when the repair guy cleaned water heater did he run white vinger through the coil inside the heater. Does the control pad show any errors

mine did a similar thing, when in off position, it would only turn to pilot/ignite, but would not move past this point. I took off bottom cover to locate regulator. where the slector knob shaft meets the regulator, try spraying wd40 in the top of regulator where square shaft goes into reg. There is a saftey lock mech in there, and in my case it was stuck in the locked position. I then worked the knob back and fourth applying alot of pressure, but not enough to break the knob. it worked after a few tries, and lights and functions normally, locking again if pilot goes out. good luck.

I had the identical trouble with my Rinnai 431F just now & read the unanswered posts.
I checked my intake & exhaust & found them connected & intact then went out to check the exterior vent assembly. The "bell" or dome was almost entirely clogged with ice.
I suspect the 60 - 76 lights flashing means insufficient combustion air.
Anyway, I took a hair dryer to it & in 10 minutes it was working as well as ever.
This won't help you October posters but if anyone else has this problem in the future I would start with the outside vent assembly. Get a good look right up inside because I would have missed this ice if I didn't get up close with a flashlight.
Here's a good source for manuals too...
I'm going back to bed.

You could have something as simple as an air hose off, or a piece of carbon on the flame sensor. Your problem could also be a gas valve , which is much more complicated. If you are handy with tools you could be able fix either quickly. If you’re not good with tools you will need to get some help. Either way you have to have some back ground info on your heater. Get in touch with Rinnai and get a service manual for your unit. They cost around $15. If you have to call a service guy, use the Rinnai web site to find an authorized service person. Don’t just let your fingers do the walking and get some guy who has no idea what a Rinnai is. You’re only asking for trouble there. Your unit is a little older so don’t be surprised if parts are hard to find.
