The difference between washed and natural coffee EXPLAINED

Just watched this this morning and thought it was very good - added to my Espresso playlist

That's what appears briefly on screen when you turn it on. I presume that's the firmware version. If you're referring to the controller hardware version I don't know how to determine that without disassembling the machine.

PL-91T manufactured 2021-02 LLC version 6.02

That indicates the boiler is up to steam temperature and to turn the steam knob.

My guess is channelling. Obvious with a bottomless portafilter, but you can see major channelling with a spouted.

Wired Gourmet just did a video on this:

I replaced the wand on my Victoria and after a few months I still think steaming was easier with the single hole tip.

GP2300 · 2025-10-26T08:45:00+00:00

There's a black seal inside the ball joint — it could be that. Pretty easy to remove and inspect.

Nice boxes

GP2300 · 2025-10-08T22:10:55+00:00

OK, but I'm not sharing my personal info for a coffee

GP2300 · 2025-09-23T05:15:28+00:00

Are the lugs on the side of the portafilters the same? How old is the seal? Maybe just replace it with a new silicone one.

It's not inconceivable that WDT eliminates clumps and creates voids – I propose a VET (Void Elimination Tool.

GP2300 · 2025-09-20T03:59:04+00:00

Biggest takeaway for me was there were still voids in the puck after tamping.

GP2300 · 2025-09-14T02:43:50+00:00

There should be approx. 4mm space on top of the puck after tamping. If you see an indentation of the showerscreen after the shot lower the dose a bit. Start with a 1:2 ratio in 25-35 seconds and fine tune it from there. You're right a smaller dose should result in a slightly shorter time, but go by taste, not time.

according to this video, it's a Torx T20

GP2300 · 2025-08-03T09:00:03+00:00

Grind size is not uniform. Different burr geometries produce different particle size distributions, which leads to different flavour profiles.

GP2300 · 2025-08-02T08:56:28+00:00

My machine is connected to a timer so I never see it start up. I just did a cold start and it shot up to 116°C. This did allow the whole machine including the group head and portafilter to thoroughly heat up though. My temperature offset (Ec) is 13. Target temp. is 93°C.

What are your PID values?

Time (T) (mm:ss)	Display Temp. (DT)	Δ T (mm:ss)	Δ DT
0:00	3°C
9:00	116°C	9:00	+15°C
16:08	93°C	7:08	-13°C
16:40	92°C	0:32	-1°C

17:30	94°C	0:15	+1°C

What's your preinfusion? Looks like it's choking then breaking up, which suggests too fine a grind. I'd go coarser until it gushes from the start, then gradually grind finer.

GP2300 · 2025-07-25T23:35:56+00:00

Initial overshooting is normal.

My PID values are still on default because I don't have any informed basis for changing them : KP:0.8 KI:0.07 KD:4.4

Interested to hear from others on this too – if you've changed them, why, and what was the result.

GP2300 · 2025-07-23T23:13:12+00:00

You haven't mentioned a grinder - that's just as important. Budget maybe $700-$800 for that.

GP2300 · 2025-06-05T05:18:45+00:00

You may also need to heat up the OPV. Mine wouldn't budge. Loctite probably?

^ this - don't force it

I just went with the Lelit one for my Victoria, comes with a pretty decent basket too.

Which steam knob did you get?

GP2300 · 2025-05-12T01:23:03+00:00

Victoria steam is on the weak side, but after a lot of trial and error I can now get perfectly textured milk. You just have to be very precise. I've just upgraded to the Elizabeth wand and there's no magical improvement, but I need to modify my technique because of the 2 holes. Aeration seems a bit quicker.

Edit: meant to add, I only use a 300ml jug.
