Many coffee enthusiasts across the United States have faced similar issues.

Common Issues and How to Fix Them
Keurig Won’t Turn On
If your Keurig K-Express isn’t powering up, consider the following steps:
- Check the Power Source: Ensure the power cord is securely plugged into a working outlet.
- Unplug and Reset: Unplug the machine, wait for 5 minutes, then plug it back in. This can reset the internal components.
- Inspect the Power Button: Press the power button firmly. If it feels loose or unresponsive, there might be an internal issue.
- Thermal Reset: Some users have reported that the thermal fuse can trip, especially after descaling. To reset, unplug the machine, remove the water reservoir, and let it sit for 10 minutes before plugging it back in.

Keurig Not Brewing
If your Keurig powers on but doesn’t brew coffee, try these steps:
- Run a Water-Only Cycle: Place a mug on the drip tray, lift and close the handle without inserting a K-Cup, and press the brew button. This can clear any blockages.
- Clean the Needles: Use a paperclip to gently clean the entrance and exit needles, which can become clogged with coffee grounds.
- Check the Water Reservoir: Ensure it’s filled above the minimum line and properly seated.
- Prime the Pump: If the machine has air bubbles, gently shake it upside down over the sink to dislodge them.

Keurig Brewing Weak or Cold Coffee
If your coffee is weaker or cooler than usual:
- Descale the Machine: Mineral buildup can affect performance. Use a descaling solution or a mixture of equal parts white vinegar and water. Run the solution through the machine, then rinse with clean water.
- Check the Heating Element: If the coffee is cold, the heating element might be malfunctioning. This may require professional repair.
- Use Fresh Water: Old or stagnant water can affect taste and temperature.

Keurig Leaking Water
Leaks can occur from the bottom or during brewing:
- Inspect the Water Reservoir: Check for cracks or misalignment.
- Examine the O-Ring: A damaged O-ring can cause leaks. Replace it if necessary.
- Check the Drip Tray: Ensure it’s properly seated and not overfilled.
- Clean the Needles: Clogged needles can cause water to leak.

Keurig Showing “Add Water” Even When Full
This issue can be caused by:
- Dirty Water Reservoir: Clean it with warm, soapy water.
- Clogged Water Filter: Replace the filter if it’s old or clogged.
- Misaligned Reservoir: Ensure it’s properly seated.
- Clean the Valve: Use a damp cloth to clean the area where the reservoir connects to the machine.

Keurig Lights Flashing or Blinking
Flashing lights can indicate various issues:
- Descale the Machine: A flashing descale light often means mineral buildup.
- Reset the Machine: Unplug the machine, wait for 5 minutes, then plug it back in.
- Check for Blockages: Ensure there are no obstructions in the needles or water lines.
