    Ao Smith Warranty Information

    The AO Smith warranty is not a standard across-the-board warranty. It varies in terms and conditions based on the type, size, and series the water heater belongs to. The Signature Series models have the lowest warranty coverage, which begins at 6 years and goes up to 10 years.

    These warranties are the most common where there is full coverage against defects, damage, or other problems for up to 3 years. The remainder of the warranty is prorated with an increasing portion of owner responsibility after each year passes.

    The ProLine Series has higher warranty limits, up to 12 years. However, the individual units will vary in their coverage based on size, type, and who performs the installation. You will need to contact your installer for the warranty information, coverage, and any warrantied repairs or service calls.

    In all cases, you will need your AO Smith serial and model numbers. These numbers are clearly printed on the rating plate on the front of each unit.

    How Durable Are Ao Smith Water Heaters

    AO Smith set the standard back in 1939 for producing reliable, long-lasting water heaters that also have your safety and the environment in mind.

    Here are a few features built into all AO Smith tank water heaters.

    • Glass-Lined Tanks Fusing glass into the metal tank provides an extra layer of protection to the stainless steel core. This layer keeps heat inside the tank, protecting it from the corrosive effects of water. In 2004 the company introduced its patented Blue Diamond glass coating on its Conservationist® residential water heaters. This patented coating provides twice the corrosive protection compared to other brands.
    • Product Preservers Powered Anode System Anode rods take a beating from the corrosive effects of water mixing with metal. In the most basic terms, the anode rod will rust instead of your tank rusting. A.O. Smith redesigned their anode system to use adaptive technology that eliminates the need to check and replace the original style anode rods. The new anode system control module fits any standard 120-volt wall outlet and comes with a LED fault light and audible alarm.
    • Energy Cut Off Switch All A.O. Smith water heaters come equipped with a high-temperature cut-off switch. Should the water in the tank rise above the set temperature, it will automatically shut off.
    • Dual Heating Elements These elements provide a quick recovery time when hot water is in high demand.

    Why Choose Ao Smith

    When looking for a new water heater, either for replacement or as part of new construction, there are definitely advantages and disadvantages to all brands. What sets AO Smith apart, though, is detailed below.

    Eco-friendly Units

    With the exception of possibly Bradford White water heaters, AO Smith has one of the largest lines of eco-friendly options.

    Their plants are always updated, and manufacturing is as green as possible in every instance. This results in a cleaner output, higher efficiency, and greater value overall for everyone involved.

    Wide Variety of Sizes

    Unlike some smaller brands, AO Smith can push out various sizes, capacities, and types of water heaters. For example, you can find small, tankless designs made for a single room or large, multi-family tank models made for condos and apartment buildings.

    When you know what size you need for your family’s hot water, AO Smith will be ready with an option or two for you to choose from.

    Energy Star Certified

    We all look to save money, and investing in a name-brand system means a higher upfront cost in most cases. However, the name brands like AO Smith mean you get better fuel usage, less waste, and higher heat retention. All of those works together to bring your energy efficiency up and your annual utility bills down.

    Safety Features

    Lengthy Warranty

    Ao Smith Water Heater Reset Button

    In the United States, A.O. Smith gas and electric water heaters are quite common. Rinnai and Rheem are their main competitors in terms of brand recognition. One of the factors that leads many home owners to choose the brand is its dependability.

    When having a hot shower or using your washer, you may occasionally encounter a situation in which there is no hot water available. One possible troubleshooting option is to try to reset your hot water tank.

    The A.O. Smith water heater reset button is not immediately visible.

    Manufacturers design access to the button for safety and to prevent accidental activation. The location of the button may also be influenced by the type of hot water tank you have, whether it is gas, electric, or tankless.

    This article will show you where to find the A.O Smith water heater reset button.

    No Water Or Not Enough Hot Water

    If you are not getting enough hot water from the heater, confirm that the power supply is okay. The main switch might be turned off, or the circuit breaker could be tripped. Also, the fuse might be blown. So, considering this, ensure proper power supply to the heater.

    You may also test this by pushing and holding the reset button for a few seconds. The voltage may need to be checked as well. If theres no hot water even after the voltage is okay, you might need to replace heating elements.

    If you see a sudden interruption of hot water, then it may happen that the water usage has exceeded the tank capacity. So, wait a bit for the tank to be full again.

    Also, the tank might be undersized according to your needs. In that case, buying a new tank can be a good option.

    When the lower thermostat becomes faulty, the water wont heat enough. It must be replaced in this situation.

    Also, ensure that there are no improper or loose wire connections and that the thermostat is installed correctly.

    Ao Smith Water Heater Maintenance

    A.O. Smith Signature Premier 50

    Water heaters dont have a lot of issues and generally dont require daily or weekly maintenance. However, there are some tips to help you know when to do preventative maintenance and when to call a professional for assistance.

    You will want to read the owner’s manual that comes with your unit. If you have lost it or need another copy, the AO Smith Library has copies of most past and all current models available for download. The manuals will have troubleshooting guides and tips specific to your model and type of water heater.

    For other basic troubleshooting, we have a guide of the most common issues that arise with water heaters, their possible causes, and simple solutions you can check for.


    Pilot Does Light But Goes Out Right Away

    Gas is off, gas tube clogged

    Ensure gas is turned on and making its way to the pilot light. If gas is on but no flame ever develops, the tubes may be clogged and should be cleared or replaced.

    Leaking or Smelly Water

    High sulfate bacteria in the tank

    Soft water breaks down magnesium that creates sulfate gas giving the water a rotten egg smell. You will need to sanitize the tank or chlorinate the water. Contact a professional for pricing and details.

    Also, note that if you have the ICOMM Elite system, you will also have error codes on your app, browser, or on the display on the water heater.

    Ao Smith Signature Gas Water Heater: Design & Features

    If its a super smart and WiFi-enabled water heater youre looking for, then the A.O Smith Signature Gas Water Heater wont deliver. However, what you do get is a practical and affordable water heater that has everything you need and is ideal for families.

    The electronic gas valve allows you to alter the water temperature and its LED status indicator will help you to identify any issues. For simplicity, the ignition button allows for an easy start-up process.

    Helpful features include the in-built safety system, which will reduce the risk of flammable vapor being ignited. The anode rods inside the tank are combined with a ceramic tank shield to delay corrosion and extend the lifetime of your water heater. However, models such as the Westinghouse Electric Light Duty Water Heater do not require anode rods so if its something built to last a lifetime youre after, you could be better off with something else.

    Whilst this water heater only has a warranty of six years, one of the shortest in all the models we reviewed, the price tag on this model is one of the cheapest, making the shorter warranty seem fair.

    The lack of WiFi-enabled features means this water heater is not so sophisticated.
