Why does my coffee grinder keep jamming?

A coffee grinder is essential for making a great cup of coffee, but when it suddenly jams, it can ruin your coffee experience. If you find your coffee grinder isn't working properly, don't panic.

Understanding Why a Coffee Grinder Is Jamming

A coffee grinder that's jammed isn't usually due to a problem with the machine itself, but rather improper use or maintenance. Here are some of the most common reasons:

• Grind setting too fine: This is the most common cause. When the grind setting is too fine (especially for espresso), tiny coffee particles can pack tightly between the grinding wheels, causing the grinder to jam.
  
  
• Excessive oils in the coffee beans: Dark roasted coffee beans are often high in oils. During the grinding process, these oils gradually adhere to the grinding wheels and channels of the coffee grinder, forming a sticky residue that can block the grinder's operation.
  
  
• Coffee residue buildup inside the grinder: Whether you use a blade or burr grinder, neglecting to clean it over time can lead to a buildup of coffee grounds and oils. This buildup can harden, like cement, and eventually cause the grinder to jam.
  

Solution: How to Fix Your Coffee Grinder

If your coffee grinder is stuck, try the following:

Adjusting the Grind Size

First, turn the grinder back on to its coarsest grind size and restart it. This will help loosen any clogged coffee grounds.

Clean the Grinder Thoroughly

• Disassembly: Carefully remove the grinding wheel according to your grinder's instructions.
• Cleaning: Use a small brush, toothbrush, or vacuum cleaner to remove all coffee grounds and oily residue. You can also use a coffee grinder made with clean beans (a special grain) to absorb oil and remove any residue.
• Reassembly: Ensure all parts are completely dry before reassembling.
  
  

Changing Coffee Beans

If your coffee beans are very oily, try switching to a medium or light roast. This will not only reduce the risk of the grinder jamming, but also improve the coffee's flavor.

A coffee grinder that is regularly cleaned and used properly can provide years of enjoyment. By understanding why your coffee grinder gets stuck and mastering the proper maintenance methods, you’ll be able to easily resolve the issue and ensure every cup of coffee is of the best quality.
