![]() ![]() After talking with the phone tech support guy for 15-30 minutes he informed me that this style of burner is prone to it (and not used anymore anyways with rheem water heaters) because the gas has to make its way to the pilot flame which is a couple of inches away.Like any other household unit, a water heater is not deprived of malfunctions. The first pilot light ignition resulted in a giant fireball / delayed ignition so it looks like i'll be replacing this thing anyways. After disassembling and reassembling everything it worked, i'm starting to think that the shielding for the Piezo igniter switch wasn't on enough and it found a contact on something to ground to instead of setting off the ignitor. UPDATE#4: Got the pilot to light and hold a flame inside, still unsure what the cause of the initial hiccup was. Anyone have any advice? There's air going in because It's not air tight/sealed at all, I would think the pilot would light without problem this way. UPDATE #3: After confirming the pilot works outside of the combustion chamber, i put it back in loosely with just 4 screws and could not get it to light. While out, i found the FVIR, it looks intact. If it did, i'll have spent a week taking cold showers for no reason since the water heater will have to be replaced anyways haha (it's been a mildly amusing exercise taking cold showers) If not, it might point to the Guardian FVIR system at which point I'll have to call tech support to figure out how to find out definitively how to tell it got tripped. ![]() Putting it back in now after a quick water break/diet soda break to see if i can get the same to happen inside the chamber. if i waited half a second or more after pushing the pilot light, i couldn't get it to light regardless how many clicks i got with the igniter. the spark gets put out by the gas we have (whatever CA's natural gas is) so you need to catch the first hit of gas immediately with spark and this was outside of the burn chamber. with the pilot tube and igniter hooked up, was able to get the pilot flame going. UPDATE #1: ended up taking everything out again. I thought that surely 5 minutes was enough to purge any air out of the line and I was starting to get uneasy having an open gas line even though I couldn't smell anything and the pilot tube is tiny.Īfter the last attempt to light the pilot, I disconnected the pilot tube from the thermostat and with the gas on and the thermostat switch in the pilot position, i pushed the pilot button to see if I could smell gas at the thermostat and there was gas flowing through (could smell it easily).ĭoes anyone have any idea as to why the pilot light might not be starting or know if it could take more than 5 minutes of holding down the pilot button (with the dial on pilot mode) to purge all of the air in the 18" of tube? I turned the gas back on (in-line with the pipe) and with the dial on pilot mode on the thermostat, I pushed down and held down the switch in the pilot position for 5 minutes straight (timed) trying to ignite every 30 seconds giving the igniter a handful of clicks. At the time it was out, I confirmed that there is spark at the pilot end. I pulled the old pilot assembly out, mounted the new one in its place, put everything back in and tried to start the pilot light and nothing happened. (For reference and was not replaced) This is the style of thermostat/controller: I got Rheem to replace the entire igniter, pilot tube and here are the parts that i received from rheem: Didn't see any leaks like the old one that failed prior, decided to do some basic troubleshooting and figured out the components to try to fiddle with. Water heater went out last week and is 6 months outside of the 6 year manufacturer's warranty. ![]()
