Question about DeLonghi EAM3400 Espresso Machine

1 Answer

My Delonghi EAM3400 is no longer steaming the milk properly. the unit sounds like it is working really hard to do any steaming at all. what little steaming it does accomplish, the milk is not hot. i have cleaned the unit inside, cleaned and replaced the diffuser and have descaled. no change in steam issue.

    I'm having the same issue. I've pulled the machine apart (a few times now) and the answer looks to be at the bottom of the generator. The cap at the bottom below the O-Ring that pumps water through the coffee, leaks while the machine is trying to pump steam.

    I tried cleaning out the steam pipe & also replaced the O-Ring on the generator, but the same problem exists. Can anyone help?

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.

My Delonghi Prima Donna won't dispense milk only steam.

I've just had the same thing happen to me today. The one thing I noticed was there is a broken rubber ring which appears to have fallen from around the milk spout.

I'm off to the Service Centre tomorrow so will hopefully have some good news shortly...
