After several uses, it is important to clean the dishwasher to prevent the buildup of residue, bad odors, and to maintain its effectiveness in washing. Here are some steps to clean a dishwasher after heavy use:

Empty the dishwasher of all dishes and utensils, and remove any food debris or debris that may be present at the bottom of the dishwasher.

Remove the washing arms of the dishwasher and clean them with mild soap and water. Make sure the holes in the washing arms are clean and unobstructed.

Clean the rubber seal that surrounds the dishwasher door with a damp cloth and mild soap to remove any dirt or residue buildup.

Place a bowl or cup on the top rack of the dishwasher and fill it with white vinegar. Run the dishwasher in a full cycle wash with hot water. The vinegar will help disinfect and remove any odors from the dishwasher.

If there are still stains or dirt buildup inside the dishwasher, use a special dishwasher cleaner. Follow the manufacturer's instructions and make sure the cleaner is safe to use in your specific dishwasher model.

Finally, run another cycle wash with hot water to rinse any vinegar or cleaner residue from the dishwasher.

By following these steps, you should be able to clean your dishwasher and keep it in good working condition. It is recommended to perform this deep cleaning at least once a month or whenever the dishwasher is perceived to not be cleaning properly.
