Rheem next day shipped me a new Honeywell control valve. About this product. Feeling clean & grateful for hot water! This changes to red flash code when there is an abnormal condition. w~{c=?Y=R}N',8+*Skw:,q7o{v%NnxpwQNZy ZpRe"n:o [KA8tX#aW:Y{HbTna+]U. I have not found a procedure to un-fault a Honeywell Electronic gas controller on any web site, so I think I am the only one to do this. I was told that you can use the yellow teflon and sealant for gas and water, but the water products do not work on gas. Take the front cover off. Well, I am having issues again and think I may have just screwed myself. Move the control to Hot and the Water Heater main burner should come on. Does the brains look at the voltage from thermopile to check for over heating or underheating? TOUGH! CS8840 pilot assemblies are designed for use with this control. So while they said just use the sealant through out, I actually used a combination of both. They said it needs to be assessed by a factory authorized repairman. Normally, you just need to dump a gallon or two at the most to get the sentiment out of the bottom of the tank. Repeat these steps with the new gas valve. Let me reiterate the steps Charles and I did so it will be on the end of the thread and readily visible. He gave me the $30 overnight speech but I opted for the $10 and some change shippingGot it 2 days later! Thanks guys!!! F-ING A BRA! Regardless what I tried, it was still 4 flashes. I also examined the circuit board and noticed a few minor differences, but I think the real problem was in the design and components. I have a water heater that is 18 months old and Im already repairing it? It is likely a Super Cap of 1 farad or more used for short term memory retention. Hope this information helps! There is no pilot, it just ignites completely as needed with electronic ignitor. 2. Not much of a DIYer am i but after reading about this scam Honeywell has going on about these modules i had to try this and besides how many more cold showers can one man take..My results? It works! Water heater runs both water AND heating in the home 0 degrees in Denver right now! Most others had it for from $200.00. NOTE: Only do this if youre sure that the problem that caused the overheating has been corrected. These things foul the sensor causing the 4 blink death light pattern. Shipping to: 98837. Then I came down later when I felt the barely warm water. One small jumper wire is all thats needed! I followed your instructions to clear the fault and they worked fine. As a side note, the light on the new valve is white. Could someone make a diagram or snap a pic and circle what posts to jumper? When the pilot is lit, it will only glow blue, and not look this intense. I would like to add my experience with this hoping it may shed some light. This one broke after less that 1 year. Reviews are especially welcome. If the new valve is basically the same model as the old one, you dont need to pay a plumber to replace the evil valve. When I relit the heater, it started up just fine and went into the normal 1-flash mode and still is, a day later. 5.0 out of 5 stars. Well, tried this with TWO circuit boards (one was original w/red LED, the second was replacement w/white LED). I suspect it is modified by Honeywell to be less sensitive to the issue because of complaints. Went back to buy a new thermostat. It will stay on once i jump the top left and right pins but it wont clear the code. I got right on the phone to service again and the first person said they would send out another Gas Control Valve, this time no charge for the shipping. Then This year the pilot went out and I tried to re-light by pressing the red knob pointed at PILOT and pressing the square igniter button. Now, I urge CAUTION when performing this fix as, without a working pilot, you could accumulate an appreciable amount of gas and risk an explosion. Pilot light will come on but wont stay on after releasing the button. The Right top Pin is the main gas valve. After spending 51 minutes with Sears customer non-service the problem was resolved within 20 minutes following Davids instructions. This does require one special tool, pictured at left. Genius. burners are on. At least then Ill have a stockpile when the water heater is out of warranty. If you need to, stick the screwdriver in from below to lever them loose. Even though it did not appear excessively dirty or clogged there was some soot present on top of the screen and a small amount of dust under the burner (& one dead ladybug). Dead as a door knob. Im trying this tomorrow morning. and then it might come back on or not. Be sure you first fix the problem that caused the overheating usually you need to drain the tank (which is recommended as periodic maintenance anyway). It is obvious that they are making a killing on money selling this to just about every water heater brand out there. This should at least get you hot water and time to get another controller from like Amazon. This unit is a P.O.S.! I think the Board discharged and thus reset the memory allowing it to operate again. The government mandates all this crap that fails! Ill call for the replacement to have on hand and keep the instructions. HELP !! If this becomes a regular issue, I might solder a pigtail to each of the terminals and get a battery holder from Radio Shack with quick disconnect terminals. w.c.) maximum inlet pressure, Body Pattern: 90 degrees with 1/2 in. I am now one of the afflicted and would not like to have to go through this every 18 months. The main burner would go out without being up to temp (it may of been shutting off on the high limit ?) Flushing the tank briefly seems to be a pre-requisite for this fix, so do that first. It took right off and has been working fine. The manual, and Sears parts deptartment, told me I needed a new control valve at $150. F Im so mad I want to shoot the prick who cornered the market on Honeywells crap. At this point the flashing light went to the Heartbeat flash (call for heat), the exhaust flap opened and the ignitor lit the burner. Look at a site like http://hometips.me/Mar/How-to-test-and-replace-Honeywell-gas-control-valve.pdf on how to remove the Controller circuit board (one screw and 3 tabs) and black control knob ( lean it to the side and it will pop out. Lessons learned eh? When I contacted Rheem again, without hesitation they said they were Fed-Exing me a new valve. Few minutes later, gave me the all clearThermostat requiring heat (No faults). I am trying to get an idea of how reliable the soluton is. I havent opened the valve yet out of curiosity but from what I read here, the Capacitor sounds like a good culprit. BONUS!!! The WT8840 water heater control from Resideo is designed for use in standing pilot applications using an immersion well for water temperature sensing. Say, Im going to rip you open, you dirty so-and-so. See whether the light goes back to its regular one-blink mode in response to this threat. The next two times we dealt with it in in a very non-technical way. This whole thread is very interesting. Use a flat tip screwdriver and remove the housing by putting the blade into the two top tabs and depressing slightly. Also, is the setpoint continuously variable as the dial is turned, or are the labeled settings stepped and all there are? Then once it started running went to one blink. Im not certain it works in all cases, but if it does, youre all set to go. They have a manual shut off. Remember these guys deal with this everyday. I would like to get my hands on the jerk that designed that piece of sh___. My hat is off to all of you. detail describe please. I had to be transferred to water heater division and wait on hold a while but it was well worth it.). Lore leaf, Great post! If it has now cleared. Resetting the #$%@!!

No flashing lights, no pilot light, nothing. ; 4. The valve location is high enough on the tank that sediment likely wont interfere with its temperature sensing ability; 2. After just a couple of minutes the code changed to 1 and now I have hot water. YOU are a SUPER GENIUS! my water heater pilot light went out. thank you so much. Honeywell Wv8840B1158 Manual.

CORRECTING LAST SENTENCE: main valve (Right pin to (+), So I would recommend to you ( with Valve off the water heater and no gas applied, to test the pilot valve (left pin to (+))with the AA battery, and test the main valve (Right pin to (+)), and each individually should click, photo of pilot valve solenoid This is an excellent solution. The cover is still attached to the back of the unit by a colorful ribbon of wires, with a plug at the end that connects to the circuit board.
