Hot Water Woes: 5 Possible Causes of Your Water Heater Failure

A malfunctioning water heater can be a major inconvenience, especially if it happens unexpectedly. It’s important to be aware of the common causes of water heater issues so that you can quickly identify and resolve them. We explore each of these potential causes in more detail to help you diagnose and restore its functionality. It’s important to note that working with a water heater can be dangerous, so if you need clarification on the issue, it’s best to contact a professional plumber for assistance.

Power Supply Issue

It may only work if it is receiving power. Check if it’s plugged in and if there’s a tripped circuit breaker or a blown fuse. If the power supply is the problem, resetting the circuit breaker or replacing the fuse may solve the issue.

Thermostat Malfunction

If the thermostat is faulty, it may not be able to regulate the temperature of the water correctly. Check its setting and make sure it’s set to the desired temperature. If it’s not functioning properly, it may need to be replaced.

Sediment Buildup

Over time, minerals in the water can build up, causing it to lose efficiency and potentially lead to damage. If it makes a rumbling or banging sound, it could indicate too much sediment buildup in the tank. In this case, flushing the tank may solve the problem.

Heating Element Failure

If the heating element is not functioning correctly, it may not be able to heat the water. A faulty heating element may need to be replaced to restore the water heater’s functionality.

Gas Supply Issues

If your water heater runs on gas, check the gas supply to ensure that it’s not interrupted. If the gas supply is intact, the gas valve on the water heater may be faulty and require replacement.
