Electric Water Heater Not Working? Don’t Panic, Here’s the Solution!
What To Know
- To check the heating element, turn off the power to the water heater and drain the tank.
- To remove sediment, flush the water heater by opening the drain valve at the bottom of the tank.
- The pressure relief valve is a safety device that prevents the water heater from exploding if the pressure inside the tank becomes too high.
Electric water heaters are an essential component of modern homes, providing us with a constant supply of hot water. However, when they malfunction, it can leave us shivering in cold showers. If your electric water heater is not working, don’t panic. This blog post will delve into the potential causes and offer troubleshooting tips to get your water flowing hot again.
Common Causes of Electric Water Heater Malfunctions
1. Tripped Circuit Breaker or Blown Fuse
The first step is to check if the circuit breaker or fuse associated with the water heater has tripped or blown. If so, reset the breaker or replace the fuse. If the issue persists, there may be a more serious electrical problem requiring professional attention.
2. Faulty Thermostat
The thermostat regulates the temperature of the water in the tank. If it malfunctions, it may prevent the water from heating properly. To test the thermostat, turn off the power to the water heater and remove the thermostat. Using a multimeter, check the continuity between the terminals. If there is no continuity, the thermostat needs to be replaced.
3. Broken Heating Element
The heating element is responsible for heating the water in the tank. If it breaks, the water will not heat up. To check the heating element, turn off the power to the water heater and drain the tank. Remove the heating element and inspect it for any damage. If there is any damage, the heating element needs to be replaced.
4. Sediment Buildup
Over time, sediment can build up in the bottom of the water heater tank. This sediment can insulate the heating element and prevent it from heating the water efficiently. To remove sediment, flush the water heater by opening the drain valve at the bottom of the tank.
5. Leaking Tank
A leaking tank can cause the water heater to lose water, which can lead to overheating and damage. To check for a leak, inspect the tank for any visible cracks or holes. If you find a leak, the tank will need to be replaced.
6. Faulty Pressure Relief Valve
The pressure relief valve is a safety device that prevents the water heater from exploding if the pressure inside the tank becomes too high. If the pressure relief valve malfunctions, it may not open when needed, which can lead to a dangerous situation. To test the pressure relief valve, lift the lever on the valve. Water should flow out of the valve. If water does not flow out, the pressure relief valve needs to be replaced.
7. Incorrect Wiring
If the water heater is not wired correctly, it may not function properly. To check the wiring, turn off the power to the water heater and remove the cover panel. Inspect the wiring for any loose connections or damage. If you find any problems, the wiring will need to be repaired by a qualified electrician.
Troubleshooting Tips
- Reset the circuit breaker or replace the fuse.
- Check the thermostat for continuity.
- Inspect the heating element for damage.
- Flush the water heater to remove sediment.
- Inspect the tank for leaks.
- Test the pressure relief valve.
- Check the wiring for loose connections or damage.
