What is the best way to replace the seal on a Kenmore dishwasher?

To replace the seal on a Kenmore dishwasher, first, turn off the power and water supply. Remove the old seal by pulling it out of the channel. Clean the channel thoroughly. Insert the new seal into the channel, ensuring it is properly aligned and secure. Turn the power and water supply back on and test the dishwasher to ensure the seal is working correctly.
