Question about Alessi "Coban" Espresso Machine

Open Question

Steam doesn't shut off

My steam arm seems to emit something closer to a smoke or mist which is not enough to heat and froth milk, When you shut it off it just continues to do so. I have tried cleaning out the two holes and the grooves in the plastic insert at the end of the steam arm and these are as clean as a whistle. It also seems like maybe the pressure to deliver the coffe might have reduced, I am not sure.

Delonghi perfecta milk not hot enough

Ummn - something in your Q. seems not right. The milk is not heated directly - its only heated by the steam as it passes by (and picks up) by the milk using a venturi effect - same as a spray bottle attached to a garden hose. You say you have froth - but you can only get that if you have steam... (it does not just blow air thru to create bubbles). So froth = steam & steam = heat... so milk must be hot.
Suggest you check manual for the 'heat' settings for your expresso as this may have been changed. While this is adjustable, the milk is not.

Also always heat your cups before using them - the silver cup 'holder' at the top does a reasonable job but boiling water does far better.
Cheers Mike

Expobar steam wand loss of pressure

Are you leaving enough time for the water to heat up to a sufficient temperature? Typically 20 minutes is needed to ensure good steam flow.

Coffee maker not frothing milk

The tube on the "ball assembly" which connects to the "milk" tank may be missing an O-ring. If this O-ring is missing, the steam will only siphon a little bit of milk because there is no seal. If it is working properly, the siphon can fill be expected to fill a cup in about 30 -60 seconds.

The steam wand is bubbling the milk, not frothing

THere is a little black tube inside - make sure its pushed out enough - about 1/16 an inch from the bottom. And you may have to clean it out. Happens to us too and after I do the above it works

Not frothing milk

that means that the steamer is not generating enough pressure steam.

This happens either because there is not enough heat, or if you release the steam when pressure is not enough.

Very common problem with the american maid makers.

bear also in mind that Krups are not the best at frothing milk, and this is also a basic model.

If you want the best capuccino Coffee machine, buy the italian ones, Gaggia, Delonghi, Ariete etc. that are all great at this, or get a bigger Krups as a replacement like the Krups XP405040 that is also good at capuccino

Milk froths at 1st then doesn't after 1 week

Ensure first that you are using the steam pipe in the correct way to froth the milk.

If it still does not work, that means that the steamer is not generating enough pressure steam.

This happens either because there is not enough heat, or if you release the steam when pressure is not enough.

If you think you are doing everything in the right way, then contact the company and insist for having the machine fixed or replaced.

Frother doesn't froth

Does not seem normal! You should get plenty of steam for the frothing. Since the unit is new you should take it back and get a replacement. The unit needs to increase the temperature for steam, route the steam away from the espresso group to the steam unit and the pump needs to activate to create the high pressure. Any failure in this areas will create your condition. It also possible that your steamer is blocked but this is a new machine so this is unlikely but you should make sure that it is not blocked.
