Electric Water Heater

Electric water heaters operate reliably for years with few complaints. If you find yourself with little or no hot water, troubleshooting is in order. Start with the obvious -- is the power on or has the breaker tripped? If it's not a power problem, turn the power off and remove the access panel (or panels) on the side of the heater and locate wires and screw terminals. Check all terminals with a voltage tester to ground before proceeding.

The heating element is typically round or square, about the size of a matchbook, and has two screw terminals with wires attached. Loosen and remove one wire and check the element for continuity with a continuity tester. If there is no continuity, the element is probably burned out and needs to be replaced.

They can also collect sediment in the bottom, and air in the top.

Use the pressure relief valve on top to remove any air, usually once a month for a few seconds will do it. This should be set up to drain outside, btw.

At least once a year you should hook a hose to the drain valve at the bottom of the heater and let the water run out until clear.

If you have heavy iron in your water, such as in a well, this will coat the inside of the heater over time, and of course the elements, making them less effective. Turn off electric, drain the tank, and remove and clean the element carefully, then replace, refill, and turn on power. If that doesn't do it, replace the corroded/coated elements.

Replacing Water Heater Elements

If you have determined that your water heater element is burned out, replacement is usually straightforward. First shut the power off to the water heater and double-check it at the elements. Next shut the water off and drain the tank. Remove the offending element. Be aware that some elements screw in and some are held with screws. The screw-in type may require an element socket.

Take the old element with you to the hardware store to insure a proper replacement. Install the new element, fill the tank, check for leaks and replace the covers. Turn the power back on and you're back in business. Remember: if you're unsure about working with electricity, seek qualified advice or help.
