I have a Maytag dishwasher model # MDBH949WW1. It will let me choose what cycle I wish to run, but it won't let the cycle start. For example... I can choose Normal Load with Heated Dry; both buttons light up, but when I press the start button, nothing happens. It also wont allow me to choose Rinse Only or Delay Start. I have replaced the door gasket thinking that may be causing it. I also removed the bottom pump cover and removed any debris that I found (toothpick, food particles, etc). It will run a diagnostic cycle in which I can tell it is filling with water and draining OK. Although, I do notice maybe a grinding noise or what could be debris that Ive missed being tossed around. Any help you can provide would be greatly appreciated! Thank you.
