I'd hate to have to replace it if I don't have to. I should think that it is extremely "low mileage" for its age, so I am surprised to see it having problems. The house is a weekend cabin and only sees 10-12 24-hour visits a year - so the unit gets very little use. Should I replace the flame rod? Isn't there some flow sensor that might cause this? I did so and am still seeing the same symptoms and the same error code. The plumber inspected all the Rinnai's electrical connections, cleaned the flame rod and burner and told me to clean the heat exchanger - by flushing it with vinegar for an hour and cleaning the filter. I'm sure it flows a lot more than the other appliances and this is why it fails. Other hot water appliances (kitchen sink, bathroom sinks, etc.) worked fine. When he arrived, I told him that the unit had been loosing flame every time you'd try to fill the bath after 5-10 minutes. Since I was overdue for a checkup on all my domestic plumbing, I contacted a local plumbing/Heating guy and asked him to come out and do a service on both the boiler and our R53 tankless water heater.
