Hi, my name isXXXXX am hoping that I will be able to help you with your problem today..
What parts did they replace?
Normally this is a bad heating element, if the tech checked it and replaced it, then he did not check to see if it is getting voltage to the heating element, this will cause the error code you received, so the problem is the thermostat that controls the heating element is bad, this is part number 661566, You can order the parts you need from the following places, http://www.apwagner.com/, http://www.repairclinic.com/, http://www.searspartsdirect.com/, or http://www.partstore.com/, all of these places offer easy returns and reasonable prices for their items.
