Using this Bosch dishwasher lower basket wheel is a breeze. First, make sure your dishwasher is turned off and unplugged for safety. Remove the lower basket from the dishwasher. Locate the old wheel on the basket and gently remove it. Then, take the new wheel and clip it onto the exact spot where the old one was. Put the lower basket back into the dishwasher. When it comes to maintenance, every few months, you can clean the wheel with a mild dish soap and warm water to keep it running smoothly. As for the note, always double - check the model number of your dishwasher before installation to ensure a proper fit. If you have any doubts, don't hesitate to contact us.
