What causes a heating element to burn out in a water heater?

What Causes a Heating Element to Burn Out? Only electric water heaters rely on heating elements to warm up the water in the tank. Heavy gauge wires provide electricity to the components of your unit, so a poor connection between the wires and the water heater could result in the element giving out.

Will a water heater work with one element?

Yes, a water heater can still run if the bottom element quits. In most water heaters, the top heating element controls the thermostat and will still work even if the bottom element fails. So provided the top heating element is working, it can still produce some hot water even if the bottom heating element fails.

How many volts should a hot water heater element have?

The label on the water heater indicates what voltage the water heater requires. Most residential units are 220/240 volts (but some are 110/120 volts). Verify your water heater is getting the correct voltage. If it is not getting the required voltage, there are probably issues with your home’s electrical system.

How many ohms should a heating element have?

Check the resistance of the upper heating element using a multimeter. Measure the resistance between the two screw terminals on the upper heating element. A good element will have a resistance between 5 and 25 Ohms.

Should you get continuity through a heating element?

If you still get infinite resistance or zero resistance then the heater element is probably shot. In sum, if there is “continuity” through the heating element it is working. If there is no continuity (no electrical current can flow) then the element has failed.

How do you troubleshoot a water heater element?

Start by ruling out power problems. First, reset any tripped circuit breaker, and replace any blown fuse. Next, check if power is being supplied to the electric water heating element thermostat. Test the element, and if it’s faulty, replace it.
