This morning the water accidentally got to the machine, that is, the handle above the water, the keys inside the accidentally a little into the water, and then I removed the handle to find the crevice

Just a small amount of splash on the water, generally speaking, it is all right, simply deal with it on the line, if you fall into the water on the trouble, in addition, your way of dealing with it is not desirable, electronic products are very taboo with a hair dryer, hair dryer are hot air, there will be damage to the machine, the correct way is to dry naturally.
