If the toasted bread color by the Xiaomi Toaster is light, please refer to the following steps to troubleshoot:
Please increase the toast level if a low toast level is selected;
Make sure the toaster is properly plugged in and receiving full power. Low voltage can affect heating;
Different types of bread toast differently. Some bread brown slower. Adjust the level accordingly;
Clean out any crumbs in the toaster tray, as buildup can affect heating efficiency;
Run a short cycle without bread to ensure the heating elements are working well.
If the problem is still not solved, please contact the local official after-sales service center for further assistance.
