The EdgeStar Combo Washer Dryer is designed to sense various conditions that may prevent the unit from operating in a safe and efficient manner. E37 is a temperature sensor error. When the unit cannot properly detect the internal drum temperature it will not be able to proceed with its drying cycle and will display the E37 error code.
It is recommended that you power the unit OFF, unplug the unit and wait 15 minutes and then power the unit back ON. Oftentimes, this will reset the built in electronic controls and reset the machine.
If problems persist, please consult with an authorized technician or contact EdgeStar service at 800-297-6076. Please have your model# and serial # available.
