Hello
,My De longhi primadonna s hums when I go to get coffee. I feel like it is an electronic noise, sometimes it is loud and sometimes about quieter. I feel like it is in the back left.

In the back left sits with Delonghi the pump. How does it hum?

Hello
,To me it seems like a resistor or solenoid is humming, it sounds electronic.

What kind of machine exactly is it. There is a sticker on the underside of the machine that says. ESAM xxx. or ECAM xxxx

The description says ECAM28.46X

Could be a solenoid from a valve. Best times unscrew and see what hums there.
