Hamilton Beach Flexbrew K-Cup Not Brewing

When your FlexBrew doesn’t make coffee from a K-Cup, it’s usually because of any of the following reasons:

  • Clogged Needle

Over time, coffee grounds and mineral deposits can build up, and block the tiny needle that pierces the K-Cup. This blockage prevents water from flowing through the coffee grounds. This is why your coffee maker is not brewing!

  • Incorrect K-Cup Size

If the K-Cup size is too large or too small for the brew setting you selected, the coffee maker may not brew well.

  • Wrong  K-Cup Placement

If the K-Cup is not inserted properly in the holder, it won’t engage well with the coffee maker. 

  • Water Flow Problems

Issues with water flow such as blocked water lines, and wrong connection of the water reservoir can also lead to brewing problems.


  1. Unplug your coffee maker and carefully clean the needle that punctures the K-Cup with a paperclip.  Run a water-only cycle to flush out any remaining debris.
  2. Make sure you’re using the standard K-Cups recommended by the manufacturer. Check your user manual to know more.
  3. Check if the K-Cup is placed properly in the holder. Make the necessary adjustments.
  4. If you suspect a water flow issue, check the user manual for instructions on how to clean the water line or reservoir.

Hamilton Beach FlexBrew K-Cup Not Heating Water

 If your FlexBrew isn’t heating water, it could be because of these:

  • Faulty Heating Element

Over time, the heating element can wear out or become damaged. This prevents your brewer from heating water.

  • Power Supply Issues

Issues with your power supply such as a faulty outlet, tripped circuit breaker, or frays on your power cord can make your Flexbrew K-cup not to heat water.


  1. Check if the brewer is properly plugged in and the power outlet is working.
  2. Make sure the power cord is properly connected, and there’s no damage
  3. Test the heating element for continuity. Replace it if it’s faulty.

FlexBrew K-Cup Leaks Water

Water leaks can occur due to a few reasons. Water can escape from loose or damaged seals within the coffee maker. Cracks in the water reservoir or improper assembly of the parts of the coffee maker, like the drip tray, can also cause leaks.


  1. Inspect the seals of the brewer for damage. If you find any, replace them with compatible replacement parts.
  2. Examine the water reservoir and other components for visible cracks or holes. Replace damaged parts.
  3. Reassemble the coffee maker carefully. Make sure all components, especially the drip tray and water reservoir, are correctly aligned and placed properly.

Coffee Has Inconsistent Taste

When your coffee tastes inconsistent, it’s usually due to uneven water flow during brewing. This can happen if the internal components of your coffee maker aren’t clean, due to coffee residue or mineral deposits blocking the internal components. Incorrect brew settings, such as the coffee strength or brew size, can also cause variations in taste.


  1. Clean your coffee maker thoroughly. Also, clean the internal components like the coffee funnel and water channels, so water can flow freely.
  2. Check and adjust the brew settings to match your coffee taste preferences.  

Coffee Has Unusual Smells or Tastes

If your coffee has an unusual odor or taste, it could be due to mineral buildup inside the brewer or coffee residue that hasn’t been thoroughly cleaned. It could also be related to the type of water you’re using, especially if it has a strong flavor or odor.


  1. Clean the coffee maker thoroughly, don’t forget to also clean the water reservoir and brewing components. 
  2. Use filtered or distilled water if your tap water has an unusual taste or odor.
