When the E3 error code appears on the screen of your Midea soymilk machine, it indicates that there may be a problem with the machine's sensor. The sensor is a key part of monitoring the temperature and pressure inside the machine, and if it fails, the machine will automatically stop operating to ensure user safety. In this case, the first step is to stop using it immediately and then seek professional help from Midea’s after-sales service center.

This error code may result from a damaged or short circuited sensor. For example, if the soymilk maker is accidentally splashed with water, the sensor may be damaged. It is wise to check for liquid intrusion before disposal. Once discovered, be sure to disconnect the power supply and ensure that the soymilk machine is completely dry before trying to restart it. If it occurs occasionally, restarting may be a temporary solution to the problem.

However, if the E3 error code is displayed frequently or is accompanied by other abnormal conditions, it is strongly recommended that you contact Midea after-sales service directly. They can provide professional diagnostic and repair services to ensure that your soy milk machine is functioning properly and avoid potential safety hazards. Never ignore these warning signs, timely maintenance and repairs are crucial.
