[SOLVED] The Rotary vane pump was frozen and could not get unstuck. Replaced it and everything is good as new.
========================================

Spaziale New EK is all of a sudden delivering hot water to the head at half pressure or about 4.5 Bar. It also is very quiet when delivering this shot. It used to be much louder and used to vibrate more. I suspect some part went out. Ideas?

Is the pump dead and it's brewing off of line pressure alone?

If memory serve me right,
the Spaziale had few online screen that supposedly keep out sediments,
If I locate a schematic I will posted



no drawing yet that I located but
by normal possibilities:
in the entry water fitting
in the entry pump fitting
and by the flowmeters (is volumetric version)
if there are no sediment screen you could have also gigluers getting plugged.

oh that is a good thought ; it didnt even dawn on me that it might have enough pressure from tank to deliver some pressure through the head.

interesting - though this happened the same day ; I just remembered that we had a house water repair that day and the house water was shut off for 6 hours, but I left the machine on...
