Hi,not too sure what really prompted the problem. But you will need to still check for more posible places on your water heater to really know what causes it not to respond.
How Do I Troubleshoot My AO Smith Electric Water Heater
Troubleshooting and repairing an AO Smith electric water heater only takes a few minutes, and can save you hundreds in service calls and plumbing bills. The main indications of electric water heater problems are; no hot water, not enough hot water, slow hot water recovery, overheating and loud or unusual noises. Each of these problems has its own cause and repair requirements. We recommend calling a professional; however, you can repair most hot water heater complications yourself. Remember, if your water heater is still under warranty, or you are not sure, call the 1-800 number on your AO Smith water heater and ask for help and parts free.
Make sure the main electric circuit breaker(s) or fuses are in their "On" position inside the home's main electric panel. If a breaker(s) looks to be half on and half off, close the breaker and open it rapidly. If the breaker does not stay in the on position, replace the water heater breaker(s) and/or inspect the wiring from panel to heater. We recommend contacting a licensed, bonded and insured electrical contractor to troubleshoot the problem. In some cases, a bad breaker is a sign of trouble within the wiring system or water heater itself.
Testing AO Smith Electric Water Heater Thermostats
Turn off all circuit breakers and/or disconnect the fuses. Remove the thermostat cover plate(s) with a Phillips screwdriver. Turn the power back on.
Check for incoming power using a voltmeter. Set the meter to read 250 Volts. Touch and hold one lead wire to each of the top left and right screws of the top thermostat (or top two screws of the lower, if only one thermostat is present.) The meter should read approximately 210 to 230 volts of electricity. If no voltage is present with the breakers and fuses on, contact an electrician.
Turn on all the hot water faucets in the house until the water runs cold. This will ensure that the thermostat(s) will call for heat. Turn the faucets off.
Place one lead of the voltmeter on the top left thermostat screw and one lead on the second screw down on the right side of the thermostat. There should be 210+ volts of power. If not, turn the power off to the heater and push in firmly on the red reset button in the middle of the thermostat. You should here a click (but not always.)
Turn the power back on and check for voltage again. If no power, or limited power- fewer than 210 volts are present, check the top water-heating element for proper operation. If full power is present, but you still have no hot water after an hour or two, replace the top heating element. If no voltage, replace the thermostat.
Testing the AO Smith Electric Water Heater Heating Elements
Turn the power off to the water heater; remove the cover plate(s).
Test for incoming voltage with your voltmeter. Do not proceed until you verify that no voltage is present.
Loosen the two screws on each side of the heating element with a Phillips screwdriver.
Wearing heavy, electrical certified gloves remove each wire from the heating element and bend it slightly back out of the way.
Set your multi-meter to the Ohms position.
Place one lead on each screw of the element. The Ohm or resistance should read 12 to 16; averages are 13 to 14. If the reading is below 12 ohms of resistance, replace the water-heating element.
Reinstall the element's wiring.
Turn the power back on and test the circuit again. Reset your voltmeter to 250V. Full power should now be present. Turn the power off and replace the front cover(s).
Turn the water heater power on and wait an hour or two to check the hot water temperature at several faucets. The recovery time of an average AO Smith residential elect water heater is around 22 gallons an hour. It may take a while to reheat, depending on the size of your unit;
20 gallon 1 hour
30 gallon 1-1/2 hours
40 gallon 2 hours
50 gallon 2-1/2 hours
60 gallon 3 hours
80 gallon 4 hours
120 gallon 6 hours
Not enough Hot Water:
Calcium and other mineral buildup on a gas water heater control-valve thermostat probe will limit the heat detectable. You can clean the thermostat by removing the control valve and soaking the probe in a tall glass of white distilled vinegar and a little backing soda. Do not immerse the control valve itself; you will ruin it. Soak it for about an hour, and then rinse will with tap water before replacing.
Pilot light will not stay lit:
The most common issue with pilot lights is the thermocouple. The thermocouple is the thin copper wire, that when heated at its tip, creates a small electric charge that opens the magnetic safety valve inside the main gas control. Gas, water heater thermocouples do fail from time to time and need replaced. Older water heaters with accessible burner chamber doors are the easiest to work on. New water heaters are required to have sealed inner chamber doors and are not readily accessible. Only certified brand technicians should remove these doors. Each time the doors opened, you must replace an airtight seal. Failure to replace the seal could lead to carbon monoxide leaking from the water heater causing carbon monoxide poisoning.
The water heaters gas control valves and thermostats can also go bad. Replacing the control valve is just as critical a safety concern. If the pilot tube, and main burner tube, is not attached to the control valve correctly, gas leaks can occur.
Electric Water Heater Troubleshooting
Trouble shooting electric water heaters requires a bit of electric know how. Learning how to use a voltmeter, or multi-meter and becoming acquainted with your home electric system is most important when fixing an electric water heater. Failure to follow safe electrical practices can cause injuries and property damage.
When troubleshooting an electric water heater, keep in mind, there are only a few parts to its operating system: the heating element(s), thermostat(s), the main wiring connection junction, anode rod(s), water connections, T&PR valve, drain valve and the tank.
The most honest recommendation when repairing an electric water heater is this. Replace the thermostat(s), and the element(s), both upper and lower, if applicable, at the same time. Replacing one element or one thermostat of an electric water heater at a time causes a mismatch in the operating capacity of each part. Kind of like only replacing one battery in and electric device, it puts more of a strain on the older parts and causes premature failure. This leads to more frequent and costly repairs. Replacing all the parts at one time will help prevent future hot water heater problems and unnecessary water heater maintenance.
Water Heater Leaking
Water heater leaks are also an issue when troubleshooting a hot water heater. In most cases, you will need to replace the water heater. However, there are times when the leak is no coming directly from the water heater's tank. Leaks can also occur at a number of the water heaters connections. Before you replace your water heater, take the time to check of these locations:
Temperature and Pressure Relief valve (TP&R)- The brass safety valve usually located on the top, or near the top of water heater.
Finding Water Heater Repair and Replacement Parts
Finding water heater repair and water-heater replacement parts is not always so easy. Electric water heater repair and replacement parts are at most hardware stores, home centers and online retailers. Residential electric hot water heater repair parts are generally generic in by nature. New high efficiency, water heater parts like the ones for hybrid electric water heaters will only be available from their respective manufacturers until there is a need in the market place.
Hot water heater parts for gas hot water heaters are harder to find and often-difficult purchase. Many wholesalers will not sell gas repair parts or equipment to none licensed nonprofessionals. They feel there is a safety risk involved. However, there are online retailers whom do not see a need to limit their water heater parts sales. This is good for us, not so good for water heater companies.
