Hello guys,

I'm experiencing a problem when steaming water. Steam/water/air seems to return to the reservoir and makes a very loud noise, like fire crackers exploding. It stops when I screw in the pressure valve up to 11 bar, but then it's making coffee with 11+ bar forever... or pushing the valve to 11 bar when steaming and putting it back when making coffee.

I replaced the screw of the valve, didn't help, I have a whole new valve that I could install, not sure that will help.

Any ideas? Thank you.

Best,
Dennis

anyone? Please.
