Lelit Bianca with pump noise

liadaloni

Hi,

My machine recently make terrible sound that seems from the pump. She is 1 years old, not plumbed and I don’t think is pipes touching.

There is connection between the sound to the pressure (the needle vibrates). The sound comes after long IDLE and disappears after 14-20 sec, and maybe comeback in the next brew.

I checked the water reservoir, the pipe, the valve, everything seems fine with the water supply.

Any ideas?

Thanks.

umm, sounds a bit like pump cavitation, what water do you feed the machine? and any leaks

Softened by DVA.

0GH, 8KH.

When I pinch the tube to chock the pump, ita sounds different.

That’s absolutely not right at all…the Bianca is one of the quietest machines around, almost silent.

Have you removed the case yet?
