I've got a similar Laurentis machine, and I installed a thermocouple and inexpensive PID as a temperature monitor. I followed the lead of godlyone who I believe had the same machine as you. Here's one of his photos from his "refurb thread" that shows where the thermocouple is inserted for this group...

Jonny - very nice DIY! I may have to give this a try since I can't seem to find an aftermarket burnless wand for my CMA/Laurentis. Thanks for providing the instructions

I'll be interested to find out if the auto-fill solenoid on your machine is loud when activated/deactivated. I have a similar machine (Laurentis restore in "here"), and my auto-fill makes a loud CLACK. My 2 group Pasquini makes timid click by comparison

I don't know about Hydropure in particular, but the bypass in the Procons can be disassembled and cleaned

Perhaps something stuck in the pump's bypass mechanism that's preventing it from closing?

Dang, all it's missing is the shoulder harness. You're this guy, right? {image}

I did add a touch of wood to my first restore (documented in "this thread"). {image}

I think this might be the replacement HX for your machine: {link} $76

Take a look at "this post". The manuals are for Astoria, but the Laurentis is the same under the hood

Pink Martini is right up there for me. They do an outstanding unconventional Bolero that just makes me smile. {video}{video}
