Great video! I verified my water flow, then checked again the unit and still no heat. The display showed no water flow. It had acted like a loose connection, working then not working. Once I ruled that out I was going to disconnect the flow sensor to see if it was stuck, as I was on the road with no multi meter. Before taking anything it apart I open the high temp relief valve to see if that might flush out any grit. Luckily that fixed the stuck/sticking flow sensor. It has worked flawless for two days now.
This is an incredibly helpful video. You helped me to understand the steps and trouble shooting steps logically. We have this heater and currently the shower is the only place that doesn’t fire up the water heater. Every other facet can call for hot water successfully. We do have a pretty hard water. Somewhere in my shower system the water flow isn’t enough to “call for water”. Thanks again for the very well done video. Subscribed to support you and your channel. Keep it up. 👊
Thanks for the information I had the problem with the outside shower. Hot on shower head off. Finally did enough reading and videos to figure it out. 8 month new rv owner, still learning.
Love your channel!! So helpful!!.... I have a question about an issue I'm having with my RV fridge....it was working fine until recently, but now it's not cooling on propoane? I've cleaned and checked the Jet and the Burner tube.....I'm getting nice blue flame, (not very loud though? Not sure if it should be?) but for some reason the fridge isn't getting cold on propane? However it will when I run it on the generator? Any ideas? Is it an airflow issue? Thanks.
Followed your algorithm. Propane, water pressure, etc all perfect. Measured pins 2 and 3 at 4.9V when unhooked from the flow detector. Checked at all harness points. 4.9V. consistently. However once the harness is connected to the flow detector measurement drops to zero, therefore no way to detect a further drop when hot water is turned on (Klein tool, professional electrician). What now? And thank you!
Great videos! Do you have a video or plan on making a video of stuff you keep on hand, like sealants, or awning motors or anything like that?? Thanks again
I've had this tankless water heater for over 6 years. Never had to mess with the water control valve. Our water tank is on the exterior of the unit. This makes for some very cold water (45-50 Degree Fahrenheit) coming into the system, and maxing out at the faucet at about 102 degrees. Recommendation was to decrease the water control valve allowing more time for the unit to heat the water. How much does this turn, as it appears to only turn about a quarter turn max, unless it is stuck?
What DC voltage setting for the test? Different numbers on my meter. 500, 200, 20, 2000m, and 200m. I checked on every setting with no water running. Didn't get any voltage on the higher settings. Got way different readings than 5 volts. So, bad valve right?
Hi, I was searching for tankless water video issues and your video showed up. You have several Rv tech videos that I will be looking at. My question is I just a new 5th wheel a week ago that has tankless water heater. This all knew to me. Took it out camping for the first time. I have set at 115 but the temp went up to 122 as soon as I introduced cold water to balance it temp the heater shut off and got cold water. I’m doing something wrong ? Or is the water bad and take back to the dealer . Thank you
You are not supposed to use your cold water tap to adjust your water temperature at your sink or shower -- you only set the temp on the water heater, and use only the hot tap. If you ran the cold water, it messes with the water flow through the heater and it makes bad temp adjustments like this.
My Girard heater will heat water, but as you attempt to adjust the water temp, it will either completely shut off the water heater, or go as hot as it will get. There is no in between with a comfortable temperature. Any help on this issue would be much appreciated.
The gas is full and the water pressure is good also and it shows on the panel inside the RV. I have it set to 105 but it only reaches like 99° like I say it gets hot like go to 103 104 and then it goes right back down to 99 and stays there.

You are an excellent teacher! Thank you so much for this video

You’re VERY good at what you do!!!…
And, i watch you EVEN if what you’re talking about has nothing to do with my R.V.
Thanks for the information

When I initially turn on my water it gets hot and then returns to Luke warm! Could you maybe know already my issue?
The gas is full and the water pressure is good also and it shows on the panel inside the RV. I have it set to 105 but it only reaches like 99° like I say it gets hot like go to 103 104 and then it goes right back down to 99 and stays there.
What happens if the hot water is not staying at the temperature I set it. The hot water is going to high.
"Sucker" ? What's that. Very informative video with nomenclature that is mostly clear. Just the facts without attitude and acting would be nice.
