Coming from Bambino Plus, new with Lelit Elizabeth since 4 days, really happy to have this monster machine.

What I’m experiencing is burnt coffee, even with reasonable brewing time. I searched all over the internet without results… I give you all the details:

I’m brewing an Blend origin medium roast for a ratio of 1:2 (18in, 36out) at 93°C setup on the machine. I’m using a DF54 grinder with stock flat burrs. The total brewing time was total of 14s with 3s of preinfusion. I know it’s too little, I was expecting a really sour shot, but instead I got a bitter burnt espresso…

I changed all the advanced settings to Dave Corbey ones.

I start brewing after 20 minutes I turned on the machine, and before start doing that I check the temperatures of the 2 boilers reaching the correct targeted temps.

The preparation is the classic one:

- Purge a shot on the STOCK portafilter basket with IMG BigBang 18-20gr basket, and clean it, to warm it up.

- Taking 18gr of coffee beans measured with a small scale, and sprout a couple of shots of water for RDT, and mixing it.

- Slowly pouring the beans in DF54 while turned on, and placing the grinded coffee in the portafilter basket with dosator ring.

- I use WDT enough to make everything uniform without lumps, and I do a gentle bump on the mat.

- I remove the dosing ring and tamp with leveled tamper. I have also the NCD (distribution tool) but I rarely use it.

- I put a 1mm puck screen (so it’s like having a 19gr in the basket).

- I purge another fast shot (3s~), clean with microfiber cloth, and attach the portafilter to the grouphead.

- I place the cup pre-heated (I just place on top of the machine and it heates naturally) and scale underneath, and click the shot 1 button.

The result: 36gr of coffee, the coffee it’s not too hot, seems a good temperature. But the taste is bitter but the burnt bitterness. And the puck was really dry, difficult to pull away from the portafilter. Really strange with 14s of brewing at 93°C…

As you can see, I’m doing literally all the stuff people do when brewing coffee, maybe also more than that.

I need to understand if I’m really missing something, or if something is not working properly. It’s more like the machine even if it says 93°C it’s working at higher temperatures like 110°C or something like that… I don’t know for sure, I’m going by logic since 14s for a bitter burnt coffee and super-dry puck seems the only logical explanation…

Thank you in advance if you read until here! ❤️
