Milk explosion - Isomac Tea
We recently got our machine serviced (Isomac Tea II...could just be a Tea) and part of the change was a new steam valve as the old one was taking forever to shut off and was down on pressure. Easily sorted, obviously.
Only problem is now we've got it back, the milk goes everywhere and the steam wand is really noisy when I'm steaming away. I thought it was just that I had pressure for the first time in a few months but the milk is going everywhere and I can't get any foam. When I say "going everywhere" I'm getting sprayed with a fine milk mist and it's somehow ending up on the outside of the of jug, again as a sort of mist. Smarter people than I can explain the science of that.
I did see a suggestion that the tip itself wasn't sealing and to wrap plumbers tape around the threads, so I'll try that.
Any other suggestions? I have tried using less pressure, adjusting angle, amount of milk, type of milk, same result. So I'm hoping it's not me...even played around with water in the jug to see if something was awry with the nozzles, but just got sprayed. Again.
Welcome slugga. Couple of questions for you - How many holes does your steam tip have? What size jug are you using and how much milk are you putting in it? If you sink the steam wand fairly deep in the milk can you get a whirlpool without making a mess?
I swapped a steam valve on an Isomac Tea a few months ago. The new valve/wand Isomac sent had a 4 hole tip on it where the old one had a 2 hole tip. They had also changed the threads so I couldn't refit the old tip onto the new wand.
I also think the old wand couldn't be swapped over to the new valve, I assume I would have tried that.
I suspect the same thing has happened to you. Check the steam tip and see if it has 4 holes. If so, you can poke a toothpick down 2 of the holes to block them off, that should make it a bit easier to use.
Thanks for the welcome and good question about the jug size - I'm going to say around 700ml. The "standard" size I guess (apologies for my general ignorance) We tried the plumber's tape and it has improved a fair bit. I'll try the deep plunge method and report back.
Only changed the valve, still got the wand and 2 hole nozzle. So that's a relief!
When I had my Tea II is put it in for a service and when I got it back they had replaced the 2 hole steam tip with a 4 holer, it took me ages to refine my steaming routine again but eventually I tamed it and produced consistently good textured milk. A 300ml jug worked well for me!!!
