I had tech check pressure with Navien on the phone . No problems found . My tech asked question about start up problem and Navien techs change the subject . I have a new issue which should be fixed with a flush . The original problem is worse than ever . New flame rod made no difference . I...

Last year it was constant short cycling for a couple of months . Then power off for 10 min. . No other changes or adjustment . Power up and the problem was gone for months . That sounds like processor issue to me . This year , it has a new dedicated ac outlet . No service or adjustment done to...

I will use a timer you would use to turn house lights on off . It will be be programmed off 10 min . for every 3 hours 24/7 . A thermostat connected in parallel will hold power on always if boiler room is above 55F. Power will only shut down for 10 min. if room is abnormally cold as a backup...

Do not know if corruption is the real cause.

Here is my update of the problem which is still happening . Flame sensor was cleaned twice last year . In December I called Navien . They said flame rod shound have been cleaned with newspaper or a dollar bill . They sent me a new flame rod for me to put in . I waited a week for a warm day to...

Thank You for your reply Jeff I cleaned flame rod . Worked for short time . Problem came back . Found original installer who moved to another town and used him for annual service check . He cleaned flame rod and said house wiring might be problem . He said he contacted Navien and they refused...

Cleaned the flame rod today . Dramatic difference . Still a few short cycle starts but often fires up without stopping . Makes sense that shut down for rainy summer allowed some oxidation . It had a bit of rust which I gently cleaned with 400 emery paper . It can be seen thru the combustion...

Thanks again for your input . Problem was gone for about a week and now it is back . I think I will clean sensor , Monday I will call factory if problem does not clear . They may know who can fix in my area and they may know about problem .

My Navien CH180 ( propane ) combination water heater boiler cycles burner about 2 seconds on and 2 seconds off and repeats on / off 7 - 9 times before it locks on for a long burn cycle . I also had Error 12 - flame out a few times . Error reset by unplugging power and reconnect . Manual says...

No , I do not do any programming . I use it for downloading movies . Also use spread sheets for work . It can open and edit excel sheets . Word processor can open and save same formats as microsoft . Good for surfing web . Lots of free software . Think I might look at astronomy .

Check out Linux Ubuntu OS .It is safe and free . Do yourself a favor and say good by to windows. I use v10 in one old netbook with 8 gig hard drive and trying v11 in my new netbook .

Install Linux Ubuntu operating system . It is free download , easy to install and virus proof . It can be installed beside windows so you can still hook up to devices like scanners that are difficult to install in Linux .
