This, based on the information given, if I was to walk into the same situation, I would pump the circuit down, check the strainer, if clean swap the power element. Very rarely have I had to change the valve unless the strainer is inaccessible or power element cannot be changed.

Now, id like to know what scientific evidence do you need to change a power element vs changing a TXV?
