What are the drawbacks to using an old GE dishwasher model?

The primary drawback to using older GE dishwasher models is that they are inefficient in comparison to modern dishwashers in both power and water consumption. An older dishwasher may also be more prone to needing repairs, especially if it has been in service for an extended period.

The Department of Energy estimates that a dishwasher built before 1994 wastes 10 gallons of water per wash cycle and at least 5 percent more energy than a newer dishwasher that meets the 2015 Energy Star standards for efficiency. This extra electricity and water consumption can add up quickly, increasing the utility costs for using an older GE dishwasher up to $35 dollars a year over a newer dishwasher.
