The cost of dishwasher pump replacement in the U.S. typically ranges from $150 to $400, depending on the appliance brand, model, and labor rates. The pump itself usually costs between $50 and $150, while labor fees can add another $100 to $250. If the pump replacement is part of a larger repair job, the overall price may increase. Additional factors influencing cost include the type of dishwasher (built-in or portable), accessibility of the pump, and location. It's important to hire a professional technician to ensure proper installation and avoid further damage to the appliance.
