GE Adora detergent dispenser problems

The detergent and rinse aid dispenser on my dishwasher are not working. The detergent dispenser door does not open and no rinse aid is expelled. I replaced the entire detergent dispenser and that did not fix it so then I replaced the dishwasher control board but unfortunately that did not fix it either. I’m all out of ideas for what may be causing this. I’m a novice at repairs like this so I’ve just been depending on the internet for trouble shooting ideas. Any help you guys could give me would be great!
