"LF" is a "LONG FILL" error. This will occur if water fill time exceeds 10 minutes. I don't know why this would pop up at the end of a cycle. Normally this is associated with filling at the beginning of a cycle. There is also an "FL" error, which is an "OVERFILL" error. This is normally associated with a problem with either the control board or wiring harness. This normally occurs when there is an open circuit between pins 1 and 3 on P17 of the control board. That one is a little more involved and usually requires replacement of the control board, wiring harness, or both. If you, indeed, have an "LF" error I would check your water source coming in. Check your fill hoses for kinks or obstructions, first. Then, turn the water supply off and remove the hoses from the back of the machine. Place one end of each hose inside the wash tub and turn both water supply lines back on to make sure you have good water flow coming through the hoses. Replace the hoses if they show signs of bulging, cracks, leaking and/or restricted water flow. Turn water back off and check the fill valve inlet ports on the back of the washer for accumulations of sediments in the screens. It doesn't take much to restrict water flow. You can clean the screens with a cotton swab. If you check everything and still have problems with the error code popping up, I would replace the fill valve. It's an easier fix and less expensive than a control board. If you decide to replace the valve, it is located under the console on your washer, I believe. It's fairly simple with a couple of screws to remove on the console and a couple of connectors and hoses on the valve to remove. Make sure you unplug the machine and turn off the water supply before attempting. I hope you find this advice helpful. Let me know if this works for you.
