Welcome aboard. I assume you meant ESP8266 (as there is no EDP 8622 that I can find) and there are no obvious parts in core parts. So first thing to do is upload the sketch that you are using (the .fzz file, upload is 7th icon from the left in the reply menu) which would allow us to load the sketch and see what your problem is. If it is a part from the net (which seems likely) it may be broken, and the information in the sketch will allow me to fix it.
