Evening all, first time forumite with a techie problem that I’m hoping you can help with. I have an Expobar Dual Boiler, about ten years old. It’s been good as gold all that time, apart from needing a new pump and PID about a year ago. This morning though, it stopped working after pulling my first shot. Symptoms are: I lift the lever, the pump runs. Normally after about ten seconds the brew pressure rises and coffee appears. Now though the pressure does not rise and nothing happens.
I’ve been asked when it was last de-scaled, and even though I’m in a very soft water area I’m sorry to say it’s never been done… maybe that would help?
Or maybe not. I’d be most grateful for any tips.
Best wishes
Mark
