2" thick, plus there is spill over of grounds. At a normal grind setting, water will not pass through the extra thick puck. Changing to a courser grind lets water pass through, but its way to strong. This is the same at all strength settings (strong, normal and mild) What is causing the grinder to run to long?

The amount of coffee grounded is also propotional to the thickenss of grinds and the time. So when you udjust the grinding more fine then with the same grinding time the grounded coffee will be reduced. So if the grinding have changed to more coarse grindig that is why the quantity have increased.
Now their is a small posibility that the standard grinding timing to be increased but this can not be fixed since this is prefixed from the factory on the electronic board thus you will need a new electronic board.Of course the increse in time is due to only a tiny electronic part on the board called variable resistance you will need to replace the whole board to be fixed.
Therefore you can try to reduce the grinding step by step to more fine to see the results nad this might work bu 70%. However the coffee running time should by aprox 1 sec for one ml of coffee. So for one espresso of 30 ml then it should take about 30 sec to run.
There is a page with some parts but from what we can see there is not any cpu board.
So we sugest to go throught the contact page and make your inquiry or even call the directly.
delonghi have not many options for direct online replacing parts like saeco or similar which you can find at partsguru.com.

Steel ball bearings might take 30 seconds to grind - no coffee bean takes so long.
