Hello-Thank you for taking the time to review your dishwasher. We do apologize that a normal wash cycle is taking longer than you expected. It is normal for dishwashers to run for up to two hours or more under certain conditions. Cycles times vary because of the clean sensors due to the sensor extending or decreasing cycle time and number of fills based on the soil level. Dishwashers now run longer to ensure good wash performance, but they use less energy while running. Also, in using less water, your water heater does not need to provide as much hot water and therefore is not using energy to heat more water. We hope this helps. Thank you for being part of the GE Appliances family.-Krystal@GEAppliances
