KRUPS xp7225 LEAKS FROM THE
For mine, the solution, which also applies to other similar Krups machines, was to replace the seal at the bottom of the boiler. (#MS-5015004). This seal was torn. While in there, I also replaced the piston (#MS-0697072), which seemed like a good idea, since its O-rings seal the top of the chamber. I got my parts from Nelson Appliance.
To replace the seal (from memory, so there might be some details missing or incorrect):
1. Remove drip tray, coffee drawer, water tank, and side bin
2. Remove top metal cover and one screw underneath that holds down the plastic insert
3. Remove the one screw that holds the cover inside the bean hopper and carefully pop off the grinder adjustment knob. The hopper should now come off.
4. Slide the front plate (gray/silver plastic) up until it pops off. Remove the four screws underneath it.
5. Remove the screws from the top of the unit (two at front, one in a recessed hole in the back).
6. Remove the two screws under the water tank.
7. Pry/pop the top off, and pry the side/back cover off.
8. Unplug the grinder from the circuit board, remove the two screws that hold it in place, and remove the grinder.
9. Remove the coffee line from the piston. Remove its clip and then remove the two screws underneath it.
10. At this point, you will need to disconnect most of the other wires from the circuit board or the components they go to, and you will need to unbolt the piston carrier, so that you can remove the frame that holds the grinder.
11. Remove the three screws that hold the boiler to the base.
12. Holding the shaft from underneath, remove the screw that holds the screen in the middle of the plunger in the boiler.
13. The plunger and shaft can now be removed.
14. The seal goes in the hole at the bottom of the boiler that the shaft runs through. I used a toothbrush handle to push the new one into place from the bottom. Make sure the lip of the new one is fully seated in the opening (look at it from the top of the boiler and work it into place while apply pressure from below). Once it's properly seated, there should be noticeable drag on the plunger shaft when it is moved inside the seal.
15. Reassembly is the reverse of removal.
