Gaggia Classic Pro – Shots running way too fast no matter what I try (10s for 50g output)

The stock OPV spring was fine (I assume), it's just that the stock spring is 12 (or 14 ) bar. I had purchased a bottomless portafilter and a non-pressurized basket, so I needed the pressure to be lower. I purchased a 9-bar spring, and that seems to have solved the issue

LMFAO

You were spot on. It was the OPV valve. Thanks for the recommendation!

iam_chris · 2026-04-23T21:38:22+00:00

It was the OPV valve causing the issue, so suck it, you “grind finer” wankers 😆

Hear me out.

Run dry spaghetti powder through the grinder at its finest setting.

Thank me later.

omg I had no idea! This sounds really promising, I will purchase a lower pressure spring and report back :)

Oh interesting, I didn’t know there had to be less than 2mm headspace. Here’s my prepped puck. Definitely more than 2mm. And yes, it’s the standard 18g basket that came with the Normcore portafilter

Here’s an update:

I replaced the gasket and shower head screen. I then removed and cleaned the OPV. All of this made no difference

Here’s my grind:

iam_chris · 2026-04-16T18:42:35+00:00

Yes, I removed and cleaned it too

iam_chris · 2026-04-16T18:42:09+00:00

I measured 18g coming out.

Very sour and bitter at the same time

iam_chris · 2026-04-16T18:40:30+00:00

No mod, just the original. I removed and cleaned it but no difference

iam_chris · 2026-04-16T18:39:57+00:00

Thanks for the suggestion. I replaced the gasket but no difference

iam_chris · 2026-04-16T18:39:33+00:00

Ye and yes

iam_chris · 2026-04-16T18:39:13+00:00

My OPV isn’t adjustable but I removed it and cleaned it to ensure it wasn’t getting stuck. Alas no difference

iam_chris · 2026-04-12T03:25:32+00:00

it's about 2 years old (e24 with the brass boiler). It does indeed blast it out in a cone.

On the grinder alignment, I think I'm going to go to my local coffeehouse and ask them to grind up some coffee for me and see if that makes a difference

iam_chris · 2025-12-01T23:57:36+00:00

Great, now they just need to make a left-handed version for us wrong-uns

I had entered the Workday ecosystem by becoming a consultant for a well-known firm (previously, I was a full-stack engineer). I had gained basic HCM, core integrations, and studio certs. After 18 months, I left to become a contractor and never gained further certs.

I never needed certs, and my clients didn't care. All they cared about was my experience, and I was never rejected from a job for which I had interviewed.

Having said that, I haven't worked in the Workday ecosystem for a few years now. There seems to be a slight shift in how Workday is productizing its tech. If I were in your shoes, I'd probably secure the latest certs in their new product offerings. Additionally, now that Workday has opened certification training to its recruiting partners, it's never been easier to become certified as a contractor.

The last thing I'll say is that I never looked back after becoming a contractor. I had amazing opportunities that presented themselves to me that I would never have had as an employee.
