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.  :(

Also, if you're looking to try a new coffee on your Cuadra, seriously consider 1st Line's own blend, Fattobene.  

This stuff is fantastic!  Easily one of the best tasting shots I've pulled on my machine, and I've tried quite a few so far.  While at the shop, Jim whipped up a latte for me and it was exquisite.  

The shot I pulled at home, a hint of blueberry at the start, and then very chocolaty with a great mouth feel.  It really is a great blend of espresso.  Highly recommended!

Thanks. I do want to get to the bottom of this! I sent you an email about the injector pipe. Please check your email.

Again, thanks! This blend took over 6 months to self-create and perfect. I have received different feedback on this coffee from hints of almonds or tobacco... right into dark chocolate. I guess it depends upon one's tastebuds, machine, and grinder. Also, this blend has an optimal taste at 10 days after roast.

I use the spoon method that you can see near the top of this page.

It works every time.

Posted May 27, 2013 link

Thanks for the spoon advice.

It comes off very easily, and I'm happy to see that it's all perfectly clean under there (just a tiny amount of dried coffee bits since I haven't detergent-backflushed in a few days)

I would like to give it a try, but $10 shipping on a pound of coffee is a non-starter for me.

Replace the relay.  It has burnt its contacts and become coated in carbon. Instead of a clean metal on metal electrical connection, your current is flowing through the thin larer of carbon which is heating the hell out of the thin, copper contacts in the relay and they lose their rigidity and break contact. Your machine stops heating because of the relay failure, without heating it never comes up to pressure.
I would suggest upgrading to a much better relay, like a decent solid state relay. This has all been pointed out before.  If you want pictures of how the upgrade is possible, send me an email.

Or for a permanent link, someone could have my photos and the write up, and put up a URL for all coffeegeeks to see.

Could be...
But doesn't explain why it kicks in to operate normally after a flush - only that it might kick in after banging the side of the machine.
So what's the boiler overheat safety thermostat system on this machine?  Resettable type?  Can you get a meter on to it?
Or bypass it to test (don't leave it unattended though if doing that)

The relay has already been replaced with a new one and still had the same issue right after, so I don't think that's it.

Jim has a few more things for me to try and if I can't get it to work, I'll take it back to him so he can look at it in his shop some more.

I still think you introduced a leak by opening up the top of the group? I imagine you have some sort of pinhole leak that allows the heat exchanger to lose a seal and stall the thermosyphon. I don't know where the water would go to impact the temperatures so dramatically, though.
