Question about DeLonghi EAM3500 Espresso Machine/Coffee Maker

1 Answer

Grinder runs with NO beans inside

I've had the EAM-3500 for few months and it has been working ok until now.
Normally when I press a button to make a coffee, the grinder goes on for about 4-6 seconds, grinds the beans then start the whole process.
When there is not enough beans and we make a coffee, the grinder goes on for few seconds and display a message "to add more beans".
Now the grinder goes on for 30 to 40 seconds (even if there are no beans) than make the coffee.
I have suspected that the bean sensor was defective, so I contacted the MFG to get the service manual or electrical diagram, and they responded to me an gave me a phone number to call in CA, I call them and they sent me a copy of the Diagram & Diagnostic manual.I looked everywhere and can not find a bean sensor, I did a factory reset and it did not help.
Any help will be appreciatted.

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.

Why fill bean message shows on display when machine is full of beans?


Difficult to say without the machine in front of me. Normally you get this response if no beans fall into the grinder. Are your beans oily, sticking together and not falling in?
Normally freshly roasted beans esp dark roasts are a bit oily. If so then you can change roasts, brands or mix with another type.
You might try to adjust your grind per the manual. (turn knob inside the bin while the grinder is grinding) see #8 page 12.
If the beans are falling in and grinding and you still get this msg I would say you have a grinder problem.

How do i change grinder setting while its running


I don't believe you can. There is a switch that turns off the grinder if you remove the lid to the bean hopper. The grinder adjustment is under that lid...so, unless you bypass the switch in the lid (which can be done) you cannot get access to the grinder adjustment.

I keep getting "Fill Coffee Bin" when the bin is


Sounds like the grinder is blocked. Set the grinder to the coarsest setting (largest number) and try a few more times. If still no luck then vacuum out all the beans, run the grinder again a couple of times and then add a small amount of fresh beans (not from a fridge or freezer as these will be moist and can cause problems) and try making coffee again. If after a few tries it still doesn't work then you will either have to remove the top grinder burr and clean both burrs (not recommended unless you are bit of a handy person) or you could try vacuuming out the beans again and letting the grinder dry out for a while (although unlikely, it could be wet from water spillage). Good luck hope this helps.

Attemps to gind but no beans seem to get through Then the display indicates 'add beans' although it is full


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.

Machine says beans are empty and will not brew.


Try adjusting the grinder coarser when it is running. Either the grind is too fine or the grinds chamber is blocked, remove the brew unit and check the gate to the grinder on the inside right.

Ground coffee will not dispense


The beans are hanging up in the hopper and not falling down into the grinder...... wiggle it, give the beans a push, or go to a bean that is not so sticky....

Jura E9 grinder spins but does not grind


I had a similar problem, and solved it by turning the grinder by hand against resistance. Apparently the grinder wasn't really turning during the cycle and needed to be cleared. If your beans are "hopping" this may be a different problem.

How do I remove the burr grinder for cleaning? Saeco Royal Exclusive


This is not a hard procedure, but you have to feel comfortable with DIY projects.
First empty the bean container. Vacuum out any remaining beans. Remove the philips screws from the hopper. Lift the hopper off. Vacuum any loose beans out. Remove the rubber gasket. You may clean this with a mild soap solution. Remove the grind adjustment lever- lift straight up with index fingers under the flange. Turn the outer ring with the holes counterclockwise, lift the center ring with the ears straight up when the outer ring is loose enough. The ring with the ears is the upper burr. Clean with a brush. Don't use water or other solutions. Vacuum the beans chamber and brush clean. Replace the upper burr ring matching the ears with the grooves. Turn the outer ring clockwise until it stops. Pull the inner ring to be sure it is locked. Now turn the outer ring back 13 clicks. Replace the rubber gasket. Replace the grinder adjustment lever- drop the lever flange inside on the outer ring with the lever grip loop over the top at #4. Press the flange with two fingers while supporting the outer ring from below. This seems tricky, but be patient. Replace the hopper and screws. Do any grinder adjustments while grinder is running with beans, it may take a few shots to be back at your preference grind! Good luck!
