Boiler pressure gauge should be showing in the green zone which should get you 195+ degrees.

    Top needle is your boiler pressure, bottom is water pressure. To adjust boiler pressure (with MACHINE OFF, of course):

    Remove large top grate on machine.

    From a birds eye view, towards the back left of the machine you'll see a silver box w/black cover (pressure stat). Remove the flat head screw on top and remove cover.

    There is an adjustment screw left of center with - & + adjustment. Turn one full revolution at a time. Turn machine on each time and check to see where the needle stabilizes.


    Be very careful this is 220 volts of electricty you are working with!!

    Regarding bottom needle (water dispensing pressure) this should read around 4 when not in use. When dispensing (pump on) this should be in the green around 8.5 to 9.

If you have hot water then the steam wands are blocked, either at the nozzle on the end of the steam wand or in the steam valve. The steam reading on the gauge should be at 1.2 bar, and the water pressure at about 3 bar until you run the group then that should read about 9.5 bars. You have 2 groupheads if you set the pressure to 9.5 when you run both at the same time it will drop to about 9 bar.

Astoria Divina SAE/2N 2 heads. What would make the spout in between the heads be only cold water and the water level gauge shows all the way at the top of the glass?

If by spout you mean tea valve, it could be that the economizer mixing solenoid valve is set to deliver more cold water when mixing. As for the level the silver probe on boiler.

Why does the pressure rise to over 3bar when the central heating is in operation ?

3 Bar = 43.5 PSI When you heat water it always expands increasing pressure.
In a closed vessel volume can increase by 2-3%. Either expansion tanks allow for this and PSI is maintain or without an expansion outlet the PSI will increase in proportion to heat supplied.
Is this a low temp hydronic boiler operating at or <140F, a hi temp hydronic boiler @ >180F or steam boiler?

Boiler pressure (steamer pressure) is at 0. Usually, when it goes down it comes back up in few minutes but not today. Also, the water coming out for our espresso shots is not as hot as it should be and our...

Problem is either the element, the pressure stat or the reset thermostat on the boiler left side if the model is equipped with one, has tripped, possibly because the machine is low on water in the boiler or the contacts for the pressure stat are damaged or dirty. First I would check the water level in the boiler then remove the left side panel and check the reset switch and press it in, then turn on machine to see if it heats up. If you do not have a reset switch on the machine then check the element and pressure stat to make sure they are working properly, do a resistance test.

I have boiler pressure and steam coming threw the wands but no water flowing through the brew heads. What could be the problem?

Either the solenoids are damaged or blocked, or the metering jet on the top of the group is blocked, or the blockage is at the flowmeters. Do you get a reading on the pump pressure gauge when the buttons are pressed?
