What does the F20 error code mean and how do I fix it?

The F20 error code indicates a water inlet problem — no water or insufficient water supply is reaching the washer. Press PAUSE/CANCEL twice to cancel the cycle and unplug the washer, then check that both hot and cold water faucets are fully turned on, that inlet hoses are not kinked or frozen, and that the screens at the inlet hose connections are not clogged. Plug the washer back in, re-select your cycle, and press START; if the problem remains, call for service. (Page 23)
