What's the oven doing with the water?
As long as the electricity doesn't work! Use the hair dryer to blow with the cold wind, every few days with nothing
It doesn't make any difference. Wipe it off and you'll soon be able to use it.The oven bottom plate is made of one body without any gap.
Don't be energized by a high wattage (above 200W) light bulb in the oven, bake it lit a few hours. The hair dryer is OK, but it needs someone to hold it.
