Torx screws are commonly found on appliances and electronic equipment put together by machines. These screws are made for a specified amount of torque to be applied when they tighten. They're much better at holding materials together than flat head or Phillips screws. On a dishwasher, Torx screws are mostly found on the inside of the door and usually hold the door panel in place. Removing Torx screws from a dishwasher requires a Torx screw set and socket screwdriver so the correct Torx screw can be applied.
Unplug the dishwasher or turn off the power to the circuit that controls the dishwasher. This will help prevent accidental shock.
Locate the correct Torx screw size that will fit your screw. You can do this by hand, by inserting different Torx sizes into the Torx screws on the dishwasher. Ensure that you get the correct size, as a Torx head that is too large or too small will damage the screw. You can also consult the service manual for your dishwasher that might contain information on the Torx screw size.
Insert the Torx screwdriver head into your screwdriver handle. Insert the screwdriver and Torx head into the screw to be removed and turn counterclockwise.
Spray penetrating lubricant on any stubborn or rusted out screws. Allow the lubricant to soak according to manufacturer's instructions. Remove the screws.
