Thanks Chris, got a photo (thanks Vespa) but much appreciated. Had a worry we had mis-directed her silicone tubes. I fear Anna is dying, we are sans espresso for the duration.
She is working but has serious hx issues. Lots of vibrating hollow noise when water pulled through but it quietens once the head is under pressure during a shot, though the coffee is awful, no solids being extracted. A manometer at the head shows her taking a few seconds to hit nine bar so she is extracting a fair portion of the shot severely short of pressure.
She has had heavy duty descaling, a new pump (could both be bad?), a new flowmeter, new inlet solenoid, new silicone hoses and a check on the 3-way valve solenoid at the head.
All that is left to consider that I can think of is any issue at the head itself, blockage (doubtful, she is really clean of scale), the possibility of us having two bad pumps (not impossible but unlikely given when the noise is present) or the motor, which was near silent with the pump dropped down off of it.
Boiler fill noise is normal.
Scary stuff chaps
Merry Christmas all by the way
