Cleaning the Brewer
Regular cleaning helps prevent clogs and flavor carry-over. Use a damp cloth to wipe the exterior and drip tray. Remove the drip tray and water reservoir for thorough cleaning.
Use a Keurig rinse pod or run plain water through the machine to clear residual coffee oils.
Descaling Your Keurig
- Empty the water reservoir and fill it with descaling solution or a mixture of equal parts water and white vinegar.
- Place a large mug on the drip tray.
- Run a brew cycle without a K-Cup until the reservoir is nearly empty.
- Repeat the process with clean water to rinse out any remaining descaling solution.
- Clean the needle using a paperclip or Keurig maintenance tool.
Addressing Common Issues
If your Keurig isn’t brewing or is brewing slowly, check for clogs or mineral buildup. Clean the needle and descale regularly. For persistent issues, reset the machine by unplugging for 30 seconds, then plugging back in.
If water leaks, inspect the water reservoir seal and ensure proper placement.
