Something power related failed on my Leva this morning after turning it on. It was still warm, but no power to the switch light or PID, so it looks like if failed shortly after I turned it on.

I have not disassembled and diagnosed yet. Any ideas on what I should inspect or suspect is the problem?

First check the outlet with another appliance. Since the Leva doesn't have an internal fuse, check the outlet.

Then, check continuity through the main power switch, unplugged with an ohm-meter to be safe.

If the switch is good, but the PID is blank,I'd jump to the conclusion that the PID's transformer has failed. You could check if it is live on the primary and reasonably close to it's intended output on the secondary. Don't test a live machine if you're not absolutely sure what you're doing.

Thanks. Looks like a faulty switch.

Hopefully just the switch is bad. When I pushed hard on the switch, the machine did turn on, but it goes off as soon as I take pressure off the switch. Picture below shows a connector which got hot.

Dang, that looks toasty. Any indication of what caused it to happen?

No clue yet. I will replace the switch to determine whether that fixes it.

wow.. no internal fuse? any DIY to add an internal fuse to prevent other burnouts?

I found the exact illuminated switch for a Simonelli machine at voltage coffee supply. It should arrive on Monday.

If there is no damage to the wires, then the "hot" spot was probably just due to corrosion on the contacts inside/outside of the switch. Heat builds up and it's enough to fry those covers. If you change the switch, consider changing the female spade connectors on the wire side also. At the very least, clean and shine the female connectors so they make really good contact with the switch terminals or you may end up with the same problem down the road.
