If your Amana dishwasher soap dispenser is not opening, the most likely problem is a broken dispenser lever, which can keep the detergent door from opening or closing the way it should. Next, check the detergent dispenser cover for cracks or damage, then inspect the detergent container and dispenser lid, since any of these damaged parts can stop the dishwasher detergent dispenser from working properly. If you do not want to take the dispenser apart piece by piece, replacing the complete detergent dispenser is often the simplest fix. A failed control board can also keep the dishwasher from dispensing soap by not sending voltage to the dispenser, but that is much less common and should be checked only after the dispenser components have been ruled out. When an Amana dishwasher is not dispensing soap, a close visual inspection of the dispenser lever, dispenser lid, detergent dispenser cover, and detergent container will usually point you in the right direction.

Control boards are often misdiagnosed—make sure you check more commonly defective parts before replacing the control board
