Steam wand is loud, any ideas?

    I've been using a Siemens bean to cup machine for the last year (it's been sitting there for years beforehand) and have been really enjoying making lattes, but recently the steam wand has been making a different noise... I can feel the jug vibrating in my hand and it makes a gurgling sort of sound that goes to a screech as the milk gets warmer, and I can't get proper microfoam out of it. I made a short video to help show what I mean:

    I'm definitely using the wand correctly so it's nothing to do with being too high or low. I also cleaned the steam wand, screwed it off/on again. I'm suspecting it's maybe limescale or a slight leak but no idea really... There's a single video online of someone disassembling the machine and an exploded drawing but I don't really want to mess with it if it's something I can fix. Anyone had this issue and have any ideas?

    Have you tried a descaler such as dezcal?

    I haven't used any descaler yet! I wasn't sure where I could buy one apart from online. Is it easy to get anywhere?

    I get it online, not sure if any of the coffee shops sell it.

    I think I'll try that before opening anything up, just to be safe! I am looking forward for it to be solved.

    Yeah, well worth a try before tearing the thing apart!

    My Gaggia steam wand does the same (specifically the screeching) after a few months of gross neglect. It's basically a blockage somewhere, so descaling & sticking a long pin up it and generally cleaning it should get it back to normal.

    It's looking like a scale issue alright - it's just popped up a message saying it needs a descaling. Hopefully somewhere local do the descaler, if not I'll grab it online. Thanks everyone!

    I'm sure you do this anyway but after every use, wipe with a damp cloth and blow some steam through to clean out any milk residue that may be stuck there.

    Yup, have always done that by principle - do not want yucky dry milk building up!

    Well, I found a DeLonghi descaler pack locally, mixed it up and went through the descaling program. Got the same noise again a few times but after a bit of poking inside the wand and letting it screech a little it seems to be getting back to normal! Now to enjoy my lattes without it sounding like a banshee :) I must descale it more often though, water in Laois is not exactly the best.

    On my DeLonghi bean-to-cup machine I have to set the water hardness level in the setup menu so that it knows how often to ask for a descale. They supply a little testing strip for that purpose with the machine. The water here in Bray is about as soft as it can be so it only needs doing very infrequently though.
