Hi everyone,

I'm troubleshooting my DeLonghi La Specialista Arte (EC9155MB). Originally, the machine couldn't produce steam from the milk frother, but coffee worked fine from the group head.

I replaced the Solenoid Assembly (AS00003110), and now it's the opposite:

Steam works perfectly, but no water goes to the group head - instead, all water goes through the discharge hose into the drip tray

If I reinstall the old EV3 (right-hand solenoid, closed top, in the attached picture), the group head works again, but steam fails. So the issue seems isolated to EV3.

I suspect the new EV3 has reversed NO/NC internal routing, so it energizes the discharge path instead of the brew path.

Has anyone run into this with DeLonghi dual solenoid assemblies? Is there a part number that specifically matches the "brew" version of the EV3 valve?

Any insights, internal diagrams, or sourcing tips would be super helpful.

Thanks!

Alireza
