Often asked: How To Test A Water Heater Element With A Multimeter?

How can you tell if a water heater element is bad?

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 many ohms does a water heater 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.

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.

Can you change a water heater element without draining the tank?

It is possible to change your water heater’s heating element without draining your tank. Although, keep in mind that it can be a bit more challenging.

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.

What happens when a heating element goes out in a water heater?

If you have an electric water heater, the heating elements inside the tank can break and lead to a loss of hot water. Sometimes, your water will slowly start to cool down and this could be because the element has burned out. If the second element fails, you’ll be left with only cold water.

What is the resistance of a 1000w heater marked for 230v?

The resistance of the heater is 52.9 Ohms.

How do you check the resistance of a heating element?

Testing A Conventional Element. Know the resistance of the element should be this can be calculated using known values: R = (V x V) / P [Where V is the voltage powering the element, P is the power the element uses and R is the resistance.]

How do I test my thermostat with a multimeter?

Test the Thermostat With a Multimeter Touch one of the meter probes to the R terminal (to which the red wire is attached) and the other probe to the G, W or Y terminal and note the reading. If the thermostat has power, the reading should be between 22 and 26 volts.

Should a water heater element have continuity?

If the ohmmeter needle moves or you get some Ohm reading (any resistance other than infinity) then the heating element is OK. 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.

Can a water heater element have continuity but still be bad?

If the test fails, the element is bad and will need to be replaced. There are no other choices, they cannot be repaired and there are no moving parts. You need to test both elements to see if they are both bad. Perform the continuity test on the other element to see if it is working.

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.
