If you gind too fine, it will overload the pump and result in the "open tap" a few seconds into brew. Rinse and gind coarser to clear out malfunction.

I think you use too fine grist on the grinder, or the coffeebeans are really dark and moisty. Try to set the grinder to a coarser grist, for dark roasted coffee it`s not recomended to to use any finer than medium grist. However, the sieve in the brewing unit could be clogged, and you need to clean this out. Put a finger up in the brew unit just along the grounds blade, you will probably find a lot of old fine coffeeground up the. Clean it up as best as possible, and then try to make coffee with coarser grist. If this helps, it`s smart to run a cleaning program to be on the safe side.
If nothing of this helps, you don`t have a choice, you have to send it for service, then the brew unit has to be dissasembled and cleaned from the inside.

I had a similar problem. I took off the side and rear cover, followed the hose that comes from the steam wand to the rear of hte unit. It enters a solenoid made by ACL Italy. I dismantled the solenoid unit by disconnecting the two hose ends, removing the relay, and unscrewing the plunger unit (vertical pipe). The plunger unit internals should move freely up and down like a piston in a cylinder , powered by a small spring. In my unit, this plunger was calcified and seized. I soaked it in boiling water and pressed on it gently several times and it unstuck. I put it all back together again and presto! Good luck
