Hi every body
when i raise the lever. the pump start humming but for several seconds no water coming out then the sound is changing and water coming out
some times the flow is very poor.
This happen also without any coffee in the basket.
i checked several times when it happens, and the steam from the steam pipe comes out O.K.
i have ROCKET CELLINI 7 years old.
i have not descale it for a long time cause the manufacturer recommends to do not do so.
Can any one advise?
Thanks in advance.

Change the pump maybe?

I agree on the "change the pump", so long as we're talking about a vibratory pump... (The Cellini Evo R has a rotary).

If the water hardness is low enough to avoid scaling, that's a fine recommendation. But if it's not, eventually the boiler, pipes, and gicluer will be clogged with scale. Here's the poster child for why water treatment or regular descaling are required:



Follow the instructions in Checking an E61 Espresso Machine for Scale. If that's not the cause of the flow problem, then start from the pump and work forward.
