If there is no leaks, I would try to get some hot water from the wand.
If there is still no water coming out, I would:
1-Decalcify thoroughly
2-Open the machine and take the inside out and verify the status of the water pipes going from the water tank to the boiler than to the wand and the brew unit ... to make sure there is no restriction.
