Replacing an entire water heater will certainly solve the problem but that is an expensive dart to throw - considering a replacement element is a 20 dollar part at most and 15 minutes worth of effort to replace.
It will take longer to drain the tank than to replace the element(s). The wiring is simple and if there is any doubt killing the main to the house will ensure you have no power running to your heater.
