Let’s walk through a few quick questions to help you troubleshoot. **Q: Did you accidentally tap the button a second time during the brew cycle?** **A:** Touching the button again while brewing will stop the cycle. If this happened, try the following: - Remove the carafe from the base for a moment, then place it back. - Press the button once to restart the brew. --- **Q: Was the “Ready” light flashing rapidly when the brew stopped?** **A:** A fast-blinking “Ready” light usually means your machine has entered [Cool-Down Mode](https://help.ratiocoffee.com/firmware-update-2024?hsLang=en): a built-in safety feature that activates if the system begins to overheat. **If your machine enters Cool-Down Mode:** - Remove the carafe from the base. - Wait 5–10 minutes before pressing the button or adding water. - Once the “Ready” light stops flashing, you’re safe to begin brewing again. Entering Cool-Down Mode is often a sign of internal limescale buildup. When mineral scale accumulates, it can restrict water flow and lead to overheating. To prevent this, we recommend descaling monthly. [Click here to view our current descaling instructions](https://help.ratiocoffee.com/how-to-clean-your-ratio?hsLang=en).  --- **Q: Has it been a while since your machine was last descaled?** **A:** If it’s been over a month, scale buildup could be the cause. Excess mineral buildup can: - Cause the water sensor to misread the water level (stopping the brew early). - Reduce heater performance, preventing efficient water heating. **To troubleshoot:** 1. Run **2–3 full descaling cycles** using our recommended [descaling instructions](https://help.ratiocoffee.com/how-to-clean-your-ratio?hsLang=en). 2. Let the machine **rest for 5 minutes** between each phase of the descaling cycle. 3. Between each full descaling cycle, allow the machine to **rest for 10 minutes** before starting the next. 4. After you've completed 2-3 descaling cycles, let your machine **rest for 10 minutes** before brewing a new batch of coffee. --- **Still having trouble?** If your machine continues to stop mid-brew after descaling, it may need professional service to remove stubborn buildup or address a sensor issue.
