When I try to pull a shot, the machine makes a muffled noise, as compared to the distinct "smack, smack, smack", I have heard thousands of times over the past 5 years. The grinder starts and grinds and grinds and grinds... it eventually stops but can't continue with the process as the machine is now full of grounds. I have disassembled the hopper and cleaned the teeth of the grinder. All looks good inside. ANY IDEAS? Should I just buy a new brew group?

Only way to know for sure is by taking it completely apart and expose all the internal parts Popping is not a good sign If it is electrical arcing you are playing with fire or electrocution If you are mechanically inclined they are not that hard to take apart as long as they have no security screws on it and you have to remember you might be voiding your warranty But it is fun taking things apart No?
Likely a foreign object is blocking up the grinder. Remove all beans and
run at coarsest grind to try to clear it, chase it through with more
beans if necessary. If this does not clear it then the top burr of the
grinder assembly can be removed after disassembling the machine. Mark
the grinder coarseness cogs before moving them to assist reassembly.
Moderately difficult procedure.
1, Turn power off at Machine
2, Pull plug out of wall
3, Check and clean out coffee bean dispenser (Checking for jammed bean/object's)
4, Re-assemble coffee dispenser and turn machine on.
5, Try using machine now after yo9u have cleaned and checked for jam's ect..
These machines are tricky and may require returning to Manufacture/Repair shop..
Machine thinks there are no beans because it is not grinding. Most likely the grinder is blocked. The common causes are a small foreign object, a stale hard bean and moisture (either from water spillage or moist beans). The first thing you should do is vacuum ALL the beans out, set it to the coarsest grind setting and run the grinder a few times ( with no beans). Then put a small amount of fresh beans (make sure they are dry and not from fridge or freezer) in and try again. Give it a few goes. If it still wont grind have a good look down there, if it looks wet let it dry out for a while and try again. If none of thes easy tips help you will have to remove the top grinder burr and clean both burrs. Good luck.
Even a properly operating super automatic DeLonghi espresso machine makes enough coffee grinder noise to scare your pets and wake you next door neighbors. It's LOUD, no doubt about it. Only if your grinder makes more noise than that do you have a problem.
Sounds like you have a blockage in you grind passage. Try removing the brew group. Then inside on the roof of the machine where the brew unit was setting there is a drop chute where the coffee is dropped into the brew unit. . From the left side of the drop chute pull down and back, and it will drop coffee. . This will clear an opening that relieves pressure on the passage. There is a passage inside the drop chute area that goes to the grinder. Vacuum it out. It will be on the right side of the drop chute.
Once that is cleared go to the bean hopper. If you have 2 knobs in the bean hopper. Turn the small knob to the minus, (if you don't have one, disregard). Turn the large knob to the largest number. You can turn the knob to a larger number any time but it has to be grinding to turn to a smaller number. Now replace everything and make your coffee. Once you have made your coffee you can turn the knob back to a number that was higher than the one you had it on, but only when the grinder is running.
Try removing all beans from bean holder - then use a vacumn machine to remove the bits down amongst the grinder "teeth'. You may have had a small stone in your coffee and if so it may have jammed the grinder.
Once it looks clean, try making a cup of coffee without the beans in the hopper - you should be able to see and hear the grinder revolving and also hear the brew unit moving between the grinder outlet and the water inlet. If it all seems ok now, then add a small amount of beans back into the beans hopper and try making a coffee. If it still will not work, get it serviced. There's not much the average person can do inside these units other than to do more serious damage or kill themselves with an electric shock.

Not clear on "Empty bean container/full grounds drawer) - not empty/not full. " But I gather that coffee is not being dispensed. Most Likely the grinder needs cleaning + brew group needs cleaning ( filter ). Do you get water/steam?
