Ohm Reading Low 3500 Watt 208 Volt Element

Did you notice a considerable drop in the temperature of the water supplied by your water heater? Every domicile needs hot water to carry out various firm chores.

However, it could be frustrating when your h2o heater produces lukewarm water that cannot serve the intended purposes.

While several factors can affect the effective functioning of your water heater, a faulty element is one of the most prevalent causes. Although professional person domicile electricians can troubleshoot and ready the problem, hiring 1 volition set yous dorsum in some dollars ranging from $75 – $250. Thus, the need to know how to test water heater element and replace the faulty ones.

In this commodity, we will show y'all step-by-step DIY guides on testing water elements with the utilize of a digital multimeter with no professional person groundwork in electrical works.

Tools Needed

These are some of the tools y'all should have handy before you commence your h2o heater chemical element testing:

Hand gloves
Screwdriver
Rubber goggles
Digital multimeter

Causes of Failure of H2o Heater Chemical element

Here are some of the possible reasons why your water heater element stopped working:

a). Accumulation of Mineral

Water heater elements have a express working life due to the abiding processes they undergo to give out hot water. These elements get weakened easily if there are mineral deposits in the h2o. The continuous process solidifies the minerals.

In some situations, the lower elements are wrapped with the mineral sediments which might cause the element to fail eventually. A good measure out you tin can take is by turning off your h2o heater and flushing your water heater every yr. Check our previous mail to learn how to flush a h2o heater.

If y'all can exercise this, the sediments will exist removed, and the life of the elements will be lengthened.

b). Trapped Air Pockets

All water heater elements must be operated immersed in h2o. The heat generated past an element can burn through its copper if non transferred to the water.

At that place is a need to bleed a line on the water to extract trapped air and sediments in the tank either one time or twice a yr. If this is not done, the trapped air 'Air Pockets' will make the upper element to burn down as it isn't immersed in water. This can cause a failure of the water heater.

c). Malfunctioning Thermostat

The office of a thermostat is to tell the elements when to heat the water apropos different temperature levels.

Whenever the temperature exceeds normal, the high limit switch on the thermostat is triggered, and the power will be shut down.

A malfunctioning thermostat will fail to command the heat supplied to the water heater element, which eventually causes it to burn.

d). Ability Surge

An element tin can also become burnt every bit a outcome of a sudden increment in voltage caused by a power surge or lightning. Each element has its own voltage rating, and any voltage higher up the required will burn the element.

east). Breakage of Heating Element

In an electric h2o heater, there might exist a loss of hot water when the heating element inside the tank breaks. Perhaps, the element might go burnt down, and the water cooling down slowly.

Simply if there is only cold h2o, it means the second chemical element has failed. Aside these three, a tripped excursion nor a blown a fuse might cause the heating chemical element to trip off. Checking the fuse box is too expected in this regard.

f). Bad Wire Connection

Elements receive electricity from heavy gauge wires. An chemical element might stop working if a wire slips of a terminal as a result of a bad connection. Problems such every bit arcing could also be caused as a result of this poor connection.

You should be conscientious attention to anything that can impairment your h2o heater chemical element, and ensure to steer clear of information technology.

Steps on How to Exam Water Heater Chemical element

Hither are the procedures for testing water chemical element:

Step 1: Disconnect from the power source

This is a very critical step in testing the water element. Locate the excursion breaker at the central electric panel that connects your water heater. It is usually situated in the metal box attached to the wall.

Nigh electrician marks each breaker with the proper noun of the gadget it powers. Identified the i marked with "hot water heater" and switch it off. If you are non sure of the breaker that works for your water heater, just power off the entire power source to ensure safety.

Pace 2: Open up the metal box embrace

Flip the metal encompass for the box opened. There, yous volition come across the panels held in place with screws to your h2o heater'due south side.

Nearly h2o heaters come with ane or two panels depending on their sizes. Unscrew the metal plate using a Philips head screwdriver. Ensure that the screws exercise not fall off to tiny places within your home.

Pace 3: Disassemble the insulation

Your h2o heater volition have a layer of cellulose or fiberglass insulation beneath the metallic cover based on its historic period. Disengage the insulation and keep it bated.

Use your safety glove and goggles while removing the insulation. Check the thermostat to see if it has a plastic encompass.

Pull out the tab to remove the thermostat plastic comprehend, every bit well. However, this is an optional procedure as some thermostats practice non come with removable plastic embrace.

Footstep 4: Ostend that the power is off

You should double-bank check to confirm that the power has been disconnected. Identify a noncontact voltage detector close to the wire that connects the element and the thermostat.

A beeping sound or flashes of light from the voltage detector indicates that the water heater is still connected to the electric supply. Ensure that the power is completely asunder before y'all continue with the work.

Step 5: Locate the endpoint of the elements in the open panel

Depending on the size of your home, your water heater will most likely accept one or two elements. Yous tin can't see the elements themselves as they extend deep inside the open console of the water heater.

However, y'all will be able to see their endpoints. An chemical element is around 1 inch long, and it'due south fastened to a plastic plate with the help of screws.

Step 6: Note the reading of your water heater element

Gear up the multimeter dial to the lowest or Rx1k, that is, resistances times 1000Ω. Await closely at the base of your water heater tank. Yous will see the inscribed wattage and ohms.

If your water heater is 3500-watt, the multimeter will read 16Ω while iv,500-watt will register between 12 – 13Ω. For water heater with a v,500-watt element, y'all will go between 10-11Ω.

Step 7: Use a digital multimeter to read the water heater chemical element

Place one of the multimeter probes on a screw fastened to the confront of the element. You can do this by unraveling the loose end of the metal element. The water heater element has no terminal, so you don't have to worry about which one to exam first.

However, ensure that information technology's the element alone you are testing and not the other electrical parts that connect to the elements. Connect the multimeter prongs to the tip of the chemical element spiral.

Check the readings on the multimeter and see if information technology correlates to the ones specified to a higher place. If the resistance reads very low, like 1Ω or doesn't read at all, that shows the water chemical element is faulty, and you should supplant it.

If you lot are not familiar with how to use a digital multimeter, here is a video that will show you the necessary procedures.

Check the reading for the 2d water heater chemical element also. In that location are cases where both elements and faulty and demand replacement.

Pace 8: Reattach the disconnected parts

Reconnect the wire to the water heater elements' surface. Also, comprehend the exposed panel, and use the plastic to cover the thermostat. Tighten the replace wire and reinstall the loosened screws.

Fix the insulation back, and turn the excursion breaker on. Y'all will accept to wait for few minutes for the water to heat up if yous replace a faulty chemical element.

How to Supplant an Electric H2o Heater Heating Element

Replacing a h2o heater element is quite a simple task. You lot can watch the video on how to do that.

Conclusion

Now that you accept understood how to test the h2o heater element, you should be able to troubleshoot a failure in this vital home equipment.

Remember, you only have to follow the following procedures:

Plough off the power
Open the metal cover to proceeds access to the chemical element
Detach the insulation
Read the resistance of the h2o element with a multimeter
Supervene upon the element if faulty
Put all the disconnected parts in identify
