Subject: Crossland CC-1 Temperature problems
 

I recently got my hands on a CC-1 machine, to replace my dying Gaggia. It works wonderfully, except that the shots I'm pulling are too cold. Even with the PID set at its max of 210, the espresso seem to be coming out tepid at best. I'm looking to find a thermometer to see what the actual discrepancy is in degrees. I've also contacted crossland coffee themselves, I'm just wondering if this is a subject that has come up in discussion here, or if anyone else had the same problem. I wonder if my PID might be miscalibrated.

I did use the search function, but didn't see anything elated to my problem.

thanks!

I believe others have had this problem, and there are some offset options that may need to be adjusted. Mine works fine, 200 degrees is 200 degrees. I'm assuming since you've had espresso machines in the past you know to warm up your machine 20min or so first. My boiler heats up to 200F in minutes, but the group is still room temp. Usually I pull a blank shot after 20 min, and after that the group is too hot to hold onto to with bare hands (and it heats up your cup).

I would say wait for advisement from the manufacturer before fiddling with any of the P menus.

Yeah, this isn't my first machine. Doing a couple flushes helps a bit, but It's still too cold when I pour. I've had the machine on all day. I figure its the "p" menus. I have no diea how to adjust them though.

There is a temperature offset setting.... I think it's P9 in the menu. My CC1's temperature seems fine... So I would figure out a way to take  a good temp measurement and go from there. If the shot seems like warm then there is something definitely wrong.

What did Bill say, sounds like your offsets are either off or not adjusted right for your area (offsets can help with people living in different climates, altitude etc). Kinda like how the Brazen can be adjusted for altitude as that can affect boiling points and temps.

I think you are on the right track. You need to know what the brew temp really is before making any adjustments.

Thermocouple based devices are more sensitive than thermometers so they are better at sussing out the temp at the brew group. They do tend to be expensive though and many may not want to make that kind of investment. The styrofoam cup method is not great but it is better than just putting the thermometer in the stream of water from the group.

Get a cup and cut it to fit the group where your PF locks in, this will reduce the volume inside the cup and tend to keep things a bit warmer. You may even want to pre warm the cup though how much that will do is something I am not sure of.

Poke the thermometer in the top of the cup so that it is in the stream and will be in the water as the cup fills.
This should get you in the "ballpark" anyway likely within about 10 deg F if you are lucky.

Do contact Crossland with the results and I am sure they will try to help you with the offsets.

I have played a bit with PIDs and installed a few in ovens and espresso machines but when it comes to programming them I am but a babe in the woods. Many people here know much more than I do about that.

I used to have a CC1 and I had to increase boiler temperature quite a bit to get a decent temp at the brew head. I actually had already bought another machine by the time I found out the brew temperature was low and when I fixed the brew temperature, the CC1 I had made much better shots. I had previously played with the boiler temperature up and down a few degrees but it didn't help. Turned out the reason it didn't help was because my brew head temperature was so low that making a few degrees adjustment left the brew head temperature still way low.


I think I ended up setting P9 to -12. I setting yours to -12 probably not the way to go until you measure the brew head temp.


Here is a thread where it was discussed:

When I talked with Crossland coffee, I gave them my model number. Apparently my machine is out of date and will benefit from some upgrades. They weren't clear on whether those upgrades would have any bearing on temp. Even at 210, the temp is way too low. My shots are tasty, yes, but they're also far to light, and completely lack the robustness and nuance of a shot that would be pulled a bit hotter.


Bill at Crossland cautioned against changing my "p" values, but I think I'm going to give it a try anyways, as my espresso is just too disappointing right now.

As far as atmosphere affecting heating, I'm on Vancouver Island and Crossland is in Seattle (as far as I know), so there will be literally no difference. except metric :)

It's probably best to follow Bill Crossland's advice. He's the engineer that designed the machine. Altitude doesn't seem to be the problem, since  Victoria B.C. isn't far above sea level. Maybe you have the original version of the CC1, which has since been modified (new version is 1.5). I believe the early models had some kind of electrical interference problem, which might be what you're experiencing. Did Bill say if he is sending you any parts to upgrade your machine?

I do have the original version, and Bill is sending the parts. His caveat to messing with the pid was that I can always reset it, so I'm going to dive right in tommorrow
