Question about General Electric GE SmartWater Household Water Filtration System - GNWH38F
I have no hot water, my gas is on, the setting is on hot help
First try turning the knob all the way to "pilot" then turn it all the way to its hottest setting.
It sounds like the thermostat/sensor is stuck. This may jar it into working again.
Also look for any leakage or water around the burner.
You will probably have to replace the gas valve in the near future.
Also try tapping the side of the gas valve.

Seems if it is a unitrol gas valve, then you may have problems replacing it since they are obsolete? MIne was in a flood and now they are trying to say I need a new water heater even though the place is going to be demolished in a year or so :(

If the pilot is lit and the water heater is cold then the thermostat [the dial that you have set to hot,the metal looking box,its also considered the gas valve]its up to it to do its job.if wont then the box/gas valve is bad.ps make sure the knob that you use to lite the pilot is in the on position.its the knob that you hold while liting the pilot then let go and turn to the run position.i hope you can get hot water soon. God bless,tom

SOURCE: lighting the pilot light
The steps involved can vary slightly depending on your furnace model and pilot valve type, so if possible try and find the instructions inside the furnace door cover or in the instruction manual.
This is for a gas fired furnace, but applies to any gas-fueled appliance including water heater.
Two of the most common types of pilot valve body assemblies either have a red reset button and a gas valve or no reset button and a valve knob that can be depressed. But whichever type you've got, if you have an older model furnace with a standing pilot (flame is lit all the time) then this is the basic procedure.
A natural gas flame should be a bright blue with the tip of the flame having just a tinge of yellow. A propane flame should have a bluish green flame with a tinge of yellow at the tip. The flame should be strong enough to hit the thermocouple tip about 1/2 inch from the tip end. If the flame is weak or shaky looking, check to see that a breeze or draft is not blowing on it. Adjusting the Flame
There is usually a small screw on the pilot valve body that will adjust the flame. You may have to refer to the manufacturer's instructions to find the screw. Turn the screw as needed to adjust the flame throw. Yellow Flame
A yellow flame is caused by lack of air and incomplete combustion. It can be caused by a dirty pilot tube tip. Split Flame
This is caused by dirt in the pilot tube. Take a needle or small nail and gently clean the tube. Flickering or Wavering Flame
A flame that flickers is usually caused by a draft.

Most likely it's time to replace the thermocouple, the safety device that makes sure the pilot is lit. New thermocouples are cheap and you can find them at most hardware stores and the big-box places (Home Depot, etc.)
Here is a site with basic information to get you going.

Your water heater most likely needs a new thermocouple. (the device the pilot light heats to develope power to operate the gas valve). They are not expensive and usually available at good home improvement/hardware stores.
Bring your old thermocouple or as much information about your heater to the store to ensure you get the correct replacement.

SOURCE: gas hot water tank, pilot light
Look inside the water heater when it is heating the water, the flame should be blue. If it has yellow tips on the flame, it needs an adjustment to the air shutter. There is a nut on this air shutter to make this adjustment. This adjusts the air gas mixture. You may first try just simply tapping on the burner lightly to loosen any debris that may have built up and vacuum it out. MAKE SURE YOU TURN OFF THE GAS BEFORE CLEANING THE BURNER!! Also, check for drafts that may be blowing out your pilot light, Furnace register or outside drafts on windy nights. Some water heaters have an automatic shut down if the water heater gets too hot, so don't have it set to its hottest setting. Most water heaters only last about 10 years or so, It could be you are ready for a new one....Joe
