Version 3 LELIT Bianca PL162T: (Part 2: Temperature Offset)

Dear Friends, this video was made back in October 2021 during our trip to Host Milano 2021. It was a great pleasure to be able to visit LELIT HQ as well and we able to make this video on a condition that we shall not publish this video until LELIT had announced it.
So here it is, i hope you like it and excited as much as we do.
If you are owner of Version 1, it is perhaps a great opportunity to upgrade.
For Version 2, i would suggest to wait for next upgrade unless you have plenty of money.

Thanks Stefanus again for great video. Well I definitely will keep my V2 Bianca. Maybe it will be possible to make a program update in the future for V2 if so.

[@StefanusGoana]

You can upgrade your V2 if you want. Simply buy a new LCC and Thermostate

[@pastagandalf]

@@StefanusGoana but isn't there a new valve as well?

[@StefanusGoana]

@@pastagandalf yes a new solenoid valve

[@oomiodio]

After this video Stefano hasn’t slept for a week😂

[@StefanusGoana]

Hahaha in Italy we drink coffee almost every hour so yeah... just enjoy

[@vorna6664]

So with V4 we expect a 2in1 pressure+temperature gauge on the e61 :D

[@StefanusGoana]

You have great vision, Lelit should employ you to be their R&D team 😁

[@thedudewithpedal]

Just purchased the V3 in Indonesia 2 days ago. I love the espresso it can produce, the setup was easy to understand, looks beautiful. The only downside is I'm missing 1 brown rubber drip tray support out of the box. Any idea where can i buy the replacement? Thanks!

[@StefanusGoana]

Congrats on your new machine, but you bought from wrong shop i guess LOL, should buy from us

[@StefanusGoana]

Should claim from the shop bro, because it is still under warranty right?

Hi Stefanus, thanks for that video, very informative! I tried already with a darker roasted coffee with a negative Offset. With this one, I have right now, I tried with -5 and -3 and -2 an of cource 0. The best result I got for my taste is with -2. It's a great feature. But I have this question, I found in the Lelit extended guide (PL162T_V3_Extended_Guide_2022_REV00_web.pdf) on page 19 the following advice: "If you set a positive parameter, the result is a cup of coffee with more acidity. If you set a negative parameter, the result is a cup of coffee with more bitterness." But is it not vice versa? If the temperature increases during the extraction, the acidiy at the beginning of the extraction is lesser because of the lesser temperature at the beginngn and if the temperature decreases during the extraction, the bitternes at the end of the extraction is lesser because of the lesser temperature at the end of the extraction. Or am I wrong??

[@StefanusGoana]

Sorry i'm lost. Anything is possible at this moment

[@sAmiZZle82]

The temperature isn't less at the beginning with a positive offset. The temp is the setting on your PID. E.g. starting at 91°, if it notices your boiler temp tdrops from that temp it drives the temp at the boiler up (approx 5-8secs mid shot). Because the water has to travel through the group it loses some heat there anyway. But overall it will help to maintain acidity by keeping the temp higher. If you allow the temp at the boiler to drop -5 offset, then by the time it turns on, heats the water up in the boiler it will need to recover from an even more negative temp at the group. Hence you will have run with a lower overall temp for your shot which could bring out more of the bitter notes in the coffee. Hope that makes sense.

[@youtubeaccount7137]

​@@sAmiZZle82 but lower temp should result in more acidity and higher temps should result in bitterness? Or am i missing somethibg

[@pastagandalf]

What I don't really get... Isn't it just an offset added to the coffee boiler setpoint to get say 95 degrees right in the basket when you set it to that set point instead of the boiler being at the set point?

[@barjee8965]

No this in theory should increase or decrease the temp during brewing, you are confusing this with the boiler offset.

[@stylianos4570]

Hi, thank you for the great videos! Can version 2 be upgreated to version 3? Thanks in advance!

[@StefanusGoana]

Yes you can, but i would not suggest it if your machine is just 1-2 years old. V.1 upgrade V.3 is certainly the best.

[@001jozef]

My question is,did you try blind taste and try compare V2 vs V3 with offset settings and find noticeable difference and point your finger ,this is v3 and v2 shoots in term of temperature diference?Cheers

[@StefanusGoana]

Yeahh good one. I haven't done that really as i don't have them side by side. But what i can try is to pull 2 shots with different setting

[@user-iz7uc1tb5m]

Hi please give us information about PL82T we really enjoy your video.

[@StefanusGoana]

kzbin.info/www/bejne/lZOVen9sdreIqNk Hi i have video about PL82T before. Its a compact machine if you really have limited space. Its grinder can be the weakest point in my opinion

[@rolandlickert2904]

I assume that is a solid machine which will last for a long Time?

[@StefanusGoana]

Its been awhile since V3 launch, to be honest ao far i have seen 2 machines with faulty knobs, and 1 machine with probe not properly screwed, other than that seems like it

[@nazar7161]

Hi Stefanus! Thanks for the videos!! I am having a problem with Lelit Bianca p162. After turning on the machine, the LCC display, and the temperature rises gradually to the configured one (95 C). As it reaches the 95 it turned off automatically!!! Remove the plug out and then in, waited for few minutes, turned the machine on the LCC flashed for a second and then turn off. I can see the machine still warm! 😢

[@StefanusGoana]

Hi bro over herr i face a machine that the owner complain about the same problem. So he sent his machine to me and let me used it for the past 1 month. Strangely it never happens while in my place. So my conclusion is eithet electrical problem or water. Basically nothings changes except for those 2 thing at my place. I suggested my customer to change his water and let me know how is it going. Its been a week and i haven't heard from him again

[@nazar7161]

I totally agree with your conclusion! I tend towards the water as in my case was very soft 30ppm! My question is how to check that if the machine doesn’t turn on at all in the first place

[@StefanusGoana]

@@nazar7161 sorry i don't quite understand your question

[@StefanusGoana]

@@nazar7161 re activate your thermostat on each boiler

[@svm8058]

Hi Stefanus, thank you for video. What is benefit of using temp offset in V3? I understand how it works, but what advantages are?

[@StefanusGoana]

Its basically an element that you can play with to see how this effect your final cup. By not activating heating element at all during extraction certainly means you're brewing with lower temperature, compare to the same temperature all the way till the end

[@StefanusGoana]

If you are drinking light medium roasted bean then you probably want to make it +10 so to straight away activate heating element and able to anticipate drop of temperature during extraction. And correct me if i'm wrong most of the time light medium coffee people prefer to brew it longer from espresso to lungo

[@pastagandalf]

@@StefanusGoana does this mean a starting point for calibration of the value is the temperature drop that happens over a typical brew? E. g. if I pull a normal espresso and temperature drops from 92 to 88 while brewing, the offset value would be 4 and it would make the temperature more stable throughout the shot?

[@StefanusGoana]

@@pastagandalf hi a typical shot as water pumps out of grouphead, fresh water also pump into boiler. So let say you set brewing temp at 92 degrees. if i put 5 degree off set, heating element will turned on straightaway because the aim will becomed 92 +5 = 97 degrees. If i set for -10 this means 92-7 = 85, this means heating element will not activated until boiler temperature below 85
