How to Fix F01 Error (Step-by-Step)

Turn off the water supply and unplug the dryer and confirm the error stays cleared during a full test cycle.
Access the rear of the dryer to locate the water inlet valve.
Place a towel beneath the hoses to catch any residual water and then disconnect them from the valve.
Remove the mounting screws that hold the inlet valve in place.
Carefully disconnect the electrical wires from the old valve and confirm the error stays cleared during a full test cycle.
Install the new inlet valve by securing it with the mounting screws and reconnecting the electrical wires.
Reattach the water hoses, turn the water supply on, and check for leaks before plugging the dryer back in.
Turn the appliance off, wait about 2 minutes, then turn it back on.
