Clothes still dirty

My machine is approximately 4 years old. It's not cleaning the clothes I've washed the same load of laundry 6 times very small loads and they are still coming out dirty. I always use he detergent and I've tried 3 different types on the same load of laundry. A few times it would come out with barely any water half of the things are still dry. Is there anything that Maytag would do and how can I fix this
