Common reasons a Delonghi La Specialista stops pumping water?

The order listed by the original poster is basically the order I use and most other people I’ve seen doing these repairs. Nobody works on these machines without first checking the tank seating.
 
The flowmeter is the most common issue on these machines. I’ve done about a dozen La Specialista machines in the last 2 years. Half had the flowmeter issue then the solenoid and scale getting half the machines to the point where the pump will fail. The rest were actual pump failures or dumb issues with the tank seating.

same here. Actual dead pumps are rare.
 
For these machines the reset is to hold the two buttons for 5 seconds. It beeps and that’s it. Costs nothing to try and works occasionally to fix pump issues.
 
if the machine makes the sound of the pump but there is no water coming out do not continue to run the machine. This will burn out the pump and you will have to get a new one. A maximum of 30 seconds without water to run the machine.
 
This is why I will never buy another coffee machine with a flowmeter. E61 lever group machines, go manual. Nothing to fail. My take on these machines is they will last me a lifetime but my La Specialista will outlive me.
 
one more thing that has worked for me; sometimes the little check valve in the pump head gets stuck on these machines. Try tapping the pump body with a screwdriver handle while the machine is trying to pump water. Sometimes this will free up the check valve.

The tap trick works more than it should. I’ve fixed 20% of the pumps that are “dead” with this trick and a descaling; by far the most common issue. Ulka pumps are just a piston and spring, usually get stuck rather than broken.
