  1. Nespresso CitiZ Teardown, Nespresso CitiZ Teardown: passo 1, imagem 1 %32
    • The CitiZ is a compact coffee-making gizmo. Opening it requires a proprietary tool that Nespresso doesn't sell.

    • You can get into it with a pair of needle-nose pliers. The pliers I used aren't ideal — you want something that can get into the recessed slots.

    Try a 3 mm socket - it worked on my machine.

    The tool is a socket or box spanner with an oval hole opening; they are available from amazon. I have two types: one is a 1inch long tube with hexagon head for using in a removable bit screwdriver handle, the other is an L-shaped tubular tool with the opening at each end.

    The 2018 and above version of the Pro tech toolkit comes with an appropriate bit for exactly these screws. You can also buy the bit separately.

    8in crescent wrench used end on worked really well for the oval head screws

    David Carpenter - Responder

    Seeing the recommendation, I heated the end of the BIC pen with a lighter and while hot pressed it against the oval screw, let cool then applied pressure and turned gently, the procedure for each screw worked.

    • Now that the screws are removed, use a screwdriver or a spudger to pry the tabs holding the bottom case on.

    • The easiest place to get in is the power plug. Be careful not to nick it. (And make sure you're unplugged from the wall!)

  4. Nespresso CitiZ Teardown: passo 4, imagem 1 %32
    • Carefully open the lower case and set the machine on its side.

    In the picture background there is a box of a Nespresso Inissia, however the machine actually being handled (KRUPS XN7006) is a CitiZ machine.

    • The plastic strain relief bracket on the power cable is challenging to remove. Insert a small flathead screwdriver into the small slot on one side to disengage the tab.

  6. Nespresso CitiZ Teardown: passo 6, imagem 1 %32
    • Nespresso makes heavy use of spade connectors inside this machine.

    • Grab one side firmly with your pliers and pull on the other side of the connector with your fingers. Do not pull on the cable, because you can pull it free from the spade connector.

  7. Nespresso CitiZ Teardown: passo 7, imagem 1 %32
    • Disconnect the blue neutral wire.

    • Remove the power switch from the case.

  8. Nespresso CitiZ Teardown: passo 8, imagem 1 %32
    • Firmly grasp the power cable connectors and remove them from the power switch.

    • Removing the outer shell requires some force.

    • There are a series of tabs on all four sides of the shell.

    • Start by using a flathead screwdriver or spudger to pop the first tab.

    • Work your way around the case, freeing tabs as you go.

    • Remove the outer shell.

  14. Nespresso CitiZ Teardown: passo 14, imagem 1 %32
    • Extricate the control button wires from the case assembly.

  15. Nespresso CitiZ Teardown: passo 15, imagem 1 %32 Nespresso CitiZ Teardown: passo 15, imagem 2 %32
    • Remove the blue tube from the flow meter.

    • This part, which measures water flow, is referred to as a 'debimetre' in Nespresso's part lists. It is part # 932-9521.

    • Remove the sensor data cable.

  16. Nespresso CitiZ Teardown: passo 16, imagem 1 %32
    • The pump feed tube uses a clever retaining clip. Remove this clip with your pliers. It does not require much force.

    • Repeat this for the clip attaching the valve to the water heater.

  17. Nespresso CitiZ Teardown: passo 17, imagem 1 %32
    • Remove the valve assembly from the frame.

    Is there a general name for this type of connector - the metal doohickey on the end of the tube, plus the retaining clip?

    • Disconnect the power cable from the spade connector on the side of the water pump.

  19. Nespresso CitiZ Teardown: passo 19, imagem 1 %32
    • Remove the side panel from the other side of the unit. The tab positions are similar to the first side panel.

  20. Nespresso CitiZ Teardown: passo 20, imagem 1 %32 Nespresso CitiZ Teardown: passo 20, imagem 2 %32 Nespresso CitiZ Teardown: passo 20, imagem 3 %32
    • Disengage the tabs holding the top assembly to the case.

  21. Nespresso CitiZ Teardown: passo 21, imagem 1 %32 Nespresso CitiZ Teardown: passo 21, imagem 2 %32
    • Remove the front spout.

    • Remove the top case. Be careful, the button cables are captive to the case. Disentangle the cables and set the top next to the frame.

    • You will not be able to completely remove the top case until the circuit board is removed. (The button cables do not disconnect from the main circuit board.)

  22. Nespresso CitiZ Teardown: passo 22, imagem 1 %32
    • Remove the plastic outer circuit board cover.

  23. Nespresso CitiZ Teardown: passo 23, imagem 1 %32 Nespresso CitiZ Teardown: passo 23, imagem 2 %32
    • Power cables, from left to right: heat (white), neutral (blue), pump (dark grey), pump ground? (light grey), line (brown).

    • Disconnect each cable with your pliers.

  24. Nespresso CitiZ Teardown: passo 24, imagem 1 %32 Nespresso CitiZ Teardown: passo 24, imagem 2 %32
    • Slide the water pump out. The rubber vibration isolator doubles as a mounting bracket that neatly slides out from the plastic frame.

  25. Nespresso CitiZ Teardown: passo 25, imagem 1 %32
    • Remove the (rather over-engineered) silicon mounting bracket holding the coffee feed line in place.

  26. Nespresso CitiZ Teardown: passo 26, imagem 1 %32
    • Disconnect the latches and slide the heating assembly out of the frame.

    Wo sind diese Rasten. Ich bekomme Heizeinheit nicht entfernt. Das Teil sitzt drin wie angeschraubt.

