Melted Plug On Honda GC160 5.0 Pressure Washer

Need a part number to order a replacement for a plug that seems to have melted off my pressure washer.

So, I was setting up to use my pressure washer. Has a Honda GC160 5.0 engine. I check the gas and oil. All seems well. Fire it up. All seems well. Start pressure washer, and start using it normally, getting about 20 sqft of brick washed, but eventually I hear it sputter and, looking back, see it smoking. Immediately stop it and the plug on the side of the pump has melted off. Photos in link available on flickr dot com, photos, 26254575@N06, sets 72157634285583883 (Used commas to separate url, as I am being blocked)

Now, I need:
a) the part number for purchasing a replacement online.
b) a reason why this would happen?

Thanks.

Perhaps it's your thermal relief valve that melted. Need to look at a picture of the pump where it came off. I could not really tell from the picture of the part. Also the brand and model number off of the pump would be helpful as well.

Added a pic to the set. It was a clear, glassy plastic hex bolt, and used to be threaded. There seems to be a bead in it too.

Not sure what brand the whole pressure washer is, actually. The engine is a Honda GC 160 5.0. Engine is marked as GCAHA 1850007 QHC.

The only other marking I can see is the big, yellow "BE" on the handle to move the pressure washer around.
