@MediumRoastSteam Have you ever had Coffee Compass Sweet Bourbon? That is what I have currently resting, sat at 7 days right now. Just wondered if you'd ever had these beans before and if so could offer a starting setting for the Lelit. I drink black Americanos, on the Sage I always ran a ratio of 1:2.5 but have mainly been using 1:2 so far on the Lelit.

Had a mess around again with the decaf and put the machine at 90c and turned off the steam preinfusion, took about 8-9 seconds for coffee to start and looked very nice. 36g out in 33 seconds. This was fine as an Americano, no bitterness or astringency and I got about as much as you can from this decaf.

One thing that have noticed since pressing the + to see the actual temp is that say if I make a coffee at 90c then go to make another I will be waiting for the temp to cool down as it seems to spike up to 97c and it takes a fair while to come back down. Is this what you were talking about earlier @MediumRoastSteam?

Well @MediumRoastSteamI tried to get into the advanced settings and although I read that both buttons needed to be pressed one must have popped back as it said preset done and factory reset I think.

I switched it back on and it poured water through the group head for a while, for some reason now though the pump doesn't generate pressure anymore when brewing 😵

purging water through the group is normal. It's written in the manual. And welcome to the club, we all did it when getting into advanced settings. You'll likely only do it once.

Now, you saying the pump not generating pressure when brewing... What does that mean?

Apologies, after the reset I tried to make a coffee using the same settings as before but it choked, so I went coaser, choked, coaser choked and looking at the manometer there is no pressure being generated in the puck. After about 30 seconds I stopped the shots and I was getting drips. On removing the puck it had dry parts.

So I went for a 6 seconds pre-infusion but again no pressure being generated in the portafilter.

hang on. Something is not right. Resetting the machine should not influence on how coarse or fine you grind. When the machine was dumping water through the group after reset, did you let it finish the whole cycle?

Do this:

- Put the blind basket on your portafilter;
- Switch off pre-infusion on button 1;
- Hit button 1;
- Does the manometer needle move? It should start moving after 3-4 seconds and get up to 9-10 bar after 6 seconds or so.
- Let it do that for approx. 20s
- Hit button 1 again to stop.

A video would be great.

Please report back.

So, I think that I have figured it out.

When I refilled the water tank I think that the tubing must have kinked or something along those lines, I do now have the filter attached to the machine. I took the tubes out, topped up the tank and then everything is working again. Last shot was pulling just over 9 to a little under, water was dispersing before so I assumed it was ok. That's the only thing I can think it could be.

I will be looking to give @DavecUKsettings a go tomorrow as I ran out of time today due to "hosegate" I need to get a funnel of some kind as it is a pain pulling out the tank every time.

I did manage to get into the advanced settings without factory resetting which was nice.

It was strange to see the pump on time for steam set to 1 and for bloom 2.

I changed the LCC to show actual temperature which was nice, I noticed after pulling a shot at 93c the pump overshoots to 103c and takes some time to get back down. However a quick flush which is what I would always do anyway soon had the temperature back down to 93c. It's strange after the flush it goes back down to 93c and then drops to 92c so the boiler comes on and it goes back up to 96c and the cycle repeats. It didn't stay on 93c for a huge amount of time.

One other thing I forgot is that even when the machine is cold it takes Jedi master like skills to clean the machine without leaving the smear style marks. I'm wetting it with a soft cloth and cleaning with a micro fibre.

@Caffeinated_fiend - you won't see the bonkers overshoot if you use Dave's settings. 😉

You can use a microfibre cloth moisten with distilled water (like, condensed steam) followed by a dry cloth. Best done when the machine is cold.

if you want to make it super sparkly, 75% alcohol gel also does he trick very nicely. I use that sometimes. In fact, in Brazil, 96% alcohol is a box standard household cleaning product. Every household has it. Works wonders on many things. Bleach is hardly ever used, apart from toilets.

glass cleaner also works, from Halfords, not sure about the cheap nonsense from supermarkets.

@MediumRoastSteamthank you I will grab some.

Last night I changed my settings to the ones recommended by @DavecUKand this morning the temperature was so much more stable and the recovery rate is insane compared to the Lelit factory settings I was amazed.

Just out of interest, when it comes to pressure on the manometer what influences this, is it just grind size? Would a tighter grind push more pressure through the portafilter?

At the moment I am using Coffee Compass Sweet Bourbon 🥃 18g in 36g out in about 30-33s, no preinfusion. When the pump kicks in the manometer will go to a touch over nine and then towards the end maybe go just under. I noticed on some YouTube videos that the pressure was more around 11 or so and wondered why?

One thing I also noticed is that on my Niche I am lower than I used to be with the Barista Pro, for this Sweet Boubon I am at just around 20 and I very recently cleaned out the Niche so I'm pretty sure it's right on with the calibration.

I also may end up taking out the filter as I think it is making a little noise when the pump is in use which wasn't happening before.

Morning, does a ridged 18g VST basket fit in the standard Lelit portafilter? I don't need a bottomless for that? Is it only the 20-22g that require that?

I have been messing around with dose on the included IMS, I have tried 16-18g so far but when looking in the manual it states 14g for the included basket.

So: VST Ridged or Ridgeless...Will fit. VST 20g will fit too (I think this was discussed before). VST 22g.... I don't think so.

Ignore the manual. Believe in what you see. If you can put 18g of coffee and the compressed coffee is roughly below the ridge, you are good.

Alternatively, do the 10p coin test.:

- Grind, dose, tamp; put a 10p coin on top of the puck. Lock the PF. Remove the PF. Remove the coin carefully. Is there a deep indent? If so, decrease your dose. If a light indent, that's perfect. If no indent, increase your dose.
