Pump for the Milk Steamer is pumping permanent

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

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.

I've also had this problem with the Krups 'Il Primo' - reduced steam for frothing of milk but plenty of espresso.
Diagnosis: over many uses, a residue of dried milk plugs the interior of the steamer tip.
Fix: Using a small adjustable wrench, remove the tip. Clean it inside and out with a tooth pick. Reattach the tip - gentle with the wrench.

My only non professional suggestion is to take off the rubber cover on the steamer and make sure that and the metal steamer itself is clean.

Straighten a paperclip and stick it into the steamer wand. You probably have dried milk gunk in the nozzle. After you've cleared it and it's working again, be sure to blow a puff of steam out after each use to clear collected milk in the nozzle.

Does not seem normal! You should get plenty of steam for the frothing. Since the unit is new you should take it back and get a replacement. The unit needs to increase the temperature for steam, route the steam away from the espresso group to the steam unit and the pump needs to activate to create the high pressure. Any failure in this areas will create your condition. It also possible that your steamer is blocked but this is a new machine so this is unlikely but you should make sure that it is not blocked.

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). 

if you could remove the pipe put the pipe in a solution to remove the calcium in thr pipe dry calcium is like concrete dip it and use a piece of wire to clean cheers

Try opening the frothing valve by turning the dial and force water through it instead of steam by pressing the middle, coffee button. You may be experiencing vapor lock. Once the water comes through the steamer valve, turn the steamer knob off and release the coffee button. Then try the steamer button with the steamer dial open. This may do the trick.
