Whirlpool GEW9200LW1 dyer with an electrical short

[Mrfox769]

I have a front loading Whirlpool GEW9200LW1 that blows the circuit breaker as soon as I plug it into the outlet.  I have checked every wire and component for continuity and resistance.  I also visually checked every wire and circuit board but I cannot find any short.  I took the unit completely apart any pulled all the wiring.  I started with the main wire harness (WP8576530) installing it in the dryer without connecting the components.  When I plugged in the dryer, the circuit shorted out.  I found if I disconnected the ground wire attached to the bottom of the dryer between the out exhaust pipe and the heater, I can connect the dryer to the outlet without the tripping the circuit breaker. 

Any thoughts where the short might be?

What about the actual appliance cord or the wall socket? Is it possible there's an issue in either one of those that doesn't manifest itself until the dryer is plugged in?

I changed the cord twice and the outlet checks out.

Have you checked the heating element to see if its grounding out against the heater housing ?  or the motor may possibly be junk and drawing to much amperage for some reason.  When ever I run into an issue with any appliance that trips the circuit breaker I will always run a good extension cord to on a separate receptacle on a different breaker first and try that.  The majority of times I do that , its always been the wall receptacle that has the issue. especially if they just  installed one of those new arc fault breakers in the panel.  Ive seen dishwashers that run just fine pop those types of breakers.
