Using this AEG dishwasher lower basket wheel is easy. First, locate the old wheel on the lower basket of your dishwasher. Carefully remove the old wheel by detaching it from the basket. Then, take your new wheel and align it with the mounting point on the basket. Simply clip it on until it's securely in place. When it comes to maintenance, it's a good idea to check the wheel regularly for any signs of wear or debris. If you notice dirt or grime on the wheel, you can use a mild detergent and a soft cloth to clean it. Just make sure the dishwasher is unplugged before you start any cleaning or maintenance work. As for installation, if you're not sure, you can always refer to your dishwasher's user manual. And remember, this wheel is fully guaranteed, so if you have any issues, we're here to help.
