Here are some of the most common problems that we hear about when it comes to the water heater not working properly.
Electric Hot Water Heater Not Working After Power Outage
One possible reason for your electric water heater not working after a power outage is a tripped circuit breaker. If you had the power go out, when it was restored, the circuit breaker might not have automatically reset, cutting off the power supply to the water heater.
To resolve this, locate your circuit breaker panel and check for any tripped breakers. If you find one related to your water heater, switch it off and then back on to reset it.
Additionally, faulty electrical wiring or a malfunctioning electrical system can also prevent your electric water heater from working properly after a power outage. In such cases, it is advisable to turn off the power to the water heater before inspecting or working on the electrical components. If you are unsure about handling electrical repairs, it is best to consult a professional.

Electric Water Heater Not Heating Water
If your electric water heater is running, but the water remains cold, there could be an issue with the upper heating element or thermostat. The upper heating element is responsible for heating the water in the top portion of the tank. If it malfunctions, you may experience insufficient or no hot water.
Similarly, a faulty upper thermostat can prevent the heating element from activating.
To troubleshoot this problem, turn off the power to the water heater and use a multimeter to test the heating element and thermostat for continuity and proper functioning. If you find any faulty parts, they will need to be replaced to restore your water heater’s ability to heat water effectively.

Hot Water Heater Running When Not Using Water
If your hot water heater seems to run continuously even when you’re not using any hot water, there might be an issue with the high-temperature limit switch. This switch is designed to shut off the heating elements when the water reaches a certain temperature.
A faulty high-temperature limit switch can cause the heating elements to remain active, leading to your water heater running unnecessarily. In such cases, it is recommended to contact a professional plumber or water heater technician to diagnose and repair the problem safely.
Water Heater Pilot Light Keeps Going Out
For gas water heaters, a common problem we hear about is the pilot light going out repeatedly. Several factors can contribute to this issue, such as a dirty pilot tube or thermocouple. The pilot tube can accumulate dirt and debris over time, obstructing the flame and causing the pilot light to extinguish.
Another possible cause is a malfunctioning or broken thermocouple, which senses the pilot flame and controls the gas supply. If the thermocouple is dirty, bent, or damaged, it may not generate enough voltage to keep the gas valve open, resulting in the pilot light going out.
Regular cleaning of the pilot tube and ensuring the thermocouple is in good condition can help resolve these problems. However, if the issues persist, we say bring in the pros to take care of the problem.
Electric Water Heater Thermostat Troubleshooting
When troubleshooting electric water heater thermostat issues, a multimeter can be a handy tool. A multimeter allows you to measure the ohms of resistance and check the continuity of the thermostat and heating elements. If you find any components with abnormal readings or no continuity, they may be faulty and require replacement.
It is important to exercise caution when working with electrical components and always follow safety guidelines. If you are uncertain about performing electrical repairs, don’t risk it.
Water Heater Repair and Maintenance
Regular repair and maintenance are crucial for the longevity and proper functioning of any hot water heater. It is recommended to schedule professional inspections annually or as advised by the manufacturer.
During these inspections, a certified technician will examine the water heater, including the access panel, anode rod, drain valve, and the bottom of the tank, to ensure they are clean and functioning correctly.
In case you notice any signs of water damage or if your water heater is leaking, it is important to address the issue promptly. A leak may start small, but it’s the sign of a bigger problem, and could get worse quickly.

FAQs
How do I know if my thermocouple is bad on my water heater?
To determine if your thermocouple is faulty, you can use a multimeter to measure the voltage it generates. Follow the manufacturer’s instructions and compare the readings with the recommended values. If the readings are significantly lower than expected or there is no voltage at all, it indicates a bad thermocouple that needs to be replaced.
Why does my water heater pilot keep going out?
A pilot light that keeps going out can be caused by various factors. Common reasons include a dirty pilot tube, insufficient gas supply or pressure, a kinked thermocouple, or a faulty gas valve or main control valve.
How long does a thermocouple last?
The lifespan of a thermocouple can vary depending on the manufacturer and usage. In general, a thermocouple can last anywhere from 3 to 5 years. However, it is important to refer to the manufacturer’s instructions or warranty information for specific details about the expected lifespan of your thermocouple.
