EAM3200 grinder only runs for a few seconds and makes weak or no coffee

I have Delonghi EAM3200. It has worked great for +10 years (replaced the heater ~3 years ago) but recently the grinder started running for very short period (~4 sec) even when grind knob is set at max. Any idea what is wrong? I checked the pots on the control board (board on the front with the LED and buttons) and they are working (least they seem to be within the expected tolerances for that type of potentiometer). Is this a Power board issue (board in the back) or is there something else that controls/meters this?

    I amm taking notes of what you say if the grinder is strong with good speed with no burning smell then yes I would thing that it can be the case were the PCB or may be some capacitors had worn out see what the voltage of the grider is if you can run it by its self for about a mint and see if it burns or make smell if all is well oh try and change the thermostat if can give you some good time too.....

    I tried replacing the grinder and the control board (the board with the pots and buttons on it) and it still does not work properly (only grinds for a very short period of time). Is there something else that controls grinder timing?

SOURCE: I have Delonghi ESAM 3300 and grinder runs for

We had excactly the same problem a couple of times recently with a lot of troubleshooting,like adjsusting grinder, reseting the to factory settings, and many more and we end up that it was a problem with pcb control board which lost the preset timing of grinding thus the coffee grinding where about 3-4 sec and the correct one shold be about 8-9 sec. We have here one side which have the control board for your reference.

I have the EAM3200 coffee maker and it seems to be leaking somwhere into the front and back of the drip tray and produces only half a cup of coffee - rest of teh water goes in the drip tray seems to be...

I have the same issue. I have tried replacing the O-rings in the water heating element and the steamer, and it still does this. For a temporary fix, try running the steamer for about 30 seconds, or until it is running "full steam", and immediately make your coffee. This has worked for my machine for the last 4 months. It is used about 5-10 times a day at my work, and this still is working. I believe the issues is it is losing pressure somewhere, and the water cannot travel through the infuser. I have taken apart my machine more than 10 times, and I still cannot find out where the pressure loss is. I know this is a temporary fix, but it will work until something more permanent can be done. Hope this helps!

Weak coffee

since I replaced the O rings on the brew unit I then found the grinder was not producing enough grinds - this resulted in weaker coffee - replaced the grinder with a reconditioned unit from :

Now the machine is as new and the recon grinder has a quieter motor and grinder assembly.
They are great to work with and sell all the parts with instructions and diagrams - now my 10 year old machine is as good as new.

I have the EAM3200 coffee maker and the coffee comes out of the spout very slowly. We have the grinding dial set for course grinding and we have the flavor dial set to weak. The coffee is very strong...

I find the machine needs a good cleaning at least once a month, make sure you remove the filter unit and clean it well, use a damp cloth or paper towel. Mine went like this when I broke a silicone O-ring, it gets lodged in a waterway and partially blocks it. I describe how to replace them in another solution here, take a look.

Grinder is not working If your machine is still under warrenty they will tell you by numbers on the bottom. If you have receipt, even better. They will send you a new machine for shipping costs only. If machine is out of warrenty they will tell you where to get repaired. Very easy to deal with.

Grinder runs with NO beans inside

Fill beans before they run out!
If you hear the grinder running empty, press the same button you pressed to start making coffe to cancel the current cup -or, if some beans were ground, stop the water a bit earlier to make a shorter coffe using the same method (press the button you pressed to start the cup). The auto-detect of beans missing is a very minor and largely useless feature.
