MediumRoastSteam Give it a go with the PID settings. You have nothing to loose.

Many thanks to all persons who have replied to my question.

I have input these PID settings P=0.2 I=0.07 D=10 in my PL41PLUST. I set the temp to 94 deg and let the machine warm up during 30 minutes. Then I see that the temperature on the display is still fluctuating intermittently between 92 deg and 95 deg. I don’t know if this temp fluctuation on the display is really important or not. Because I do not have a Scace tool I can not check the brew water temp.

      PatC Perhaps there are other differences in the machines

      You can try playing around with the PID settings, perhaps increasing P a little try 0.03 or 0.04 and a little more on D, say 12.

          DavecUK You can try playing around with the PID settings

          I have now P=0.6 I=0.03 D=7 in my PL41PLUST. The previously explained problem of fluctuating intermittently between 92 deg and 95 deg seems to be solved now. Still playing around with the PID settings. Espresso is a hobby isn’t it. I have no tool to check the actual brew water temp fluctuations, so I just try to judge settings by temp on the display and by taste.

              PatC - also remember taste is king. Some machines don’t have temperature or pressure feedback, nor any means of monitoring such values whilst pulling a shot or idle, and they cost 10 times more than your machine. 😊👍

                Unearthing this thread as I’ve always been curious about the various tweaks. One I find a little confusing is EC. Mainly because I’ve seen various options. For instance I’ve seen Dave recommending 10 - I’m using this. I’ve also seen people recommending EC 8.

                And now I stumble on a video from Lelit Insider, from 2 years ago, and he advises 12 !

                Here are his recommendations:

                the origilnal works, but if you want try this KPC 0,5 KLC 0,0 KDC 0,0 Bc 30 KP 20,0 KLS 0,0 KD 20,0 Bs 30 Ec 12 Es 0 F 01 TR 1

                Anyone put a thermometer in the portafilter to see what the real offset is?

                Thanks!

                  pierrox - in the grand scheme of things… does it really matter? Increase the temp by 2C - do you like the coffee? Decrease by 2C… do you like the coffee? Essentially that’s all it is.

                      You’re right. I guess my ocd wants to know what is really the temperature I see on the pid. But then, if I wasn’t ocd, would I be into coffee? 😝

                          Hi all. Just found this forum after finding Dave’s extensive range of advice on the Lelit Elizabeth (which I only received yesterday having upgraded from a Sage Duotemp Pro). This is my first ‘prosumer’ machine when previous machines just did what they did without telling me much. First of the advanced LCC settings I changed was the TR01 to see the actual boiler temps. The fluctuation has been shocking. If I dare draw water for a tea the brew boiler drops to about 80C before then ramping up to about 97C before settling back eventually to the target I set of 90C. I was having to temperature surf if I wanted to make a coffee afterwards. Exactly what I thought I’d avoided by buying a good machine with PIDs. Also the preinfusion pump settings were all one second by default. Been really struggling so have gone through and applied all of Dave’s advanced settings now and the machine seems much better behaved.

                          Firstly what an absolute star Dave is to have gone through all that work to determine these settings. Secondly I have to say I find it slightly wild that the Lelit engineers appear to have got these settings so damn wrong. How can this be?

                          Thanks so much though Dave! Now that my machine seems to be less of a bloody handful I can start to hopefully master it.
