I caused my washer to leak over the weekend by not replacing the filter tight enough after removing it for cleaning. Lucky for me, I was home, noticed water building up in the washer pan, and was able to stop the leak and suck it up with a wet/dry vac. Unlucky for me, we still ended up with the pictured water damage in the kitchen ceiling below the washer.
I plan to pull out the washer and inspect the pan this weekend. I suspect is it cracked, or possibly -- since it was installed by the seller as one of the items required by our home inspector -- the drain may not actually be connected to anything?
But in the meantime, should I be worried about the resulting damage? It consists of the long stained line and the stained "splat", and several shorter stained lines outside the picture. I can't imagine that much water got in there, but I have no way to tell that without removing part of the ceiling. Should I be concerned about mold, or just apply a stain blocker, repaint and forget about it?
