Hi All, we decided to try dry camping and found ourselves without any hot water or heating. We have a Hydro-Hot HHE-500-07M. This morning I turned on the diesel switch and no hot water or heat? Went outside to look at the exhaust pipe and found raw diesel being pumped out of the pipe. The pump comes on but the diesel is not being ignited. All fuses are good, breakers good, diagnostic lights all green, but no fire? We are heating water on the range for the rest of the holidays and taking sponge baths. Can anyone shed some light on this?
