Strange behaviour ATM with my Lelit Elizabeth. Every double basket puck (16g) is sticking to the shower head, this never happens with the single basket (10g). The only change I have made recently was to reduce the pressure to 9.5. Any thoughts?

to my knowledge it can be the result of a number of things. How much you dose firstly, see the coin test online If you change bean it can suddenly start to happen and you may be able to improve it but some beans are just worse than others If you grind too fine it can contribute to it In the end of the day if the coffee tastes good it doesn’t matter just wipe the shower screen more often after making cofffee! That issue pretty much stopped for me when I owned an Elizabeth when I bought an IMS shower screen

@"jcb1973"#215 other than the pressure, has anything else changed? It sounds like a simple case of too much coffee in the basket. The coin test that was mentioned by @"JahLaza"#31 mentioned goes something like this I believe: pop a 5 cents coin on top of a tamped dry puck, place the portailfter in the group head, pause, then remove. The coin should be ever so slightly depressed/indented. If it is pushed completely into the puck then the basket is overfilled. If there is not indent the it is undefilled. Someone please correct me if I have this wrong, it's a relatively new concept for me.

@"tompoland"#121 There’s actually no indent with the 5 c test, so maybe I am under filling the basket? I could also be grinding too fine , extraction times are 35s plus, there is a touch of bitterness. @"JahLaza"#31 - what was the shower screen you switched to?

This is no news and one of the annoyances with the Elizabeth. It is related to many things: Coffee, dose, pressure, etc. I get them most of the time. The key is to remove the portafilter and wiggle a bit so the puck dislodges. Friend of mine with an ECM Synchronika got them 25% of the time. So go figure. I actually went on and tested this almost to exhaustion, even took it to Bella Barista: Using a different grinder (Eureka 83mm flat) I pulled shots for 2 hours and had no sticky pucks. Went home using the Niche or a Feldgrind and guess what? Got stuck pucks! I can confirm that using some IMS baskets solves the problem for me at least. I currently use a VST 18g and accept the stuck pucks. Or use a puck screen. :-) See: https://www.coffeeforums.co.uk/threads/are-you-getting-sticky-stuck-pucks-please-give-me-your-feedback.56781/

Surely a puckscreen will fix this, no?

@"dutchy101"#p16965 or filter papers if (like me) you tried a screen and found it hard to get it completely clean of odd bits of rancid coffee 😧

@"MediumRoastSteam"#p16964 the voice of experience... nothing beats it.

@"jcb1973"#p16962 no indent, the yes mayb underfilling. With some machines (strong preinfusion pressure) this can create more channeling. It may not be a biggie but you can either try upping your dose a couple of grams or using a smaller basket and see if you notice that the pour is more even (assuming you are using a naked basket).

@"tompoland"#p16966 Interesting - I tend to give mine a scrub with a brush in hot soapy water after every coffee and also a soak in Puly Caff every other week.

@"jcb1973"#p16962 hi, I just realised I typed shower screen here. That’s incorrect, I bought an IMS competition basket and the stuck pucks pretty much stopped then. I never replaced the shower screen,I kept using the one that came with the machine. I had seen a few users reporting the stock shower screen with the Elizabeth is fine so no need to change that

Pucks sticking - double basket only

voegelin it is going to stick if you put too much coffee in. Just reduce your dose until it stops happening. If you reduce too far, you will end up with sloppy pucks . find the middle ground.

P S it is great that someone reads a thread that is older than a month and replies to it 🤔🤭🥰

@MediumRoastSteam

Thank you for all the info you provided. What’s the dose you use in your VST 18g? and you are running with dark, medium or light roasted bean.

Thank you for your help. I usually will check if someone brought this up already. 🥰

I was running with 18g with light/medium light coffee. Now I dose 19g in a VST 20g. Using a puck paper on top I am yet to see a stuck puck like in the olden days.
