This problem is most likely being caused by air being trapped in the system. To fix this, please follow the following steps: -

- Turn on the Machine, ensuring there is water in the tank
- Wait until the light stops flashing and the machine is ready for use
- Lift the silver lever on top of the machine into the upright position
- Press the coffee button on your machine
- Push the silver lever back, away from you, and hold it in this position for 3 seconds
- Press the coffee button again to stop the water flow

This procedure releases the air blockage in the system and your machine should function normally again.

I just had the same problem with my new (less than one month use) Nespresso U. (the top of the capsule doesnt puncture and only water comes through). I called Nespresso customer service and a very helpful man suggested I run water through three times by pushing the top slider open with the Longa button pushed and then closed without a capsule in the chamber. That released the air bubble and now I am enjoying a wonderful cappuccino again! The customer service is fabulous, there was never a suggestion of charging me and I was told that Nespresso will send me a free loaner machine if anything goes wrong in the future that can be readily fixed over the phone. The Nespresso U is the best thing I ever bought.

Turn the machine off and unplug it from the wall for 10 seconds. It may just have a capsule stuck inside. Doing this will get the machine to eject any capsules when it is turned back on.

Lift up "the arm" and press the lungo button to at water, when you see water running through, press down "the arm", the water is now in the system again.

The switch is a very simple thing. I would take this apart and make sure the solder connection was not broken. If it was a quick soldering job will fix this. There is a very good likelihood that this has connectors rather than being soldered and they slipped off. If the switch is broken you will be able to find a replacement close enough to use at a home improvement store or hardware store.

Nespresso can advise you on switch replacement.
