I have an Electrolux dryer that started giving this error code 4 days after I bought it. The service people can out and replaced the dryer element and the problem resolved but came back after a couple of weeks. I examined the dryer element removed from the dryer when it was replaced and found that the plate that runs through the center of the element that has the heating coils wrapped around it had warped on one end due to the heat. This same end isn't attached to the dryer element housing which causes the problem. This is a design problem with the heating element and the problem won't be completely resolved until they redesign the heating element.
