Tip & How-To about Plumbing
Most likely you have a bad heater, element or regulator, first turn off the breaker and look at the wires in the connector box on the heater, if they have no stripped insulation make sure the wire nuts are tight and are touching metal on the end of the wires, if there is insulation between the wires remove it.
Next remove the covers off the heating elements and with an ohm meter on ohms and power off disconnect one wire from heating element touch one end of the element to the metal on the heater and the other end of the tester on the heating element screw, check both screws for contact tact for this test, if you get a reading the element is bad.
This does happenon new heaters as well as old. Next try the bottom heating element taking off one wire and doing the same, if you get a reading there then it's the element that’s bad. Next touch the ohm meter to the two screws with one wire on the element not touching the one disconnected wire you should get a slight reading, the meter will move maybe an inch, however if it moves all away over to the opposite side it means the element is shorted out and will have to be replaced,
At this time if it does any of the above call the company you bought it from it's under warranty. Put it back together and let them replace it at no charge to you.
However if you want to fix it yourself them supplying the part turn off the heater water and power and drain the tank then buy the socket that fits the element then unscrew it and replace it with a new one. Once it is installed open the water valve on the hot side in the bathroom or kitchen depending whichever is closest and wait for all air to be out of the system.
Once the air is out then turn heater back on. Hydrogen sulfide gas can cause an explosion that is why it is important to have the tank full before turning on power to the heating element. This is especially so for gas operated heaters and where you have well water.
