No worries.  I just put it right back in as I wasn't having any problems with it in there.  Thanks to everyone for the replies.

Hey guys.

Wanted to give a quick update.

Let me start by saying Jim at 1st Line is a top-notch guy.  I've read great reviews from other customers about buying from him which had made it easier for me to purchase from him as well, and with good reason.

I was at his shop last Tuesday, and we spent well over 5 hours working on the machine, all at no charge.  Fantastic customer service.  

Was able to reproduce the issue there and Jim thought he found what may have been the problem, a leaky group.  He replaced all the seals in the group, top and bottom, and gave it a good cleaning and lube, so the group is, in essence, brand new.  No leaks to be found.  Unfortunately, that didn't solve the problem.  :(

Still having the issue with temp stopping when first turning on the machine after it sits for an extended period.  It starts to rise and then slows and eventually stops, each time a different temps.  Once it's 140 F, another time it makes it to 190 F, and a third time, it will climb to 167 F.  Odd.

Again, I get the temp to climb by either running water through the group, running water the hot water wand (I think this rules out the group as the issue), or gently wrapping the side of the machine.

Either way, I'm lost as to what the problem could be.  Like I stated in the original post, all I did was pull the mushroom to check for scale and gave it a cleaning.  Since then, this issue has been present.  I'm still working with Jim via email to try and resolve this, but he's just as puzzled as I am.  I'll keep you updated with any info, but as of now, still having this frustrating issue.  :(

Hi All,

Looks like problem solved. I keep my fingers crossed. There is an injector pipe for the cold water entering the boiler. There was a pinhole leak there, but this problem usually results in a hotter grouphead. After this part was replaced, we still experienced the same issue. We checked the 2 thermosypon tubes. Both were clear, but the upper tube had a flow restrictor which was partially limed up. We ran a strong descaler about a 7-10 days ago, but it is now apparent that when this problem occurs, the restrictor needs to be descaled separately. We performed a cold start up yesterday and today, and the machine hits 207 and 205 without any interruption.

 
Sincerely,

Jim:

I had often wondered whether this machine had a restrictor in the thermosyphon loop (or whether one could be added if not). When you get the time, could you show a diagram or photo of the restrictor's location?

Was this scale build-up from use or did it come from the factory with some scale built-up? Are they using hard water to test the machines at the factory?

I dunno about all Cuadras, but given where mine idles at (215F fully warmed up) and the speed of recovery after flushing, I would imagine that most do not have a thermosyphon restrictor.

the  machine leans toward being a dragon which is what got me to wondering about the restrictor. but at my current pressure setting the Machine idles at 205 with the portafilter installed and 210 with it out. I find it to be manageable atthese numbers.

Update on new machine:

Enjoying it so far.  The steaming capability has added some diversity to the beverage line-up.  We used to drink straight espresso only, now my wife usually asks for cap or latte type drink.  

I have become less tolerant of bad beans.  Alas for my wallet I am now buying freshly roasted beans from local supplier and they are 3-4x more expensive than grocery store brand...

HX uses a lot of water.  I am thinking of turning down pressure a bit since even when we use steam - its only for 1-2 drinks. My pressure holds a bit over 1.  Should I bring it down to 0.9?

I have not experienced any limescale on the Cuadras NIB. This machine definitely had scale from water usage as I saw it in the mushroom I removed on the first visit and manually descaled it (gicleur had a smaller opening), and then I saw it on the second visit again. So, the scale build up was from usage.

I think the last 2-3 batches had the restrictor. It is found in the upper thermosyphon tube right inside the elbow at the boiler side.

Getting to it hover near 0.9 max is optimal for espresso shot quality. However, steam capacity diminishes... For 1-2 drinks, I do not think it should be a problem.

I have to check with La Nuova Era as I do not see it on their parts list nor diagrams.
