You should clean your Hamilton Beach Flexbrew Coffee Maker at least once a month. This will help ensure that the machine remains in top working order and continues brewing great-tasting coffee. You can also use this as an opportunity to descale the machine, which will help reduce mineral buildup inside the machine over time.

If you use filtered coffee or have been using a coffee maker for some time without cleaning it, you should also give the Hamilton Beach Flexbrew Coffee Maker an extra deep clean. This will help ensure that all machine parts are thoroughly cleaned and free of oils, residues, or any other buildup.

What Type of Cleaning Supplies Do You Need to Clean Your Coffee Maker? 

When cleaning your Hamilton Beach Flexbrew coffee maker, you will need a few supplies to get the job done. You’ll need some dish soap, a scrub brush or sponge, white vinegar, and paper towels. To start with, unplug the brewer from the outlet. Then empty any water remaining in the reservoir tank by pouring it into the sink.

Use a Scrub Brush

Next, use a scrub brush, sponge, and dish soap to clean the coffee maker’s exterior. Make sure you’re careful around electrical components and don’t get any water inside them. Wipe down the exterior with paper towels when you are finished. Now it’s time to descale your machine. To do this, you’ll need to fill the reservoir tank with a 50/50 mixture of water and white vinegar. Make sure that the tank is at least half full for the descaling process.

Step-by-step Instructions for How to Clean Hamilton Beach Flexbrew Coffee Maker

Step 1: Inspect the Exterior

Before you begin cleaning your Flexbrew, check the exterior for any dirt or particles. Wipe down the body with a damp cloth to remove any debris. Discard all coffee grounds and beans from the brew basket and empty out any leftover coffee in the carafe.

Step 2: Remove the Brew Basket and Carafe

Detach the brew basket and carafe from their respective positions on your Flexbrew. Empty all coffee grounds or beans, then wash both containers with warm water and dish soap. Rinse well after cleaning and thoroughly dry each component before reassembling them together.

Step 3: Clean the Hot Plate

At regular intervals, you should also clean the hot plate of your Flexbrew. To do this, pour a few drops of warm vinegar or lemon juice onto a cloth and use it to wipe down the hot plate. Make sure to remove any residue from all sides and corners. Once finished, rinse the hot plate with cold water and dry it off with a clean cloth.

Pour a Few Drops of Warm Vinegar

Step 4: Clean the Coffee Maker’s Interior

To sanitize the interior of your Flexbrew, fill the carafe with 8-10 cups of water mixed with 2 tablespoons of white vinegar. Place back into position and turn on the coffee maker to run the cleaning solution through. Once finished, discard the solution and run two more cycles of plain water to completely remove the vinegar from your brewer.

Finally, ensure all the components are completely dry before reassembling your Flexbrew coffee maker. Cleaning your coffee maker regularly will ensure you keep it in good working order for many years to come.

How Can You Prevent Future Build-Up in Your Coffee Maker? 

  • Use fresh, cold tap water to brew your coffee every day. This will help prevent mineral deposits from forming in the brewer over time.
  • Only use coffee grounds specifically for your FlexBrew Coffee Maker model (not all models can use the same type of coffee grind).
  • Descale your coffee maker regularly every 60-90 days, depending on the mineral content of your tap water.
  • Ensure that you have a secure lid for your carafe so that no grounds are spilled into the brewer and cause a build up of residue over time.
  • Rinse out any grounds or liquid from the carafe before brewing a new batch of coffee.
  • Clean the carafe and other removable parts regularly with warm, soapy water and rinse them thoroughly.
  • Make sure that all components of your FlexBrew Coffee Maker are completely dry before storing them or reassembling them for another brew session.

By following these steps, you can keep your Hamilton Beach FlexBrew Coffee Maker in optimal condition and prevent future mineral deposits or residue build-up.

How Often Should You Replace the Water Filters in Your Hamilton Beach Flexbrew Coffee Maker?

Regularly replacing the water filters in your Hamilton Beach Flexbrew Coffee Maker is important. How often you should replace the filters depends on how frequently you use the machine. If you use your coffee maker every day, it’s best to replace the filter at least once a month. However, if you only use it occasionally, then replacing the filter every three months should be sufficient.

To check the condition of the filter, remove it from the machine and inspect it for any discoloration or build-up. If you notice that the filter is clogged with debris, it’s time to replace it with a new one. Additionally, you may want to consider switching to a water filter specifically designed for coffee machines. This can help reduce the amount of buildup and ensure your coffee tastes fresh.

Check the Condition of the Filter

To replace the Hamilton Beach Flexbrew Coffee Maker filter, start by turning off the machine and unplugging it from the wall. Remove the old water filter, then insert a new one. Make sure that you have securely inserted the filter into its designated slot before plugging the machine back in. Once the filter is in place, you can turn on the coffee maker and start brewing your favorite cup of joe.


The biggest disadvantage of using this coffee maker is that it requires more time and effort to clean. This type of coffee maker has multiple parts that need to be removed and cleaned separately, which can be a hassle for some people. Additionally, the FlexBrew often creates a lot of debris, especially when grinding beans in the integrated grinder.

In conclusion,  the Hamilton Beach Flexbrew Coffee Maker is a great way to make delicious coffee at home. It can be cleaned easily and efficiently with little effort. With a few simple steps, you can keep your coffee maker running well for years to come.

When cleaning the machine, remember to use only mild soap and warm water, never harsh chemicals or scouring pads on any of the parts.
