What does the error code F8E1 mean and how do I fix it?

F8E1 indicates a water supply error. Check that both hot and cold water faucets are turned on, both hoses are attached with water flowing to the inlet valve, there are no kinks in the inlet hoses, and the inlet valve screens on the washer are not clogged. Press POWER/CANCEL once to clear the code, then restart the cycle. (Page 17)
