La CitiZ è una macchina per caffè compatta. Per poterla smontare è necessario uno strumento che la Nespresso non vende.

Puoi riuscirci con un paio di pinze ad ago. Le pinze piatte non sono l'ideale, in quanto c'è bisogno di qualcosa che riesca a infilarsi nelle fessure strette.

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

You can painstakingly remove them with pliers. Take your time.

If you can't get pliers to work, other people have had success using superglue, melting a BIC pen into the shape of the screw, or machining a custom bit.

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!)

Carefully open the lower case and set the machine on its side.

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.

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.

Disconnect the blue neutral wire.

Remove the power switch from the case.

Firmly grasp the power cable connectors and remove them from the power switch.

Insert the tip of a spudger into the silicon tube and slide it off the nipple.

Thread the remaining tubes and wires through the bottom case to free it from the main unit.

Remove the bottom case.

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.

Keep prying!

Remove the outer shell.

Extricate the control button wires from the case assembly.

Remove the blue tube from the flow meter.

Remove the sensor data cable.

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.

Remove the valve assembly from the frame.

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

Remove the side panel from the other side of the unit. The tab positions are similar to the first side panel.

Disengage the tabs holding the top assembly to the case.

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.

Remove the plastic outer circuit board cover.

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.

Slide the water pump out. The rubber vibration isolator doubles as a mounting bracket that neatly slides out from the plastic frame.

Remove the (rather over-engineered) silicon mounting bracket holding the coffee feed line in place.

Disconnect the latches and slide the heating assembly out of the frame.

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.

The BTB12 AC 12 Amp triac requires a large heat sink that is riveted onto the main board.

Voilá!
