I recently acquired several Astoria machines. One is an Astoria Sae1n. It has a problem I can't diagnose that I could use some help with. It fires up, the tank fills, pressure builds and is regulated by the machine, great. The steam is great. When either pressing the manual dispense button or one of the program buttons, it barely has any pressure, the pump does turn on though. The boiler gauge reads just slightly above zero and the dispensing gauge reads zero, though the boiler has plenty of pressure. These two issues may or may not be related.
