If a home has existing hook-ups and requires no additional work to connect the dishwasher to existing water and electric lines, installation costs up to approximately $150, according to CostHelper, as of 2015. Costs vary based on the installation services required.
An installation kit, which is typically required by the manufacturer, averages between $10 to $30. If there are no existing hook-ups to water and electrical lines, the installation cost ranges from approximately $150 to $2,000. The higher cost includes modification of kitchen cabinets, counter tops or sinks. Generally, installation costs for any standard dishwasher are similar. Because most GE dishwashers are Energy Star qualified, costs range between $20 to $50 a year to run the dishwasher.
