Now it makes sense. My maybe 4 year old unit shut down this morning and the display read FLT. I looked for my manual almost sure the filter needed to be changed. Couldn't find it so I went on line. There i found the manual but didn't recognize half of the things in there. It said "flt" meant i had to clean the evap coil. Okay- never saw that before. So I cleaned it and reset the machine and its fine. But now I happened upon this. More research and I realized I was reading the manual for the new model. DOH. Guess I do need a filter after all.
