Hey there David! It’s almost always the steam boiler element. You can check resistance across the terminals of the element (power off, wires removed), but this frequently fails to diagnose the element. It’s often the case, much like you describe, that the element doesn’t short until it’s hot, thus giving a false negative when cold. I suppose you could have the case off and once it heats/shorts, quickly power down and remove wires to test. If memory serves, “normal” would be in the low teens for ohms.
But I’d bet dollars to doughnuts it’s the steam element. And yes, removal is a pain, but you can do it. Hardest part is securing the boiler in a vise without damaging it. Best of luck!
