Customer Question

Hi, I have a Rinnai RL94, just a few years old, 2 issues, mainly today was doing laundry on hot and I heard a beeping and found that the heater was flashing a red light and the temp was reading 12. Went back to normal after that but this evening it did it again and now doesn't go back to normal, any time I turn on the hot water it starts out ok but after 15 seconds or so it starts to beep and reads 12.
JA: How long has this been going on? And how severe is the problem?
Customer: This problem just started today. How severe? I have no hot water.
JA: Do you plan on doing the work yourself?
Customer: If possible, I'm very capable, carpenter, etc.
JA: Anything else we should know to help you best?
Customer: One other issue not as critical, while it use to work just fine it stopped letting me set the temp to 140. 130 is the highest it will go.

Error code 12 is a flame failure, meaning it fires and recognizes the flame then goes out

Has anything changed in the gas piping? Any new gas appliances or moving of piping?
