Hi, I'm EJ, and welcome to my RU-vid channel. I'm a designer based in Malaysia and I like everything aesthetics. I love BMWs and drink lots of coffee so you'll find those in this channel. Still on the quest to make good content on RU-vid so please support by commenting, like and subscribe if you enjoy my contents!
That's the plan, but it seems a little bit too technical for me and I need a longer time to research and study it. It's on my list for the next major upgrade but currently, I don't have the time to really dive into it. I am already in the Gagguino Discord and Groups and all but it's just too much information for me right now :D
I cannot advice further. You'll have to study the wiring inside the Machine. I think the PID works with many devices, as long as you find the right wire and temperature probe fixtures. Good luck!
For a 14G basket, i used about 16g bean. You can try but if it overflows, then just go with 15g or 14g. Depending on your grind size as well. You'll have to calibrate it to meet the exact ratio of your espresso yield. Rule of thumb: Bean to espresso 1:2 ratio, 30secs. For eg: 16g bean to 32ml Espresso within 30secs. Hope that helps.
Are these still having the issue with the “Boilergate” flakes ppl were complaining about 3-5 months ago after a month or 2 of owning the machine? I’m new to espresso machines and I was gonna pay when I came across those videos :(
Hi Ewejin, thanks for this. I got a Tune Up kit for my GCP before I received it. Brass shower plate, Precision shower screen and Silicone gasket. Once I got it I saw a video of a guy cutting three turns off the OPV spring to 9 bars. Next I bought a bottomless portafilter on Ebay from The Espresso Store. Shipped to me here in Costa Rica from Milan Italy for $45 total cost. I was happy with the machine but I was getting frustrated with tempereture surfing. I boght an Auber PID, Shades of Coffee Top Box, Flow Control and Preasure Guage. We added a second SSR for steam control. Very happy with the mods and I finally feel in control of my machine. When we tested the preasure it was almost exactly nine bars at full pump power. Cutting off three turns from the OPV spring was spot on!
Thank you for this nice video, i did buy everything you posted under your video, but Silicone Gasket E61 8,5mm was too big to insert portafiller holder. I have 2014 classic GAGGIA, I think my Classc GAGGIA never had a gasket, but there was some space. Maybe 4mm would fit. I just could find one
Well I haven't scientifically study it that much but for now, after I grind the beans, there are clumps and this tool helps just to break it apart. If you tamp it down directly, it might just form tiny air pockets?
@@EweJinTee I really don't know, we need some scientific data but air pockets? On a grainy substance? After compression? I seriously doubt it, but it is possible.... Some say that the clumps get even more compacted and this prevents it...maybe ... It would be nice if someone did a scientific study with blind taste tests
@@TheAllMightyGodofCod Let me know if you find any studies! After all, I don't let these bother me that much either. Just want to enjoy the espresso shot that I'm able to extract out and it seems descent :)
Thanks for the video, my issue was that the connector of the battery to the board got loosened somehow (even though I never travel with it). Thought I mightve needed a new battery like you did, but thankfully was a real simple fix.
what a great guide. Which kind of terminal I can use instead of piggy back ones? I am asking that because, I am not able to easily find ones without purchasing 100 units. Thanks
I think an alternative for you is to either try and purchase it from Aliexpress, or solder the wires togerher. But if you solder, then you won't be able to return it back to its original state in the future.
You require a 13mm socket for the 8mm nut. In case anyone wonders. Will you please keep us updated how long this lasts, I’d really like to know, thank you. Good video!
Does anybody know what's going on in this video? I want to learn how to do this but I'm a beginner and there isn't enough information for me to know what I need and what to do next.
He's essentially just marking (on the foil) and tracing it with a tool that uses heat. I recommend just getting a foil quil pen. They're only $30 and much simpler and cost effective, in my opinion
@@djmanosv I will still go for TIMEMORE because of it's build quality and price point. You can check out this one here: s.click.aliexpress.com/e/_DFKTqNt Or a mini version, which I haven't tried myself: s.click.aliexpress.com/e/_DDU9HLD
Too many things were upgraded together, so the conclusion is not clear unless you want to replace the all. Note that on a GCP EVO, some of these upgrades are already done.
