Re: Europiccola

Hi there, you should screw the nut all the way down and then screw the second nut down to meet. These are only there to stop piston coming out when under pressure. The piston shaft is designed so that it will not go down far enough to push the shower plate out so you don't have to worry about this. I am domestic coffee machine engineer and we are leading UK service and repair agents for La Pavoni. Any problems please get in touch with David at

Use (2). And you could back it off by 1/4 turn, rather than 1/2 turn I think. You want the piston to almost touch the screen at the bottom of its travel. You don't want the piston to push the screen out.

Hello You Coffee machine friends. I have a problem that I don't seem to find the solution.I just replaced the two large O rings and cleaned the complete machine.I left the machine in the resting position...

I've done a couple of these and it can be tricky to get the lower piston the correct height when reassembling it. Did you make sure that the entire brew group would fully cycle (the white gear travels from to to bottom) without binding before reinstalling it? It seems to me that the piston has to mesh with the gears in JUST the right configuration so that it will come to the top of its travel without biding on the housing or being to low in the chamber when it goes through the ejection phase (dumping the grounds). I don't have a fool proof method to do this other than trial and error. I'd go back and take apart the group again and make sure the lower piston is aligned correctly and that it doesn't bind when you screw the gear all the way up and down. Good luck!!!

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.

Espresso comes out of comes out of spout before handle is raised

Hi there, i am Mr La Pavoni and am based in Glasgow, Scotland. I service and repair these machines all day every day and basically it could be a couple of different things. If it is pre 2000 then it could either be the piston gaskets or the piston shaft has come slightly unscrewed from the piston head. If it is post 2000 then it could be any of the above but also in these models there is an additional sleeve inside the group head which may be cracked or the seal on this part may need replacing. It could even just be a tiny bit of debris on one of the piston gaskets. If you have removed the shower plate and gasket and then taken out the piston assembley then you should really replace these gaskets anyway. You can purchase the parts on my website which are all individually priced and every part is available for the lever machines. If you require any further assistance then please do not hesitate to get in touch at

All the best

There is water leakage on my La Pavoni Europiccola machine

Hi there,
I am a domestic coffee machine engineer based in Glasgow, Scotland and i service, repair and refurbish these machines on a daily basis. You will probably find that the gaskets which are holding the sightglass in place are completely solid and resemble a hard plastic like gasket. There will definately be gaskets there as if not the sightglass would rattle about and the water would pour straight out. It depends on which sight glass nuts you have but if they are the clear plastic nuts you will find either black, white or clear gaskets underneath and if the nuts are metal then you should see brass washers first and then the gaskets underneath the washers. These are easily replaced and can be purchased from our website I hope this helps and if you have any further questions or queries then please do not hesitate to get in touch at

On a La Pavoni europicola which way do the piston seals get installed, both the same way or opposite to each other?

Normally on lever machines the top seal sits with the cup area(slash in gasket) facing up and the bottom facing down.

Adding pressure gauge to Pavoni Europiccola

  1. in the boiler water is heated and presured up to 1.5 bar
  2. when water gets in lever and non return valve closes becouse you press the lever down, your energy is used to get high pressure, it should be frpm 7 up to 9 bar.
  3. SOLUTION==if you search way for modifying, you must consider that you must pump directly to group, not to boiler. in this case water will be cold (becouse comes from pump). you will need boiler in boiler to heat the water wich comes from pump before it gets to group. this is bit more complicated than you thought may bee but it is only solution.
