Pump won't shut off

Here are some possible reasons why the milk steamer flow is diminished and steam is not coming out of the bottom of the machine:

Clogged steam wand: The steam wand might be clogged with milk residue, which can restrict the flow of steam. Try cleaning the steam wand with a damp cloth or a pipe cleaner.

Faulty steam valve: The steam valve might be faulty or damaged, which can cause a decrease in steam pressure. In this case, you may need to replace the valve.

Blocked milk frother: The milk frother might be blocked with milk residue, which can prevent the milk from frothing properly. Try cleaning the milk frother with a damp cloth or a pipe cleaner.

Faulty milk frother: The milk frother might be faulty or damaged, which can cause a decrease in milk flow and prevent proper frothing. In this case, you may need to replace the milk frother.

If none of these solutions work, it's best to contact DeLonghi's customer service for further assistance

1. That is the right milk. Use a thermometer with the milk.
2. The middle button is used for steam. It engages the high themostat for steam.
   1. Slightly open the steam valve
   2. Turn on the middle button
   3. Keep the end of the steam wand slightly above the milk surface (0.5 mm) so the steam incorporates air into the milk. (Takes practice)
   4. Open the steam valve as the boiler heats up. (Takes practice)
   5. When the milk get to 74 C (165 F) immerse the steam wand into the milk and heat to 82 C (185 F)
   6. Turn off the middle button and shut the valve.
3. For 90 ml of coffee, use 14 gram of ground coffee. The coffee scoop that came with the machine holds 7 grams of ground coffee as it comes out of a grinder (not packed). Tamp the coffee after it is in the sieve.

i'll preface this by saying i have never used a strarbux machine, but I have used dozens of others (daily habit for 18 years now)

when are you trying to get your steam (ie before or after brewing the espresso)
If you have been trying before, wait till after (if your machine does not let you turn off the espresso output then when the coffee starts to slow down (just past the peak of flow).
It should take only a few seconds to steam the milk. (also the closer to the surface of the milk that the steam is released the frothier the milk will get)

Run the hot water cycle for a few seconds to prime machine.

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

Do not push steam nozzle to much on the dispenser. Just pull it back 1mm or something. If pushed to the end there is no ejection and milk is not extraced fro the canister.

a. Possible air in the system. Switch to hot water iso steam, let warm water pas for a minute by turning the knob fully open. Stop tapping warm water (close the knob) and switch the machine to steam iso water. Try to get the steam by fully opening the knob (pump should start running). 
b. Solidified milk in the system blocking internal tubes. To avoid this always purge the system (shortly open the steam to an empty cup or a towel) after you steamed milk to avoid milk being sucked back into the system due to condensation of steam (this creates a vacuum and reverse flow). To resolve the blocked tubing: clean the nozzle and try flushing the system (tapping warm water). 

please relay on your experience realizing that you now have new steam pipe(with different holes in the end of it and different pressure)
you will need to get use to them and get maximum quality of that steam pipe.
my advice:

1. every time hold your hand in the bottom of milk container, so that you will prevent overheating which often gives the result you mentioned.
2. every time you use cold milk.
   

Typically it give the ventilate because insufficient amount of water/steam is comming through. A clog in one of the lines is usually the problem. This causes all kinds of headaches. There is nothing you can do so I suggest you do a search for an Authorized Saeco reapir center and have them do a service on it.
