I painted the floor & my hot water heater (Rheem PowerVent, 40 gal residental) vapor sensor is on lockout-safe mode & I can't figure out how to fix it?
The water heater is locked out. The following process should reset it.
1. Reapply power to the water heater and wait for 3 seconds for the system self-diagnostic check.
2. Within the first 30 seconds, the temperature dial must be rotated back and forth crossing the 120
degree mark at least six (6) times. This will reset the control and display a normal flash code
(slow blinking).
I looked up the water heater and I read the whole user manual for this system and it does not state how to reset the unit. It probably won't reset until the paint fully dries and it doesn't have any "vapor" left to sense. You can try unplugging the unit and leaving it unplugged for a few minutes and then plug it back in. This is unfortunatly a side effect of these "safe" units. I really hope this helps.
