How to fix a Krups XN2001 Nespresso machine

Click here to see some amazing Latte ArtMaybe the title of this post should read “how to open a Krups XN2001 Nespresso machine”. The Krups XN2001 is almost identical to the newer XN2002 and XN2003. While the XN2003 has normal Torx screws, Krups was a bit more “protective” when they built the XN2001. It has screws that can not be gripped by any screwdriver. Still, there is an easy trick you can use to get headless screws out of any machine.

My Krups XN2001 Nespresso maker has been working fine for the past few years. I descale it almost monthly with very cheap vinegar, but otherwise it needs no maintenance. Just after I repaired my free Aeroccino, the power button of the Krups XN2001 started to fail. It was hard to turn the machine on, like there was a bad contact.

When I tried to open the Krups XN2001, I noticed these funny looking screws, which looked more like nails. After I discovered that these were actually normal screws, I needed to figure out how to get to the ones at the bottom.

Yes, it's a screw, not a nail! No Dremel in the world could reach those...

I took the Nespresso machine to a hardware store I frequently visit, and talked to a new hire there. I showed him the machine and he took off on a rant about how I should not open it, that it was dangerous, and it would void the warranty. I told him it was a five year old machine and it was for fun. Just when he got irritated and told me “doesn’t matter, you can’t open it”, a colleague of him overheard our conversation. He looked at the new hire, smiled, and while pointing at me said “but he can”.

A few laughs and a short discussion later, it turned out that they did not have tools that would fit or grip the headless screws. I went into “MacGyver mode” and got an aluminum rod that fit nicely on top of the screw head without touching the plastics of the case, and grabbed a tube of industrial strength superglue.

At home, I cut the rod into a few shorter bushings, and used the lathe to make them nice and flat. I carved a slot on the other end of each bushing with a dremel tool. Then, I carefully superglued the bushings onto the screws without touching the plastic, and let them settle for a few minutes.

Super Glue and a bushing. Note the slot for the screwdriver. Removed screw with the bushing glued to it.

After the glue set, it was very easy to use a normal screwdriver to get the screws out. I took the screws with the glued bushings back to the hardware store to show them what I did and got me some new philips head screws with matching size.

Once you open it, you can see how simple this machine is. There’s not much that can break, and parts look like they can be easily replaced. Instead of just cleaning the contacts in the button, I decided to go a little further and replaced the existing ones. I had to cut away some placeholders for the old pushbuttons, and drill a hole to hold the green led which tells you what the machine is doing.

All the electronics. Not much to it, really. I also replaced the "dispense" button The repaired Aeroccino and the repaired Nespresso happily together.

As you can see my Krups XN2001 now looks a bit “steampunked” but it works like a charm!

      To hell with the manager who made that decision to use those diabolical oval-headed screws! I just wanted to share a very simple solution I was lucky enough to come up with.

      I have a small screwdriver set that includes the hexagonal M sockets. I figured that since the internal space of a hexagon was longer from corner to corner than it was from side to side I might have one that fitted. As it happened, the 3.5mm one fitted the oval, although not tightly enough for all the screws. My solution was to squash it slightly with a pair of pliers (a vice would have been better) and that worked perfectly.

    Nice. I just took a 6mm double screw [it is in fact a long screw-nut] shape its inside with Pliers and little hammer… in 10 min i had my D190 completely naked. thanks for the spirit!

  3. Bram says:

    Just looked at your Krups XN2001 repair. That’s exactly what I want to do. Lookes great. Removed allready the on/off switch and added a toggle switch. The other, temperature or warming up switch, I want to change as well with a toggle switch. I looked at your pictures. You have added a seperate light (green) to the housing. The three white wires from the little printed circuit board go to the swich (2) and one to the light. My question is where does that orange wire go to? Can you help?
    Look forward to your reply.

    • rolfje says:

      If you look carefully at the printed circuit board, you see that the LED and the switch share one connection. Because my LED is farther away, I needed an extra wire to connect the switch and the LED the same way as on the board.

      By the way I would not recommend toggle switches, they probably will not work. You’ll want to use push buttons.

      • Bram says:

        I installed a push button and a seperate LED light as per your instructions and the machine works again like a charm. I left the power on/off toggle swich in place. Is there any reason why you do not recommend a toggle switch? I bought two push buttons so I have one standing by, just in case. The whole operation costed me 2.80 Euro. Thanks for your wonderfull assistence.

