Fix Your DeLonghi Magnifica Not Grinding – Quick & Easy Guide

DeLonghi Troubleshooting Nov 30, 2023 No Comments

If your DeLonghi Magnifica coffee machine is not grinding the coffee beans, there are a few troubleshooting steps you can take to fix the issue.

In this guide, I will provide you with a step-by-step process to resolve the problem and restore the efficiency of your coffee machine.

Why DeLonghi Magnifica Grinders Stop Working

The number one reason grinders in super-automatic coffee machines stop working is because of clogging issues or a small hard object falling into the grinder by mistake.

– If you notice that the grinder is extremely loud and NOT grinding coffee at all, this is a burr issue.

– If you notice that your DeLonghi is making weak coffee shots, it’s most likely a clogged grinder or chute. (you can test this by making coffee using pre-ground coffee and checking if it’s brewing correctly)

Common Issues with DeLonghi Magnifica Grinder

The DeLonghi Magnifica grinder may encounter a few common issues that can prevent it from grinding coffee beans properly. Understanding these issues can help you troubleshoot and resolve the problem effectively. Some of the common problems include:

  1. Strange noises coming from the grinder: Unusual noises can indicate a problem with the grinder motor or burrs. It could be caused by worn-out components or debris stuck in the grinder. Noise always indicates that there is a blockage in the grinder.
  2. Clogged grinder: A clogged grinder can result in inconsistent grinding or the complete inability to grind coffee. This can occur due to a buildup of coffee grounds or other debris in the grinder. Fixing this issue is as simple as cleaning the burrs.

If Your Grinder Is Making a Loud Noise

If you hear grinding sounds that are not consistent with the normal operation of the grinder, it could be due to worn-out burrs or a malfunctioning motor.

Fixing this issue requires dissembling the coffee machine to take out the burrs for inspection. If you are not a handy person, I advise that you send your machine for professional repair. But if you don’t mind taking your machine apart and trying to fix it yourself, keep reading for instructions.

If Your Grinder Is Working, But Making Less Coffee or Inconsistent Grind

This is an indication that your grinder is clogged. This happens especially if you use oily dark beans and don’t clean the grinder as much as you should.

Oily beans are not recommended for super-automatic coffee machines. While they are fine to use, they tend to clog the grinder easily because they stick to the burrs. This, in turn, requires that you clean your grinder more often, which many users fail to do.

To clean the grinder, you will need to remove the beans and the hopper and clean out any leftover coffee grounds or debris.

It is important to avoid using water to clean the grinder, as this can damage the machine. Only use a dry cloth or vacuum to clean the grinder components.

Steps to Clean the Grinder

  1. Turn off and unplug the DeLonghi super-automatic coffee machine.
  2. Remove the bean hopper and empty any remaining coffee beans into a container.
  3. Use a dry cloth or vacuum to clean out any coffee grounds or debris from the grinder chamber.
  4. Inspect the grinder burrs for any signs of damage or wear.
  5. If necessary, gently brush the grinder burrs to remove any residual particles.
  6. Wipe down the inside of the grinder with a dry cloth to remove any remaining debris.
  7. Reassemble the grinder components and ensure they are properly aligned.

Once the grinder is cleaned and reassembled, you can test it by making a cup of espresso. If the DeLonghi Magnifica grinder still does not grind properly, you may need to explore other troubleshooting options or contact the manufacturer for further assistance.

Using a Vacuum To Clean The Grinder

This sounds like a weird cleaning tool for a coffee machine, but this is actually recommended by DeLonghi.

Using the vacuum with the nozzle attachment helps you get suction inside the grinder burrs and chute without the need for dissembling your machine.

If you’re not comfortable using your house vacuum, buying a cheap small handheld vacuum for this specific task would be a great idea.

As for brushing the grinder, you can use any soft brush, like a toothbrush for example, to get the job done.

