Is it safe to have a dishwasher next to an oven?

Hi there, this should be no problem at all. Are you worried about fire safety or something else? If you worry about fire safety, you should not. The dishwasher is as safe (if not safer) as the electric oven. If you worry about water leaks, a water leak is bad by itself, but in this case it would not be worse, because of the oven or gas hob. I hope I was helpful. Have great holidays!
