Common Issues with the Keurig K-Suite Coffee Maker & Their Solutions (Step-by-Step Troubleshooting Guide)
Before diving into solutions, let’s first examine the most frequent issues users face with the Keurig K-Suite:
- No Power or Brewer Won’t Turn On
- Brewer Not Brewing or Brewing Partial Cups
- Brewer Leaking Water
- Brew Cycle Stops Midway
- Brewed Coffee Tastes Off
Each of these problems is solvable with a little maintenance and troubleshooting. Let’s walk through the solutions for each.
1. Keurig K-Suite Not Turning On – Power Issues
Symptoms:
- Power button doesn’t illuminate when pressed.
- The machine is unresponsive to button presses.
Solutions:
1.1 Check Power Connection
- Ensure the power cord is securely plugged into a grounded electrical outlet.
- Confirm the outlet is functional. You can test it by plugging in another device, such as a phone charger, to ensure it works.
1.2 Overloaded Circuit
- If multiple devices are plugged into the same circuit, your brewer may not get the necessary power. Unplug some devices and try again, making sure the brewer is on its own circuit.
1.3 Power Button Reset
- Hold the power button for 10 seconds. Release it and try turning the coffee maker on again.
1.4 Energy Saving Mode
- The Keurig K-Suite turns off automatically 90 seconds after the last brew to save energy. Press the power button to restart the brewer.
2. Brewer Not Brewing or Brewing Partial Cups
Symptoms:
- The machine does not brew any coffee.
- Only a small amount of coffee is dispensed.
Solutions:
2.1 Check Water Reservoir
- Ensure there is enough water in the water reservoir. The machine requires a minimum of 6oz of water to brew. If it’s too low, add more water and try again.
2.2 Clean the Exit Needle
- Grounds in the exit needle can clog the brewing process. Use a straightened paper clip to clean out the exit needle. Follow the cleaning instructions provided in the user manual.
2.3 Descale the Brewer
- If you haven’t descaled your machine in the last 3-6 months, mineral buildup may be blocking the water flow. Follow the descaling procedure in the manual to clear any scale deposits inside the machine.
3. Brewer Leaking Water – Water Leakage Issues
Symptoms:
- Water appears around the coffee maker’s base or on the countertop.
Solutions:
3.1 Check Water Reservoir Lid
- Make sure the water reservoir lid is properly closed. If the lid isn’t sealed tightly, it can cause water to leak during the brewing cycle.
3.2 Inspect for Cracks or Damage
- Check for any cracks or damage in the water reservoir or drip tray. If there are any cracks, the part may need to be replaced. Contact Keurig customer support for assistance.
3.3 Examine the K-Cup Holder
- A misaligned or clogged K-Cup holder can also cause water leakage. Ensure the K-Cup pod holder is properly seated in place.

4. Brewing Stops Mid-Cycle
Symptoms:
- The brewing process stops unexpectedly, before the cup is full.
Solutions:
4.1 Reset the Machine
- Sometimes, a system reset is required. Turn the machine off, unplug it for 5 minutes, then plug it back in and turn it on again.
4.2 Clean the Exit Needle
- If the exit needle is clogged, the brewer may stop mid-cycle. Clean the needle by following the exit needle cleaning instructions provided in the manual.

4.3 Check for Descaling Needs
- If the brewer is slowing down, this could be a sign of mineral buildup inside the machine. Follow the descaling procedure outlined in the manual.
5. Brewed Coffee Tastes Off – Unpleasant Coffee Flavor
Symptoms:
- The coffee tastes bitter, watery, or even has a plastic-like taste.
Solutions:
5.1 Use Fresh, Clean Water
- Ensure you’re using filtered or bottled water. Tap water, particularly hard water, can alter the taste of your coffee. Avoid using distilled water as it can cause brewing issues.
5.2 Clean the Brewer Regularly
- Regular cleaning is crucial for maintaining the fresh taste of your coffee. Clean the K-Cup holder, funnel, and water reservoir to avoid any build-up of old coffee grounds that might affect the flavor.

5.3 Use Keurig® K-Cup® Pods
- Ensure that you are using authentic Keurig® K-Cup® pods. Non-Keurig pods may cause malfunctioning and produce poor-tasting coffee.
General Maintenance and Cleaning Tips
Importance of Regular Cleaning
Regular cleaning prevents clogs and buildup that can hinder the performance of your Keurig K-Suite Coffee Maker. Follow these tips to keep your machine in top condition:
Cleaning the Water Reservoir
- Wipe the inside of the water reservoir regularly with a damp, non-abrasive cloth. After cleaning, leave it open to dry completely before refilling.
Cleaning the K-Cup Pod Holder
- Remove the K-Cup pod holder and clean the funnel and exit needle with a straightened paper clip.
Descaling Your Brewer
- Descale your brewer every 3-6 months using the Keurig® descaling solution. This helps remove mineral buildup that can affect the performance and longevity of the brewer.
Troubleshooting FAQ
What should I do if my Keurig K-Suite is not turning on?
Ensure the power cord is plugged in correctly and the machine is connected to a functional outlet. If it’s in energy-saving mode, press the power button to restart.

Why is my Keurig brewing only a partial cup of coffee?
This issue may arise if there isn’t enough water in the reservoir or if the needles are clogged. Clean the needles and ensure there is sufficient water before brewing.
How often should I clean my Keurig K-Suite?
To maintain optimal performance, clean the water reservoir, K-Cup holder, and exit/entrance needles at least once a month. Descale your brewer every 3-6 months.
My coffee tastes bitter. What could be causing it?
Bitterness can be caused by stale coffee grounds, unclean parts of the brewer, or poor-quality water. Ensure the brewer is clean and use fresh, filtered water. Only use Keurig® K-Cup® pods for the best coffee flavor.
Additional Troubleshooting Tips
Sometimes, issues may seem more complicated than they appear. Here are additional troubleshooting suggestions to keep your Keurig K-Suite brewing perfectly:

Overfilling the reservoir can lead to brewing issues. Ensure that you don’t exceed the MAX fill line and always maintain the water level between the MIN and MAX lines.
