Before you take any of the covers off of an electric water heater. MAKE SURE ALL THE POWER IS OFF. Warning just because you turned the breaker off, does not mean the power is off. I have seen, more often then not, Circuit breakers and fuses marked wrong. Even when they were marked by licensed electricians. I have seen where a breaker or switch only turns power to 1 leg of the power off, leaving 1 leg still hot. Most common mistake made is. "It's not making hot water so the power must be off!" This assumption can cost you your life. the power must be checked with a power reading meter that can read 240 volts. If you do not have one and do not know how to use one. Call a professional. Your Family will thank you. Electric water heaters are the most inefficient heaters on the market, they cost the most over the course of the year and there recovery is the slowest of all other types of water heaters.

Below I will go through each step to help you troubleshoot what is going on with your electric water heater.
Note: depending on the age of the water heater and the hardness, and other elements that make up your water. It may be cheaper and a better idea to just go ahead and replace your electric water heater. Example. If you have hard water, And it turns out your lower element has burned out. You may find that once you remove (or try to remove) the lower element, the whole bottom of the tank is full of lime build up and you can't get the old one out. or you can get it out but you cant get the new one in. And even if you could it would just burn out again from sitting in all that build up.
