      I have a 9yr. old electric State 510e water heater. For the last 6yrs it would intermittently get real hot and throw the HI temp. cut off on the thermostat. I have replaced the thermostat twice and it still happens. I have flushed the tank every 2 yrs. Do I need to change the heating element? Any suggestions.
      Thanks

      Most (but not all) elec. w/h have an upper and a lower thermostat. Change the one you have not yet changed. Keep in mind that they must be clipped into the holder so they make good contact with the tank.
