It’s possible for a water heater to show signs of malfunction. However, a catastrophic failure can occur as well. The issue may be a safety feature engaging or a part breaking. This happens with both electric and gas units as well as tank and tankless models. Understanding what’s occurring with your water heater can help you determine when professional assistance is necessary.

Problems With the Power Source

When power is interrupted, your water heater won’t be able to function. The problem may be a tripped breaker, blown fuse, wire damage, or loose connections. A professional can perform an inspection and determine what the necessary fix is.

Pilot Light Issues

Gas water heaters have a pilot light that powers the heating element. A pilot light can go out if there is a draft nearby or something touches it. If you relight the pilot light and it continues to go out, there may be a problem with the gas supply or thermocouple. While the water heater may appear to be functioning, no pilot light means there is no heating occurring.

Engaging a Safety Mechanism

Water heaters have several safety mechanisms that will shut the unit down to prevent unsafe conditions. Overheating sensors will shut down your water heater to protect sensitive components. Pressure relief systems prevent your water heater from bursting. Newer gas models have flammable vapor sensors that protect against explosions.

Extreme Buildup of Sediment

Preventive maintenance of your water heater should include draining and flushing the tank yearly. This process removes sediment before it can cause problems. If you skip maintenance and sediment/minerals accumulate, you can experience equipment failure. Sediment can cause a variety of problems, such as overheating and damage to heating elements.

Failure of the Thermostat

The thermostat on your water heater helps control water temperature. If this component fails, it will stop heating water. You may notice water suddenly feels cold and adjustments don’t help. You can avoid this problem with routine inspections of your water heater. The thermostat is a component that a professional will assess.

Interior Corrosion and Rust

There is an anode rod inside your water heater that protects the inside of your tank from corrosion. This rod requires replacement every few years for ample protection. If too much corrosion occurs inside your tank, components may fail. Corrosion can lead to the tank leaking to the point where replacement is necessary.
