My machine was constantly generating LF errors, and would stop at the 24 min mark of the cycle, too. The filters were clean, so i suspected the solenoids went bad. The fix was quite simple and I replaced the inlet valve/solenoid assembly. There were few screws to remove, and the trickiest part was popping open the lid assembly to access the water outlets without damaging the paint. Took about 30 minutes and easy to do. The new assembly has just a few minor differences amd comes with all new wires.
