One more quick thing about code to out that I forgot a couple years ago we had somewhere around 30 inches of snow here in central Virginia up north of us in Washington DC and Maryland three for fetus nut and we have a lot of code twelves there because the vents were blocked they came out of the sidewall below the snow the unit’s couldn’t breathe so that’s another thing that can cause code 12 as a block then if you’ve had some kind of crazy weather event and all of a sudden you have a problem with your water heater it’s a big clue something weather-related has caused your problem pretty easy to fix if you do have something like that if snow is blocking your vent please be careful don’t break the vent when you’re digging it out use your shovel around it use your hands next to it don’t break the mint okay to clear the bed all right next thing I want to talk about is code 61 that is typically a fam code if you have a code 61 and would look that up it would say combustion fan failure the fan most likely has not failed although that’s possible what’s more common is it has got stink bugs in it wash a lizard a snake some kind of critter has gotten up in there mice maybe the house is sat for a while mice have found their way up into the vent built a nest in the fan all these things have happened 61 error code is somebody’s gonna have to remove that fan clean it out and inspect it and if something’s in it clean it put it back together.
If something’s not in it then you may need a part you may need a fan but code 61 is a combustion fan there and most often it is sucked full of something some farm but there are little critters and you need to clean it out and put it back together again these are things that should be done by saying with me authorized service provider next code the next code I want to talk to you about is the LC error code this is Rinnai specific I don’t know if anyone else who has an LC error code some manufacturers will tell you you should have these machines flushed annually I disagree if you have a run-on you don’t need to flush it annually it will tell you when it needs flushing it has an LC error code the way that works is the computer is paying attention to how long it takes for the machine to cool off after each cycle and if it takes too long to cool off three times in a row it pops an LC error code shuts the heater down you have no hot water you have to go turn the unit off and back on again and will restart and you’ll see the LC error code beep in and blinking that’s your clue to have the water heater service your technician can come out and do a flush on it remove the hardness clean a few components inside and have you good as new in about an hour’s time no big deal other units other manufacturers.
If you want to if you know you have hard water maybe every couple of years not that big a deal if you have super hard water you should be treating it anyway you should not be feeding mud alive and stunned through these heaters or a tank heater either for that matter it will ruin everything so the LC error code is something you need to deal with if you ignore it if you boot that heater three times on the third time it’s a hard lockout you will have no hot water until you have it serviced so do not ignore that problem if it is a commercial installation a restaurant and you’re getting the LC error codes restaurants run much higher temperatures and homes do the higher the temperature you run the faster the heater can scale up saying well the tank water heater the difference is a tank water heater wears out in a year or two you throw in the trash with one of these if you have hot water and a restaurant or other commercial application running at high temperatures then yes absolutely put it on an annual maintenance schedule flush it once a year maybe more if you have awfully hard water and super high temperatures just depends on the operation and your our conditions these are questions that your authorized service provider can help you with so that’s the LC error code specific to the renowned brands the next code.
I want to talk to you about is the code 14 the code 14 with most of these manufacturers is a part refers to a part called a fusible link it melts at a given temperature if you have a code 14 you’re finished you have a major problem with that water heater it is not coming back on you can push all the buttons in the world you can unplug it plug it back in whatever you want to do promise it’s not going to run something major has happened and you need to call you authorized service provider the code 14 means that a piece has in high temperatures and melted open the circuit has melted open you have to have the water heater service and something else is going on in code 14 as a symptom it’s not the problem so if you have a code 14 you need to have your tech determine what in the world happened that caused that code 14 so again this is not a common problem but I wanted to put this out there if you do see a code 14 don’t hire a flunkey go to your manufacturers website regardless of brand and hire a local trained insured licensed authorized service provider and have them fix your water heater all right now we’re going to talk about a couple of problems that are very very common but not a problem with the water heater it’s a problem in your house the first thing .
I want to talk to you about is the filter if you refer back to the first video if you have a flow problem the first thing you should be doing is cleaning the filter not going to redo that go watch the other video don’t want to take up the time here the second thing I want to talk to you about is a cross connection maybe you had something done in the home some new plumbing works something installed and a plumber crossed the water lines hooked up the hot to the cold and cold and hot that creates a cross connection and it can cause weird problems with the water heater now any plumber that says he’s never crossed the water line or never had a leak it’s either his first day or he’s not telling you the truth been doing this for a very long time all plumbers have had these problems everyone makes mistakes if you’ve had a recent plumbing project completed and now you’re having trouble with your water here that’s where you need to look first okay so cross connections are really quite common another thing that will happen is a low-flow washing machine if you leave them set on warm sometimes the solenoid valves are half open on each side and that allows a cross connection right there another very very common cross connection is a mop sink a laundry tray something like that where someone screws a Y connector or a hose connector onto it and they run it out to the hose to wash the car something or anything but they turn off the valve at the hose or leave the valves on at the faucets.
