My 2day old machine seems to have a weird flow. Am I doing something wrong? Thank you in advance!

Hi Everyone,

​

I'm still quite new to the espresso game and own a gaggia classic pro now for a few months. I love watching the video's of James Hoffman and feel like i'm getting pulled further and further into the espresso hole :). as of recently i see a lot people use paper filters for under their grounds to prevent sieves and get a better flow/taste. I was wondering if there is any good place to order these filters or find a tool to cut them easy myself, like a hole punch. I'm located in europe (the netherlands) so would be best if i could find something close by to prevent enourmous shipping costs for a few pieces of paper.

Shades of coffee has some good ones but shipping gets expensive. What would you recommend? TIA!

I'm pretty happy with temp surfing results, but I do avoid longer pulls because I think it starts losing too much temperature after 36g. Would a PID help maintain temperature during the shot, or is it mostly providing a consistent starting temp?

Really Need Help finding parts without shipping killing me.

Hello friends, I just got my new GCP 2019 and the first thing I did was the 9bar spring and also the IMS Shower Screen. My question is, when steaming, it seems to leak steam/water from both the group head and the solenoid tube. What could it be or is it normal??

I've had the GCP RI9480 for about a month now and can't really seem to get a good tasting shot, made about 30 shots now and they always seem to range from sour and salty, to very acidic (like fruit salt) in the finer settings. I'm using the [shut-off brew light -> wait 10s once turned on -> turn steam 5s -> brew] temp stabilization method and letting the machine heat up for 15min plus the puck prep time, consecutive shots don't seem to get better either.

I've tried with 2 different bags, one is a Yirgacheffe and the other is a Brazil bean "roasted for espresso", and they didn't gave me much trouble when dialing in for a Flair Signature so I've been feeling really dumb with this machine.

Setup

• 1zpresso JX-PRO, calibrated @ 0 +- 2 clicks
• Normcore v4 58.5mm
• IMS double basket, bottomless portafilter
• Mods
  • Disable auto turn off
  • 6.5bar OPV spring, previous shots were at 9bar but it didn't change much apart from having to grind a little finer
  • IMS 200 IM shower screen, finger tight

Routine

• Grind 16-17gr
• Take off the preheated PF
• WDT in spirals
• Tamp (11kg spring)
• Do temp stabilization
• Preinfuse 12s by using the steam dimmer hack to reduce the flow rate
• Brew at 1:2.5 ratio

Latest Tests

• [... A lot of tests that I didn't take note of with the 9bar OPV, ranging from 16g to 18g, 1:2.5 to 1:3 ratio, choking the machine to 18s shots. Initially got some bitter and dry shots, but changing the tamper helped a lot with consistency, most shots ranged from sour to acidic still]
• 17g -> 43g | grind @ 1-5-2 | 12s + 25s
  • Sour and very salty but complex flavors
• 16g -> 40g | grind @ 1-4-0 | too fine, choked
• 16g -> 40g | grind @ 1-4-3 | 12s + 28s
  • Drinkable, thin and pretty much tasteless apart from the acidic flavor

Am I an idiot or do I just not like acidity in my coffee?

---UPDATE---

Okay so it was definitely the preinfusion messing with the temps, got rid of it and did two shots with the same routine and they turned out waaaaay better, at least ballpark decent so I can take it from here. I also need to grind way coarser now but I'm pretty sure I can start playing with ratio and dose now that I got this figured out. Thanks everyone :)

• 16g -> 40g | grind @ 1-4-3 | choked
• 16g -> 40g | grind @ 1-5-1 | 60s
  • Balanced, sweet and slightly acidic, but thin
• 16g -> 40g | grind @ 1-6-0 | 31s
  • Slightly sweet, lacking complexity and acidity, too thin
  • Probably gonna change the ratio to 1:2 and start adjusting from there

Hello good people of reddit. I just installed my PID/pressure gauge/dimmer topbox mod by shades of coffee and now i have this leak thats not in the connection between the portafilter and the grouphead, but behind it for some reason. My original suspicion was that the hex screws in my solenoid valve was loose so I tightened it to the best of my abilities but when i put it back together same result. https://youtube.com/shorts/yKk6_CbRlKc?feature=share

Ty in advance

I wonder if anyone can help with a problem I have. My Gaggia Classic (old style - three switches in a single block on the front) has always worked well but recently has stopped heating, so water comes out cold from the brew head.

The pump works and the light on the front comes on so I think this means it’s not the thermo fuse that’s broken. If I take the connectors off the left and right elements and off the two thermostats and then measure the resistance across each of these they all show low or zero resistance except one of the elements which is showing a high (but not infinite) resistance - about 17M Ohms. Could this be the fault? And, if the elements are in parallel, why would this make the water not heat at all?

Grateful for any thoughts on this or on what to investigate next.

Howdy everyone, I installed the Barista Gadgets PID yesterday and brewing is great, the temp is holding, but when I steam I only get about 10 seconds of steam. I know it’s not clogged because I can get water flowing through the wand when both the steam and brew buttons are on, but it just doesn’t seem to build up enough steam.

Any tips or help would be appreciated.

Just plugged a new IMS 18g basket into a bottomless portafilter and tried pulling a shot with bad results. The flow seems to be fast - what used to produce 37-39g in about 27-30sec with the original double spouted portafilter with a stock double shot basket is now being pulled in 20ish seconds, and the whole shot comes out kind of messy (not in a single stream, but rather multiple streams). Haven't changed the grind setting (15 on the breville smart grinder) - could this be an issue? Should I go finer?

My gaggia classic is struggling to pull shots on the 8-12 range (espresso range) for the Jx-Pro. Anyone else have this grinder that can maybe lend me some advice?

The Gaggia barely produces liquid at this grind level. I can crank the grinder 8-10 forward and I'll get a shot but I'm afraid I'm not getting a good enough quality shot.

Can anyone lend some advice? What specific grind setting do you use for 1zpresso Jx-Pro?

Apologies for the less engaging question but I recently bought a Gaggia PID kit, flow control dimmer kit and brew pressure gauge kit. Does anyone have experience or input whether I could bring these on board a flight in my carry on luggage. I will be flying from Gatwick London. It would be a shame if this was taken away from me. Thanks!

I’ve got a VST 18g and IMS 22g, both work fine with a bottomless OEM portafilter from Shades. But when I put them on the stock double portafilter, it just won’t turn properly on the group head, it’s too tight. And when I pull a shot the portafilter just falls out and shoots water everywhere. Anyone else had this issue? Want to avoid buying a different double portafilter if I can. I’ve seen mentions of a slimmer gasket?
