When your hot water suddenly disappears or your unit starts acting up, knowing how to perform basic electric water heater troubleshooting can save time, stress, and even money. While some issues require a professional plumber, others can be diagnosed—or even resolved—with a bit of know-how.
At All About Plumbing & Septic, we’re here to help you understand what might be going wrong with your system and what steps you can take before calling in the experts.
Common Electric Water Heater Problems
If your electric water heater isn’t working properly, it’s usually due to one of these common issues:
- No hot water
- Water that’s too hot or too cold
- Strange noises coming from the tank
- Leaks around the base
- Discolored or smelly water
Each of these symptoms can point to different underlying causes. Let’s break down what to look for when electric water heater troubleshooting.
1. No Hot Water? Check the Power First
Unlike gas models, electric water heaters rely on electricity to function. If you suddenly lose hot water, start by checking:
- The circuit breaker: Has it tripped?
- The reset button on the heater’s thermostat (usually behind an access panel)
- The unit’s power supply and any connected fuses
If everything appears to be working but there’s still no heat, the issue may be a faulty heating element or thermostat.
2. Inconsistent Water Temperature
Water that’s too hot or too cold can signal:
- A malfunctioning thermostat: It may need to be replaced or recalibrated.
- A broken heating element: One of the two heating elements may have failed, reducing efficiency.
- Sediment buildup: This can insulate the element and cause temperature fluctuations.
For accurate electric water heater troubleshooting, always turn off the power before inspecting internal components.
3. Strange Sounds From the Tank
If you hear popping, crackling, or rumbling noises, it could be due to mineral buildup on the heating elements or tank bottom. This is especially common in areas with hard water.
Flushing the tank can often resolve this issue, but if left untreated, the sediment can lead to overheating, reduced efficiency, or even tank failure.
4. Leaking Tank or Water Around the Base
Leaks should never be ignored when you’re completing electric water heater troubleshooting. Common causes include:
- A loose drain valve
- Leaking pipe connections
- A cracked tank (usually due to age or corrosion)
While some leaks can be fixed by tightening connections or replacing valves, a cracked tank often means it’s time for a full replacement.
5. Rusty or Smelly Water
If your water smells like rotten eggs or has a rusty tint, this could indicate:
- A failing anode rod, which is designed to prevent corrosion inside the tank
- Corroded tank lining
- Bacterial growth inside the heater (especially with infrequent use)
Replacing the anode rod or flushing the system can help, but persistent issues may require professional service.
When to Call a Professional
