If your Haier dishwasher is not dispensing soap, start with the dispenser parts most likely to fail. A broken dispenser lever is the most common cause because it can keep the detergent door from opening or closing correctly during the cycle. Next, check the detergent dispenser cover, the detergent container, and the dispenser lid for cracks, warping, or other damage that can stop the soap from releasing. If one piece is damaged and you would rather not take the dispenser apart, replacing the complete detergent dispenser is often the simplest fix. A failed control board can also cause a Haier dishwasher detergent dispenser not working problem by not sending voltage to the dispenser, but that is much less common and should be ruled out last. If your Haier dishwasher soap dispenser not opening or your dishwasher detergent door not opening is leaving soap behind, inspect these parts closely for wear or binding. To get the exact replacement part for your specific dishwasher, enter your model number on RepairClinic.com and match the right dispenser lever, dispenser lid, detergent container, detergent dispenser cover, complete detergent dispenser, or control board to your machine.

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