Checking the Grinder Burrs for Damage

If your Magnifica coffee machine is still not grinding the coffee beans properly after cleaning the grinder, the issue may lie with the grinder burrs.

The burrs are responsible for grinding the beans to the desired consistency, and if they are worn out, misaligned or something is stuck in it, it can affect the grinding process.

To check the grinder burrs, you will need to access the grinder mechanism. Inspect the burrs for any signs of damage, such as chips or dullness. If the burrs are damaged, they will need to be replaced with new ones.

Ensure that the burrs are properly aligned before reassembling the grinder. Misaligned burrs can lead to uneven grinding and inconsistent coffee grounds. Once the burrs are aligned and securely in place, test the grinder by running a small amount of coffee beans through it.

If you are not confident that you can take the machine apart and then reassemble it, please send the machine for professional help instead to avoid permanent damage to your machine.

Troubleshooting the Grinder Adjustment Ring

The adjustment ring controls the coarseness or fineness of the coffee grounds, so if it becomes disengaged or stuck, it can affect the grinding process. Follow these steps to troubleshoot and fix the issue:

  1. Inspect the adjustment ring: Start by checking the adjustment ring to ensure it is properly engaged with the grinder. Look for any signs of damage or misalignment.
  2. Reposition the adjustment ring: If the adjustment ring is disengaged or stuck, follow the manufacturer’s instructions to reposition it and secure it in place. Make sure it is properly aligned with the grinder.
  3. Test the grinder: After repositioning the adjustment ring, test the grinder by grinding a small amount of coffee beans. Observe the consistency and fineness of the coffee grounds to determine if the issue has been resolved.

If the troubleshooting steps mentioned above do not fix the problem, there may be other possible causes for the Delonghi Magnifica not grinding properly. It is important to check for any loose or damaged parts, such as the grinder motor or wiring. If necessary, consult the user manual or contact the manufacturer for further assistance and professional repair services.

Cleaning the Pre-Ground Coffee Bypass Chute

The bypass chute is where you add your pre-ground coffee to brew without using the grinder. This part of the coffee machine also gets clogged easily if not cleaned thoroughly.

To clean the bypass chute, you will need a cleaning brush or a small tool that can reach into the chute. Gently insert the brush or tool into the opening and carefully scrape away any trapped coffee particles. Be thorough in your cleaning to ensure all blockages are removed.

Avoid using water to clean this component or any other internal part of the machine. When using a damp cloth, ensure that there’s no water dripping from it. Same for the brush, make sure that it is completely dry before inserting it into the chute.

Reassembling the Grinder Components

If you have followed the troubleshooting steps mentioned earlier and cleaned the grinder components, it is now time to reassemble them. Proper reassembly is crucial to ensure the grinder functions optimally. Here are the steps to reassemble the grinder components:

Step 1: Align the Burrs

Start by aligning the burrs properly. Place the upper burr on top of the lower burr, ensuring that the alignment tabs are aligned correctly. Rotate the upper burr gently until it fits snugly into place and the alignment tabs lock in position.

Step 2: Secure the Bean Hopper

Next, secure the bean hopper onto the grinder. Ensure that the hopper is placed correctly and aligns with the grinder. Twist it clockwise until it locks into place. This will ensure that the beans are properly fed into the grinder for optimal grinding.

Step 3: Test the Grinder

Once all the components are reassembled, it is important to test the grinder to ensure it is working properly.

Fill the bean hopper with coffee beans, select your desired grind setting, and brew a shot of espresso. Observe the grinding process and listen for any unusual noises.

If the grinder is functioning smoothly and producing consistent coffee grounds, then you have successfully reassembled it.

By following these troubleshooting steps and reassembling the grinder components correctly, you should be able to fix common issues with the DeLonghi Magnifica grinder. Remember to perform regular maintenance on your coffee machine and follow the manufacturer’s recommendations to ensure optimal performance and a great cup of coffee every time.
