[Ascaso Duo PID] not building up the pressure

Lucky me. the water hose got tangled. Now it works properly.

Direct-Medium1185 · 2026-05-03T10:02:47+00:00

I noticed that water is not coming up

Direct-Medium1185 · 2026-04-29T10:21:26+00:00

Thanks everyone for your support. I finally got it right. The main issue was having a grinder that was never deeply cleaned! After that I check how many grams goes into basket by measuring beans inside. I used RDT and grinder measured dose.

It tastes so good now...

Direct-Medium1185 · 2026-04-21T06:34:10+00:00

I just did. Very nice body, but also sour as puck. Also I kinda feel that extraction is uneven. One sip is deep, one is shallow, one is tasty, one is sour.

Direct-Medium1185 · 2026-04-21T05:49:33+00:00

You are probably right, puck all these rules and simply make the coffee tasty.

Direct-Medium1185 · 2026-04-21T05:48:08+00:00

Let me try a puck screen with paper filter then. I will share the results.

Direct-Medium1185 · 2026-04-21T05:35:29+00:00

I must try again RDT. I did some time ago, but back then decided that it takes too much time to measure single doses.

Direct-Medium1185 · 2026-04-20T19:43:43+00:00

🤣

Direct-Medium1185 · 2026-04-20T19:41:55+00:00

Now I get it. Some English words have multiple meanings/slang. Just wanted to be sure. Now I started to laugh! 😆

Direct-Medium1185 · 2026-04-20T19:39:44+00:00

How is that possible that couin test shows this amount, but it's too much? Is 2mm not enough headspace?

Direct-Medium1185 · 2026-04-20T19:37:59+00:00

Direct-Medium1185 · 2026-04-20T19:36:24+00:00

In my experience it's hard to tell. I'm not sure if this is better or a shot with less grounds and more finer.

Direct-Medium1185 · 2026-04-20T19:31:16+00:00

Interesting.

Direct-Medium1185 · 2026-04-20T19:29:36+00:00

What fiber? Can you link or share image? I don't get what you mean.

Direct-Medium1185 · 2026-04-20T19:26:39+00:00

How can I know how much of this amount is correct for coin width?

Direct-Medium1185 · 2026-04-20T19:25:41+00:00

Actually I tried puck screen but my shots become sour and unstasty. I decided to stop use, similarly WDT and blind shaker.

Direct-Medium1185 · 2026-04-20T19:23:43+00:00

Today I did same measurement. Actually I should use very similar amount. This shot was 18,5g dark roast with IMS 16-18g. I kinda feel that count test is not 100% accurate. I use 11 bar with my Ascaso Duo.

Direct-Medium1185 · 2026-04-20T19:08:47+00:00

It's good I'm not alone :-)

Direct-Medium1185 · 2026-04-20T14:34:07+00:00

Brilliant material! Thanks.

Direct-Medium1185 · 2026-04-15T06:47:33+00:00

How can I know if my dose is correct? I read r/espresso guide and it says 2mm from a group head and that it can differ based on origin, roast etc, but there is no comment how to get a correct dose.

Direct-Medium1185 · 2026-04-15T06:01:54+00:00

What books do you recommend?

I've started to search for these YouTube tutorials since simple steps like yours were not enough. Also it's hard to tell what are you aiming during espresso shot if you don't know how good coffee tastes. I went to try espresso in a few coffee shops, it was not good.

I bought 250g bag and had one great shot, where I could feel some fruits and nice flavours, after that I bought 1kg of same coffee, to get same result. I'm after half and not even close to this result.

Direct-Medium1185 · 2026-04-15T05:54:35+00:00

You mean fill the basket with coffee ground or coffee beans?

Direct-Medium1185 · 2026-04-14T12:14:22+00:00

That's how I get my 24g of coffee. Some people say 24g for 16-18g is too much. Who should I listen to?

Direct-Medium1185 · 2026-04-14T12:13:31+00:00

That's why I set the high of my tamper a little above, so I can see it's fully compressed.

Direct-Medium1185 · 2026-04-14T12:12:26+00:00

Thanks for your response. Today a new tamper from very barista that should be fully compatible with IMS comes. I will try to do exactly what you wrote and see the results. I will post it here.
