If there is smoke and a burnt smell produced by the Xiaomi Toaster, please refer to the following steps to troubleshoot:
Please clean the crumb tray and maintain the toaster regularly to ensure there is no too many crumbs;
Using a high toast level for thin or sweet bread will cause excessive browning or burning. Lower the setting if needed;
Bread with coatings like butter, cheese, or sugar can melt, drip, and burn inside the toaster, causing smoke and odor;
If the toaster has just completed a cycle, cool down it before starting a new one.
If the problem is still not solved, please contact the local official after-sales service center for further assistance.
