I followed the instructions  given on the manual, step by step. First, I put on empty to check if there's any issues. I could feel a strange smell but was specified on the manual about it, and it was something normal for the first try. After this test, I use bread. Has 6 levels, and you can select depending on how you like the bread. There are many ways to set depending on your preferences. Very easy to set up and use. On the left side has a tray that's come off and can be cleaned properly. Works perfectly,  no issue
