it can go. The filter is empty because this is the first time I'm cleaning before use. I do not have a water filter in it as one didn't come with the package. I can't figure out if I'm doing something wrong or it's a defective unit. I bought at the holidays as a gift for my husband and we checked the items but didn't get a chance to try it out until this last weekend..but nothing will even come through on the initial cleaning so we haven't been able to even try the espresso. I'm going step by step on the instructions but can't figure this one out. Can you help? Krups XP4000 Pump Espresso Machine. It comes on and gets incredibly hot but no water ever comes through.

You can call KRUPs to see if there are any major differences.

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!"

SOURCE: No espresso coming out.

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....
