Had issues with my P2 low voltage took cover off to clean and looks like the wire melted of the exhaust housing looking at online video the wire should of been located through a hole supplied at rear but instead has been sandwiched through hosing and case rather than thru hole . 
So looks like need to replace the wire bit looks like the frame / case needs taking apart . Seen online vids the wire should of come thru the hole. 
Looks like whoever built machine put wire in wrong place !!! Helps how do resolve this .
