LF Error

"LF" is a Long Fill error. If the fill time exceeds roughly 10 minutes, the fill valves are shut down and the error code is generated. If the error does not clear, or keeps reoccurring, it is recommended that you doublecheck to make sure your water taps are on all the way and check the hoses for kinks or clogs. If everything checks okay, check the screens on the fill valve for sediment build up. You may need to replace the valve.

We had the sae problem
checked the hoses and nothing... finnaly my fiance swapped the hot with the cold and the cold with the hot and it works just fine... maybe other people are having this problem and try everything then get a new one... so i thought id just share my experience so you could try that before going to drastic measures!
