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.
How can you tell if a heating element is bad?
Inspect the metal wire coil for any breaks in the wire. If the wire is solid and has no breaks in it, the heating element should be good. If the wire has a break in it, the heating element is defective.

- Step 2: Open the metal box cover.
- Step 3: Detach the insulation.
- Step 4: Confirm that the power is off.
- Step 5: Locate the endpoint of the elements in the open panel.
- Step 6: Note the reading of your water heater element.
How do I choose a water heater element?
When selecting element, buy same wattage or less wattage… keep volts the same. It is ok to install higher watt up to 5500 on 4500 watt heater if breaker is 30 amp and wire is 10 gauge. It is ok to install lower watt: replace 4500 with 3500 as long as voltage is same.
Are all water heater elements the same?
There are three types: screw in, bolt in and clamp in. They all have different wattage ratings and can work on either 120 or 240 voltage. Check your state and local codes before starting any project.
