Got Hot Water? If your water heater is giving a error for Flammable Vapor Sensor then keep reading and watch this video! Fortunately this error code can be reset and hot water can be restored in less than one hour. The reset procedure will vary depending on which gas valve you have - I've listed all the popular models below.
Before attempting to reset the gas control, you must be certain to remove any substances that may have caused the FV sensor to activate and air out the area near the water heater thoroughly for at least one hour. The FV sensor must also be dry. Once you’ve determined there are no flammable vapors or liquids near the water heater, you may reset the gas control.
Flammable Vapor Lockout Error
1. If you cannot perform the work safely, then have a service technician replace this part.
2. Turn power to the water heater off. Thoroughly check the area near the water heater for any substances that may give off flammable vapors. If you find any flammable vapors or liquids near the water heater, remove them. Open doors and windows and air out the location for at least one hour. Once you are certain the area is clear of any flammable vapors or liquids and the sensor has been replaced, you may reset the gas control.
3. The FV sensor can also lock the gas control if it is exposed to certain non-flammable vapors such as ammonia, bleach, air fresheners, or other “smelly” chemicals. Remove any such substances located near the water heater. Open doors and windows to air out the location for at least one hour.
4. In rare cases, moisture in the air or direct contact with water can cause the gas control to lockout. If the FV sensor gets wet, you'll have to replace it. If your water heater has been flooded, do not attempt to reset the gas control. And contact phone number on the side of your water heater.
5. If you've gone through the FV Sensor reset procedure before but the sensor continues to activate, you'll need to have a service technician look at the water heater to determine the issue.
Honeywell Control Reset Procedure
1. Turn the gas control switch to off for at least two seconds
2. Turn the power switch back on and allow three seconds for the gas control to initialize and self-check.
3. In the next 30 seconds, Increase the temperature setting past the “HOT” mark, then back to “VAC.” Do this twice. Then return the dial to the preferred set point. "HOT" is recommended to reduce the risk of scalding.
4. Wait 10 seconds and see if the fault will clear. If the gas control is reset successfully and there are no flammable vapors near the water heater, the control will resume normal operation.
5. If the gas control fails to reset, air out the room again and repeat steps 1 - 3. If the gas control fails to reset after several attempts, call the manufacture or a licensed and qualified professional.
Intelli-vent Control Reset Procedure
1. Turn off power to the water heater and wait at least one minute.
2. Turn power to the water heater back on and immediately (within 10 seconds) press and hold both the HOTTER and COOLER buttons until the green VACATION LED light begins to flash.
3. Release the HOTTER and COOLER buttons and immediately press and hold the HOTTER and COOLER buttons again until the green VACATION LED light is steady (NOT FLASHING). When the green VACATION LED is steady, release both buttons.
4. If the gas control reset was successful, all LED lights on the gas control will light briefly then go out. At this point, the water heater should be working normally. No LEDs are lit when the water heater is working normally.
5. If the gas control fails to reset, air out the room again and repeat steps 1 - 4. If the gas control fails to reset after several attempts, call the manufacture or a licensed and qualified professional.
Robertshaw Gas Valve:
1. Turn the manual lever on the Control Gas Valve counter clockwise until it snaps to the "ON" position.
2. Keep the temperature dial on VACATION.
3. Plug in the power cord and turn on blower switch and wait 3 seconds for the system self-diagnostic check.
4. Within the first 30 seconds, the temperature dial must be rotated back and forth crossing the 120° F mark at least six times.
5. This will reset the Control Gas Valve and cause it to display a normal flash code for the LED on the left bottom of the Control Gas Valve. Note: Slow blinking is the normal flash code.
