Thanks for all of your replies, guys!

The Slayer clip was really interesting. I haven't seen it before.


I can do the descale in the future if things decline any further. It is weird as I have other machines that are all fed the same water that has hardness less than 10ppm (calcium and magnesium). None has had scale.



I will persevere with the Lambro as it is. It is just a bit annoying to me to have something that doesn't work exactly as it should. :x

Why not just service the group? You can do it in minutes.

I have always found the lower valve on those "Zodiaco" Faema and EMI groups to almost always be incomplete and assembled incorrectly. You should be able to get some flow control otherwise why design it that way? It of course will not be as precise as a needle valve. The other function is as a check valve to prevent back flow.

Hi Paul
I have removed the bottom adjustment rod, spring, stainless ball etc and given it all a soak in Cafetto and then a clean in an ultrasonic bath and reassembled in the same order as was installed. It didn't make any difference in the available flow.

There is only a very slight difference in the flow adjustment from 'almost fully out' (so that there is no leak) and 'fully fingertight-in' (where flow stops).

You only got one spring below the bearing ball?
I thought yours should have two asin the drawing below.


You used this piuc of the controller of my machine:




In my type is only one very light spring.
What do you ave below the nut on top?
A screen liike mine or that little rod with one flattened side?

Mine is like the exploded diagram.
On the top it has a rod with a flattened side.

Yes...both springs are intact and in good condition.
