Girard Tankless Water Heater III - Error E7
Hey folks. TLDR: Getting an E7 error code on our tankless water heater, except sometimes it's an E1 code and sometimes it's an E2 code. What's the problem and how do we fix it? We've been using our water heater with no problem as full-timers for almost 4 years. Finally, we moved out of the trailer and winterized it for the first time. We used an air compressor to blow it out as recommended and left for a few months. Now we're back in the trailer for a month and suddenly, for the first time, it's not working. We got the water hooked up and ran everything through the lines but when we switched on the water heater, it threw us E7. We tried turning it off and back on again, cleared the propane lines by running the stove and the furnace, and everything else is working great. The water heater kept throwing E7, except a few times that it would start working and get hot, and then suddenly throw an E7 again. Sometimes it throws an E1 or E2 instead of an E7, but it seems random. We've been testing it periodically by turning on the hot water and getting these different codes every time. Obviously, something is going on with the propane connection or flow that is preventing or stalling ignition, but since the error codes are vague, I don't know how to fix it, aside from ordering a new part (some kind of valve?) and taking it all apart, which I really don't want to do. Has anyone else had a similar problem? Any troubleshooting or fix suggestions? Thanks in advance.
12 volt does'nt work
i have a 2022 Forest River Flagstaff 21FBRS travel trailer. In 4 years we never had an issue until now. On our last trip, our 12 volt system stopped working (fridge, slide outs, lights, etc.). I made sure that the the battery disconnect switch was on. I checked circuit breakers. All okay. Once we got to our destination and plugged into shore power, everything worked. When we got back home I had the batteries checked. They were bad, so I bought new batteries. Still no 12 volt working. So I assume the problem is somewhere between the batteries and the the inside of the trailer. By the way, I tried the electric jack using only battery power and it works just fine. But I guess that is because it is directly connected to the batteries. Any suggestions on trouble shooting before I take it back to the dealer (which charges $165 per hour).
