if an element is constantly expanding and contracting (if you keep switching the hot water heater off and on again) all the time it causes cracks and over time the water leaks into the element causing it to short which means you have to replace it.
Common problem. The heater grid burns a hole and the only fix is to replace the element.
How do you replace the heater core on a jimmy?
To test and replace a heating element: # Turn off power at the Electrical Service Panel and post a sign warning others not to turn it on. # Remove the access panel on the electric water heater. # Disconnect one of the element wires and set a multimeter to RX1000 (resistance times 1,000). Touch one probe to an element mounting bolt and the other to each element terminal screw, in turn. If the tester displays anything but infinity (open circuit), replace the element. # If necessary, set the multimeter to RX1 and touch the probes to the terminal screws. If there is any resistance reading at all (closed circuit), then the element is good. If not, replace it. Both upper and lower elements are tested in the same manner. # To remove the element, first drain the heater. # Disconnect the remaining element wire. Remove the mounting bolts holding the element in place. Remove the element. # Replace the heating element with one of the same model, shape, and rating. Make sure you also replace any installation gaskets.
Could be a bad heating element or a bad breaker, either of which can be fixed. The only reason to replace a water heater is if it is leaking. Anything else can be fixed cheaper.
A "heater" or a "heater core"?
