The Xiaomi Multifunctional Rice Cooker 4L uses a traditional hot plate for heating. During the cooking process, the rice cooker controls the heating element's on-off state through the relay, thereby adjusting the cooking temperature and time. Hence, there will be a slight sound during the operation of the relay, which is normal and indicate the proper functioning of the device. Please feel free to use it.
Note:
1. Before cooking, please wipe off any residual water from the bottom of the inner pot to reduce popping sounds caused by the evaporation of water during heating;
2. If there are any other unusual noises from the rice cooker, please apply for after-sales services.
