Question about DeLonghi EAM3500 Espresso Machine/Coffee Maker
The machine will not froth milk, and will not produce hot water. Regular espresso making is fine. Have tried multiple descaling and cleaning of both the machine and the milk jug with no improvement.
I understand that the solution was to have the rubber rings on the hot water outlet replaced - but all is rings are complete (green, black and red).
What can I try ?

Here's what I did... with great success:
If you've cleaned all the milk deposits from around the o rings and you still have a problem then its almost certainly the milk spout (the little pipe that directs foamy milk into your cup)
Detatch the spout and get a 2.5 mm drill bit and use it to clean all the milk deposits out of the part that plugs into the lid. Rinse through with water to clean away all the bits of hard milk.
[If you put water through the spout before and after, you will notice a dramatic difference]
Doing this completely fixed the problem for me (I had about 3 years of milk build up in mine!).

If, when you press hot water, the machine says "Heating Up" or "Please Wait" for a moment then returns to "Ready" every time then the horseshoe (steam boiler) is cold. Open the machine and check. Test the thermal fuses (TCOs) on the horseshoe, one will probably be open circuit.
If a TCO (Thermal CutOut, the white ceramic blocks on the horseshoe) is blown, the horseshoe (steam boiler) control triac (usually BTA24-600BW) on the main board is probably breaking down under voltage stress. You will need to replace the main board (or just the triac if you are confident, can upgrade to a BTA24-800) as well as any TCOs that blew. The normal symptom for this is the machine remains in the "Heating Up" state indefinitely, often after having reported "General Alarm" during the event.

I had this problem once... It turns out the electrical connection for the solenoid valve that feeds the hot water out into the milk jug/hot water tap had come loose. They are clipped on rather than being soldered into place. Trace the wires back to the main board from the solenoid (brass bit with grommets) and check that the clips are in place.
