Power direct vent water heater blower will not shut off. Plenty of hot water. Gas water heater. 75 gallons. State select model pr6 75n rvt. The blower is integral to the unit. I could not find the exact model number on the web site and did not find the problem under the troubbl shooting guide. The blower runs continueously even after the gas valve is shut off. The water heater is a high efficiency condensing type.

I had a similar problem. The electronic diagnostic system said I needed to replace the gas valve - all the lights were lit on diagnostic system. With my model the diagnostic system gives only two solutions: 1. replace valve, as above 2. Turn electric power off to system. Neither of these worked and I was looking at calling the plumber "again" for this State water heater. I tried one more solution, as there is no directions in the manual for resetting the system. I unplugged the clips that attach to the electronic wiring on the bottom of the electronic diagnostic system and that reset the system. I don't understand why turning off the power at the breaker didn't reset the system but this worked!?

I have the same pr675nrvt model and experienced the exact same problem when I returned home from a week long absence. I followed the advice of tyggyr and the blower shut down almost immediately. I ran some hot water to test the system and the switch shut off the blower within a few seconds of the gas shutting down. In my case, it may simply be a result of the long absence - or - a warning of problems to come......thanks for the advice and picture.

Thanks for the photo tyggyr. It was really helpful. I have a 50 gallon version and the only noticeable difference is that the water temperature adjustment knob is black rather than red like in the photo above.

I also was able to get the relay to disengage by tapping on it. I tried using a piece of wood first but that did not work. A small hammer did the trick. Now, time to find a replacement relay...
