Our guide to A.O. Smith water heaters will explain common issues, provide tips on error code reading, and show you how to fix them.
The smell of combustion and sooting
If you start to notice blue smoke coming from your gas water heater, first make sure that there are no obstructions in the vents, flue baffling, and gas burners.
The venting path should be clean of any dirt, dust, or grime build-up. Preventative inspections and regular maintenance can help with this type of issue.
A buildup of carbon deposits, flue air leakage, and un-vented combustion products are major causes of this occurrence as well.
As small as this may seem, it’s actually a big deal if left unattended because un-vented products will eventually lead to soot build-up across the surface of your water heater. If the main burner or gas connection is loose, tighten it.
If the unit is using an incorrect size of the orifice, replace it.
If you’re facing a similar issue or question regarding safety or gas leaks within your hot water heater construction then we highly recommend seeking qualified professional advice with regards to solutions from a reputable company such as Integra Gas.
Burner won’t ignite or no hot water
The main burner won’t ignite because of pilot light problems. This can be due to a number of things such as a clogged hot surface igniter, a blocked gas line, or if the thermostat is damaged.
If a clog is present in the gas line – make sure to clean it out! You may have dirt and debris in your gas line that needs cleaning or if the pilot light lines are blocked you need to clean them out with tweezers or blow them clean with compressed air.
It’s also important to know that if there is corrosion in the system, it will make it difficult for the burner to light and therefore you should check for this possibility by periodically inspecting the gas control valves.
If nothing else seems wrong after attempting these options then try replacing your thermostat with a new one to make sure that wasn’t dysfunctional causing your ignition issue.
A lack of hot water and a slow recovery
Clean and drain your water heater tanks with an insulation blanket that will help the units keep heat in the house. Look at tips to help improve efficiency and then decide if you want to hire a professional.
Clean flue vents for any clogs or blockages. Replace vents, if needed. Flush pipes regularly by running hot water through them so that build-up isn’t left inside and reduces efficiency further.
Use a thermometer to confirm that the temperature is correct before using it for its purpose again on a regular basis.
Burner flame problems
If the top of the gas burner flame is turning yellow, then it indicates that air is being supplied to the water heater. This could be due to a blocked vent pipe or due to some other problem in the vent system.
You need to clean it thoroughly and make sure there are processes in place to ensure that the issue doesn’t happen again.
AO Smith Water heater won’t heat
Some gas water heaters have a thermocouple. The thermocouple detects the pilot flame and monitors the stove’s temperature. If it does not detect a flame, it will prevent the gas valve from opening to allow gas to enter the burner.
If the valve does not open, then the burner that is on top of it does not light and therefore your water heater will not heat.
Make sure you check to see if there are any fault codes showing on your display panel because if there aren’t then you need to first make sure that all connectors are connected properly.
And then ensure that your gas valve has pressure by putting in a new hose connector or a replacement part if needed to get around this problem.
Water heater leaking issue
A temperature and pressure relief valve open to keep the water heater from getting too warm or experiencing excessive pressurization.
The valve itself will open at a predetermined temperature level, one which is typically printed directly on the device in question.
If your temperature and pressure relief valve may still be leaking, then it’s possible that something may simply be lodged in its internal system, making it impossible for it to function as expected at this time.
The temperature and pressure relief valve should be replaced if it leaks even before it reaches the indicated relief temperature.
The AO Smith water heater is too hot
When the heating element shorts out, it will cause a short circuit, which will allow it to continue heating, causing the water to become too hot.
To determine if the heating element is shorted out, plug in a multimeter and test if the element, itself, is shorted. If it’s shorted out, unplug the machine and replace it with a new one.
The water heater is not lighting up
An igniter lights the gas in some water heaters. Make sure that the igniter is receiving voltage before attempting to light a defective igniter.
An igniter that is receiving voltage but does not glow indicates a defective igniter that should be replaced. When sufficient air reaches the pressure switch, it closes, causing the control board to turn on the water heater.
It is possible that your water heater won’t turn on right away if your pressure switch is faulty.
