Does your WH look like the one pictured in post #22? If so, it should have a small, almost invisible button as shown.

It is similar but different in the fact that it doesn't have that plate with the reset button. Trust me I have looked, 3 service tech's have looked and couldn't find one. One of them called the mfg, and some were made without the reset button.

That is true. Some don't have it. Mine doesn't and I spoke to Girard to confirm.

So does no reset button mean it does not have the low flow/high heat safety cutoff, or does it reset itself somehow?

I guess going by the manual you can wait 5 minutes, or shut off the power for 5 seconds and turn it back on.

I had assumed that the knob in the vanity was to control output water temperature. Apparently, it controls the flame - so if the flow is a certain rate, and the flame is too high, the high temp cutout shuts off the water heater, thus the cycling of hot-cold-hot-cold in the shower. I turned down the knob on the wall (pointer at about the 9 o"clock position) - and haven't had an issue since.

Tankless Water Heater Replacement

Then the water went to ice cold. I complained to Jayco and they replaced the tank-less setup with a regular tank. This is a serious safety issue if you have small children. According to Girard the tank-less heater was in fact working correctly it "limits out" at a specific temperature. There is no thermostatic control on the output of the unit to dynamically regulate the output temperature. Home tank-less units are designed to keep a temperature set point and will adjust the flame to achieve this. The Girard units have a manual flame adjustment and as the flow drops they will either cycle hot cold due to limiting out or shut off altogether. The user must manually adjust the flame to achieve the correct temperature rise based on the input water temperature. If you are careful and open the faucet fully, set the correct flame and do not turn off the water during the shower or anticipate the scalding hot followed by cold if you do then the system can work well.
Good to know Jayco will replace the tankless Water heater with an electric/gas DSI unit. Wife and I seriously considering the Jayco Class A or C, but every model we want has the tankless Water heater, which is a deal breaker for us. Had the tankless model on another rv and had it replaced with the tank model.

We had 7, 14 & 18 year old grandkids (2 girls) with us for 2 days last week. Everyone showered. After they were introduced to how to operate the water faucets we had no problems. Our heater requires us adding a very slight amount of cold water to keep the temp at the faucet at a bearable level. There is some fluctuation in the water temp but no shocking variations.


When the WH quit (in March) we called Girard direct and they were incredible. Great customer service. In our case, they walked me through a testing procedure and then overnighted 2 parts, I installed them and we have had hot water on demand since.
When we bought our Precept, we had in the contract that if we did not do well with the Girard system, the dealer would replace with a 6 gallon DSI gas/elect. We still have the Girard.
If I were to build my Precept from beginning, I would opt for another WH system. There are new systems out there that provide reliable hot water.
Otherwise, we are really happy with Bertha after 5000+ miles & 15 states. We're just getting started.

Search tankless hot water for posts- we have a 2014 Seneca and the tankless has never worked right. It's a bad product for an RV that moves to different campgrounds and different water sources. We have a new water regulator on order that has a gauge on it that can be adjusted. We are hoping this helps.

Wife and I really like the Precept 31UL are will likely pull the trigger if we can substitute the tankless Water heater with the 6 gallon gas/electric. We have had the tankless in a fiver that never worked right. I know Girard has made a couple of improvements, but still a no go for us living in the south. The outside water coming in is usually very warm which means as soon as the water goes through the heater, it gets too hot and the system shuts off blasting you with cold water. No thanks.
