Coffee Grinder on the EAM3500

Here are some specific steps you can take to try to repair the grinder issue with your Miele CVA 4085 coffee machine:

1. Clean the grinder: Remove any coffee grounds that may have accumulated in the grinder mechanism, and clean it thoroughly with a brush or cloth.
2. Check the grind burrs: Inspect the grind burrs for any signs of wear or damage, such as chips or cracks. If they are worn, they may need to be replaced.
3. Adjust the grind setting: Make sure that the grind setting is adjusted correctly for your type of coffee beans. If it is set too fine, the grinder may struggle to process the beans.
4. Check the grinder motor: Make sure that the grinder motor is functioning properly and that it is not overheating. If it is making a strange noise or if it seems to be struggling to turn, it may need to be repaired or replaced.
5. Reassemble the grinder: Make sure that the grinder mechanism is properly assembled and that all components are securely fastened.

If these steps do not resolve the issue, it may be necessary to have a professional service the machine.

It seems there's a fault in the grinder gearing in this particular model.There's no solution but to take it to Breville repair...
I have the same problem and so does a friend of mine. The grinder will spin without beans in the hopper but as soon as beans are introduced the grinder makes a loud noise. Like the gears are slipping and there's not enough power to grind.

Sound like the shaft broke, or a gear stripped.

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.

It is not a healty sound,seems either the gear cogs slipped or the plastic base that holds the lower blade of the grinder is broken.

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.

First turn grinder to coarse setting and try grinding some white rice through it, that will clean out the coffee oils, if that does not work then the you will have to open the grinder and clean out the burr chamber and the spout for the grounds.

the grinding itself makes noise. if you have noise in empty spinning than you should consider changing bearings( 2 of them) in the motor.
during opening grinder pay attention to lower holder of burr which spins together with axis, try to be gentle with that part.

Since your grinder makes noise and the problem occured suddenly, I would rule out a grinder problem. I am guessing that your grinder runs 10-20 seconds before it stops. If that is the case you need to look for a obstruction in the grinder or a failed microswitch on the doser. Either of these could cause the problem.

1. take out bean container
2. disassemble 3 philips screws and take plastic out
3. rotate the knob to try to get out the upper holder of burr. if it does not rotate than disasemble the knob and the gears(plastic big one is attached to upper holder of grinder, the other is together with knob.
4. tru to rotate it manualy, with help of extra srews puted in gear holder holes.
5. when you get it out, carefuly clean it, look for metal parts and stones(wich sometime comes with coffee)

1. turn on the grinder and attach gently one marker to lower burr during spining. after you stop grinder, look if it is perfect circle marked in burr. if it is not than marked side is higher. you should consider getting it ok by putting adhesive paper under lower burr and check it again.

good luck and carefuly.