      • rolfje says:

        I recommend a push button because the original button is also a push button, not a toggle switch.

  4. chris says:

    thank you! i hope you stil read this.. ive got machine apart at the moment. the power button was my first replacement. now my coffee one is acting up. I took it apart and the rubber button fell apart (making it useless now). So, im trying to replace the coffee button and there are three wires instead of two. how does the whole led thing work? Ive tried desoldering the ones i thought were the button wires and attaching a button like the other one (i dont care about the led at this point, id rather just have the coffee button working first). So, Ive got three wires. what do I with them?maybe unsolder the led one as well so as not to confuse the machine? i thought for certain the led wire was the one soldered directly onto a path leading to the bulb on the circuit. ugh, any advice would be great! my main goal is to have coffee again in the morning asap haha

  5. rolfje says:

    Same advice I gave bram: Look at the board. The first white wite goes to one end of the switch. The second white wire goes to the switch and the led (this is probably the ground wire), and the third white wire goes just to one end of the LED. Make pictures. Mark the LED, as it will not work if you connect it the other way around. Unsolder the marked wires and the marked LED. Drill a hole for the LED, and connect everything up exactly the same as it was on the circuit board. The LED and the switch should both work perfectly.

  6. chris says:

    Thank you for your response. I managed to mark and identify the wires last night. Now its working but without the LED (i just feel if its warm or not, then i know its on).
    So, the fourth wire is something you ran off of one part of the new button. And that’s just electronics wire, any particular strength? And sorry one more question, did you reuse the LED or buy a new one? Im trying to figure out how you separated the LED from the board. Thank you again!

    • rolfje says:

      It’s the original LED, with a soldering iron it’s easy to remove from the board. The orange wire is one that I had lying around, just a general electronics wire, no particular strength. An LED like this takes about 20mA, any wire will do really.

  7. Fred says:

    Thanks Mr R, the trick is indeed getting the thing open. Thought the were rivets or something! The screws came out easily with thin pliers. Machine is working again. If it stops again, I’ll replace the push buttons
    Thanks again

  8. larry says:

    HELP WITH TROUBLESHOOTING – After taking apart and cleaning and checking all electronic components, I still get the blinking lights 3 times. Then, I measure the following resistance with a multimeter – NTC = 93.5 k Ohms, T167 Fuse = 0.2 Ohms, Thermoblock = 44.9 Ohms, T 128 Fuse = 0.3 Ohms, Pump Motor = 311 k Ohms.
    Are these normal? Or is the Pump Motor burnt up? If not, I guess I need to buy a new electronic main board? Any ideas on where and how much it costs?
    Lost without expresso

    • rolfje says:

      Hi Larry, I only replaced the buttons, I never checked any other parts in the machine, so I don’t know if the things you are measuring are expected values. The pump motor feels like a high resistance but I don’t know what type of pump it is and if it should be like that.

      You say you get the blinking light 3 times. Is that after plugging in, or turning on? After blinking, does the light go out or stay on? Does the base of the machine get warm (it should)?

      • larry says:

        Thanks for the reply. As soon as I turn the switch to ‘on’ both lights flash 3 times pauses for a second, then flashes 3 more times and continues to repeat this cycle with no way of getting it to reset. Nothing turns on or heats up. According to the troubleshooting manual I was able to get my hands on this means a component failure and then gives you a list of what components to check and in what order – the only problem it does not tell you exactly how to check.

        Still lost without expresso

    • tomalamix says:

      The T128 e T167 Fuse must be near 0ohm (0 – 50 ohm).
      The Thermoblock is around 50ohm in two cases ive tested and both are working
      The NTC is 100Kohm at ambient temperature around 25º C. It will increase a lot as the temperature rises.
      The pump i didnt measure so i dont know if its ok or not, sorry.

    • Enzo says:

      Larry, if you want to fix your nespresso machine, replace the two blue “squared” capacitors on the board with others with the EXACTLY same values. Pay attention to use capacitor X2 type!
      I had the same problem and I fixed successfully.
      Look my directions on:

  9. chas R says:

    I used an aluminum spacer and vise grips to create an oval driver. A hacksaw blade across the opposite side allows the spacer to accept a flat head screw driver. I took the panels off and ran a cycle to find a source of the leak. Evidence pointed me to the water heater inlet hose and a blown rubber O ring. Couldn’t find the O ring locally so I used silicon gasket cement to “roll my own”. No more leaks. Thanks for hosting this column.

