Turn off the water supply valve to the GE Profile dishwasher. Disconnect the screws holding the kick panel in position on the front of the dishwasher and lift off the front panel.
Locate the float assembly, a large white device on the lower right-hand side of the dishwasher. The switch is beneath the float assembly and is usually a black device with two wires connected to it.
Label the wires so you can replace them correctly when you're finished and then pull on the wire connectors with a pair of needle-nose pliers to remove them.
Remove the screws holding the float switch onto the assembly and disconnect the switch to remove the switch from the dishwasher.
