Now, with the development of science and technology, microwave ovens have more and more functions. In the past, microwave ovens were cleaned manually, but now microwave ovens have steam function, which is actually self-cleaning by machines. The specific operation steps are as follows.

First add water to the water tank, hang it on the machine, and close the microwave oven door.

Second, press the steam cleaning button when the clock is displayed.

Third, press the start button again, and the microwave oven will enter the steam cleaning program.

Fourth, after the process is over, after the gas inside is cooled, dry the excess water with a rag.
