Question about Water Heaters

1 Answer

Small seepage underneath hotwater heater.

Not sure of hotwater heater's age, but suspect it could be15 years or so. It is an A O Smith, model FSG 50 232. Its Energy Guide label makes reference to 1994 guidelines. My question is whether the seepage is an indication I need a new tank?

Soetimes its gaskets around flanges and heater element fixings that fail
have a good look round after drying the area with tissue etc.
leave a dry tissue round the based so you will see tell tale trace stains where its perhaps leaking from

AO Smith BTH 500 ignitor keeps burning out,is my electronic control the problem?


I would report problem to AO Smith.
Also ask question on pro water heater forum
http://www.thetankatwaterheaterrescue.com/forums/forum3/

AO Smith service handbooks:
http://www.hotwater.com/resources/product-literature/service-handbooks/
If the igniter is not turning off, then that would explain early failure, and it would be caused by the control chipset

On A.O. Smith water heater model BTH 199 100 where is the heat sensor rod located ?


Parts list:
http://www.hotwater.com/lit/partslists/197728-004.pdf
Flame rod, flame sensor sits next to igniter inside combustion chamber. This can be cleaned with sandpaper. Do not touch with fingers. Purpose of flame rod is to detect whether ignition has caused actual, sustainable fire inside the combustion chamber.
If sensor is bad, or no ignition is detected after 2-3 attempts, then 'no ignition' error is given.
Bad gas control valve, bad-or-dirty flame rod-sensor, low gas pressure, misaligned rod, dirty combustion parts, etc

Service handbook:

High gas pressure spikes can daMAGE gas control valve p7

To light the pilot on my OS Smith water heater, I follow the instructions in the label, but nothing happens, no hot water after one hour. Read that there is problems with water heaters, I have some...


Thank you for providing clear description of product:
Your water heater has intellivent gas control thermostat.
There are always problems with water heaters. It is a huge field.

1) Open following link for AO Smith service manuals.
I do not see service manual specifically for the GP series.
http://www.hotwater.com/resources/product-literature/service-handbooks/

2) Open following link to identify gas valve and download typical service manual:
Some AO smith power vent models have intellivent gas valve, and some have smart valve gas vent. Older models might have knob-type gas valve.

AO Smith Water heater FPSH50-260 keeps blowing fuses


FPSH series is a power vented residential gas water heater.

1) The blower is plugged into 120Volt outlet. If blower has short, then it will trip breaker.
Blower could be Fasco model 7021-10195, or 7021-10770. Call AO Smith: 1-800-527-1953. They will need model number and serial number located on label on side of tank.

2) Before calling AO Smith, check outlet with circuit analyzer. Outlet must have correct polarity and must be grounded. Unplug cord to water heater and run continuity test from ground prong on electrical plug to manifold tube on gas valve.

3) Also if a fluorescent light fixture is on the same breaker, that can cause burner to short cycle.

4) Connect water heater to different outlet and see if problem continues.

5) AO SmIth has service manuals for the FPSH series that download to your computer:

I have a whirlpool water heater mod. Fg1f4034t3nv. Igniter will not work'.instructions missing. Have all lines. Etc disconected how do I get assembly out?


I don't know because I can't see it, and I don't have manual.
But I can give you resources:
Call Whirlpool:
(877) 817-6750

Whirlpool is usually Craftmaster which is American which is AO Smith.
http://www.hotwater.com/water-heaters/residential/conventional/gas/
Age of water heater shows on serial number: first two digits should be year, second two digits should be week.

The market is always changing.
Find manufacturer using label on side of tank, find manual with parts diagram, and order burner parts. Whirlppol site does not have manuals.
http://waterheatertimer.org/Water-heater-manufacturers.html

It might be cheaper to install a new water heater yourself from box store for $330.00
http://waterheatertimer.org/How-to-install-gas-water-heater.html

Absolutely feel obligated to upvote the help.
Or take advantage of fixya expert assistance live.
For a price, expert works with you while you work on water heater or any do-it-yourself project.
Fixya is always less expensive than a service call.

A very old rheem fury water heater i assume it's just worn out but because of a space problem i can't go wider than the 15 inch diameter it has.


16" diameter water heaters could work if you cut away the metal and insulation off of 1 side of the water heater. The actual tank inside the shell is smaller than outside diameter.

American gas water heaters shows a 30gal 16"
model BFG61-30T30-3NOV
http://www.americanwaterheater.com/products/pdf/NRGSS00107.pdf


AO Smith has 16" Promax 30 gallon gas
Model GCV30
http://www.hotwater.com/lit/spec/res_gas/ARGSS01406.pdf

ELECTRIC 6 gallon point of use
http://www.hotwater.com/lit/spec/res_elec/AOSRE50400.pdf

You can get a tankless water heater if you have the additional money and a water filtration and softener system and don't mind expensive repairs if you install it yourself.
