enjoyed this video. have the same problem. have to reset in order to get hot water. is that an indication that the ignitor is going bad? thank you

@@jeremiahlawson2725 that's quite possible, but you should first check the air filter, make sure its not clogged, and make sure the exhaust fan is turning on when the heater is on, if all that checks out, then I would check the ignitor..

@Renee Powers, you're quite welcome, sometimes its just something really simple, but its just about knowing what to check..

they're pretty efficient and space saving, you just need to lean some basic maintenance to keep it functioning properly.

much appreciated bro..

You're quite welcome Greg, and also much thanks for the Super Thanks..

That was a easy fix Julio, you're welcome..

Nuff big ups Flowers.

@peterhawth, there is a reset procedure, but the unit needs to be on in order to perform it, it sounds as though you have a power supply issue, a bad or shorted connection, a tripped breaker or worst case a burnt out pc board, try confirming the power supply first, it no issue there I suggest contacting Navien customer service, you can usually get a tech to walk you through a few trouble shooting steps, and possibly send you out a replacement part depending on the year of your unit...good luck with that..

@KluxBuster, it wouldn't hurt to try, explain to them what happened, depending on the age of your system, they may cover it. if not then you can always take care of it yourself..

Hey Angel, it is not supposed to burn out within a year, but anything is possible, somme parts have defects and therefore don't last as long as some others do, best to check it and make sure it is good, at least to confirm if that's the issue or not, good luck with that...

I had it off last night went to turn it on and it turned on but the code now says 046E which is the the High Limit Switch. I ordered it waiting to come in on Thursday to install it myself. Hopefully that makes the system work fine again🙏🏽 Thanks for getting back!

@@ANGELCRUZ-fe2yh you're welcome, hope that takes care of your issue..

To answer your question no, these units have what's called a flow sensor that detects when the hot water tap is turned on and thus kicks the unit on. The only other reasons I can think of that would cause this could be, a leak some somewhere in your hot water line or faucet , which would be most likely noticeable, a faulty flow sensor, or if your unit is connected to your home heating system, which is possible depending on the type or set up you have.

@@thediyyardie7192 thank you very much!

@@mattbingenyou're welcome.

@@mattbingen were you able to figure out what is causing the issue with your water heater?

youve probably got the problem figured out already, but it can be normal for your heater to run intermittently if its been set up for any kind of recirculation. the heater will take a temperature sample about every 30 minutes ( time setting can be changed) and if it senses a drop in the hot water outlet temperature it will kick on trying to reheat the water already in your hot water lines.

Thanks much for the compliments on my video, not sure how old the model you're referring to is, or if it has that capability, but to get to that info I use the mode button to find code history, arrow down to code history and select, once selected it should show date and time of error code..Hope this helps..

@@thediyyardie7192 its a few years old only. I can display the error codes but i dont see a way to display the date of last error. Thanks for replying

@@Honeyman76 depending on what model unit you have, the screen will turn red when an error code is tripped. at that point selecting error code history will show date and time.. other than that I would suggest trying Navien customer service, let them know what you're trying to do, a tech can usually walk you through it.. good luck with that, and you're welcome..

@@thediyyardie7192 it turns out after I spoke to Navien, the best they offer on the older Navs is 1 to 9 on error history. There is a second number which is hours, but the Nav Technician advised me that it is not accurate. I am dealing with a troubled client and the date and time given by the newer navs would have been helpful to see if stories are being made up about what is actually happening with the Nav.

@@Honeyman76 were you able to determine any idea of a date and time with the info you got from the Navien tech? even though he said it may not be accurate...

most likely a bad thermistor Rigoberto..

Are you saying the ignitor accumulated heavy soot after a day? if yes, make sure the ventilation system is operating properly, check filter to make sure its not clogged, you should also make sure the vent fan runs whenever the flame is on, sounds as though its getting more gas than air.. possible gas regulator issue also..

Hey Robert, yes you do need a regulator in the line, I would suggest get this done to the recommended code specs of the area you live though, unless this is for a RV or cabin, but yes you will still need to use a regulator in any case..

Bless up Nick, what type of maintenance have been done on the unit in the past, for example cleaning/descaling?

I did descaling every 2 years and cleaning every year.

@@ncurtis14 ok sounds good, make sure the temperature on the unit is at the recommended setting, it may have been turned down accidentally.. it could also be an issue with the flow pump, check to make sure that it is operating properly, but the best check to perform would be to use a thermometer, a digital type would work best, you need to check the temperature in three places, with the heat on, at the supply pipe from water heater to radiators, at inlet pipe on radiators, and at the outlet pipes, if temperature is 65 degrees going into radiator, it should about 55 out or a little less coming out. this can also help you to determine where temp loss/blocage issue is located.. keep in touch, let me know what you find..

Where is the flow pump? I am going to get a thermometer and do the tests. Also I noticed that the boiler runs louder when using the domestic water and quiet when the heat is on. Thanks again for your help.

@@ncurtis14 there are actually two pumps in the system, one built inside the unit called the prime pump, and the main pump on the outlet pipe leading to the radiators, the correct name is the curculator pump.. also visually inspect PC board for any sign of burn, a bad board will also prevent the unit from reaching the proper operating temperature.. and you're you're welcome Sah..

Hey Frankie, have you checked your intake air filter to make sure its clear of any blockages, and also what happens when you turn on the hot water, does the burner in the unit fire up any at all? you can look trough the sight glass while having someone turn on a hot water pipe, if it fires up and cuts right back off, it could be a issue with the gas supply to the unit, a faulty ignition module, blocked exhaust vent, or a number of other issues. try contacting Navien customer service if none of these seem to be the issue, they will actually walk you trough the trouble shooting process.. good luck, keep in touch, let me know how it goes...

there are a number of things that can cause that issue, you already eliminated two, others include restricted air intake\filter, you should also listen to make sure ventilation fan kicks on during operation, or some other restriction to the ventilation, or an issue with gas pressure or regulator.

@@thediyyardie7192I lost hot water out of no where, with a 003 error

Hey there Keefyboy, that info is in the video at the end, I show the box it came in, it says code number, if you google it, several sites will pop up, I ordered it through amazon, but its up you were you want to get it from.

@@thediyyardie7192 I don’t see a gasket included with the one on Amazon. I assume that also should be changed as well?

@@keefyboy4601 The on I got came with a new gasket, and yes it should be changed.

hey Hector, can you give me some more info, have you performed any work on the unit, did you check the sight glass to verify if the igniter glows at start up, and is it trowing any trouble codes?

@@thediyyardie7192 i didn’t see. It the only thing no code on the screen and for the shower and Faucet I have hot water

@@SuperCastroh ok, I misunderstood what you were saying, what radiator are you saying is not getting heated?

6 to 7 yrs at the time of the video.

@@thediyyardie7192 Thanks, looks like I have something to worry about in 5 years.

No biggy..

@Colton, possible a faulty ignition transformer or insufficient gas supply..
