The coffee brews fine but the steam wand is not working. I just cleaned it and water comes through the wand in a good stream and it steamed. A couple of hours after cleaning, the steam wand has stopped steaming again.
When I got my X1 (used,) the steamer was clogged. I unscrewed the end of the nozzle, and a big chunk of calcium(?) came out. I had to poke it with some wire with the steamer on. The way I got the end off is: I wrapped it with a leather glove first, then turned it with a pair of pliers. I still managed to scratch it a little bit though. Maybe you can turn it by inserting a needle in the little hole on the side of the nozzle. I've been thinking of using distilled water to avoid the calcium build-up in the future.

Does the pump come on (do you hear it?) but no water comes out when you make coffee?
When you select Hot Water and open the steam valve, does the pump run and does water come out the steam valve?
If you hear the pump running but no water is coming out - then it could either be that the pump needs to be primed. In that case you would select Hot Water and open the steam valve all the way and let water run out the wand for a minute or two.
If the steam wand delivers water but you don't get any water when you brew coffee, then either the coffee is ground so fine that the water cannot go through the coffee grinds OR the filter disc may be plugged up. Try grinding coarser and try removing the filter disc and cleaning it with a toothbrush - hold the disc to the light and verify that you can see through all the tiny holes.
If it pumps water for coffee but you don't get water out the steam pipe, then the steam wand may be plugged with hardened milk - in that case remove the plastic frother and soak it and clean it. Also use a bent paperclip to clean the hole in the end of the chrome steam pipe.
If the pump doesn't run at all and you don't hear any pump noises ever - then either the pump has failed or has a loose wire.
Check the end of the steam wand and the parnello it may be blocked use a paper clip to clear, as for the brew unit the shower screen may be blocked it will have to be removed and cleaned. It is located under the red o-ring, then adjust the grind coarser. If that solves the problem for the coffee, but the steam wand solution does not work then it is clogged higher on the line in the system.
Sounds like the boiler is blocked, and machine needs to be descaled. Try this first remove the parnello if your machine has one on the steam wand then using a paperclip clear out the end of the wand, that might be blocked. If it isn't then run the descale to clear out the blockage in the boiler.
Check the connection to the boiler from the pump, there is no water going to the boiler. Try this test, remove the brew unit you will see a white plastic valve behind it, carefully lift the small lever on the valve(HOT WATER), if water sprays, then the problen is at the brew unit, if no water then the boiler inlet or outlet is clogged.
Several things I would check here. How old is your machine? Is the coffee coming out hot enough? If not, then perhaps the boiler is not reaching optimum working temperatures and needs replacing. When did you last descale your unit? If you live somewhere where there is a lot of hard water, and you don't prefilter it, then it could be scale build up in the tube. Try soaking only the tube end of the wand in some vinegar for about an hour, then try flushing it with steam once again. Finally, one has to be dilligent in CLEANING the steam spout right after you use it, EACH AND EVERY TIME! (that is why you almost always see barristas with a damp cloth over their shoulder, ready to use). Milk left on the wand will bake on and become quite hard to remove. This will happen on the outside as well as inside the tube. Soak the end of the tube with boiling hot water for about 10 minutes, wipe the end clean, and with a fine wire or pin clean the inside of the steam wand tube. You may have to repeat this procedure several times to fully clean the wand. If you are at all mechcanical, you could take your machine apart, remove the wand, and soak/clean it separately. But only do this if you are a quite confident handy person. Hope this helps and good luck!
security valve of boiler openes to early and dont let the pump to rise pressure enough for good brewing( if it is this you can see water returning back to container if you have 2nd pipe in your machines reservoir)
