How to Fix / Troubleshooting
Safety first: Turn off and unplug the brewer before any handling.
- Basic reset: Unplug the unit for at least 5 minutes. Remove the water reservoir and drip tray. Press and hold the power button (if present) for 10 seconds to discharge residual power, then reconnect everything and power on.
- Check reservoir and float: Ensure the reservoir is full and the float moves freely. Clean as needed.
- Remove K-Cup and accessories: Try powering up with no K-Cup, no filter, and only the reservoir installed to minimize variables.
- Firmware reset (model-specific): Some models allow a factory reset via a button combination (e.g., holding power and brew). Consult the manual and perform the reset.
- If NOT READY persists: The main control board or a critical sensor is likely faulty. Professional diagnosis and board replacement may be required.
