Regular cleaning and maintenance will ensure the longevity and optimal performance of your coffee maker.

Troubleshooting
If you encounter any issues with your REVOTRA Single Serve Coffee Maker, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Coffee not brewing / No water dispensing | Water reservoir empty or not properly seated. Red silicone plug not removed. Clogged needle. | Ensure reservoir is filled and correctly placed. Verify red silicone plug is removed. Clean the needle with a paperclip. |
| Weak coffee | Insufficient coffee grounds/pod strength. Incorrect brew size selected. | Use more coffee grounds or a stronger pod. Select a smaller cup size or the 'Strong' brew option. |
| Slow brewing | Mineral buildup (needs descaling). 'Strong' brew option selected. | Perform a descaling cycle. Note that 'Strong' brew intentionally slows the process for richer extraction. |
| Coffee grounds in cup | Reusable filter overfilled or not properly closed. | Do not overfill the reusable filter. Ensure the lid is securely closed. |
| Machine not turning on | Not plugged in. Power outlet issue. | Check if the power cord is securely plugged into a working outlet. |
