We just had our 3670RL serviced for a few issues, the main reason, the long cabinet that stands on the counter, and goes to the ceiling, came off. I noticed there were bubbles on the exterior, like when wallpaper isn't laying flat. I thought it was from aleak, and sure enough, they said there had been one, stemming from the gutters. They removed the gutter, and resealed. My question is, has anyone had the same type of bubbles, and what has happened later on, as far as worsening, etc?
