If the Xiaomi Electric Pressure Cooker 4.8L leaks air when cooking, please refer to the following methods for troubleshooting:
1. Ensure that the silicone sealing ring inside the lid is not aged, deformed, or damaged. A compromised seal can lead to steam escaping;
2. Check if the inner pot and the main body of the pressure cooker are deformed. Any warping can prevent proper sealing, causing leaks;
3. Verify that the vent valve and float valve are correctly installed and not loose. Improper installation can result in steam leakage;
4. Make sure the lid is securely locked in place. If the lid is not properly closed, it can lead to excessive steam escaping;
5. If the above methods do not resolve the issue, please contact the local after-sales service for further assistance.
