La Pavoni Lever dual heating pressure switch for custom mod

La Pavoni Lever dual heating pressure switch for custom mod is used to convert a two prong heating element (the new style heating elements with simple switch), to the special function of dual heating.

It means that the heating cycles can now be modified to work in conjunction with the special dual heating white and red power switch, even if you have the simple and normal heating element.

More details about this special mod can be found on our FB group here: https://www.facebook.com/groups/lapavonienthusiastsgroup/permalink/892536725436619, with thanks to Juan J. !

The wiring of course needs to be modified in order to make this mod work on your machine.

Always consult an expert in coffee machines or get help from us for more info and details.

All mods are done on your own risk !

A small list of needed parts is:

• This dual pressure switch
• Double switch, white and red model: https://coffee-sensor.com/product/double-element-switch-for-la-pavoni-lever-ep/
• 5 female Faston terminals / connectors
• 1.5mm white cable
• Fixed wrench no. 14
• 2 fixed keys no. 17
• T20 security torx key
• Teflon
• Pliers
• Cutter / scissors
• Turntables

You can check the second product picture of how the wiring should look at the end. This can differ depending on the machine you install this pressure switch on.

Please treat the picture as pure example and not as a part of a tutorial.

If everything was done correctly, you should have on position I of the switch a maximum cycle pressure between 0.6-0.8 and on position II a heating cycle of around 1.5 bar max.

As on older machines, the position II is used for faster heating with the user always close to the machine or during frothing.

I would never leave the machine always on position II and leave it ON.

Also, the safety valve would constantly hiss on position II because it’s very close to the maximum working pressure that the machines were assembled for, during the factory process.
