Question about DeLonghi Magnifica 3300 Espresso Machine
I have a DeLonghi Magnifica coffee/expresso centre that is now spilling grounds over and outside of the inner basket. When I remove tray I find grounds all through the inside of the machine, including both sides of the infuser. I have cleaned all areas of the inside; removing and cleaning the infuser, brushing out the inside and using a pick/brush to clean all small areas. This has not helped.What am I missing?

i had this problem, and have now finally figured it out and fixed it. the problem is that there is a solenoid valve sticking. i believe that the valve is used to relieve pressure after using the steam, and it vents the hot water directly to the tray. if you aren't diligent about descaling, or if there are water impurities, or if you use the machine infrequently, or for probably any number of other reasons, the valve can gum up and stick in the "open" position, continuously draining the water directly to the tray.
one easy way i've got my machine to work was to cycle steam on and off a few times, thereby signaling the valve to open/close, and unsticking the valve. you can see if it worked without wasting coffee by initiating a rinse cycle, and seeing if the water correctly comes out of the coffee nozzles.
if that doesn't work, you can disassemble the machine and tap on the valve. it has a square black solenoid ~1" square on top of a brass valve. it is mounted on the same bracket as the u-shaped heater. a few sharp raps on top may free up the valve.
if that doesn't work, remove the valve, and try to blow through it. if the valve is stuck open, air will go right through. hold the valve upright and tap it onto a hard surface (countertop, floor, etc.) try blowing through it again. when the valve is unstuck (and held in its normal operating position), you will not be able to blow through it.
once the valve is unstuck, run your machine through a descale process. that should take care of it.

on my machine, the two screws that attach the infuser receptacle to the insides of the machine came loose. You can see those two stainless hex socket screws when you remove the infuser by grabbing its two red tabs and pulling it out. Just use a hex shaft
screwdriver (size 3mm or thereabout) to tighten them.

Remove base plate and turn pulley clockwise (probably for several minutes) until infuser arm returns to vertical position and the infuser itself drops to the low position. You should here a click when it reaches this point. The infuser can then be removed as normal.

Have you ever wondered, 'how do I descale my
expresso machine?' First lets us understand what is exactly is scaling.
The build up of minerals inside the hot parts of your coffee machine or
espresso machine is commonly called lime scale. When lime scale
builds up inside the Espresso machine, it slows down the water flow,
reduces the boiler capacity and can prevent your coffee machine from
working properly. To keep your Espresso machine operational at full
order, it is important to descale it every three months. The time
intervals between descaling depend upon many factors. Quality of your
water and the amount of water running through the machine are the two
main factors that decide the frequency at which you should descale your
Espresso machine. The more you your machine, more often should you
descale it. In some cities, in conjunction with a water filter you can
use your coffee machine for a year or more without descaling at all. If
you use less water by drinking espressos you'll need to descale less
often than if you make cappuccinos.
Descaling products are widely available from stores
that sell coffeemakers and espresso machines. Be sure that the product
you buy to descale your Espresso machine is intended for this specific
use only. Before you descale your Espresso machine, always unplug it and
make sure that it is cold. Also, never immerse the appliance in water
and nor should you use abrasive cleaning products
or scouring materials on any part of your Expresso machine. In case
your Espresso machine does not come with a instruction guide or booklet,
then use a proper citric acid based descaling solution designed for
espresso machines. This should be mixed and prepared as per the
instructions on the bottle or packet. Once your Espresso machine has
been descaled properly you would not be left wondering, 'how do I
descale my expresso machine?', treat yourself to a great cup of coffee.
