SOURCE: gas water heater kenmore model pilot will not stay lite

I have the same problem. Water heater operates on a very simple principle. of thermo-mechanical feed-back and response. In my case, I have a Kenmore Power Miser 6, NG heater with an electronic pilot ignition system. The heater is just over one year old and last month (conveniently just after the 12 month service warranty expired) the pilot light started extinguishing on a very regular basis. I find it interesting that the very problem I am experiencing, is happening to other Kenmore owners (victims). The solution can be found in replacing one of two possible components; the pilot assembly or the gas valve manifold. The price of DIY pilot assembly replacement is approx. $60 . The valve component is significantly higher. Water heaters are designed and built to provide years of trouble-free reliable service. This is the first Kenmore product I have owned. From a customer perspective, with regard to product performance, Sears/Kenmore needs to take a strong look at their supplier quality. Oh, by the way, contacting Sears for remedial relief only managed to frustrate and infuriate me. You see, I am in Quality for a world-class aircraft company. I understand what ethical steps are required to satisfy a valued customer. I plan on ripping out the defective unit this weekend and replacing it with a reliable Home depot special. At least with HD, if the heater fails to perform , I can return it. Hey Sears in Chicago, don't come crying to the consumer when you are looking for the trendy "bail out".

SOURCE: Rheem 40 gallon gas hot water heater, pilot light

To make a short story long (I need to include all details, sry)…

I got up one morning and realized that we did not have hot water. I re-lit the pilot light and as soon as the burner went out from heating the water up, the pilot light would go out. After reading several posts regarding this issue, it seemed apparent that the thermo-coupler was the problem. Since I am a little bit handy around the house and very tight when it comes to opening my wallet, I bought the device from Lowe’s ($8.98) that was recommended by my online advisors and after a few googles, figured out how to change it. No help. The pilot light still goes out.

I gave up and went to Home Depot to purchase and schedule the installation of a new hot water heater.

STICKER SHOCK

A new Direct Vent type water heater costs around $800 with an additional $450 for “special” installation. Add a few fees to that and the grand total came to about $1450.

I felt like I had no choice since my wife and 2 daughters refused to live their life without hot water and I had no clue about how to fix the dam thing.

The plumber assigned to the installation stopped by to evaluate the site conditions and quickly noted to me that the 8 year old water heater tank was in good condition and that the gas controller was probably faulty, which could be purchased online from the manufacturer. I quickly cancelled the Home Depot order and purchased the controller for about $120 after shipping and tax. Immediately after the installation it seemed that the problem had been solved. A few days later the pilot light went out.

I called the plumber and explained the situation and he recommended that I purchase another controller because the one that was shipped to me was probably bad. I searched around town and found a plumbing supply company that had the correct model in stock. Two days later the pilot light was out. I cleaned up the controller and returned it to the store and asked the plumber to please schedule a visit to repair this dam thing.

When the plumber arrived, he hooked up a gauge in several locations and confirmed that the correct amount of gas (cfm) was being delivered to the controller, pilot light and burner. He then proceeded to remove the fire box to make sure that the igniter, thermo-coupler and pilot tip were set properly. He inspected the pilot light tip and said that he found the problem. Using about a 1/64” tip drill (can be purchased at a welding supply store), he cleaned the tiny hole that releases gas to the pilot light. I felt a sigh of relief because I was certain that the problem had been solved. $65 dollars (plumber’s fee for an hour of work) and 4 days later the pilot light went out.

I called the plumber and he said that the controller that I purchased online must be bad. Too embarrassed to return to the first plumbing supply store, I found another one in a different town that had the correct model in stock. Three days after changing the controller the pilot light went out. I returned the controller and a six pack later I decided to do some extensive googling.

The key term here is “DIRECT VENT”. This seems to be a very common problem with direct vent water heaters and I was about to find out the reason for this phenomenon. I read a post by an individual who wrote that if the vent becomes detached that the inflow of air can become contaminated and extinguish the pilot light. I decided that before I spent any more money on a plumber that I was going to take the vent apart and find out what makes it tick.

My direct vent system has 2 parts to the venting, an inner pipe (3” nominal diameter) that serves as the exhaust and the outer pipe (5” nominal diameter) that serves as the internal flow of air which supplies the pilot light and burner with oxygen. On the outside of the house a vent hood helps to segregate the two by extending the exhaust about 3” beyond the intake. I looked into the hood at the end of the pipes and discovered that the internal pipe which consisted of a 2 piece slip joint had come loose from the elbow that sets on top of the water heater. This slip joint pipe was not attached at any point with screws or clamps and was loosely setting over the elbow on one end and into the hood on the other end, allowing it to detach. Apparently, when atmospheric conditions were right, the burner idled down from heating up the water and extinguished the pilot light because the intake was saturated with CO2 from the connection failure.

I purchased a section of 3” pipe that was long enough to be installed in one piece. I connected it to the elbow using a stainless steel hose clamp. I had to disassemble the pipe 3 times to make adjustments to the length and position before I got it right, but I should not have any more problems with the pilot light.

The problem here is time. It takes a lot of time to get this right. When the plumbing contractors installed this unit during the construction of the house, there was no one around to make sure that they got it right. It is probably common to use a 2 piece slip joint type connection, but I feel like it should be attached with screws or clamps. In my opinion it is not rigid enough and can detach easily, especially if it is not installed properly. A one piece connection that is attached at one end with a hose clamp and then held in place at the other end by the hood is fool proof.

