Hmm, and you know why I had no hot water?
Because someone who likes to get up there and who shall remain nameless (Nicki) dislodged this little tube.
Took the repairman, what, two seconds (if that) to "fix."
I saw the tube hanging down this morning and thought that wasn't right (lol), but I couldn't see where the end went and the schematics in the manual were not helpful to me.
At least I know how to "repair" it if the same thing happens again!
Crazy cat.

Have a great weekend!
Glad it was an easy fix!
Kim, we are so glad it wasn't something serious, and that you know what to look for if this happens again.
Have a wonderful, restful weekend!
