You’re right, I’m not familiar with the correct terminology. What I meant by “steam pressure” is the top portion of the manometer where it displays the word “Steam”, and it idles there around 0.5 - 0.875 after the machine has warmed up 30+minutes, prior to pulling a shot.
Once Mara X has finished the warm up cycle, there are two situations we are looking for on the manometer: Situation 1 is when the machine is ready to brew a shot of coffee. For this we expect the pressure to be 0.5-0.8 bar (call it whatever you want); Situation 2 is when the pressure is ready for steaming after a “steam boost” (around 1.5 bar).
My machine does not replicate situation 2. Here is a video of the machine pulling a shot, and watching the “steam boost” afterwards. It goes up to 1.25 bars
I didn’t get to do a timelapse video, but it’s the full 32 minutes of cold to warmup
You can see here that it maxes out at 2 bars of pressure while warming up.
@DavecUK I have actually had a great deal of trouble following the OP posts of the issue, because certain things are imprecise, leaving hanging questions..
is this all the time
is the user flushing the machine when they shouldn’t, because you flush HXs don’t you?
are they using the hot water tap and drawing a lot of water (because it’s there to be used, right
steamed, how much, to what temp (maintaining 1 bar is pretty good if i’m honest (is there a clue here?)
what country are they in (USA), is the programming slightly different?
30 minutes is in reality just properly warmed up and the machine may not react the same as 1 hour in because it’s still sinking heat.
was it purchased new/used, what’s the date of manufacture on the rating plate
Yes this is all the time in brew priority mode (X mode, coffee mode, whatever the correct terminology is)
I do not flush the machine prior to pulling a shot
I do not use the hot water tap
I am in the USA
The Lelit box says a manufactured date of 05/2021
I purchased this brand new, received on Monday 01/24/2022
The machine is on standby mode, however I’ve kept it on and ‘active’ during the testing by activating the lever for a second so that it does not go into standby mode. I will try to disable this later as well and test again after the machine has been on for a full 1 hour.
I will steam some milk later today and provide info on the amount, and time to temperature.
