Electric water heater element test procedure: this article describes how to test electric hot water heater heating elements, what readings to expect if using an ohmmeter. The water heater element is what heats the water up in electric water heaters. Diagnosing an electric water heater isn’t too tough. Turn off the power to the electric water heater and then use the multimeter to take a reading of the thermostat. On this water heater, the thermostat switch is between terminals 1 and 2. The elements do not heat up at the same time. All you need is some tools (screwdriver and multi-meter etc. ) Replacing a Water Heater Thermostat in 8 Steps. Most water heaters have two elements/thermostats. Leave one of the probs that are contacting the component face of the screw and put the rest of the test against the metal base that is appended to the component from where it enters the water heater. Testing is the only option if you want to determine whether or not one or both of them has failed. Testing the water heater thermostat involves the checking of the heating element also. Digital Multimeter; Screwdriver; Steps on How to Test a Hot Water Heater Element. Set a multimeter to test continuity. Before proceeding to water heater element testing, it is a must and the best precautionary measure to wear electric shock-proof gloves and check the circuit breaker box first. If your water heater is 3500-watt, the multimeter will read 16Ω while 4,500-watt will register between 12 – 13Ω.
