    Remove the o rings where the milk frother connects to, there is a green, red and black rubber O ring. Remove them and get a toothpick and clean around where they sit. You will notice a hard milk build up like when you get on your teeth. This is what may be causing your problem the o-rings are not setting their properly. Also, the O Rings might be worn out, replace them.

    No water comes out of the milk frother, machine makes no noise when you try to make a capacino. Capacino button just doesn't work. Have consulted manual and the manual doesn't offer any solution.

The frother does not have a vacuum, it uses venturi pressure to draw up milk through a venturi at the top of the steam feed. The milk side is clogged from not cleaning enough. soak in boiling water for a few minutes and try to run it in steam mode for a while... if that doesnt work, a light lye solution will dissolve the milk residue clogging it. neutralize the lye with vinegar drawn through after the clog is gone.

(lye will dissolve you as well as milk... use gloves and don't put your face near it while it's working.)

Hi, We have a Saeco Royal coffee machine and the milk frother doesn't seem to be working. Need some advice as to what could be the problem?

1- Royal Coffee is not an accurate model. I have to assume that you are having problem with the auto frother that is on the left side of the machine. The auto frother draws milk from the bottle and steams it into the cup.
2- The connection of the frother & the adapter is not right/air tight. The two O-rings on the frother must be pushed in all the way so the O-ring will not be visible.
3- The frother circular chamber for steaming is not clean. There should be no milk deposits visible at all.

4- The silicone tube puling milk from the bottle is connected to the body of the frother with an L-shaped connector. Make sure this connector is air tight fit.

Why does milk frother blow out steam instead of milk?

That is what it is supposed to do. Take cold milk in a cup, and put the frother wand in it... Kind of bob it up and down for a few seconds, and the milk will froth.

DeLonghi Perfecta ESAM5500 when trying to make a cappucino it wont **** up the milk any ideas thanks

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.

Our PrimaDonna coffee machine doesnt appear to be takeing in any milk from the jug to make latte's or cappuciono's, is there any way of sorting this out ?

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.
