Pasquini Livia 90 faulty relay

I ordered a new relay but have not received it. I can see it clicking and will not stay closed. Is it faulty or could something else be causing it to click. Water level is ok. Thanks

If when the relay clicks, it then opens and clicks again repeating that forever, it's likely a bad power supply in the controller. If I was guessing, I'd say the replace the diode bridge and electrolytic capacitor, but that's just a guess.

Hi. I'm in the middle of repairing a Livia 90S also, and have posted a thread detailing the repairs, which were electrical: Pasquini Livia 90S with dead control module
I'll post the wiring diagram below. I added the red and blue arrows, in order to help me understand the current flow, and diagnose my machine.
You could certainly have a failed power supply relay, and hopefully your new relay will fix the issue. If not, you probably have a failing controller (the large black box). My controller was bad, and my entire machine was dead, as a result (I purchased it that way). I contacted Pat at Boyt_Enterprises, sent the controller to him last week, and received it back today, repaired, for $133 shipped.
You might want to take a look at your ground wires that are throughout the machine, and make sure they all test well, using an ohm meter. The other thing I would test and inspect, is the condition of the 2 water level probes in the boiler. The controller is looking for "input" from 4 sources, in order for it to send power out to the machine. So it wants a signal from the water tank, from the low level sensor in the boiler, from the high level sensor in the boiler, and from frame ground. Those 4 signals complete a type of "if then" logic circuit, and then the controller "allows" power to be sent out to the machine.
