It is frustrating when your electric water heater fails to provide hot water. If your electric water heater isn’t heating, it could be due to a range of simple or more serious issues.
The reasons can be a degradation in power supply, a malfunctioning thermostat, defective heating elements, sediment buildup, and more. Whatever the reason, your water heater needs a thorough inspection to get it working again.
Let’s learn why your electric water heater isn’t heating and how to restore its functionality.
Possible Reasons and Fixes For Electric Water Heater Not Heating Water
Before getting details, check the table below, highlighting all the probable reasons for your electric water heater’s no hot water issues with instant fixing ideas:
Potential Reasons | How You Fix It |
Faulty power supply | Reset the tripped circuit breaker. Replace the blown fuse or faulty wiring system. |
Malfunctioning thermostat | Inspect your electric water heater thermostat setting to see whether it is adjusted correctly. Replace the faulty thermostat. |
Hard water mineral buildup | Flush your water heater |
Bad heating elements | Replace the bad heating elements. |
Major Reasons For Why Your Electric Water Heater Not Working?
Is your electric water heater not heating up? Here are the common reasons we often notice.
1. Degradation In Power Supply
A steady power supply is crucial for an electric water heater. Any fluctuation or degradation in the power supply can prevent the heater from functioning correctly.
Inconsistent voltage can cause the heater to fail intermittently or not work at all. This issue can arise from faulty wiring, a tripped circuit breaker, or problems with the main power source.
2. Malfunctioning Thermostat
The thermostat in your water heater regulates the water temperature. If the thermostat malfunctions, it can not send the correct signals to the heating elements.
It can result in water being too cold or too hot. A malfunctioning thermostat gives inaccurate temperature readings that will cause inconsistent heating performance.
3. Defective Heating Element
The heating element is essential for warming the water. If it becomes defective, the water heater will struggle to heat the water or fail.
Heating elements can wear out over time or burn out due to electrical issues. When this happens, the heater can’t generate the necessary heat to warm the water.
4. Sediment Buildup
Over time, minerals in the water can accumulate at the bottom of the tank, which leads to sediment buildup. It acts as an insulating layer between the water and the heating elements.
As the sediment layer thickens, the heating efficiency decreases, making it harder for the heater to maintain the desired water temperature. Sediment buildup can also cause strange noises and reduce the heater’s lifespan.
How To Troubleshoot An Electric Water Heater Not Heating?
Here are DIY steps to troubleshoot you can apply to resolve the issue.
1. Fix The Power Supply Issue
Ensure the water heater is receiving adequate power. Check the circuit breaker or fuse box linked to the heater. If a breaker has tripped or a fuse has blown, reset or replace it.
Inspect the wiring connected to the heater for any signs of damage or wear. Use a multimeter to check the voltage going to the heater. If the voltage is too low, contact an electrician to fix the problem.
2. Flush Out Your Water Heater
Sediment buildup inside the water heater tank can interfere with heating performance. First, switch off the power at the circuit breaker and turn off the water supply valve.
Connect a garden hose to the drain valve at the bottom of the tank. Place the other end in a floor drain or outside. Open the valve to let the water flow and clear out any sediment.
Close the drain valve once the water runs clear. Turn on the water supply valve and allow the tank to refill. Finally, restore power to the heater.
3. Inspect The Thermostat Setting
Check the thermostat settings to ensure they are correctly adjusted. Locate the thermostat panel on the heater, typically found behind an access panel.
Verify that the temperature setting is appropriate for your needs. If the thermostat is programmable, ensure it is programmed correctly according to your usage patterns.
Test the thermostat by adjusting the temperature settings and monitoring the heater’s response. If you suspect the thermostat is malfunctioning, consider replacing it with a new one compatible with your water heater model.
4. Replace The Bad Heating Elements
If the heating elements are faulty, they need replacement to restore heating functionality. To do it, turn off the water heater’s power at the circuit breaker and close the water supply valve.
Drain the water heater tank completely by connecting a garden hose to the drain valve and opening it.
Once drained, locate the access panels on the heater, typically found near the top and bottom of the tank. Remove the panels and any insulation covering the heating elements.
Use a multimeter to check the continuity of each heating element. If a component shows no continuity, it is defective and requires replacement.
