If your Roper dishwasher is not dispensing soap, or the dishwasher soap dispenser is not opening during the cycle, the problem is usually a failed dispenser lever first, followed by a damaged detergent dispenser cover, a cracked detergent container, or a broken dispenser lid. In some cases, replacing the entire detergent dispenser is the simplest fix if multiple dispenser parts are worn or damaged. A bad control board can also keep the dishwasher detergent dispenser not working, but that is much less common and should be checked only after the dispenser parts themselves. Start by inspecting the dispenser lever, dispenser cover, detergent container, and dispenser lid for cracks, binding, or obvious breakage that could keep the detergent door from opening. If your dishwasher is not dispensing soap and dishes are still dirty after the cycle, this is a good place to start. RepairClinic.com makes it easier to match the right Roper part to your machine.

If there is a problem with the control board, it might not send voltage to the detergent dispenser, preventing the dispenser from opening. However, this is not likely the case. Control boards are often misdiagnosed—make sure you check more commonly defective parts before replacing the control board
