I think you may have a faulty Thermal Cut Out

A faulty TCO will have nocontinuity across the two terminals (The black thing on top of the heating tank)

Therefore a good TCO will have power atboth connections and a faulty TCO will have power at only one.

(The function of the TCO is, if the waterover heats it cuts the power off to theelements)
