American Standard Water Heaters - Page 3 - Recent Questions, Troubleshooting & Support

I had the same problem with a similar water heater at my old house, and it happened at about the same age. It ended up being a faulty electronic gas valve. I strongly recommend that you have a licensed gas fitter look at it. Gas appliances are definitely not DIY.

Verify that the flu is free of obstructions.
The center of the water heater should be a straight tube with a diverter in it to force the hot gasses in contact with the water tank. Once the exhaust gets clear of the water heater, it should have free flow outside.

Yes, if these plastic parts cover pipe thread or would stop the flow of water.
If the plastic parts simply sit around the pipe like a collar, then they do not have to be removed.
Red marks for Hot pipe
Blue for cold water inlet.
If your hot and cold are reversed, then water heater will not function.
In ordinary installation, cold water line has the shut off valve.

Hi,
Check the the ignition module is getting power... if not find out why not and fix that...

If the module is getting power and you are not getting spark then the module is bad... this is a common problem...
I think you will find that the module is the problem...

You'll have to disconnect the water lines from the top to pull the rod up out from within the tank. If you don't have enough clearance above the tank, you'll have to drain the tank, remove the venting and tilt it or lay it down to remove it. The sacrificial rods usually go bad prematurely on well water systems with hard water and causes a sulfur stench in your water. Here's a quick test to try before you do this: Go to the nearest faucet to the water heater and fill a glass full of cold water and another glass full of hot water and smell them. If the hot water is the only glass that smells like rotten eggs, it's most likely coming from your water heater due to your anode rod. Douglas

Relighting the pilot of any water heater is a pain. The first thing to do is call the water heaters manufacturer for information on your specific make and model. If your water heater is under warranty, they will provide technical advice and free parts.
1. Replace the water heater's thermocouple. Make sure the pilot flame is centered on the shiny end of the thermocouple; it requires a certain amount of heat to produce enough electricity to open the main gas control valve.
2. Replace the main gas valve control.
3. Replace the water heater; I know this not what anyone wants hear.

Yes it can be replaced. This is a temperature/pressure relief valve and is the second most important safety device on your heater. They rarely make racket. Is it leaking? if so yes replace it. Water heaters should have a portion of water drained annually along with operating the relief valve. IF you raise the handle a few times, and it continues to leak, then it should be replaced. If you replace it be sure to replace it with EXACTLY the same temperature and pressure rating that is on it now. Allow the water heater to cool, and drain pressure before removing. If it is rumbling inside, you might have calcium deposits bouncing around in the bottom. Drain some water and see how it looks. (Often if you operate drain, and haven't in a long time it won't reseal)

did you bleed the gas line?
you must loosen the connection at the water heater until you smell gas coming out, then tighten. wait at least 5 minutes before attempting to light. this will give time for the gas to dissipate
if it still wont light... are the connections to the thermocouple tight? if that is tight, might be a bad thermocouple, you will need to replace it.

use a long lighter to ignight the pilot

Bottom heating unit is probably burned out from overheating due to sediment in bottom of tank.

Usually a polarity problem is fixed by reversing the wires that run to the power supply to the unit.First, shut off the breaker that feeds power to the furnace. Most of the time, there will be one black, and one white Unhook those, switch the wires around, use new wire nuts to wire them back together. Hope this helps.

If it comes on and runs but will not continue to run, I would be looking at the flame detector. If the detector is faulty, doesn't see the flame, the unit things there is no flame and closes the valve.
