Using this ASKO lower basket wheel is easy. First, make sure your dishwasher is turned off and unplugged for safety. Remove the bottom basket from your dishwasher. Then, replace the old wheel with this new one. Make sure it fits snugly. When you're done, put the basket back in the dishwasher. As for maintenance, keep the wheel clean. You can wipe it down with a damp cloth from time to time. If you notice any signs of wear or damage, check with us.
