4 Things you can do right now if you have an electric water heater, and no hot water….. or you can call us and we can do it for you!
To make things as easy as possible, I have tried to break things down into a few steps. Before you even consider trying to determine what is wrong with your “electric water heater”, you must have an electronic volt meter to properly inspect both controls. If you are uncomfortable with testing electrical circuits, please do not read any further and get professional advice.
Locate the electric panel in your home or condo and you want to find the breakers that are marked for water heater. Please note, just because it says “electric water heater” does not mean that it is accurate. In many cases, it may not be marked at all.
While the breaker is still in the on position, remove the upper plates on the tank, a flat head screw driver normally does the trick. On the top, you will see a black and red wire coming down providing power to the top control. Put your volt meter on the 2 screw heads and make sure you are getting proper voltage. If you are not, seek the help of an electrician to provide proper voltage to your controls. If you are getting proper voltage, turn the main breaker off, and proceed to step 3.
Confirm that the power is off by retesting for voltage. Now , starting from the top 2 controls, remove all the wires, and re-tighten the screws. Please note, take a picture 1st, to make sure that you put all the screws back properly. Use an ohm reader to test the bottom control, it should read between 11 to 15 ohms. Test the top control by placing your special meter on the screw heads on the left, if bulb gets bright, it’s working, if it does not, it needs replacing.
Now repeat those steps for the identical 2 controls at the bottom.
This is the fastest way that I know of to determine what is wrong with your “electric water heater”. There are still other things to take into consideration, such as…. how old is your existing water heater? Does it make sense to repair, or simply replace? If one of the failed parts went bad, does it make sense to replace the same upper or lower control part as well.
Part 2 of this equation is how much is your time worth? Just because you know how to “troubleshoot”, or “fix it”, does not always mean that you should. My last tip is that if the bottom of the upper, or lower control fails, it requires a special tool to remove. Please make sure to properly drain the tank first, and properly fill before turning the power back on.
