Why is my coffee maker so slow?” You might be asking this same question when your coffee maker takes longer than usual to finish brewing. There can be a lot of reasons as to why this is happening, and it is always best to understand the causes so that you would know how to deal with it.

Why Is My Coffee Maker So Slow?

If the coffee or water does not seem to be flowing properly into the pot, then there might be a problem with the coffee maker itself. Although most of these problems can be easily fixed, you should still be aware of the things that you need to look for.

  • Mineral Build-up

Coffee granules have oil content which is extracted when the water gets through them. Water, on the other hand, has contents such as calcium and lime, which are substances that form deposits and accumulate, which will then make it harder for the coffee maker to heat your water while brewing. The mineral build-up, if not addressed, can cause damage to your machine, or can alter the smell and taste of your coffee.

  • Water Clog

When the water does not flow in your coffee maker properly, it can be an indication that your coffee pot tube is clogged which then prevents any liquid from flowing through easily.

What to Do with Slow Coffee Makers?

If your coffee maker is still functional and is not a total mess yet, then you should, of course, clean it first instead of getting a new one. The maintenance and cleaning of your machine should never be overlooked, even if you are only preparing for your daily coffee using a simple drip machine. Regular care and maintenance should start after each use and can be done by wiping off or cleaning the heating plate of spilled or dripped liquid.

If there is too much dirt accumulation or too many coffee drippings, then the warmer plate may not be able to reach the optimal temperature designated for it.

How to Clean Your Coffee Maker?

Cleaning the coffee maker will allow the water or any fluid to flow faster because the clogs and scales will be removed. Regular care and maintenance are among the easiest ways to keep your machine working properly and prevent issues with how it functions.

Due to the high moisture levels, coffee makers can easily harbor bacteria and molds. You can follow these tips and steps in cleaning your coffee maker.

  • Regular Cleaning After Each Use

To prevent the build-up of residues, you can quickly clean your coffee maker after each use. Disassemble the machine parts. You can start by removing all parts that come off such as the brew basket, the pot, and other components that are removable. Make sure to clean these separately from the rest of what’s left with the coffee maker.

Step 1: Wash all the removable parts. You can prepare a basin with warm soapy water where you can submerge all of the removable parts and then use a dish rag to wipe off any leftover coffee. Make sure to handle the glass parts with extra care.

Step 2: Wipe the outside part of the machine. You can use a soft cloth with soap and water to clean the outside part of the machine. Make sure to clean the warming plate of coffee grinds as well, and then wipe off the soap suds with a damp cloth.

Step 3: Reassemble your coffee maker. Put the parts back together once they are all dry and you are set to use it again!

  • Deep Cleaning 

There are instances when you really are in a hurry that you cannot afford to clean the machine anymore after using it. When your coffee maker is already functioning too slow because of clogged parts, then you have to do a deep cleaning method.

Step 1: Prepare a water and vinegar solution. You can mix water and vinegar, with amounts that will vary on your machine size. Pour the solution into the machine reservoir and let it sit for a few minutes.

Step 2: Turn on the machine and let it run half of a brew cycle. Allow the solution to drip down the pot, and once it is half full, then you can turn it off.

Step 3: Allow the solution to sit inside the pot and the reservoir for an hour. This will help the solution clean out residues or molds.

Step 4: Turn on the machine and continue the brew cycle. Make sure to complete the cycle which will filter the remaining solution. Once done, you can pour the mixture into the sink.

Step 5: Rinse with plain water. Make sure to run two brew cycles with only plain water to clean out any vinegar out of the machine.

Step 6: Wipe the parts with a clean cloth. Make sure to use a clean damp cloth to wipe the exterior part of the coffee maker to remove any debris, residues, dirt, and coffee grinds.


So, after a detailed discussion above, you may still be asking the same question you had earlier: Why is my coffee maker so slow?”

More often than not, the slow coffee maker issue is fixed after cleaning the device because, like any other equipment, coffee makers can get so used up and may not function at its best due to clogs. Now, if the steps we outlined above did not make any progress in the coffee making process, then perhaps you should consider having it checked by a professional as there can be other factors that may cause your machine to function at a slower rate.

For one, it can also mean that the thermostat, the pump valve, the heater, the timer or any other parts of the machine is of low-quality, stuck, or even broken. The professional might then suggest that you change or even upgrade such item.

Nevertheless, it pays to not give up on your tools yet at the first sign of complications. Most importantly, it is best to clean and maintain your equipment religiously to prevent other issues.
