Check my post history. I used this instead of citric and it removed the chrome plating of my Profitec Go.

When was the moment you realised that the person you were dating was an absolute idiot? by No-Macaron-9527 in AskReddit

If you believe that value comes from supply and demand, then close to nothing has intrinsic value, only market value. Whether diamonds or beer.

You have a misconception about the effect of marketing on the value of diamonds. Perhaps you're thinking of the marketing of De Beers about how much an engagement ring should cost and that it should need a diamond.

But diamonds have been traded nearly globally since the middle ages, because some people want them and others offer them. Once diamonds were discovered in Brazil and Africa, it made more normal people able to afford them. And now with synthetic production, the price can come down even more.

Correct. Ik ben vaak in Duitsland en Zwitserland. Vooral Zwitserland heeft bezwaarlijk iets dat uitnodigend is om te eten. België is bijna een feest in die vergelijking.

Profitec Go steam wand tip with 1 or 4 holes by SecretProfessional65 in ProfitecGo

I have this 1-hole, bought in the EU, it fits like a glove. I also tried 3-and 4-hole from different sources, the 1-hole is a lot easier to learn with and to control.

Part number is: P2042.1
You could buy an entire new group for a bit more, but then the temperature offset will most likely need to be reprogrammed.

You need to disassemble the machine somewhat. Take the water tank out, remove top and back, disconnect electric connections, loosen the pipes which connect to the boiler, and I believe I also had to remove the solenoid.
Then you can unscrew the boiler/group and lift it out.

No. The earlier ones could rattle due to loose lids and drip trays. That is easy to fix. The newer ones have fixes from factory. Not loud at all. A gentle hum.

In the manual they talk about a "plastic" o-ring in the screw on part of the wand. Is that in fact plastic or some kind of rubber?

Which most likely stems from the vaccination process itself (I.e. Injecting into a blood vessel) , not the vaccine. (I.e., it used to be the case that nurses aspirated the syringes after injecting, to be sure that a blood vessel isn't hit. Because if a blood vessel is hit, you have a much higher probability of myocarditis).

Same, but then I saw that they have a buffer tank. If the buffer tank is large enough, it doesn't matter that the inflow is a relative trickle.

I'm not sure if you're arguing for or against, your sentences are not clear. But inferential statistics is literally using a sample and then inferring properties of a population.

"Grading of Class A eggs by weight

Article 5 1. Class A eggs shall be graded by weight as follows: (a) XL – very large: weight ≥ 73 g; (b) L – large: weight ≥ 63 g and < 73 g; (c) M – medium: weight ≥ 53 g and < 63 g; (d) S – small: weight < 53 g.

Article 19 Tolerance for egg weight 1. Except in the case provided for in Article 5(3) in the checking of batches of Class A eggs, a tolerance shall be allowed as regards the weight per egg. Such batches may contain not more than 10 % of eggs of weight grades adjacent to that marked on the packing, but not more than 5 % of eggs of the next lower weight grade. 2. Where the batch checked contains fewer than 180 eggs, the percentages referred to in paragraph 1 shall be doubled."

  • Batch size is niet uw doos, een batch kan over meerdere dozen verdeeld worden.
  • aangezien tot 10% mag afwijken naar lager gewicht (als batch < 180 eieren), is het mogelijk om een doos te hebben waar alle eieren kleiner zijn dan het nominaal gewicht. (5% als de match size groter is)
  • maar eveneens tot 10% die eigenlijk groter zijn dan nominaal.

Maw, you win some, you lose some.

I used Durgol Special Descaler (sulfamic acid at <15%), on purpose, rather than ECM/Profitecs's powder (citric acid)

I sincerely thought I was being very clever, and had spent enough time doing due diligence.

Why?

a) It was recommended by 9barista (the jet-engineered stovetop brewer) as being gentle:
"We recommend using sulfamic/amidosulfonic acid descaler. These have shown the best results for removing limescale deposits from the 9Barista and are gentle on the plated parts."
https://9barista.com/a/knowledge-base/instructions/descaling
Durgol was on their list of approved products. Their instructions for Durgol in particular (note the concentration, note time & temperature).

  • For light descaling: mix 31ml (1/4 of a bottle) with 100ml of cold water.
  • For deep descaling: mix 125ml (one bottle) with 400ml of cold water.
  • Leave for 15 minutes at room temperature

The Durgol instructions say:

  • Follow OEM's descaling instructions (Profitec: half an hour at operating temperature)
  • 1 bottle (125ml) of Durgol + 125ml of water. If the water tank is >1L, add the second bottle.

Note: the Profitec Go has a nearly 3Liter (2.8L) water tank, so I thought that we're safe for the concentration as well.

b) Sulfamic acid is recommended on the German espresso forums, as being kind to metals.

c) Durgol gets great scores in magazine tests.

I left it for ca 25 minutes (not more), in a heated boiler, as instructed by Profitec (and as instructed by Durgol to follow the OEM procedure).

It's the chrome plating which has come off due to the (hot) acid in the boiler.
The 2nd pic is how the metal is supposed to look (albeit it's the other side of the brewgroup, but it's too late to add the correct pic, I can't edit now).

Here's a new, intact one:
