Diagnosing and Fixing Electric Hot Water Heater Element Issues

Maintenance and Repairs

Copping a lukewarm dribble from the shower head when you’re expecting a toasty flow can be a real dampener on the morning routine, right? You’re not alone though – turns out that more than 40% of Aussie households cop these hot water hassles at one time or another.

No dramas, our guide’s chockers with simple troubleshooting and fix-it tips for sorting out those niggling electric water heater element issues.

Key Takeaways

  • If your shower’s giving you a chilly surprise, check the power supply and reset buttons on your electric water heater. A broken element or dodgy thermostat could be to blame, and a multimeter can help you find out if it’s time for a replacement.
  • Stinky water can mean bacteria having a party in your tank because it’s too cold. Crank up the heat to 60°C or more for an hour after flushing the tank to show those germs the door.
  • Limescale is like the unwanted crust on your elements; cleaning them with vinegar or descaler keeps your hot water flowing right and efficiently.
  • Spot a leak? Don’t just gawk at it – tighten any loose bits or swap out busted parts right away to keep things dry and safe around your heater.
  • Fiddling with the temperature dial on the heater can stop you from getting steamed up about erratically warm showers – aim between 120°F (49°C) and 140°F (60°C) for that sweet spot of warmth without scalding yourself.

Understanding Common Issues with Electric Hot Water Heater Elements

If you’re experiencing not enough hot water, foul odour, limescale buildup, leaks, or temperature issues with your electric water heater, there may be an issue with the heating element.

Not enough hot water

We often take a hot shower for granted until we’re hit with a burst of cold water. Running out of hot water too quickly can be frustrating, especially when you’re in the middle of soaping up.

This common problem might stem from issues with your electric water heater’s elements or thermostat. The heating element is like the heart of your unit, converting electricity into heat to warm up the water.

Let’s tackle this head-on; it could be a simple fix. First, check if there’s power to the heater and that no safety switches or reset buttons have been tripped. A malfunctioning element or an inaccurate thermostat setting usually causes an insufficient hot water supply.

Grab your multimeter and test both elements – if they show resistance, they might still work fine; if not, it’s time for replacements. Adjusting the electric water heater thermostat may also get your showers back to that steamy bliss we all enjoy without calling in professionals just yet.

Foul odour

If you detect a foul odour coming from your electric water heater, it could be a sign of bacterial growth in the tank. This can occur when the water temperature is set too low, allowing bacteria to thrive.

To address this issue, you can flush the tank and increase the temperature to 60°C or higher for at least an hour to kill off any bacteria. Adding hydrogen peroxide to the tank before flushing can also help eliminate odours.

Once you’ve addressed the foul odour, it’s important to monitor the temperature settings regularly and perform maintenance as needed to prevent future occurrences. By maintaining appropriate temperatures and conducting regular tank flushes, you can ensure that your electric hot water system remains free of unpleasant odours.

Limescale buildup

If limescale buildup is affecting your electric water heater, it’s important to address it promptly. Regularly descaling the heating elements can help prevent reduced efficiency and performance issues.

Use a vinegar solution or a commercial descaler to remove the limescale from the elements and ensure that your water heater continues to function effectively.

Additionally, keeping an eye out for any signs of limescale buildup and addressing them early on can help you avoid more serious problems down the line. Regular maintenance and descaling will ensure that your electric water heater operates efficiently, providing you with reliable hot water when you need it.


Water leaks can be a common issue with electric water heaters. Check around the base of the unit for any pooling or dripping. Use a torch to inspect for any visible cracks or corrosion on the tank, fittings, or pipes. Leaks should be addressed promptly to prevent water damage and potential safety hazards.

Identifying and fixing leaks is crucial in maintaining your electric water heater. Inspect all connections, valves, and fittings regularly to ensure they are secure and free from leaks. If you notice any signs of leakage, it’s important to address them immediately to avoid further damage or potential safety risks.

Temperature issues

If the water from your electric water heater isn’t reaching the desired temperature, there may be an issue with the thermostat. Start by checking the thermostat settings and adjusting them if necessary.

Make sure to also verify that the power source is connected and functioning properly to avoid any interruptions in heating. If you continue to experience temperature issues, consider testing the heating element using a multimeter for defects or malfunctions that may be affecting its performance.

To ensure a consistent hot water supply, it’s important to maintain your electric water heater by monitoring its temperature regularly and addressing any fluctuations promptly. Regular maintenance checks can help identify potential problems early on and prevent further issues with your system’s temperature regulation.

How to Troubleshoot Electric Hot Water Heater Element Problems

To troubleshoot electric water heater element problems, start by testing the heating element and checking the thermostat and voltage. Next, identify and fix any leaks, as well as adjust the temperature settings if necessary.

Testing the heating element

To check the heating element, turn off the power to the water heater at the circuit breaker.

Checking the thermostat and voltage

When checking the thermostat and voltage, first switch off the power to the water heater. Use a multimeter to test the thermostat for continuity. If there’s no continuity, it may need replacing. Next, test the voltage at the heating element terminals to ensure it matches the rating on your water heater. Ensure proper safety measures are followed when handling electricity.

Identifying and fixing leaks

If you notice water around the base of your water heater, it may indicate a leak. To identify and fix leaks, follow these steps:

  • Check all connections and valves for any signs of moisture or water.
  • Inspect the pressure relief valve for leaks and ensure it’s functioning properly.
  • Examine the temperature and pressure relief valve for any leaks or drips.
  • If you find a leak, tighten the fittings or replace any damaged parts immediately.
  • Monitor the area around the heater for any further signs of leakage.

Adjusting the temperature

To adjust the temperature of your electric water heater, locate the thermostat control panel. Carefully remove the cover to reveal the temperature adjustment dial. Turn the dial clockwise to increase the temperature or counterclockwise to decrease it. Make small adjustments and wait a few hours for the water to reach the new temperature before making further changes. Ensure that the water temperature is set between 120°F and 140°F to prevent scalding and promote energy efficiency. Regularly monitor and adjust the temperature as needed based on your usage and preference.
