Check the Water Level

Before starting any troubleshooting, it is essential to check the water level in the reservoir. If the water level is too low, refill it and test the machine again. This simple step can often resolve the problem.

Reset Your Cuisinart SS-15

If you made sure that the water tank is full the next thing you could try is resetting your Cuisinart SS-15. Here is how to do that:

  1. Detach the water reservoir from the coffee maker.
  2. Find the toggle switch on the right side of the unit.
  3. Flip the toggle switch on and off continuously for 60 seconds.
  4. Unplug the machine from the power outlet and leave it unplugged for at least 10 minutes.
  5. Place the water reservoir back onto the coffee maker.
  6. Plug the coffee maker back into the power outlet. The unit should now be reset.

Unclog And Clean The Needles

Both the upper and lower needles may become clogged over time, leading to flashing blue lights and water flow issues. The upper needle is located on the bottom of the lid, while the lower needle is near the base of the machine.

Use a paper clip or a small gauge copper wire to clean any clogs or debris from the needles. Gently insert the tool into the needle and remove any buildup.

After completing all the steps, test the machine to see if it is working properly. If the issue persists, consider contacting Cuisinart customer service for further assistance.

Descale Light Stays On

Another common problem is that the descaling light does not go out. This is usually because the proper descaling process was not followed. Here is how to descale your Cuisinart SS-15:

Fill the reservoir with a 50/50 mixture of white vinegar and water, and put a cup underneath the machine. Then press the 6oz and 8oz buttons simultaneously for 2 seconds, it should then dispense water, do this until the water tank is empty.

After descaling, brew 4-6 cups of plain water to flush out any remaining vinegar and ensure the unit is clean.

Descaling the machine can help remove any mineral buildup that may be affecting its performance. Here is a video explaining the descaling process:
