Ferramentas utilizadas neste teardown

Este teardown (desmontagem analítica) não é um guia de reparo. Para reparar seu/sua Nespresso CitiZ, use o nosso manual de serviço.

  1. The CitiZ is a compact coffee-making gizmo. Opening it requires a proprietary tool that Nespresso doesn't sell.
    • 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.

  2. There are six ovoid screws on the bottom case. The screws look like rivets, but they are actually oval.
  3. 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.

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.

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.)

FYI

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

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

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
