I own a Delonghi Dedica EC685 and looking to get some proper microfoam for latte art, I removed the Panarello tube and tried to froth the milk using just the inner rubber tube.

Problem right now is that it works for a few seconds and then the rubber tube detaches itself from the pipe and it's propelled into my milk pitcher.

I did check the tube, it looks clean, nothing clogging it.

Any idea what can I do to prevent this?

Open the steam valve after it's heated up to release the built-up pressure. Then use it for steaming to avoid the rubber tip from shooting off due to high sudden pressures.

    Thanks for the advice, but actually I am already doing it. The shooting happens 10-15 seconds in the frothing process, and weirdly enough it happens in milk, soap water but not when trying with plain water. – maephisto Mar 26 '18 at 12:36
  • This might mean that your boiler is generating pressure faster than it is being released. Or the wand is partly blocked which causes pressure build-up. When was the last time you descaled your machine? Still weird it's not happening in plain water though... – Shiri Mar 26 '18 at 12:37
  • I've only had the machine for about 2 weeks and used it probably around 30-40 times so I haven't descaled it yet. I filter the water before pouring it in the tank, but the water is kinda bad around thsi parts, so I guess I could give descaling a try, see it it changes anything. – maephisto Mar 27 '18 at 11:10
  • @maephisto If you've only had it for 2 weeks, it's unlikely that it's a descaling issue. It might be an issue if you had not been purging the steam wand after steaming which could have drawn in some residue milk and caused partial blockage. It's not immediately clear what's exactly wrong and it could equally be a fault with the machine causing a lot of pressure build up. – Shiri Mar 27 '18 at 12:25

The same question with answers is here: Pannarello wand on Delonghi Dedica EC685 for latte art

The possible solution is to enlarge a bit output hole on the rubber wand.

  • I've tried widening the hole with a smooth chopstick. To no avail. I've tried widening it with a hot needle. The rubber seems to be of a good quality thickness. Still didn't give me a hole wide enough. Any ideas on how to widen this hole? – farankoshan Aug 29 '18 at 7:37
