Question about Heating & Cooling
Rinnai 403FT sounds like a fairly old heater (probably about 15 years old???).
There is no E:01 in the instruction manual but a E:07 which is overheating. Could it be this number instead? If so it could be caused by too much dust inside (or the fan not working anymore, if that's the case... sorry but good luck to find the part...)
With gas heaters, the other basic question you should ask yourself is "when was the last time I serviced my heater??". It is recommended to get them serviced every 1 or 2 years.
It consist in having a licensed gas fitter to open it and clean/test everything inside the heater (yes, like your car).
9 out of 10 problems with a gas heater are solved with a simple service, I would suggest you get a gas fitter to check it out!

You may be able to help me with my 403FT.
I have nothing coming up on my control panel no lights anywhere.
The power supply is all good so it has to be within the heater.
Can't see a fuse able link.

SOURCE: would like a manual for
The model number (403FT) has either been discontinued, changed or is incorrect. However, Model # RHE309FT closely matches the heater you described and has the timer and temperature features you are wanting to preset.
