I have an Ultra High Efficiency Phoenix model PH130-80 gas-fired water heater from Heat Transfer Products. It was installed in August 2007 and has been working well...until today. I discovered that it was not operating and displayed an error code "F09" (no flame detected). I reset the unit and it attempted to re-light three times (as it's supposed to) but it failed each time, re-displaying the error code.
The remedy proposed by the manual says that if there's a spark and a flame (there is, but the flame extinguishes when the fan kicks on), to check the flame sensor. I have no idea what that is or how to check it. It also suggests to check for any flue blockage or condensate blocks. I disconnected the condensate pipe and blew water through it with a garden hose...perfectly clear. There doesn't appear to be any noticeable blockage in the flue openings and no sag in the pipes that would suggest condensation has blocked the flue. There's also no weather condition (e.g., wind, rain) that would account for a flue pressure differential problem. It's been over 100 degrees here but that's hardly unprecedented and I'm not sure whether that would have any effect.
I have six house guests arriving tomorrow and wonder whether there's anything I can do to get this fixed before they arrive or whether I just have to wait until I can set up an appointment with my installer (his office is closed on weekends). Cold showers make for REALLY poor hospitality!
Thanks for any suggestions you can offer!