  10. Paul says:

    Great post. It helped me a lot to know that these strange metal points were actually just screws. I looked in my shed to find a small metal tube of the right size and hammered the end to an oval form. The screws are not tightened very strong, so no problem getting them out and in again.
    I had the same problem with a faulty on/off switch. I just cleaned the contact and it works again.

  11. Jorgen says:

    Thx for your discription on how to open the krups machine. I found you through Google. We experienced the same problem. I want to tell you That i opened the machine by using a pair of pointed pliers. Your blog was very usefull in this case. Many thanks again.


  12. Markus Heidt says:

    Graphite spray!
    When I first repaired a machine, I replaced the switsch as well.
    But then I got the hint to use graphite spray in the back of the silicon buttons. Remember not to spray into the LED button but use a stick or something else to cover it.
    Works like a charm.

  13. Jonathan says:

    The screws are called TORX for reference.

  14. Michael says:

    love your post. The screws are not called Torx. They are called Pan Head oval security screws. Very nice tutorial btw. I came across this because i need to take apart my Maestria d500 very soon

  15. Sasha Lutsky says:

    thank you for your manual.
    could you help me please to find the silicon button for nespresso essenza?
    i can not find it on the net…
    thank you.

  16. Claudio says:

    Hi all and thanks in advance for your help.

    I managed to fix the faulty power button by cleaning its back after opening the machine with a spare IKEA spacer screw 😀

    I still have a problem: when pressing the coffee button, the machine starts brewing coffee but then it tends to quit after less than a second and it powers off.
    I can power it back on so I can make coffee few drops at a time, but obvioulsy it’s not ideal.

    Sometimes, like once every 10 times, it can regularly make coffee, but certainly there is no way to make 2 coffees in a row.

    Extra info:
    – the machine has been descaled with no success in this issue;
    – if I press the coffee button more deeply, it switches off even earlier;
    – the coffee button has been cleaned in the same way as the power button (cotton stick with alcohol).

    I do not think that replacing the blue capacitors, as per Enzo’s recommendation, would help in this case as the machine gets ready indeed.
    Also, the fact that the machine powers off makes me think it’s not a mechanical issue – e.g. back of the button still dirty – or else it should not power off!

    Does that sound to you any pressure/temp sensor kicking in?

    • rolfje says:

      If it just quits maybe the brewing button makes contact again (second press stops brewing). But you say it powers down, which is quite different. Maybe the spacing on the power button became close after cleaning it, and the vibration of the machine causes it to make contact. A heat sensor can also be at fault, as you say you can not make two coffees in a row. What doesn’t add up is that if you press harder on the coffee button, it switches off earlier. That takes us back to that button again.

      Can you run it without the covers on, and take the two buttons out? If you can brew coffee without the rubber on te buttons, then the buttons are the problem. If not, I’d look for a faulty thermo sensor but I have no idea where that would be.

      • Claudio says:

        Thanks Rolfjie.

        Along other tests, I tried what you recommended here as well before you commented, but for some reason I could not add comments to… my comments if someone else hadn’t commented yet 🙂
        (Sorry for the repetitions!)

        I got to the conclusion that there were multiple concurrent reasons for the fault and it was time to replace the machine, after 5 years of excellent services.

        In the end I purchased a new one.

  17. Imad Jamil says:

    Hi All,

    I have the same Nespresso machine that stopped working since few days. I opened it and noticed that the little blue capacitor shown in one of the photos above is melted! Now i know that this is the issue, but the problem is that i don’t know the value of that capacitor 😦
    If you can tell me what’s the value written on the capacitor in your machine i will be able to fix mine 🙂

    Thank you in advance!

  18. Rolf says:

    Hi all,
    I just managed to replace the red button without removing any of the oval screws. How? Just remove the lever arm.. Then “split” the top of the machine by using a screwdriver. Both the side panels can easily be forced outwards with the base still fixed. The resulting access is sufficient to remove the next internal piece and subsequently to replace the button.
    Great succes!!

