I'm having a rough time finding the cause of this since it's the first time it happens to me.

Last week, I descaled my E61 machine like I always do. Since then, I have like a weird burnt plastic taste to all my shots.

I tried to rince the machine again and again, changed the water in the tank, backflushed the group with agent.

Tried 3 different beans and still ...

It's been like this for a week now and it's not going away.

I have a Rocket Cellini Evo V2.

Using same bottled demineralized water.

Please help me out !

Thanks

What brand descaler do you use and what's your procedure?

What brand of water, and do you have the data sheet for it's tds report?

My general advice would be not to back flush or put any other cleaner through for a while. I have a general habit that over cleaning or descaling machines can do more harm than good.

I would also investigate any plastic parts you can get to in your hx loop, and see if they were affected by your descaling solution.

As a quick test you could also try a few different kinds of water. If your tap isn't too bad it's not a bad test, filtered or different brand of bottled.
