Delonghi Magnifica coffee maker grinder and infuser problems

Last Updated on October 2, 2023 by Pablo Barrantes

Selecting the right coffee beans when using our Delonghi Magnifica coffee maker can prevent future problems with the grinder and infuser. And by “right beans,” I mean those with a light roast.

Unfortunately, this importance often goes unnoticed until our Magnifica shows signs of malfunction. Many users encounter the sudden stop of their coffee maker’s grinding function, either after a period of inactivity or suddenly for no apparent reason.

Similarly, there are cases in which the coffee maker interrupts the coffee brewing process, almost as if it lacks the power to extract the coffee. On a positive note, most situations can be resolved with simple remedies.

Delonghi Magnifica coffee maker grinder issues

Issue 1: Poor coffee grinding performance

Problem: The DeLonghi Magnifica coffee machine consistently produces poorly ground coffee, regardless of adjustments made to the amount of coffee or the grinding level.

Cause: This issue stems from using overly darkly roasted coffee beans, excessively oily, or even containing added sugars during roasting. These elements adhere to the grinder’s burrs, forming a tough layer that coats the cutting edges.

Solution:

• Disassemble the side panels of the brewer and disconnect the black wires leading from the grinder to the control board. Photograph the wire connections for reference.

• Use a wooden tool (never metal) to clean the coffee outlet funnel. Sometimes, humidity can cause the funnel to become clogged with hardened coffee.

• Clean loose coffee grounds around the burrs and identify where the coffee has solidified. It may be lodged between the burrs or the ground coffee outlet funnel. If the grinder is clogged, follow these steps to remove the burrs to clean them with soap and water.
• Remove the bean hopper screws to gain full access to the grinder and remove it from the machine.

Note: Once you have removed the tova, you must be very careful when handling the grinder, paying special attention to the bearings of the grinding degree selector wheel mechanism.

• Turn the grinding selector all the way to the end as you see in the picture below. At this point you can remove the outer grinding wheel by pulling it upwards.

• Unscrew the upper Torx screw by turning it clockwise to loosen it.
• Carefully remove the center cutter, ensuring not to lose the three bearings and springs attached to the base. Take photos to facilitate reassembly.

• Clean all parts with the wooden tool to remove coffee residue.
• Wash the burrs with soap and water to remove coffee oils.
• Dry all components thoroughly, reassemble the grinder, reconnect the power cables, fix the hopper, and replace the side panels.

Issue 2: Inoperative grinder

Problem: The coffee machine’s grinder does not function; it neither turns nor produces sound.

Cause: This problem is likely an aggravated version of the previous issue, where coffee blockage prevents the grinder from operating successfully. This strain can lead to motor damage.

Solution:

• Follow the steps outlined in “Issue 1” to address the problem.
• If, even after a thorough cleaning, the grinder remains nonfunctional (no movement or sound), you will need to acquire a replacement grinder.
• Consider searching for spare parts on various platforms, including the ones provided below, as well as Facebook Marketplace and other second-hand product pages. You might find a replacement DeLonghi Magnifica grinder for as little as $30 to $40.

Delonghi Magnifica coffee pouring issues

Problem: The DeLonghi Magnifica coffee maker is not dispensing enough ground coffee for the preparation. The grind level doesn’t appear optimal, as the coffee barely comes out, and if we increase the grind’s coarseness, the coffee is extracted weakly.

Cause: In this case, the problem isn’t directly related to the grinder but to the infuser. Accumulated residues and dirt inside the infuser can lead to blockages, preventing the water from flowing properly through the ground coffee.

Solution:

• Open the front cover of the brewer and carefully remove both the trays and the brewer. The brewer can be removed by pressing the two red side wings and pulling them towards you.
• Disassemble the brewer until you can access the inner piston. To do this, you must remove a plastic flange from the bottom and then pull the piston out from the top while removing a black piece from the bottom.

• Remove the filter screen at the piston’s end; a Phillips screwdriver is all you need to remove it.
• Thoroughly clean this metal filter before replacing it in its original position. It will be completely clean when you can see the light through its perforations by holding it up to the light.

• Once you have completely cleaned the metal filter, you must ensure that the valve at the top of the piston moves freely. If this valve does not work, the coffee maker will not brew coffee, and you will have to buy a new brewing group.

• Carefully remove the O-rings, clean them thoroughly, and replace them, removing any residue. If you notice any damaged or worn gaskets, replace them with new ones in good condition.

• Once the components are completely clean, apply food-grade grease to the O-rings and piston body with your finger. The piston should move smoothly up and down without resistance.

• Reassemble the piston in the infuser. Check that the piston moves smoothly and that the grease has been evenly distributed. Test the movement by raising and lowering the piston until you know its operation.
• With the piston correctly assembled, return the infuser and trays to their respective positions inside the brewer.

By following these steps, you should address the pouring issues you were experiencing with your DeLonghi Magnifica coffee machine. This maintenance procedure will help ensure the optimal functioning of the infuser and improve the consistency of your coffee grounds.

Delonghi Magnifica coffee maker infuser stuck

DeLonghi bean-to-cup coffee makers automate dosing, tamping, and extraction through an internal infuser or brew unit. When this component becomes stuck in the wrong position and ceases to function, it can lead to operational issues.

Problem: After each coffee brewing cycle, the Delonghi Magnifica prepares for the next brewing process by placing the brewer in its lowest position. However, there are occasions when the brewer locks in its highest position.

Cause: If, for any reason, the power supply to the coffee maker is interrupted during the automatic reset procedure, the infuser might not return to the lowest position and instead becomes stuck in an unintended location.

Solution:

1. Start by turning off the coffee maker and unplugging it.
2. Ensure the service door is closed, and the water tank is securely in place.
3. Connect the coffee maker to the power source and turn the coffee machine´s switch on.
4. Once the coffee maker is powered on, allow it to attempt an automatic reset. Then, turn off the machine and wait until the process is fully completed, as indicated by the lights turning off.
5. After this sequence, the infuser should be in its correct position. If needed, you can now safely remove it.

By following these steps, you should be able to resolve the issue of the infuser getting stuck in your Delonghi Magnifica coffee maker.