Hi! Does this one works for the steaming temperature? I want to stop losing pressure while steaming, so I'm looking for a PID. But I don't know if this set up and this installation will work!
Hi. The PID will be able to display it's current temperature that is in the boiler. If you switch on the Steam switch, you can see that the boiler temp increases, hence it will be displayed in the PID display. So you will have an idea of what is the current temp and when is best to steam milk. I usually start steaming at around 150C! Good Luck!
Did you just change baskets between the two comparisons? So you can not tell at all if its the showerhead or the basket that changes the outcome right?
You changed the screen and the basket at the same time. Go back to school. You can only change one variable at a time. The basket is what made the difference not the screen.
Yes, the polarity matters. Make sure to follow the (+) and (-) closely. If your local voltage is 220V then it shouldn't be any issues running a 220V LED. If you're voltage is 110V, best if you double check as I'm no certified technician on this matter. Good luck and safety first!
I have looked around a bit on the internet and seen that many people like me have problems with the IMS screen, I have tried not to tighten it too much without any luck, with Gaggia original screen for me a steady rain drop with IMS it only gets 3 bigger water beams, the water is not distributed in the IMS screen as in the original, waste off money, unfortunately!
Oh man... i appreciate your hard work in making this video, and i see the point of you doing it as you want to demonstrate the importance of an upgrade in this machine which i also own with the proper modifications. But with all the respect i would like to point out some really big mistakes you are doing while testing and explaining. First of all the glass shot that you are using is very badly graded and you can notice that the distance between 0 - 15ml is twice as big as the distance between 15 - 30ml, even though the volume in theory is the same and should be equally graded on the glass. The second huge mistake you are doing is that you confuse grams for milliliters... as long as i don't see you weighing the output liquid with a scale that measures grams, i assume that you are taking the 30ml mark on the very badly graded glass shot as an indicator for grams which is very wrong. Liquid density can have a huge impact in mass compared to volume. As you can clearly see, you have 15ml of foam on top of the extracted coffee, which will only weigh approximately a third of its volume because foam is very airy and will transform into less liquid after it dissipates. So in conclusion you get out approximately 20-25grams of liquid instead of 30grams like you stated. That translates into an under-extracted espresso shot where you don't reach the full potential of the coffee. My only concern is that you do not take advantage of a proper and correct extraction since you are getting only 20gr of liquid output from 16gr of ground coffee. A rule of thumb is to go for a 2:1 ratio output:input and work your way from there in small increments, like 1gr steps. Try to aim for 32gr output from a 16gr input and work your way from there. It's not just my oppinion, this is how coffee science works globally assuming you are using the widely spread, medium roast, specialty coffee. In some cases, some coffee origins, depending on their processing method, require you to pull over 40gr of liquid out of 16gr of ground coffee to get the best extraction and best taste. I highly recommend using a proper espresso scale for extracting shots and really look for a precise gram reading instead of associating milliliters for grams, and work your way from the standard rules in small increments to get a proper shot of espresso and i promise you, you will enjoy the best coffee that this machine can offer. My setup is similar to yours with all the proper upgrades, 9bar valve spring, IMS shower screen, IMS basket, i got the newer Gaggia Classic Pro with the new stainless steel boiler and shower holder. And boy... i'm getting better espresso from my machine than i get from most specialty coffee shops using their own coffee. And that's because i use science, knowledge and precise measurements when pulling a shot. I honestly appreciate your work, and i hope that you at least try and correct the mistakes that i pointed out, and if you do, i would really appreciate tour feedback on my recommendations. Wish you all the best! Romulus
Dear Romulus, Thank you for taking the time to share your insights and observations on my espresso video. I genuinely appreciate your thoughtful and detailed feedback. Your points regarding the glass shot's grading and the potential discrepancy between milliliters and grams are well-taken, and I acknowledge the importance of precision in espresso extraction. I appreciate your concern about the under-extraction possibility due to the foam's impact on volume and weight. Your recommendation of using a proper espresso scale for accurate measurements and following the 2:1 ratio for output to input is duly noted. Your setup with the 9bar valve spring, IMS shower screen, IMS basket, and the new Gaggia Classic Pro sounds impressive, and it's inspiring to hear about the great results you've achieved through a scientific and precise approach. I'm grateful for your encouragement to explore these adjustments and corrections. I'll certainly consider your recommendations and aim for a more accurate and scientifically sound extraction in future videos. It's invaluable to receive guidance from someone with your level of expertise, and I'm eager to enhance the quality of my espresso with your suggestions. Once again, thank you for your support and constructive criticism. I'll be sure to implement the changes you've suggested and look forward to sharing improved content in the future. EJ
I have found that after steaming, if you turn the temp switch back brew setting and run a few seconds of new water into the boiler with empty portafilter, it will "steam clean" the group and lower the temperature down. This also refills the boiler and makes the system have less air. If you have air in the system, then your timing will be off as it takes more time for water to build pressure. Remove potrtafiler and wipe out basket and a quick wipe of shower screen. Put the portafilter back to reheat for later.
