I haven’t managed to destroy my all steel one yet, and this might not help your issue, but when I pour the hot water into the basket I hold it at an angle and start right on the edge, splitting the stream, this helps to prevent the disturbance of the puck. As the basket fills I stay at that angle and overfill it to preheat everything.

That's a good point, I pour from a swan neck kettle so presumably it goes in at quite a concentrated force and because of the curve in the neck at roughly the same spot each time! I'll try your side pour method tomorrow and report back.
Do you mean you pour over a sink and let the water overflow the top of the portafilter?

Hmm. They say specifically to pour directly into the middle, aiming for the silicon nib. That's what I do, until a cm or so under rim.
My pucks don't seem to have any of the cracking in these photos. They also do say not to read much into it, as when you remove the press after extraction, then repress to remove excess water / air it can easily crack the puck etc. there is a whole chapter on it.
If it helps :
- pour in ground coffee (about 18g)
- give it a mix with the wdt thing
- tamp down with mid force
- press in the screen firmly
- pour 95degree water directly onto the silicone bit (I just have a normal kettle)
- do the usual extraction
- 10 seconds with no pressure, but holding arms
- 20 seconds press (I don't weigh output, just press until the arms nearly touch the legs , maybe 2 or 3 cm away
- 10 seconds with no pressure, but holding arms
- remove cup
- just press excess water and air
- job done
- pour in ground coffee (about 18g)

Does anyone else with a robot find the little red grabber thingy on the shower screen fucks the puck up and causes channeling directly underneath it? I removed it, and it didn’t help as it leaves a larger hole. I then used 2 of the paper filters and that seemed to improve things, no channeling directly in the centre.
I don’t think it’s a long term solution though and wondering if anyone has experienced similar
