Actually we are still waiting on the very a respected company to chime in... ECS.
I'm sure Kram will email and get to the bottom of this as he is our ambassador and contact to them. Until they have their say
Kram will always be right, have the last word, and the rest of us wrong. 
Besides who gives a poop about the OP and and what his concerns are?
(lol, hope you know when I'm joking...)
But in all honesty I think the pressure sensor and pulling the pan to look at the trap doors and pickup is a good start...
That is if Kram says its okay.