  19. Stef says:


    About the Claudio Wednesday 2014-05-07 problem:

    I encountered the same problem and here is my story:

    First I checked the functionality of the pump, connected it directly to the mains, it was OK
    Then I loosened the in and out of the heater and checked if the flow was not disturbed, caused by insufficient descaling. No apparent problem there. The temperature sensor also was working well as the blinking of the green led moved to steady green when the temperature level was met. Very hot indeed when touching accidentally by your finger!
    So what could be the reason of powering off when asking the machine to start the pump? The electronic module who did not succeed to swich the mains to the pump due to the amount of current it needs. Aging of one or more of the electronic components (capacitors maybe)?
    I decided to take another solution and did not touch to the electronics. I removed the green button and replaced it by a on-off switch to apply the mains directly to the pump. The green led was dismounted and placed through a small hole drilled in the front.

    That did the trick! I only have to wait until the green blinking stops, then I start the pump. Otherwise I get a brew which is cold or lukewarm.

    Hi from Melbourne Australia.

    Many thanks for this most informative blog.

    I had a case of ” the weird green flashing light ” the pump ran fir second or two, then stopped…… all I did was drill out the plastic around the recessed ” Copyright” screws, enough for me to grab the screw head with a needle nose pliers.

    It was a very small increase in the diameter of the original hole ,

    A Note : as the screws were installed in the factory with a compressed air gun, the torque setting is relatively low, so that makes it pretty easy to grab and SLOWLY twist the “copyright” screws. I naturally replaced them with Phillips heads.

    Then all I had to do was replace the 2 blue capacitors on the circuit board. 224K for the small one and 474K for the larger one. 275 Volt rated. Polarity didn’t matter…

    All worked great…

    Rafael, from Spain: I used the BIC trick for the bolts. Took some time, but it worked!! Thanks!!!

  22. Denis says:

    Thanks for the helpful and informative post. I am fortunate enough that my malfunctioning Krups Nespresso machine has the regular Torx screws, so no problem opening it for diagnostics.

    In my case, the tapered rubber ring in the machine base which should mate to the removable water reservoir spigot is not sealing properly, allowing water to seep out into the base of the machine, and then away to the outside world. Backing up the original ring with a thin rubber washer didn’t help, and it looks like running a bead of silicone won’t correct the problem either.

    Anybody have a clever solution to this problem? Thanks in advance.

  23. Willem says:

    Hi Rolf,

    I have a nespresso krups xn6006 and the machine won’t switch on. I would really like to fix it myself, but have close to no experience. Do you have any idea what the problem could be or where I could find more info? Google doesn’t give me any results (on my model).



    • rolfje says:

      A machine that does not start up can have all kinds of problems, I’d start with checking the fuse. The other components are hard to check visually, you’ll probably need a multimeter and a soldering iron. If you have close to no experience, be careful and please do not forget to disconnect the machine from the power when it is open, and only plug it in when you’ve closed it up again. Stay safe!

      • Willem says:

        Thanks for the quick reply. I ll only check the fuses then. I opened up the machine, but cant seem to get any further (more to the inside of the machine). No walktrough/guide available I guess on that type?


      • rolfje says:

        I didn’t find a repair guide for that type, but I suspect it should not be all that different from the XN2001. It is basically a heater, a timer, and a 2 bar membrane pump. It’s just the plastics that are different, for the largest part.

  24. Willem says:

    thanks a lot. I ll have a look into it.

  25. dadsan says:

    Hello from Northcentral Pennsylvania, USA. Lots of trees and mountains, few people. I have a Nespresso C91 that failed after trying too hard to force it to accept other brands of pods and refillable pods. The hard plastic pin that is the handle pivot and piston driver cracked and broke. Is there a way to find a replacement or a workaround, short of buying a whole new extraction module? (I took a picture but do not know how to put one in this comment.)

    • rolfje says:

      The Nespresso machines are not keen on accepting other pods. These generally break or deteriorate the seals and joints of your machine. I always advise against using aftermarket pods. After al, you did not buy a Nespresso machine to get Senseo coffee now did you?

      As for the pivot: In the XN 2001 I think the pivot are 2 screws left and write of the aluminum handle. I don’t know the C91, but if it’s really a pin, maybe you could get away with replacing it with a threaded rod of the right size.

      • dadsan says:

        Thank you. I think I have a solution. My C91 is also labelled Essenza. The handle attaches to the pin through slots, with screws for security. I think I can fabricate a steel rod with grooves sawed in to drive the protrusions on the piston shaft, and file the ends to take the handle. I have a metalworker friend. Or just glue a smooth or threaded rod in place. That will let me see if my misbehavior damaged anything else. The machine was excessed by my son, and I am only planning to use it as backup to my lovingly-restored old Olympia Maximatic, which is working very well and makes an espresso as close to perfect as I could taste. The Nespresso Kazaar comes close!

