Which LEDs are lit? how do you adjust the water temp on the gas valve, a dial or 2 arrows?
the leds that are lit are the "vacation" warm setting to the far left & 2 of the warmer ones. To adjust i turn the blower to the off position then turn it back on then hold the two arrows at the same time. without turning the blower off, it won't reset. then after a few minutes it just goes back to the 3 lit temps again.
I need to know specifically which of the "warmer" ones are lit
specifically, A & B
this error code indicates a flame failure
the heater has locked out due to a failed ignition attempt
that does seem correct because after I reset it sounds like the flame kicks in but then when the 3 lights come on it's just the blower that makes noise...I guess I need to call a plumber. What will he want to do?
You can try to reset it by unplugging it wait a minute then plug it back in
if the problem persists you will have to call a plumber
The plumber will have to do some trouble shooting to determine the cause of the failure