    Danke für jeden Tip.

    Hat sich erledigt. Ich habe die Clipse gefunden. Die liegen jetzt auf meinem Küchenboden. Und siehe da, plötzlich geht alles ganz einfach ;)

    Ich kann immer noch nicht genau sagen, wo die Clipse überall waren. Ein Bild mit ein paar markierungen wäre hilfreich.

    • Free the latch on the right side of the circuit board and then carefully lever it out.

    • Don't use too much force on the plastic bracket on top of the circuit board because there are two vulnerable capacitors on the rear left side of the board.

  28. Nespresso CitiZ Teardown: passo 28, imagem 1 %32
    • The remaining cables can not be removed from the board. Don't try!

  29. Nespresso CitiZ Teardown: passo 29, imagem 1 %32
    • The BTB12 AC 12 Amp triac requires a large heat sink that is riveted onto the main board.

    • Voilá!

A tool or a bit for those oval-head screws can often be bought at suppliers for coffee automates e.g. branded "Jura", "AEG", "Siemens", "Krups"

Where is the heating element then?

Junhao Eric Tan - Responder

Hi Junaho.

Did you have a look to Step 26 ?

Christophe S - Responder

Mistankely, I plugged my Nespresso Inssignia to 220v, now is not turning on. Do you know if it has a fuse that may have to be replaced? Thank you in advance!

Cristian - Responder

Is there any way to turn up the heat? Needs to be over 190F during extraction to get the best flavor and mine appears to be outputting closer to 160F.

J Will - Responder

My Citiz is leaking took it apart and water leaking from a few areas. Any suggestions?

Theresa Gajecki - Responder

our machine quit crimping coffee cups so no coffee, only water. any ideas?

Victoria Brust - Responder

Does anyone know what voltage is used at the switches on top? (On/Off, Lungo, Espresso).

Thinking about adding an ESP8266 there.

tim1992 - Responder

Be careful this is non-isolated power supply. You will have 110V on every pin (Based that you are connected to earth.)

R M - Responder

FYI

Power cables, from left to right: heat (white), neutral (blue), pump (dark grey), **line also (grey) as directly connected to ->**, line (brown).

Alexander Judd - Responder

Hi please my one is leaking from underneath any digestion?

christeatro - Responder

Hi there my one is a magimix and is leaking from underneath any suggestion.?

christeatro - Responder

Open it and have a look!

VauWeh - Responder

In the picture background there is a box of a Nespresso Inissia, however the machine actually being handled (KRUPS XN7006) is a CitiZ machine. This teardown is actually a Nespresso CitiZ teardown, not a Nespresso Inissia teardown.

Hugo Catarino - Responder

I have taken a citiz apart to replace a brewing unit which was leaking water into the capsule tray. This seems to be a common problem. Ireplaced the brewing unit and fixed the problem. However i had a look at the old brewing unit and discovered to my annoyance that the real problem was the filter which the capsule pushes against under pressure and which pierces the top of the capsule.. It just pops out but nowhere can I find a replacement for this piece alone. You have to buy the full brewing unit. Anyway it would be useful if your stripdown could go this far as it would at least identify this piece

Frank Duffy - Responder

I am trying to diagnose my machine. Top part of capsule is not getting punctured. Lack of any good flow. Some water is found in the capsule tray. I have seen the same symptom elsewhere, when someone says “water is leaking in the tray”, how much water (all of some)? Where did you source your brewing unit (in the US)? I don’t wish to pay out $50 and find it is the wrong type for the machine (Nespresso Citiz with frother - Type D122, not a Krups as shown above). Thanks in advance.

Dennis Mellina -

Anyone know what the brass compression tube fitting is called that slots within the retaining clip is called (in steps 16 & 17)?

Andrew Jenkins - Responder

Has anybody thought of replacing the vibration pump with a rotary one?

Vladimir Vanek - Responder

No, why? A rotary ump and 15 bar? Puuh…

VauWeh -

Could be possible to remove the outer shell without dismounting the base? I’d like to give them a paint job dismounting the less possible

Doctor Apple - Responder

Our C110 machine (one of the original models) stopped heating above lukewarm and the pump seemed to run fine. I did a continuity test between the white wire that goes from the “heat” connection on the board to the heater, and the “Line” connection on the board and it appears to be OK whether I touch the light blue or red wires. Does that indicate my heater is OK?

Bud Shaw - Responder

!&&* this one is ok,

Nespresso type D122 power not on but power plug put in line pump motor continues working what reason . Thanks

Hameed Ummer - Responder

Can you get a better pump and replace the one they use? I’d like to get a stronger one that is also quieter if anyone know where to get them.

Manlius Renovations - Responder

The pump is a Invensys CL4, now ARS CL4. (Google for it). What do you mean with “stronger"? It IS strong, making a pressure of about 16 bar, and more pressure does not make sense. If you want to have a change, try a ULKA EX4, but there will not be a great difference. Look for the right voltage.

If the pump does not work well, maybe its worth to carefully open it and clean it.

VauWeh -

Why is there no instructions for tearing down the brewing unit? Lots of problems with water leak and other stuff involve parts or seals in the brewing unit.

andersmard - Responder

Hi my machine coffee disperse no power light. But the milk frother side have power. May I know why no power going to the coffee side

Bill Ong - Responder

Did you ever find a cure? I tried to descale my Citiz but think messed up and after a large hiss and puff of steam the machine now does nothing! although the milk froth unit still powers up!

Can it be repaired? if so how?

Thanks
