So I noticed my Maytag dishwasher, about 8yo, was leaking from below. I took off the kick plate and saw the drip, but also some wispy smoke-like vapors. It looks like dry ice or it is leaking some type of cold gas. It doesn't smell and it is not a fire smoke. I turned off the water and the power to it, but still leaking and still smoking. Any thoughts on what this is?
