When you press the coffee button the machine grinds the beans, but then the water comes out the steam wand... please help

The problem is a very frequent one a small scale part have been moved and it stack to the water steam valve and it blocking it from closing completely. So when you make coffee the hose of water for coffee is in parallel with hot water steam wand and since the valve remains partially opened the water for coffee find easy escape from steam wand.

So we suggest to perform one more descale and it may need twice hopefully this small scale part to be dissolve a little bit more in order to pass thought the steam valve and thus the valve can close again completely. If you are not so lucky the part remain on the valve then only solution is to disassemble the machine thus clean the steam valve manually. In this solution you may find out that the valve o ring might be damage and thus the leak.
here is the link with steam valve parts and this the parts diagram of the machine and here many more for your machine

Hello

Unplug the machine and remove the coffee container by loosening its two fastening screws. Pull up on the adjustment lever and turn the grinding adjustment ring until its two blue marks line up, which will let you remove the ring. Vacuum or brush out the machine's gear box and grind-ring support, and reassemble the machine.

Use a thin needle to check the steam/hot water spout hole for clogs. Steam and hot water will not be dispensed properly when the hole is clogged.

Adjust grinder levels if there's a problem with the speed of the coffee dispensation. Move the level lower if coffee is dispensed too quickly, and move it higher if coffee is dispensed too slowly.

Descale the machine by pouring a descaling solution into the water tank (the solution package will specify the amount), selecting the automatic descaling mode and placing a large container under the water spout. Allow the machine to descale, which takes about 45 minutes, and remove and rinse the water tank with fresh water. Then, fill the water tank with water and allow the machine to automatically rinse itself.

If none of these steps corrects the problem, contact a professional for repairs.
