<p>I have A DeLonghi BCO100IU espresso machine, but when I turn it on for espresso, even with a full boiler, no water comes out of the group head. I am certain this machine works on steam pressure, similar to a Moka pot. I have tried descaling with White vinegar and with descaling solution. Still, no water comes out of the group head. </p>

Does it really have a boiler? I assume this machine has a pump and a heater.

The instruction manual that I found online refers to a boiler.

@FrencDavid50 I see. Mostly this kind of machines for end users don't have boilers.
