Hi Wim,
              Sounds like the hammer rail has been installed in the wrong 
position. (Rotated towards the back of the action)  Screw a few balance 
rail punching's under the rear action bracket feet, to diagnose.
If the piano is under warranty, get them to fix it.   Fudging the hammer 
line/ dip is one possible solution.  Shimming the rear feet.  And or a 
little of both.  But it is still a cheater  fix.
Regards Roger
