Dean: f02=3 turns off the boiler

Thanks Dave. Will do, and report again. I think the machine needs to cool off for multiple hours before room temp...

Just do it first thing in the morning.

I lowered the pressure so it would read 9 bars after the initial pause. It did not seem to work as well, so I changed it back.... an initial pause at 9 bars, and then a move up toward 10 with a blind basket.

Adjusted pressure on cold brew boiler to 9bar on the button, no dripping. Heated up the machine, the brew handle down, no portafilter in the grouphead, pressure jumped up to 11bar and there was a lot of water running from the discharge tube. Temperature variance was between 202 and 204. When the temp dropped, water stopped, and cycle continues, at 204, pressure is 11bar, water runs....
Put the regular portafilter, lifted the handle, the pressure dropped and then climbed up to 9bar. Bre handle down, pressure dropped to 6bar and then as temp gyrated between 202 and 204, pressure followed 6bar to 7 bar.

Started thinking that my PID is not set correctly, I1 was set to 0, changed to recommeded 005. Rest of parms are inline with CCS reccomendations... After that temp started gyrate between 201 and 205.

my guess is that such a variance temp is not normal, is it?

Dave, what are your thoughts?

and with I1 set to 0, temp variance is 202F-204F

There could be many factors making it difficult to diagnose if there is or isn't a problem. e.g. words like jumped up, lot of water all very subjective. I would recommend initially you ring the retailers (where you bought it from) tech department and simply go through it over the phone. I say this because things like when exactly, how much water, was the machine fully warmed up, how long was it warmed up for, is it more stable when warmed up after 45 minutes. What does Gyrate mean, how long to move up and down, up faster than down...what? Could you have reset the PID to factory settings without realising it, have you double checked all the parameters......

It's like posting on a medical forum "I have a pain, I think, because I've never felt pain before" and expecting some cogent response.

I realise it won't seem like this to you, but from where I am sitting, that's a little how it feels.

Tonyv138, how is the espresso in the cup?  That is really the key question!  No?

Sounds as if you have now adjusted it incorrectly....try this:

With the machine cold, switch off the brew boiler F02=3. Then check your pressure and watch the expansion valve outlet to see what happens in the drip tray. During the pull against a blind filter then after. Report back your observations.

Posted September 28, 2013 link

How fast are you lowering the handle at the end of the brew cycle? On my machine, it will occasionally do this. If you lower the handle slowly at the end of the brew cycle and shut of the upper valve in the E61 group before you open the bottom valve, my  machine will trap water between the boiler and the brew head and when the heater comes on it will heat up and cause pressure to rise above 9 bars...even though I don't think I have ever seen 12 bars. I don't consider this to be a big deal and it doesn't do it unless I lower the handle slowly.

Sharky: the espresso is good. Just want to want to make sure everything operates as design, so there is no future surprises.

Dean: i do not think i am slow with the handle

Was doing more observing today. It is possible that everything is working as designed. V2B was set up with all PID parms are set to those in manual, except I1=0. I1=0 is how CCS sent the machine to me. That includes T1 = 203 and  T2 = 255. Machine was fully heated for at least 1 hr.

Following my observations: OPV looks to be set to 11Bar. Brew Boiler temp cycles between 202F and 204F. The cycle from 202F back to 202F takes appropriately 90sec. Boiler pressure guage follows the temp movement up and down. Water drops into the tray are there on occasion, not much. Steam Boiler temp/pressure cycles in a similar manner 254F to 256F and back

I would be curios to see if anyone could observe their V2B in a similar set up and provide their input. If I do not heear back, i'll call tech dept tomorrow to verify, per Dave's advise.

Tonyv138, my settings are similar to yours . . . T1 was set at 204 and I lowered it to 202 (I am looking for a little more fruity flavors in my shots).  For T2, I also lowered it from 255 to 254 as I am at a much higher elevation here in AB.  So far, it is making amazing espresso . . . the steam is great, but the latte art . . . well, it is a work in progress!  LOL!
