My Starbucks Barista machine has no water coming out. There is plenty of water in tank. Steaming function of machine still seems to work, though not as strong. Tried to follow the priming instructions, but doesn’t help…never get any 4 ounces of water to flow through the steam wand as instructions state. Just a trickle of water, then steam.
If you haven’t descaled the boiler within the last few months then you may have some calcium build-up that is constricting the water passages or pump; you’re only getting a little steam out because what little water is making it into the boiler is being vaporized. Be careful leaving the machine on for too long in this state as an empty boiler can quickly lead to overheating and a ruptured heating element.
