What does sensor failure error code mean


http://waterheatertimer.org/How-to-fix-water-heater.html

Is this a heat pump water heater?
Or whirlpool energy smart?
Maybe the temperature sensor.

How to test flammable vapor sensor lockout on whirlpool gas water heatermodel nd50t122-403


You could clog up the screen on bottom of water heater... and this would cause FV system to trip because of overheated combustion chamber... then clean arrestor screen and push reset button located on front of combustion chamber to get water heater working. Of course you might have to replace parts to restore functionality.
Or pour some gasoline nearby and see if the water heater explodes, or if the FV trips. I would think this to be unwise.

New Reliance gas water heater won't stay lit


There is a sensor that shuts off the gas to the burner if a flame isn't detected within a few seconds. It will usually look like a tube that extends into flame of the burner. It may be defective or it may just need to be repositioned so more of it is directly in the flame.

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

Model # EE3Z80HD055V sensor failure?


1) Copy following link for troubleshoot resources including service manual, parts ordering, and general repair information:
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

2) 'Sensors' are temperature sensors located above each element, behind the foam insulation, behind the metal doors on side of unit.
Sensors feed temperature information to the computer chip that decides when to turn elements on-off.

3) Order parts direct from Whirlpool.

Water in basement in flood that covered the lower element. When power was turned back on, the green light on the top of the heater was blinking twice. When I hit the reset button, it is now blinking...


Yes sensor should be replaced along with lower element.

1) Manufacturer's say that flooded water heater should be replaced: Call homeowner's insurance company.
http://waterheatertimer.org/Flooded-water-heater.html

2) Brand of water heater is not known, but it could be the American or Craftmaster or Whirlpool energy-smart electric with control box.
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

3) With energy-smart:
1 flash is start-up failure, and 3 flashes is sensor failure.
The moisture probably shorted element and/or lower sensor.

4) The moisture inside tank will take long time to dry out, especially since the foam insulation is wrapped tight. To dry out element and sensor, you have to remove cover and insulation over element, but if you leave insulation off and run water heater, then the sensor is exposed to cool outside air and will not read temperature inside tank.
Plus a wet water heater is electric shock hazard.

If the water heater shuts off again unplug the white the sensor plug underneath the thermostat (The black plastic box). Then plug it back in. This sensor plug has a black and white wire going to it and it's possible the plug could have been loose going into the thermostat..

Whirlpool Energy Smart Water heater - light is solid green then every now and then blink a couple of times then go solid again.What does this mean?


2 flashes = high water temperature (the water heater comes set at 120, and you can set it lower or higher)
3 flashes = sensor failure (temperature sensor similar to a thermostat on regular water heater)
4 flashes = upper element
5 flashes = lower element
Links below are for Whirlpool manuals
http://www.whirlpoolwaterheaters.com/support/Manuals.aspx
http://waterheatertimer.org/pdf/Whirlpool-energy-smart-electric-manual.pdf

The water heater is working right now.
If the elements go out, they are available at any hardware store.
The temperature sensor is easily replaced and can be ordered from Whirlpool.
You might want an extra temperature sensor on-hand so repairs are not delayed.
Link below shows the product in detail.

Let the water heater do its job until it fails.

I have whirlpool gas water heater sg1j5040t3nov. It is blinking 6 times which says upper sensor failure. Is this something we can fix. Please advise.


Called whirlpool and explained the problem. They said I need to replace that upper sensor and so they sent me a part in the mail which cost roughly $25. (usd) not including the overnight shipping which is around another $25 or so. This picture is what I received in the mail. Comes with directions of installment. _273.jpg
