We really need to have a schematic of the machine to see how the circuit functions. I will try to find one and get back.

There's a wiring diagram at the Yahoo Gaggia Group (in my signature).
As you know, it is still necessary to join GUG to see the contents, but ....
just so you know, it IS there.

Thanks Susan, I USED to own a Gaggia commercial grinder, will they still let me in? :D

If you or someone else has an ohm meter and an electrically functional switch, post the ohms for every pin to every other pin, before and after pressing the switch.

Still looking to try to help, wiring diagrams have been found but a schematic is the tool need.

Hi, the switch is finally working, the problem is that it sticks, having to pull it to turn it off, so defenitely I need to replace it.  My dad lend me his ohm meter... How do I messure the switch terminals/pins?
I have meassured the frothing bolier and it is 22 ohms... but have no clue on how to messure the 4 terminal switch...
sorry but this hard head of mine has no experience with electrical circuits...

You will need to remove the wires from the switch to check it. Make a drawing of where the wires go before you take them off.

There are, as you know 4 terminals that the wires attach to.
Start with the switch in the off position, that is, no steam setting.
All you are checking for is; is electric power passing through the switch. You will either get 0 resistance or you will get no connection. Just like if you are holding the test leads in your hands, if they are not touching, you will not get electric flow, the meter will not show anything. Next touch the leads together, you will then get 0 resistance, the meter will go to the full scale deflection of the meter. These are the two conditions you are looking for, either connected or not connected. In MOST switches the terminals (when they have blade type terminals) are designed so that the blades of the terminals look like an    =     sign. that is, your switch will look like

A     C
_     _

_     _

B     D


Terminals A/B should be one pair of terminals and C/D should be anther pair of terminals. When you connect the test leads to A/B either one of two things will happen. 1, if they are NC terminals, you will get the meter to show power flowing or a 0 ohm resistance, or 2 you will not see any movement on the meter, just like if you do not touch the test leads together, then you have an NO switch.

A/B and C/D, would be, I would guess both NO connections, that is you do not see movement on the meter when you connect the test leads to the terminals. When you turn the switch on, I would guess that you WILL get movement and so, the switch is connecting the terminals together.

Make the check and let us know what happens. Remember, the wires must be off the switch, otherwise you will be seeing the circuit not just the switch.

Hi! Very helpful, I have a NO switch.  I found a similar switch that I adapted, it is a Single/double pole,ON/OFF Momentary NO.  My machine is now working like new again!  Thaaanks!  It did not fit perfectlly so I hace to open a little bit the aperture were the switch comes ot, but works perfectly for USD8.00!
