Problem solved. I managed to seal the high pressure steam leak with Loctite Blue. I used pipe sealing tape first. That did not work so well. If the connection at the boiler starts leaking again, I'll try Loctite Red. Thanks again to this forum's helpful participants

Eureka! I have been searching for my fix on the wrong side of the Nuova. I couldn't see the back of my machine because it was up against the wall. {image} {image} I finally pulled my whole table away from the wall and found the steam leak on the tank end of the connector pipe. That is the

Thanks, John, for more suggestions. I'll try to get a handle on where steam and/or water problems are originating. I'll mess with it tomorrow to see if I can trace the problems back to something I can fix or replace

Well, a restrictor blockage was not the problem. The restrictor provided a clear 4mm passage through the larger collar. I checked one group head. I only need one group to function as I am the only person drinking coffee in the house. The Nouva has some additional symptoms that may indicate another s...

Jake, Thanks for your suggestions. They make such good sense to me. I was given the machine by a barista who had it sitting in her shops' cellar for a few years. I rebuilt the machine myself in 2014 when I took apart every part and cleaned them individually. The only part I replaced at the time was ...

I recently got my rebuilt 1995 Premier S to automatically turn off the water pump at start-up. Now, I cannot get my group heads to warm up. The steam wands are steaming but my coffee is coming out barely warm. The group head water release seems weak at start-up and sometimes the machine clicks into ...

I have resolved the problem with my water pump not turning off by doing multiple flushing of my whole water system. For some reason after gallons of Dezcal my machine started working better. It is still not completely fixed and I'll list the latest issue in another repair post. Thanks for your help ...

Hello JRising, The pump running non-stop when the machine is on is the most recent development. I just ran it until the upper pressure gage needle went into the red. The site glass shows the boiler to be about 1/2 full. My water supply tank is emptying when the pump is on. I don't know what switch t...

My Nuova Simonelli Premier S two group is faltering. For awhile I could get one shot of coffee before the group heads would simply drip water and blow air through the portafilters. Now, I can't even get the water pump to turn off at start-up. I replaced the pump without success. Should I try flushin...

Finally figured it out. Nunas and Ministry of Espresso got me in the ballpark of what caused water to pour out of my steam wands. My hesitancy was in buying an $180 non-returnable water level regulator for a machine that I had bought and rebuilt for less than $400. (That included buying the tools to...
