If you dont like it i will be surprised. Red Bird came at noon but I had  already worked my way through 4 double lattes of Verve. Between myself, my wife and son,
cranked out 10 double lattes. I made last four with Red Bird but didn't drink any. Tomorrow I will drink some...Pulled very nice shots though. Two doubles are sitting
in disposable 16 OZ mugs to be turned into ice coffee later. Take those add some Tornai and ice and milk...and wow. Love my espresso machine.

Redbird tends to show up very quickly post-roast.  It may take a few days to hit its stride.

Good news guys.   Machine is back to normal operation again.

Got a new relay from Jim and swapped it out for the faulty one,  turned the beast on,  and up to 204 F it went.  

One little hiccup though.   The new relay Got from 1st Line wouldn't work without modification.   The cable that comes off the relay and plugs into the Pstat was  WAY too short.   It wasn't going to reach.   I wound up the longer cable from the old relay and soldering it onto the new one.   Did that and everything is working ok.

I sent Jim an email with a picture showing the different cables.   I'll let you know his response.

Just for reference, here's a pic of the old and new relay.  You can see the old one on bottom has a much longer cable that goes to the pstat.

The little plastic connector piece opens up and comes into 2 parts. basically all the connections are made at the relay end.

I don't follow.  

The cable is connected to the actual board.  There would be no way to get it to reach the way it was.

Yes, sorry. It has been a long day and my memory is wrong on that. I guess somebody just cut yours a bit too short.

I've seen dozens of these machines and have never seen one with the longer wire on. In my experience they're all the shorter wire which connects to a second short wire to the p-stat. Other than that, I have seen all sorts of different set-ups from the manufacturer's attempts to make less mistakes on the 120V machines for the north american market. I suppose different markets get different set-ups. Just be glad if you don't end up with one of the 120 volt ones rated for max.10Amps.

Well, it seemed promising yesterday, but turned the machine on this morning and the temp stalled out around 175 F again and wouldn't go any higher.  Smacked the machine a few times and it started to climb again, and stopped at 185 F so it looks like it's not the relay causing the issue.

No idea how or why this is happening, but all I did was pull the mushroom, clean it and the chamber, and then put it back, so I think the problem is there somehow.  Is there something I possibly missed?  Pulled everything from the mushroom, and replaced back in that order:  brew valve, spring, mushroom, gicleur screen, gicleur nut.  Is there something I missed?  Some nuance in replacement I didn't follow?

Would really like to get this resolved.

Let it sleep overnight with the 8 outer bolts out (4 on top, 2 each side)...
If it stalls again tomorrow, pull the top and the sides off carefully.  Does tapping the pressostat start it going again?  Does tapping the relay start it going again?  Does swearing at the little bastard start it going again?  You hvae poert to the power-switch and beyone, if the green light is on...  That green light and the common of the p-stat is just a short length of very cheap wire apart from each other.  It is uncommon for the pressostats to fail at a young age in a Cuadra, they have that sacrificial relay to die for them.
If your circuit is complete at turn-on, but opening at some incorrect point, then something in the circuit is imperfect. It'll most likely be the relay (I know it's only a day old, but it is a one day old piece of crap), or it is the element or pressostat (A Mater Pressostat is a piece of crap, too...  But not as foul as that clownish relay on a PC Board with a resistor belonging in a DC circuit).  Anyone else notice the "Ramp-Up resistor" on there? Good job, that'd be helpful if it were a DC circuit. Potentially it is preventing the opening spike from damaging that high-tech electronics of that powerboard that doesn't even shut the element off when the boiler is empty.
I shouldn't write about Cuadras on weekends.  I drink on weekends and don't have nice lies to say about them.

I found out last night how well mine worked. We had family and friends over and made 22 lattes with a double shot each and steamed milk and did it basically without stopping. It kept up very well. I am pleased.
