Milk may not be frothed optimally. In these cases simply turn the flow regulator as shown in the figure.
Turn the regulator 2-3 times to perform a quick maintenance.
Note: If the assembled regulator is missing, replace it with the other 3 regulators provided.

Try running 1/5th vinegar and 4/5 water through the frothing device. This will clean out any gunk that might have clogged the interior

The milk tubes should be submersed into water with a milk cleaning agent. sounds like you've left the milk tubes drawing from the fridge with milk in it.
Bean to cup cleaning

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.

Hi
There is a pin on top of the cappuccinator the will twist to create suction. Turn it slowly when steaming until it starts to draw milk up to foam. Then leave it. If you don't have the pin, thats your problem.

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.

check solonoid valve which is located on the group!

Check the cappuccinotore valve, disassemble and clean out the small hole for the milk passage, that may be blocked with milkstone.

You are not supposed to put milk in the resevoir and run it through the machine. That's likely the problem. But like most parents you will continue to blame your child until he is totally alienated and your relationshio is an empty shell.
