FVI12 E3 Tech Support Updated March 08, 2017 17:53 Follow John Smith Thanks. I have received the ignition pack, installed it and the unit worked perfectly with no errors at all. I appreciate your prompt assistance with my issue and I will let you know if something happens but for now, I am pleased with your customer service. I ran it for 2 days now and no failures so far. thank you so much for all your help! John =) Tech Support Hello John Smith, Good day! We apologize for the inconvenience. Upon analyzing the issue, this has something to do with your ignition pack. We can send you the part. We just need a copy of your receipt or any type of proof of purchase with order number and date of purchase visible for warranty validation. You can just send a copy here along with your response. Thank you! Regards, Technical Support Team Eccotemp Systems LLC 1.866.356.1992 www.eccotemp.com John Smith Ok, took off the vent as you suggested. It did not change anything. I put a T into the gas line right before the water heater and put a gauge on it. When static it will read 11" water column, and when the heater runs it drops to about 6". I then shut off the gas valve and T'd into the line a second time to hook up the water heater to a small, independent propane tank with its own regulator. This gave me 16" water column when static and 11" water column when the water heater is trying to run. I switched the line and regulator with a different one and again got 16" static, 11" running. The same issue and E3 code occurred in all scenarios, although sometimes it is able to run and stay lit for a few minutes, during which the gas pressure remains constant, showing no signs of dipping before being shut off. The moment the flame begins to die down coincides with the moment the fan shuts off. What would cause the fan to shut off 5-6 seconds before the flame and gas shut off? Then, when the gas valve is closed and flame killed, the fan kicks back on and runs for about 10 seconds. How should I proceed? Tech Support Hello John Smith, Good day! We apologize for the inconvenience. That is a possibility(flame sensor) however that is a very rare occurrence and that is 1 out of 50 as to say. It could also be the ignition pack since this is the part that sends signal to the flame sensor and igniter to function. To further diagnose, I would suggest to try to run the unit without the vent to ensure that the exhaust air is freely getting off of the unit (part of Troubleshooting). If you have done so, I would also suggest to try switching to a different gas hose and regulator. Bad regulator causes insufficient or excessive gas supply. Regards, Technical Support Team Eccotemp Systems LLC 1.866.356.1992 www.eccotemp.com John Smith What I suspect, based on the continued clicking attempts to ignite after it has already achieved ignition, is that it might be a bad flame sensor and was hoping you could weigh in on that. I'm guessing that perhaps if it's not sensing the fact that the flame is already lit, it will give up and throw an E3 code for insufficient gas flow. Can you confirm or deny this possibility? Thanks. Tech Support Hello John Smith, We sincerely apologize for the inconvenience. First, if you have been running your water heater at excessive temperatures then you may have permanently damaged your over temperature sensor. A good indicator of this is, when you attempt to operate your water heater, the fan comes on but you do not hear the ignition sequence (rapid clicking). If this is the case, contact technical support as you may need to purchase a new sensor. An E3 error code appears when there is a failure to ignite the burners, and this is usually the result of: 1. Insufficient gas supply 2. Excessive gas supply 3. Blockage of exhaust If this is a recent install, ensure your gas valve on your supply line is open and that there are no obstructions in the gas line. Contact a gas company to have your gas lines inspected and gas pressure measured. The gas pressure of Liquid Propane should be 8-10 inches of water column and the gas pressure of Natural Gas should be 4-6 inches of water column. If you have a gas tank, you could also have run out of gas or it could be extremely low. Your gas company should also verify that this is not the case. If your exhaust venting is blocked, exhaust can build up within the burner box and alter the fuel to oxygen ratio, smothering the flame. If this is a recent install, confirm all packing materials have been removed from the water heater and the vent pipes. For a water heater that has been working properly for a period and is now having issues, it is still necessary to check for blockages. Some common examples of blockages are bird nests, bee’s nests, or small animals. Confirm that nothing has bent or crimped the vent pipe as this may also prevent proper exhaust flow. If the igniters keeps on clicking, there are 2 possible reasons for this: Faulty flame sensor or ignition pack. Please the wire connections on the flame sensor and ignition pack. Make sure that all wires are connected properly. Please let us know after. We appreciate and value your business, Technical Support Team Eccotemp Systems LLC 1.866.356.1992 www.eccotemp.com John Smith Hi, I'm getting an E3 on a water heater (FVI12) that was installed last fall. Worked well for several months, but 2-3 weeks ago it started shutting off randomly, sometimes after a minute, sometimes after 10+ minutes. You could hear the flame go out and a few seconds later the fan would follow. Turning the water off and on would reignite it and allow it to run for another random period of time. As of yesterday I can't get it to stay lit at all. The fan and ignition sequence begin as usual, and the burner lights, but you can hear it continue to click as if it's still trying to ignite. The fan will go off soon after, causing the flame to begin to die. A few seconds after that, the flame is extinguished and the fan comes back on to pull fumes out. What's going on? Seems like maybe a sensor is broken? No exhaust blockage, and my gas stove on the same line is still receiving adequate gas. Thanks in advance.
