Hi guys, Roger Wakefield here today.
It's 100 degrees in Texas so we decided what a great time to get up in the attic to work
on a tankless water heater.
So what we've got, we've got to Rinnai R-85 has a snar 12 error code.
We've checked the gas, we've checked the ground, everything's fine so we know that we're having
problems with our air.
So what we're going to we're going to open up and clean out the inside of it.
We've got the power turned off what we're going to try to do.
We're going to get in her here and get our blower motor out, that way we can get the
insides of it cleaned out.
So we removed the two screws to loosen the blower motor housing up top.
There is a clamp over here on the side.
What we'll do is loosen it to take off the rubber boot.
We'll go ahead and unplug this to get it out of the way.
Remember white to the left, black to the right.
That Kind of opens it up, and get this out.
Slide it out around everything in there.
Now what we're going to do is open it up so we can see how bad the inside of it is.
Now when you look inside here you can see parts of bugs, you can see dust, you can see
lent, you can see all kinds of things inside here.
This blower motor, as you can see is full of all kinds things.
That throws it off, and that also helps him blow these parts up into the burner assembly.
You can see, we've got the squirrel cage where it's good and clean now.
It's spinning and real smooth.
It's not offset, it's not bouncing it's not doing anything like that.
So now we're going to start putting it back together.
Guys, we're going to open up the burner assembly to try to get inside of it to see what all
we clean up on the inside of it in there.
As you can see inside we've got parts of bugs in here too.
So what we're going to do, we're going to clean this up and then start putting this
thing back together.
Always make sure you get the right screws back in the right spot.
The silver screws came out of the housing.
We want to make sure that we get those up there and the brass screws in where they go.
You've got two wires, one that connects on each side.
Make sure you get those back into your screws also.
Remember this clip there's a slot for it right up inside that that slides into.
You're going to slide that into the position, get it up, set your two screws here and then
we'll start putting it back together.
Here's the clamp the holds the rubber boot on.
Make sure you turn around get it in front where you can get your fingers on both sides
when you get that boot in position and you can clamp this on there so it won't ever come
off.
So guys as you can see we're wwrapping up in the car.
It got a little hot in there, as a matter of fact, it got real hot in there.
Cleaning out that Rinnai R-85 that did not clear the error code 12.
As you can see on the exhaust fitting, there was a crack on the PVC.
We've talked to Rinnai.
So now we're trying to figure out if just changing that piece willl make that work.
We've also got the serial number model number of that unit and we can find out exactly how
old it is.
It Maybe replace that.
