Common Tankless Water Heater Problems & How to Fix Them

[@NugenDurong]

You saved my house from freezing up in -32F. The vent to my combi boiler was frozen shut. I cleared the ice and the flame was able to ignite and heat the water!❤

[@ecoelsol5784]

I didnt know that the higher the temperature the hotter the water and the lower the temperature setting the colder the water. Amazing!!!

[@timmartin5812]

what causes the pure pro tankless water heater to continue to accuate even without demand

[@Vd29280]

Thanks for the video! I have a problem on my rinnai condensing water heater. I flushed it today and after doing it, even when heater is not running, there is a steady flow of water from condensing pipe. What to do to fix it. Thanks!

Kitchen and bathroom sinks are fine for the most part. Shower is inconsistent. When water does reach close to set temp, the temp is not maintained and short-lived. Could it be that the capacity is not high enough for the shower fixture which is a rainfall with handheld and regular facet - only one outlet at once?

[@mattdale81861]

I have the same problem. I think what he's suggesting is a bigger reserve tank or new circulation pump?

[@mygt8a4re]

So you may need a tank for your tankless system to operate properly? Great engineering there! 👍

[@reecedresen9746]

Oh it gets better the lighter on stops working and the wind blows out the pilot light all the time doese not take alot of wind

[@chicinthewoods]

Great video... HELP! Ours are brand new but wont ignite...why??? HELP!!

[@GoPaschal]

Ensure gas supply is hooked up, turned on, and your gas bill is paid up. If all of those are done I would call your local plumber!

[@carloslozada470]

Bumper tank ? How much is that

[@jefferyjohnson6240]

new home purchase first time dealing with tankless. I have a westing house tankless with p-920c i have really good water pressure but the system demands a lot of water to kick on the burner I have to run another faucet to get hot water iv already cleaned all filters and screens and every time its done running I get err 16 and 72 anything helps thanks

[@GoPaschal]

ERR 16 & 72 relate to over temp. warning & Flame Sensing Device Fault. There could be a few causes, but a plumber would need to be physically in front of the unit to diagnose. I would recommend calling your local plumber for an accurate diagnostic.

[@Tyler-ec8hv]

Did u find out the problem???

[@rubycoravillon2006]

Pls tell how to do the adjustment

[@Biscaynedave]

Great Vid thanks, I have a Navien tankless--so i turned off the water main to replace a shower valve, the water was off for 2 hours approx, now the water is not getting hot and no error codes, did i mess it up !

[@RyanVu-k7v]

Hi! Need your expert advice. Whenever hot water in the shower is turned on, the water flow/pressure goes weak then strong, weak then strong… also the tankless water heater makes pounding noise on the hot water line. Do you know what is going on there and any advice on how I can fix it? TIA

[@chrislamountain4311]

How do I talk to a technician, I got issues

[@RyanVu-k7v]

[@brianamaldonado3433]

What does the 10E error code mean ?

[@GoPaschal]

You should check your owners manual for the brand you own, it will be specific to your make & model.

[@lazybiker234]

The flame in my tankless propane water heater occasionally goes out during operation. What is causing this? The propane tank is full. It does relight but goes out again after a few seconds.

[@geffreyacosta8821]

I have a EZTR40 and was getting error 121. After quick call to Noritz had it up and running in 10 minutes! The rep told it was really error 12 where it would ignite and then shut off. He walked me thru cleaning the flame rod and ignition plug with a DOLLAR BILL, could of used a Scott pad but did not have dry and clean one. Don't hesitate to call Noritz great customer service.

[@debramurray4412]

if u have a problem with the heater leaking in the pan does it have water in pan

[@myothercarisadelorean8957]

So what is the pro of getting a tankless compared to tank? Space? I can see that a standard tank water heater takes up room but there's really minimal mechanically parts and no computers. Tankless issues sounds like home computer nightmare.

[@johnw4590]

I just replaced my 17 year old Ruud with a Navien ..now I have major hot water flow restrictions. Can't wash clothes and take a shower... I never had this issue with the Ruud unit..

[@iceweaseltv]

My npe-210s keeps tripping the receptable breaker at night. Seems to only happen at night for some reason... and happens 2-4 times a month

[@lsmostwantedGamingGroup]

How do i manage my gpm.. I wrk at an fine dining establishment?? 2 min is all i get and then E110🤦🏿🤦🏿

[@JohnDoe-xr5de]

Water only gets warm when turned all the way up. This is a brand new unit also. If i even slightly turn it down water goes cold. Please help

[@Robloxð]

What would cause my tankless waterheater to have a combustion failure and shut off ?

[@GoPaschal]

Possibly a gas supply problem, but impossible to know without inspecting the unit. I would call your local plumber to have a professional take a look.

[@JimLindsey-yq2wy]

This was an exact replacement for the old one that lasted about 10 years. kzbin.infoUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).

[@kylekill4954]

Thanks for comment That is exactly what happened Snow covered vent tube

[@wjcbartley7364]

Hello sir I just hooked up a on demand water heater brand new it's making hot water but my water pressure pulses from Nealy no water to a ample flow then it slows way down like three times a minute... why?

[@sunnyvasquez3678]

If you have a dishwasher going or maybe sprinkler system. Change schedules for one or both. Good luck.

[@loricarter1720]

E5 error on my EcoSmart Eco27 tankless water heater

[@cannachrissd]

What happens when you get hot water but it's only when the flow is slow. When I open the hot side more it gets cold again. Like the hot water is passing too fast before it can get up. Is there like another valve i need to add so it will keep the water inside long enough to get hot?

[@bonfacekimeu1228]

What happens my anablaeir shower indicating E1

[@ronaldjackson764]

How can your water b 2 hot, just start the cold water 1st.

[@shoyrushoyru]

water that is too hot risks scalding the user and damaging pipes and stuff. it should be hot but not like kill-you-and-melt-your-appliances hot

[@sham1234567891]

Hi. Sorry. Background music louder than voice. Please fix. Thanks.

[@imranshaik1]

Heater is not igniting if opened in shower head 🚿 but works in botton tap and kitchen, how to fix this?

[@CubbyTech]

It's possible that there isn't 'enough' hot water being called for (0.25gpm) in a super-water saving shower head so it may not 'see' that you are using hot water

[@PeterNtheWolf]

Low water pressure below 35 PSI can also be the cause of no heat symptoms. Correlates to gallons per minute.

[@GoPaschal]

You're right that can also be a cause.

[@yaknowwhothis5102]

Had a issue with my brand new unit not giving up hot water for more than 30 seconds and no heat . Saw a vid on cleaning the cold water inlet filter and pulled it out and found it was clogged with sediment cause a friend didn’t install a sediment filter on my well before firing everything up. Cleaned it and now it works great

[@melissagore6059]

No hot water

[@bradleydoty2995]

Water to hot even though temperature set at 95

[@truthreigns369]

[@johnnyboy7407]

[@cliffcernuto5791]

[@DrFeeluponya11]

[@ricksingh3671]

I removed this tankless pos from my home today after 6 months, and installed a water tank now I feel like I am in Jamaica in December. Not worth it, keep your water tank