  26. Stefan says:

    Hi, thanks for your blog. Without you I would have given up. These screws did not even look like screws, more like rivets.

    Now my machine works like new.

  27. John says:

    Hi, thanks for all your help! I repaired my on/off button by cleaning it but now my machine doesnt heat, could you tell what is the main cause?

  28. John says:

    It’s working now, thanks for your fast answer! just one more thing, this is my first nespresso machine and when i tried to take a coffee, there’s some water running into the capsules compartment filling that little deposit below the cup’s place. If i take 2-3 coffees i have to empty it. I think it is some water that ,during the process, cant go through the capsule and comes back. A friend said to me it was normal and a known issue. It’s true? Because i think the coffees are getting to “light”. Thanks again for your answer!

    • rolfje says:

      It is normal to have a little water in that compartment but it should be from opening the lid just after making coffee. If the compartment is full after 2 or 3 coffees, you probably have a leak. Check the plunger edges, the capsule “piercer” edges. If you have it open, carefully try to make coffee to see where it leaks. Be careful, I normally don’t recommend running an opened machine, especially with water that’s dangerous. Hope you find it, stay safe!

  29. Daan says:

    Hi Rolfje,
    I’ve an nespresso le cube, when switched on nothing happens. Opened up the bugger nothing strange to see. Even in line fuses look normal on sight. Any clou what can be the problem?

    Thanks Daan

    How to fix a Krups XN2001 Nespresso machine | Rolfje’s blog

  34. Mario says:

    Hi, I have a Nespresso Essenza looks exactly like yours. Bought an oval screwdriver from Ebay, tick. Took it apart as for weeks I had irregular blinking from the silicone buttons and in the end the machine does not start at all.
    Interior is super clean, no leaks, I tested the power pre and post switch, all good. And then the blue and brown cables go to thermal sensors screwed to the heater part (looks like big piece of aluminum). Past those sensors there is no power which I would possibly understand as the thing is not heating. But when I started the machine -when it worked normally- the buttons would light up and blink until this unit heats up at which point the blinking would stop. Right now I have no clue why this is not happening and how the buttons are supposed to get any power at all as it seems the main power has to go through this unit anyway.

    Right now the all thing feels dead: it does not make the slightest difference if it’s plugged in or not, switched on or not!

    Any advice greatly appreciated!

  35. Bonhomme says:

    First, its Dangerous to measure on the Electronics, because the machine has a non-isolated power supply. ( Its a simple Capacitive impedance liniter ( the 470nF 250V ) feeding a Zener diode for about 15V across the filtering electrochimic capacitor ).


    Thats why replacing the original rubber buttons by other Buttons is my opinion a serious Electric Safety Issue, the new buttons can ingest Water ( they arent waterproof ) and you may Die from a Eletric shock by touching it.

    Thats also why this machine is protected from opening with the special ovale screws, because its really dangerous to investigate failures when the machine need to be under electric power.

  36. Plouc68000 says:

    watch this repair kit also: ( it contains the tools to open and the replacement Capacitor )

  37. Pete says:

    Rolfe, which button is adequate to replace the existing on/off one?

    how many amps, volts, ac, single pole, double pole….?

    Most ones I see (this this example: have three prongs, the third one, I presume, for an earth connection, witch the XN2003 doesn’t have on the small on/off board. Does that just get ignored?

    Which button characteristics should I be looking for?

    Thanks for a useful post… of many years ago!!!

    • rolfje says:

      Hi Pete, I used a single action momentary push button from a junk box. The switch should be normally open, and closed only when pushing it. Voltage and amps I don’t know, but it’s not directly connected to the mains if I remember correctly, so a low voltage pushbutton would do. Two prongs, no click.

  38. koh says:

    Thank you very much for this post. My machine can’t be power-on and there is no Led lit.. if anyone can offer some advice on what might the faulty component to replace on the circuit board ?

  39. Susana says:

    9 years after you posted this I’m fixing the same coffee maker but I’m having trouble with my led. Bought some nice buttons a a super duper led but, when the machine is off it lights up and when it’s on it turns off after the preheating blink. I’m at a loss her, have any idea?
