I would guess it’s two separate issues, since there are two separate boilers.
On the steam side—a quick check is to clean your steam tip, i.e. soak in cafiza or similar and use your group brush to be sure the holes are clear. Even with the foam blade tip, it will slowly close up over a period of months or years and I’m always amazed how much more steam I have when I finally clean it out! Also, the copper tubing may be scaling in, i.e. getting clogged from scale and reducing output. I don’t know of a way to check that except by pulling the tubing and looking, but a basic test would be to take off the steam tip and flow steam, and see whether it seems as strong as you’d expect or not. If the steam gauge is up around 1.45 and you have poor flow, then you have a clog somewhere. As to brew pressure; you can certainly try adjusting the pressure upwards on the pump and see whether it cures the problem or not. Before doing that, you might consider whether your pressure-stat is failing (and cutting out too early, i.e. too low pressure). If you search the archives, there are a number of posts/threads that discuss how to bypass the p-stat as a quick check—but do NOT leave the p-stat bypassed! I do think it would be unusual for the pressure setting on the pump to have changed, so I’d suspect the p-stat first. Other less likely things might be the over temp switches on top of the boiler (when they fire, it cuts power so usually wouldn’t get 5 bar or any pressure after it had tripped) and perhaps a leaking vacuum breaker or pressure relief? Hope you find the solution soon, let us know! best, Ben > On Nov 4, 2018, at 06:03, winnipegger65 <[email protected]> wrote: > > Greetings, > > Back when new, my Brewtus IV Rotory would have brew pressure of about 8 bar. > The steam pressure was very good making short work of steaming milk.
