Troubleshooting
If you encounter any issues with your Moosum Rice Cooker, please refer to the following common problems and solutions:
- Cooker does not turn on: Ensure the power cord is securely plugged into both the cooker and a working electrical outlet. Check your household circuit breaker.
- Rice is too dry/hard: You may need to add slightly more water for your specific rice type or preference. Ensure the lid is properly sealed during cooking.
- Rice is too wet/mushy: You may need to reduce the amount of water. Ensure the rice is rinsed properly before cooking.
- Rice sticks to the bottom: Ensure the inner pot is clean and dry before adding rice and water. Some rice types are more prone to sticking; a thin layer of cooking oil can sometimes help.
