Why is Your Hot Water Heater Not Working And How To Fix It

There’s nothing quite as frustrating as turning on the tap, expecting a soothing stream of hot water, only to be greeted with a blast of cold. If this scenario sounds familiar, don’t panic. Hot water heaters are essential household appliances that play an integral part in our daily lives, yet sometimes encounter issues. 

In this comprehensive guide, we will explore why your hot water heater might not be functioning and provide solutions to restore it back into service; whether that be hot water heater repairs or even installation.

Understanding the Components of a Hot Water Heater:

Before we dive into troubleshooting, solutions, and hot water heater installation process, it’s essential to understand its components. A standard unit consists of:

  • A tank where water is stored before heating.
  • Heating elements (burners), which heat the water directly.
  • Pressure relief valve to prevent overpressure within the tank from building up too rapidly.
  • And finally, a thermostat which regulates its temperature.

Now, let’s explore the common reasons your hot water heater may not be delivering the warmth you need.

Common Reasons Your Hot Water Heater Is Not Working:

Sediment Formation

Over time, minerals and debris from your water source may settle at the bottom of the tank, creating sediment buildup. This acts as a barrier between the heating element and water temperature control systems resulting in either lukewarm or cold showers.

Solution: Flushing the Tank to Remove Sediment

To effectively address this, begin by switching off both power and gas supply to your hot water heater, connecting a hose to the drain valve at its base and letting water run until clear water emerges. This process effectively eliminates sediment, restoring performance.

Pilot Light Problems

If you own a gas water heater, one of the most frequent problems can be an unlit pilot light. When this occurs, your heater cannot heat water effectively and could potentially stop working altogether.

Solution: Relighting the Pilot Light

Rekindle your pilot light by following your manufacturer’s instructions. In general, this requires switching your gas control knob to “pilot,” pressing down, and using either a long lighter or match to ignite it. After lighting it up, release the knob and set your desired temperature setting.

Thermostat Problems

Faulty thermostats can severely hinder your hot water heater’s performance. When it fail to function as intended,  it may not regulate temperature accurately.

Solution: Adjusting the Thermostat

Begin by reviewing and adjusting the thermostat settings to suit your preferred temperature. If there are persistent thermostat issues, it may require replacement; please refer to your manufacturer’s guidelines for this process.

 Leaking Tank

Leaks in tanks can be a serious safety risk that requires immediate action to address. Leaks may result from corrosion, improper pressure relief valve installation, or other internal problems.

Solution: Dealing with a Leaking Tank

After discovering any leakage, immediately disconnect both power or gas and water supplies to the tank. Contact a licensed plumber who can assess the extent of damage and recommend repairs or provide guidance on installing a new water heater if your unit is beyond repair.

Age of the Heater

Age can have a substantial effect on the performance of your hot water heater, with most having an eight to 12-year lifespan. If yours has reached this age point, it might be wise to replace it.

Solution: Knowing When It’s Time to Replace Water Heaters

Now let us see when it is the right time to replace the water heater. If your hot water heater has reached or passed its expected lifespan, it would be wise to replace it as soon as possible. Installing a new hot water heater not only ensures efficient performance but also peace of mind that the water heater won’t suddenly stop working on you unexpectedly.

Corrosion and Rust

Corrosion and rust may also contribute to your hot water heater malfunctioning, with its inner lining degrading due to chemical interactions between water and oxygen molecules in the environment. Corrosion may lead to small or large leaks within your tank resulting in either loss of hot water or potential property damage to your home.

Solution: Addressing Corrosion and Rust

As soon as corrosion has caused significant damage to a tank, repairs may no longer be an option and replacement may be the only viable solution. To prevent further corrosion from happening again, install an anode rod containing an oxidizing agent. An anode attracts corrosion-causing elements while sacrificing itself to protect the tank’s lining. Regularly check the anode rod and replace it as necessary so as to extend the lifespan of your hot water heater.
