Question about Krups Burr Coffee Grinder

Open Question

Blue light goes on, but the grinder stays off.

After grinding some beans, the grinder wouldn't go back on. I cleaned the machine and tried it again but to no avail. The blue light goes on but the motor doesn't.

Any suggestions?

    Ditto - at first the motor sounded funny, so turned it off, shook it around to try and loosen the beans. When I turned it, the light came on and no sounds came out.

Sound like it's choked up with grounds and oil. Burrs may also be blunt. U need to dismantle and clean/ check burrs, passages and body. If you can see "flats" on the burrs or they feel not sharp when you check with finger, they should be replaced.

I had the same problem, took it all apart, separated the two halves, and looked into the guts of the machine, not an easy task. Fiddled with this and that, and looked at the back of the switch mechanism, and heard it making a 'click' when depressed, so put it all back together, to no avail...It turns out the grinder needs to have two limit switches engaged, one between the lid of the ground coffee hopper and the underside of the grinder hopper housing, and the other between the grinder lid and the base of the unit. This last limit switch was my problem, it seems the lid wasn't making contact with the limit switch, so the unit didn't run. I cleaned out the narrow gap that the grinder lid sits within, pressed the lid down until I heard a small 'click' , pressed the on switch, and presto! it works. You can see this very tiny switch if you take off the grinder lid, and look in the narrow gap it sits in at a position of about three o'clock ( the back of the machine when viewed from the top being 12 o'clock. Hope this helps anyone else who can't find their receipt within the one year warranty period. This is the best burr grinder I've found for the money, and I'm glad mine's still o.k.

After reading the first two solutions, and confirming that the two switches referred to weren't the cause of the grinder no longer operating, the following brought our grinder back to working order; 'unlocking' the grinder part (and removing it), pouring water through, and poking a paper-clip into the opening which feeds the container for the grounds.

Check all connections and plug then after that it is a short behind the switch and will need to be sent back to the manufacturer.

HOW DO I CHANGE THE GRINDING MECHANISM ON MY SPIDEM TREVI EXCLUSSIVE ESPRESSO MACHINE. I HEAR THE MACHINE GRINDING BUT IT'S REALLY NOT DOING ANYTHING. ANY SUGGESTIONS


When the grinder spins free and fast it only means that fresh beans are not feeding into the burrs. This happens when:
1- Grind setting is too fine and beans cannot enter the grinder mechanism.
2- Use of oily dark roast beans can clog the ground coffee chamber and preven the fresh beans entering the grinder.
3- The ground coffee chamber outlet is clogged due to oily beans or too fine coffee setting.

When you cleaned the grinder you may not have cleaned the coffee outlet to the doser on the left. You can clean the outlet to open the passage of coffee grounds to collect in the dosing device..
After cleaning the outlet, you should next make sure that coffee grounds are not packed in the doser. The doser is inside the door right above the brew group.
To access the doser:
1- Remove water tank.
2- Remove the brew group.
3- Lay the machine on its back for full view of the doser.
4- Pull the doser door open (it is like an Attic door.
5- Keep the doser door open and clean the inside with a brush. The outlet from the grinder is on the right side with a wire wiper cleaner that moves across the grinder outlet fills from the grinder. This opening.
Use a brush to clean the doser.
On the left of the doser space there is a plastic flap that is pushed to the left when coffee grounds fill the doser.
At certain distance push back (1/4") the notch on top of the flap pushes the doser micro switch pin to stop the grinder. Push the flap gently to the left to make sure that it is moving well. With each push back of the flap, one can hear the feeble click sound from the micro switch.
When the above cleaning is done, try the grinding.
If the conical burrs have not been replaced for over 2500 grinds, it is time to do so.

The above grinder and grinder doser cleaning instructions are available as download files on the following page link:

One can find many useful maintenance guides on one page.
Good luck.

Our Saeco Vienna Superautomatica sounds like it's grinding beans but keeps running until the red 'bean' light comes on and we have to shut the machine off. Any suggestions?


The grinder is timing out and stops if the beans do not enter the grinder. This happens because:
1- The grinder outlet is clogged and fresh beans cannot pass through the burrs.
2- The grind setting is too fine and helping clogging in the grinding chamber or the ground coffee outlet.
3- Operator may have been using dark roast oily beans. Like it or not, the dark roast oily beans do not make stronger espresso. Please stop using such beans in fully automatic espresso machines.
4- The grinder has already made over 2000 grinds and the burrs are blunted and not grinding beans as needed.
To solve this malfunction, clean the grinder. Make sure the grinder outlet to the doser is cleaned. This outlet passage is about 2 inches or more. To clean it, lay the machine on its back (water tank side) to allow better view of cleaning the doser and the passage of coffee from the grinder to the doser. Use the link below to find instructions for cleaning the grinder and replace the burrs.

How to fix, "no bean light" stays on?


hi there,
have you also cleaned the output of the grinder and the doser?
You have to open it (carefully) by hand, as it is normally closed and only opens when the actuator is switched on, and clean the inside with a soft brush.

After cleaning the grinder, its outlet and the doser, the machine will have to gring at least twice ti fill-in these parts, each time saying that there are no beans. It should be OK with the 2nd our 3rd cycle of grinding.

Hope that helps,
M.

Fill beans


the coffee beans are not entering in the grinder disks and since they rotate without coffee the machine understands that their is no beans. You need to clean the grinder disk and grinding coffee funel to bee sure their nothing blocking the coffee movements. Use a vaccum cleaner and try to clean everything in grinder and grinder exits. Try also the machine by regulating thegriding to more gross coffee and when it will start grinding normal then you can udjust step by step back to grinding position you have at the begeining.

The grinder grinds too long, then stops and then the bean refill light goes on, ---there are plenty of beans but no coffee being made. I think the grinder is not working somehow. Its a 5 year old Saeco...


The lever under the bean hopper is set to low. Push it all the way to the back.
There is a leverbehind the door in the middle top. Pull it to the minus and try again.
If that doesn't work you are going to have to take the grinder apart and clean it.

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.

Saeco Vienna grinding issue


Hi,

I think so, most problem with that the grinder grind to the lamp light up is damp in the grinder or oily beans.

if you have two adjustment knob in the bean hopper then the second problems can be the micro switch in the machine that have to be replaced.

Saeco Incanto Classic - Bean feed problem


Hi,

First, make sure you not get any damp into your grinder.
If you get damp into the grinder then it will not grind the beans.

To check the grinder you have to loosen the three screws in the beanhopper and lift it up.
The jagged plastic in the machine you will see when the beanhopper is off, turn it anticlockwise to you can see
the claque is free, then you can take out the jagged plastic and you will see the grinding wheel, make sure the wheel and the jagged plastic is clean.

Before you mount all again, use a vacuum cleaner to clean it.

Put back the jagged plastic again and turn it clockwise to it stop, then you turn it anti clockwise 14"click".
Set the number to 8 on the beanhopper and mount it again.

Hope this will help you.

Best regards
