How to Fix a Clogged Coffee Maker? Easy Methods

The best way to fix a clogged coffee maker is to use a mixture of vinegar and water to descale the machine and remove any mineral deposits that may be blocking the water flow. This is a simple and effective method that can restore your coffee maker to its optimal performance and prevent future clogs. In this article, we will explain how to do this step by step, as well as provide some tips and tricks to keep your coffee maker clean and functioning well.

Why Does a Coffee Maker Get Clogged?

A coffee maker can get clogged for various reasons, but the most common one is the buildup of mineral deposits, also known as scale, inside the machine. Scale is formed when hard water, which contains high levels of calcium and magnesium, evaporates and leaves behind a crusty residue. This residue can accumulate in the water reservoir, the heating element, the tubes, the filter basket, and the spray head of the coffee maker, reducing the water flow and affecting the taste and quality of the coffee.

Other factors that can cause a coffee maker to get clogged are coffee grounds, oil, and dirt. Coffee grounds can get stuck in the filter basket or the spray head, creating a blockage that prevents the water from reaching the coffee. Oil and dirt can also accumulate in the machine over time, especially if it is not cleaned regularly. These substances can create a film that coats the internal parts of the coffee maker, making it harder for the water to pass through and impairing the flavor of the coffee.

How to Fix a Clogged Coffee Maker with Vinegar and Water

Follow these steps to descale your coffee maker and remove any clogs:

  1. Unplug the coffee maker and empty the water reservoir. Make sure the coffee maker is turned off and unplugged before you start cleaning it. Also, remove any leftover water from the reservoir and discard any used coffee grounds or filters.
  2. Fill the water reservoir with a 50/50 mixture of vinegar and water. Vinegar is a natural and safe acid that can dissolve the mineral deposits and other impurities in the coffee maker. You can use any type of white vinegar, but avoid using flavored or colored vinegar, as they may leave a residue or a smell in the machine. The amount of vinegar and water you need will depend on the size of your coffee maker, but a general rule of thumb is to use one cup of vinegar for every four cups of water.
  3. Run a brew cycle with the vinegar and water mixture. Place a large pitcher or bowl under the coffee maker to catch the liquid. Turn on the coffee maker and let it run a full brew cycle with the vinegar and water mixture. This will allow the vinegar to circulate through the machine and dissolve any clogs or scale. Do not use a paper filter for this step, as it may absorb some of the vinegar and reduce its effectiveness.
  4. Let the coffee maker sit for 15 to 20 minutes. After the brew cycle is complete, turn off the coffee maker and let it sit for 15 to 20 minutes. This will give the vinegar more time to work on the stubborn clogs or scale. Do not leave the vinegar in the machine for longer than 20 minutes, as it may damage the plastic or rubber parts of the coffee maker.
  5. Run two or three more brew cycles with plain water. After the waiting period, empty the pitcher or bowl and refill the water reservoir with plain water. Run two or three more brew cycles with plain water to rinse out the vinegar and any remaining impurities from the machine. Make sure the water runs clear and does not have any vinegar smell or taste.
  6. Wipe down the exterior and the filter basket of the coffee maker. Use a clean cloth or sponge to wipe down the outside of the coffee maker and the filter basket. This will remove any dust, dirt, or oil that may have accumulated on the surface. You can also use a paper filter to clean the spray head, by placing it in the filter basket and running a brew cycle with plain water. This will help remove any coffee grounds or scale that may be stuck in the spray head.

How to Prevent Your Coffee Maker from Getting Clogged

To prevent your coffee maker from getting clogged in the future, you should follow these tips and tricks:

  • Clean your coffee maker regularly. Depending on how often you use your coffee maker and the quality of your water, you should descale your coffee maker with vinegar and water at least once every three to six months. This will keep your coffee maker in good condition and ensure that your coffee tastes great. You should also wipe down the exterior and the filter basket of the coffee maker after each use, and wash the carafe and the lid with warm soapy water once a week.
  • Use filtered or distilled water. One of the main causes of clogs and scale in coffee makers is hard water, which contains high levels of minerals that can leave a residue in the machine. To avoid this, you should use filtered or distilled water to brew your coffee, as they have lower mineral content and are less likely to cause buildup. You can also install a water filter on your faucet or use a water pitcher with a filter to reduce the hardness of your water.
  • Use the right amount and grind of coffee. Another factor that can cause clogs in coffee makers is using too much or too fine of coffee grounds. This can result in the coffee grounds overflowing the filter basket or getting into the spray head, creating a blockage that prevents the water from reaching the coffee. To avoid this, you should use the right amount and grind of coffee for your coffee maker, following the manufacturer’s instructions or the guidelines on the coffee package. Generally, you should use one to two tablespoons of coffee per six ounces of water, and a medium-fine grind for drip coffee makers.
