- Anodes. The life of your water heater rests in the anodes which work to prevent corrosion by allowing corrosion within the anode rod instead of the water heater unit (if the rod is doing is job properly).lectrical elements. When two metals come into contact with one another, galvanic corrosion can occur. With an electric water heater, galvanic corrosion is often a problem as the heating elements inside the water tank are made of steel that has a copper sheathing.

How to Determine Which Water Heater Element Is Bad? Turn off the power to the electric hot water heater. Some units are wired to plug into a wall socket, and power is shut off simply by unplugging them. Most units are hard wired directly into the home’s circuitry, so turn the breaker for the hot water heater to “OFF” at the home’s main electrical panel.. Remove the two wires connected to the water heater element and push them aside. Unscrew the mounting hardware with a screwdriver, slip the wires out and bend them out of your way.

How do I tell which heating element is bad when my water heater is still heating some of the water? Your water heater is filled from the cold water running in a tube to the bottom of the water heater. Since heated water rises, the top element just maintains the upper part of the water as the outlet hot side is on the top. So, If you start out with good hot water - and it starts to quickly turn cooler - you know the bottom element is bad + you can put your ear up to water heater and hear which element is on. I am with the person who said to change them both. Turn off incoming water supply - let off water pressure at another faucet.

- Testing Spa or Hot Tub Heater Elements. Good heaters elements between 4.0 and 5.5kw should have the following results: * 9-12 ohms of resistance. * good continuity. * draw 15-25 amps at 240v. You test the element by using an Ohm meter, or any multi-meter will work also. Just place it on Ohms, at 1000, and place your test leads on each of the terminals (power to spa heater should be off). As mentioned above, a measurement of 9-12 Ohms of resistance usually indicates a good element.

What Causes an Element to Stop Working in a Water Heater? Like most parts, water heater elements have a finite working life. Continual cycling to satisfy hot water demand eventually wears out the element. Mineral deposits in the water hasten an element’s demise. The heating cycle causes dissolved minerals to solidify. They can coat an element, acting like a jacket of insulative material. In some cases, mineral sediment collects at the bottom of the water heater tank, encasing the lower element. Forced to work harder, the element eventually fails.

If the tank of the water heater is corroded, it needs to be replaced to prevent leaks and water floods. To extend the life of the tank you should drain the tank once a year and flush it out to remove all the sediments. This should be done after switching off the electric supply or the gas.

How to Know If Your Water Heater Is Bad With the unit off or unplugged, attach a water hose to the hose bib at the bottom of the water heater. The hose bib is for draining the water heater. Let the cold water fill the water heater as you flush out any sediments or mineral build up. Scheduling a water heater flush once a year can result in extending the life of your water heater. Annually check the pressure relief valve to ensure it is working. Wear thick gloves before lifting up on the test release lever atop the water heater. If it is working properly, hot water escapes via the overflow pipe.
