  • Recommended descaler for a HX machine with copper boiler

    Hi, I have a HX machine with a copper boiler (Bezzera BZ 10). We run off tank water so scale is not really an issue, however was going to buy a commercial product to run through it (probably annually). I was looking at cafetto - restore. Is this a suitable product? - I ask as one seller notes: "- Safe to use on aluminum, brass and stainless steel." -- however this statement is not documented on the actual cafetto site? I have a nickel plated copper boiler (apparently), so unsure if the product is suitable, comments & recommendations welcome. I've searched the forum, but not managed to find any recommendations or discussion on commercial products (plenty of citric acid & why not recommended though). Cheers,

    Does it need descaling? Don't do it unless you have clear evidence of scale.

      Pull your Gh mushroom and inspect.
      Post up a pic here if your not sure.

      Seems it the current craze here to descale much and often.

      There is a sticky in the machine section about descaling.
      Interesting read.

        My pressurestat clogged up. Reading up on that recommended removing scale & a manual jiggle. It's fixed now but thought an annual descale might be a useful bit of preventative maintenance. My machine is 6yrs old without issue other than that.

          No mushroom on the bz10 as it's not an E61 group, rather bezzera proprietary. As per previous comment, looking at this as an annual bit of preventative maintenance - which might be overkill. I'll dig up the sticky ? Cheers,
