Our cappuccinatore isn't sucking up any milk. Plenty of steam comes out, but it's also getting blown out of the tube the milk is supposed to be sucked up into. It was fine the first couple of times we used it, but we can't get it to work now.

Sounds like the venturi tube could be blocked. My model is a CVA 4085 and I can take the assembly out that sucks in the milk, mixes the air and stem and spits out frothed milk. If yours is similar, see if you can can reach the top of the milk outlet tube and rotate the ring around it anti-clockwise (if you were looking up from the bottom) and take the whole assembly out. If you have never taken this out, disassembled it and rinsed everything out thoroughly under a running tap now is a good time to do it. Then check the venturi tube: the clear (ish) bendy plastic tube that that points up and has a cone with a hole in the top. If that hole is blocked you won't get very good froth. If you can't clear it with warm running water then VERY CAREFULLY use a small needle to push through the hole at the top, then put everything back together.
it is clogged with dried milk. Remove the frothing wand from the machine. now press milk froth. you should get a ton of steam blowing out of the hole where the frother used to be. Your frother comes apart for cleaning. pull the chrome tip off, pull the 90 degree fitting and the black milk suction tube off, if it is really dirty you can soak the disassembled frother in hot water with a cleaning tablet. ( the small ones you drop in the brew unit, not the big descaling tab.) also, there is a clear tube with a point on the end of it sticking out of the frothing wand. this is an air admittance oriface. it allows air to enter the hot milk stream and make it frothy and bubbly. if it gets clogged, you will get hot milk but no froth. Your machine came with a spare one in the parts kit.
Had this exact problem a few times on a cleaned well maintained milk jug top with an ESAM5500M. Delonghi 'repaired' it by sending a new milk jug frothing top.
It's caused by milk fat deposits, the frother part on the milk jug may look clean but deep inside it's not. I clean mine with pipe cleaners, detergent and hot water and still it wouldn't froth.
The problem re-occurs for me every 6 months or so. You could buy the milk fat remover solution to clean it. Personally I just boil the whole milk jug frother in detergent and the again in descaling solution, that's fixed this problem twice now, although I think it will eventually corrode the 'o' rings on the frother, still cheaper than buying a new frother part each time though.
If it still doesn't work after that, the only other reason for this problem I found mention of was caused by a broken rubber seal where the milk jug fits to the machine. It's most likely to be milk fat deposits inside the frother though.
Most common cause of this problem is a blockage in the milk jug. First thing you should try is soaking the complete jug top in a quality milk line cleaner (available from specialist coffee machine retailers) for at least an hour and then rinse thoroughly. Then try running a fresh cleaning solution through the jug instaed of milk. Good luck and post again if this doesnt work.
The steam is ariving to the steam wand with a thin teflon pipe which is conected to a easy clip on union. So probably by the presure of the steam in the pipe since the capucinatote was gogled the pipe have been came out from the union so the steam is leaking in the machine. Be carefull not work the steam since the water in the machine can make an electrical short and damage the machine completly. Now in order to fix the problem first you must remove the top and side panel in order to connect back the steam pipe to the wand union and second to clean the capucinatore by complitly desasemble it put it in special detergent and leave it fro some our so any dirt will be removed more easily and by a good visual inspection you can see that all holes are cleaned from any dry milk.
Yes you can make a small trick for that. You can use a sqweeter on the milk silicone hose so the milk can flow with more dificalty as long as you can see milk flowing this can be up to 78 C . You should keep the cappuccinatore very clean since you will need the steam to come as easy as possible
Hi There should be a little knob on top of the cappuccinatore. It is what causes the milk to flow up the tube. When it is steaming, rotate the knob slowly until the milk starts to flow up the tube. You can fine tune the knob to get the best foam. If you are missing the pin that has the knob on it, there will be a small hole in the outside top of the cappuccinatore. If you don't have hole and a knob, it is broken off and you need to replace the cappuccinatore
First open it up and run it without any milk attached until just mostly steam is coming thru. Turn off - then drop the tube into a jug of milk which is locted below the outlet. If its steaming, the milk will be heated up ok - it may need flow adjusting - lift the thin 'plug' near the tube up and down to adjust flow. You can add to the froth by lifting the tube out of the milk for a moment then back in again a few times.
To clean the unit just run clean water tru as tho it was milk until it comes out totally clear (about 1/4 cup). For hygiene sake make sure the tube is wiped clean on the outside with a clean paper each and every time when finished.
You can flush your main coffee lines out by making out its doing a large preground coffee - but don't put any preground in.
Select preground - select large coffee and go. Pays also to remove the brew unit and wash in warm water once a week - saves coffee goo building up and causing it to stick.
