Today, our plumbers walk you through the 5 signs your water heater is overheating and what to do about it.

The Common Causes of Water Heater Overheating

• A malfunctioning thermostat
• Stuck heating element
• Sediment buildup
• Faulty pressure relief valve
• Incorrect thermostat settings
• Faulty temperature sensor
• Poor ventilation
• Worn-out dip tube
• Electrical problems

While some of these issues are minor issues that you can resolve on your own, it’s important to know when to call a local plumber specializing in water heater repair. Most water heater issues are best left to experts who know what they’re doing.

• Extremely Hot Water from the Taps

One of the common signs of an overheating water heater is scalding hot water coming from your faucets or shower. While it's normal for hot water to be warm enough for comfort, it should never be so hot that it could cause burns. If you’ve recently had to adjust your water use due to extreme heat, it’s time to call a nearby plumbing service to carry out an inspection. A thermostat set too high or malfunctioning could be to blame.

• Popping or Rumbling Noises

If your water heater sounds like it’s boiling or making loud popping noises, that’s not normal. This sound usually comes from sediment that has built up at the bottom of the tank. When water gets trapped beneath the sediment, it overheats and creates those rumbling or popping sounds. Left unresolved, this can put stress on the tank and lead to overheating or even premature failure.

• Leaking Pressure Relief Valve

The temperature and pressure relief (T&P) valve is a critical safety feature designed to release excess pressure when it builds up inside the tank. If your water heater is overheating, the pressure may rise to unsafe levels and trigger the valve to leak or discharge water. This is not something to ignore. A leaking T&P valve is a clear sign that your system is under stress and may be dangerously overheating. Call a local plumber as soon as you can for professional assistance.

• Frequent Tripping of the Circuit Breaker (Electric Water Heaters)

Electric water heaters that overheat can trip the circuit breaker as a safety measure. If you find yourself constantly resetting the breaker after using hot water, your water heater may be pulling more power than it should due to overheating components like a stuck heating element or faulty thermostat. Call a nearby plumbing technician specializing in water heater replacement to find out what’s causing circuit breaker tripping.

• Burning Smell or Discolored Water

Overheating can sometimes cause electrical components to emit a faint burning odor, especially in electric units. You may also notice discolored or rusty water, which could indicate internal damage caused by excessive heat. These signs should be addressed in a timely manner to avoid further damage to the unit or risk to your home.
