Hello! I completely understand your concerns with the washer having an issue with multiple error codes and an unresponsive screen. I'll be more than delighted to assist you with this issue. The error code Ae4 describes a communication error. Have you tried to unplug the washer and plug it back in?
If the issue still occurs the unit will require service: If the unit is out of warranty you can use the following link to find a local service center near your area. http://www.samsung.com/us/support/service/location.
If the unit is still under warranty you can message ant moderator http://bit.ly/2tCGnGK