Hey. It's a 12V LED from some random electrical shop. I use a 4K temp for that slight warm look. Before, I tried the white 6K one, didn't like it as it was too bright 😅
Tamping on the spouts can make marks on the mat, but wont hurt the spouts. The portafilter is stainless or brass depending on years and 20-30lbs of pressure is not that much.
I was 'what, he isn't temp surfing', then I saw the PID. I use a bottomless portafilter, so I can put the scale under the cup and measure that way. I have the same scale. So far so good.
That glass he is using will fit around the spouts and you can slide a scale under it if you lift the glass first. What is neat with that is the spouts then keep the glass from walking away. This lets you weigh coffee in to drink weight out ratio. 16g in for 32g - 40g out. If the scale you have is to larger, the cheep amazon espresso scales work great sideways on the rack.
My especrience from recent change from stock basket to normal IMS indeed made better shots, but it did require redoing my recepie. At this point I am not sure if shower screen upgrade is needed. I guess it helps but not by huge margin. Most of bitterness in my experience comes from bad coffe beans and wrong recepies.
Try to adjust your recipe or grind settings first and give it a few more tries before making another change. We often keep changing the tools we use therefore we cannot achieve the result that we wanted. Good luck!
@@SunriseLAW Well close to perfection is good enough haha after all it's just a cuppa. There's no need to go through all that hassle for a cup of coffee IMO.
@@EweJinTee I agree with you totally. HEY! This might make good content. Have a Gaggia, wanted something for travel. Decided against Pico and Outin, bought the most unusual coffee maker EVER... the Bialetti Mukka Express off our local FB for $35, I thjink it is a 2006 version but it was brand new in the package.. It has a pressure valve on the basket. It is made for milk drinks but you can use it sort of like a Moka pot except it is super quiet and then the shot EXPLODES thru the coffee in 23 seconds. A little overcooked but... total caffeine extraction. There is no buzz like a Mukka Pot buzz.
Why do you purge some water immediately before the extraction? That will inject some cold water to the boiler, dropping the already stabilized temperature a bit, you can see it on your PID screen. I do something similar, but before grinding the coffee and preparing the puck, in that way I give the machine more time to recover the temperature of choice
The temperature in the PID displays a higher temp if you leave it On for a while. While I understand that the temp will drop a few C in the boiler but sometimes the first "gush" of hot water might burn the coffee ground in the first few seconds of extraction. This is just my interpretation and if you want to deep dive into it you'll have to try it out see if it makes any difference.
Hi Evejin, thanks for all that instruction , it was really helpfull. After setting pid parameters, pid aut light doesnt turn off and it does not heat boiler for brewing mode. When i turn on steam mode, i see the temp is increasing though. What do you think is the problem ? Thermal sensor itself or connections of it ? Many thanks in advance
Problem solved, i made a mistake on parameters, instead of 103.0 , i noticed that set to 10.3 which didnt kick the boiler since the boiler temp is already more than 10.3 :) but another problem is regardless from on/off switch, pid is always on
Thank you. My advice is to find a proper terminal for turning On/Off the PID. Some models of gaggia have different terminals. Use a multimeter or something to see which is positive wire and which is negative.
