   a water heater has 5 parts to it….the tank of course then….on a std house unit it will have 2 thermostats ( top and bottom) then 2 heating elements (top and bottom)…..NOW when u first turn on a water heater power is sent to the top element heatingp the top half of the heater since that is where the hot water comes from…..now when u pull water from there the new cold water comign in goes to the bottom of the tank thru a diptube mang the bottom return on first making it run more……So most likely it is ur bottom element that has gone out but since ur going to have to open the panels to replace it might as well do both while ur at it so u wont have to do the next one in a month or two….

   Disconnect the power, then disconnect the wires going to the heating element. Ohm it out with a meter and see if it’s open. I vote for the top one as most heaters with 2 t-stats work the top first, then the bottom…
