Hmm.. you did ground each of your e kettles with dedicated grounding wire correct? I would not rely on the the fact that the kettle is just resting on a steel plate as a solid ground.
you could do some tests via an ohm meter to check your resistance to ground thru the water, or pot, and then test directly within the panel and see what the difference is.
sidenote.. all that stainless is purty
