Touch a probe on the multitester to each screw on the element. If you get no reading, or a maximum reading, the element is bad. Elements do have some resistance, so a reading of 10-16 ohms is normal, with higher ohm readings for 3,500 watt elements and lower readings for 5,500 watt elements.
Considering this, do gas water heaters have a heating element?
Instead of electrical-resistance elements, gas–fired heaters have a burner that's fed gas through a control valve and a thermostat switch. Because fuel-fired heaters heat the tank, which in turn heats the water, there will be more wear and tear on the tank than with electric heat.