SOURCE: pilot light on water heater wont stay lit

The thermocouple has failed. It is the temp probe that goes from the pilot lite burner area to the control valve. Go to your local plumbng repair shop and buy one. Most appliance parts stores have them also. Take the old one with you and they will hook you up with an exact replacement. They are not that hard to change. Usually a nut or 2 screws in the temp bulb area at the burner end and a nut that threads into the control valve.
Make sure before you install the new one that the area where it mates to the gas valve is clean. Should be about a 20 min job including clean up with replacement parts in hand.

SOURCE: need to empty reliance 501 hot water heater how?

1) Shut the breaker off to it at the panel. 2) Hook a hose up to it (the bottom has a drain). 3) Close the valve to the water heater (on the cold water supply). 4) Open drain on the bottom of water heater. 5) Open the relief valve to allow air into the tank (it won't drain otherwise - think if you put your finger on one end of a straw - the liquid stays in until you let go). Why are you draining it by the way?

Reliance is made by AO Smith company, and air intake located on bottom of unit.
Make sure you have adequate incoming air and vent is working.
Remember, the pilot is located upwards from the viewing sight-glass, so it is sometimes difficult to see pilot.
Pilot flame must burn clear blue, with bits of yellow and red. Yellow flame means inadequate air supply or venting.

Reliant 501 Natural Gas won't stay lit


Reliance water heater?
Thermocouple is good if the pilot stays lit continuously.

501 is older model. Unknown if this unit has FVIR protection and sealed combustion chamber or open air intake on front of unit.
http://waterheatertimer.org/pdf/Reliance-2006-Service-Handbook.pdf

With FVIR protection:
Get more fresh air to the unit.
Clean the flame arrestor screen.
Test and replace the thermocouple:
http://waterheatertimer.org/How-to-test-water-heater-thermocouple.html
Inspect and clean burner and combustion parts
Test gas pressure, bleed air out of gas line.
Replace gas control valve.
Test draft air by lighting match and see if smoke is pulled into the vent pipe at draft hood on top of tank.

Reliance 606 Hot water Heating element (Pilot light) won't stay lit


Gas water heaters don't have elements, so I am confused about what type water heater you have..
Look on the side of tank for the label.
Find the brand, and type. Does it show BTUs? Or does it show wattage?
Then re-post question with this information, for best possible answer.
Also post question on Tank forum.

Reliance 606 natural gas water heater - model #640YORT - water does not stay hot. pilot has to be clicked to heat and then u can use hot water til tank empty and it will not continue to heat water.


If I understand correctly, the pilot light is not staying lit.
You light the pilot and water in the tank reaches temperature.
Once hot water is gone, then pilot light has to be lit again.

Gas pressure is good, and gas is flowing.
Thermostat is working at high end because it cuts off heating.
Vent is working because tank heats up.
Air intake is working.

Gas control thermostat might not be reading low temperature. Replace gas control valve.
Pilot tube might be dirty. Clean burner parts and combustion chamber, and air intake, and vent.
Backdraft might be blowing out pilot. Check for constant updraft by running water heater 5 minutes, and then light match under vent hood and see if smoke goes up.
Very hot air can put out pilot, especially when water heater located in attic. Add ventilation.
Improper vent might have water dripping back down into combustion chamber and putting out pilot light and rusting out the parts. Inspect for rusted parts and water.

I light the piuolot button and when i let go of the pilot button the pilot goes out does not light burner wont stay lit


When you light the pilot lite you have to hold the button down until it gets the element hot enough to stay lit. If you hold down the button and lite the pilot and let it go right away it will go out. What to do is hold down the button and lite the pilot and continue to hold the buttn down for about 45 seconds to a minute then let it up very slowly and you will see if it is going to go out by the flame getting smaller as you let up on the button. If it does start to get smaller conitnue to hold it again for a few seconds and repeat the process of letting it up slowly. when the control element gets to the right temperature it will stay lit then turn your valve to "ON" and the fire will start up and continue to heat the water.

The paid answerers might have a specialist in your model of water heater.
As a free answerer, I specialize in providing resources that might help you for free.
When you say the gas control pieces, I assume you mean you replaced your entire gas valve with a generic dial-type gas valve.
You replaced thermocouple, but you did not replace burner assembly that includes the pilot tube.
Your other gas appliances are working fine.
You have not installed a new gas furnace with a blower that is vented up the same chimney as the water heater.
You have put your hand near the vent hood to see if there is backflow coming into the water heater when the furnace turns on.
You have removed the vent hood to give you access to the vent pipe, and you lit a match and the smoke from that match drafted upwards. You have done the lighted-match test when the furnace turns on which reveals the general condition of the venting stack.
You have checked your outdoor vent stack to make sure there is no obstruction, or the vent hood is not missing.
The burner flame on the water heater is a clear blue color with very little yellow. This shows the quality of the combustion air and reveals if amount of gas flowing to burner is restricted.

They send a generic gas water heater manual with no troubleshooting

I don't think the 501 would have a FVIR flammable vapor prevention because it is older

Pilot won't stay lit in Reliance 606 gas water heater


The Reliance 606 has an enclosed thermal couple. Before you try taking that assembly apart take a wire brush to the bottom opening directly under the burner. There is a metal filter on the very bottom of the water heater. It could be that the filter has gotten filled with dust or animal hair. It took a serviceman 2 days to figure this out for me. The water heater has to have good airflow through that filter to work well.
