2022 on-demand water heater won't turn off on shore power

I've noticed that my on-demand water heater on my 2022 FC 27fbt doesn't turn off when on shore power. I push the button - it beeps - but doesn't turn off. As a result it pretty much stays in E1 all the time when I'm just prepping for a trip - and I assume tries to keep lighting.

Am I doing something wrong?

Thanks,
Scotty

Does ON mean standby ready to heat when the water flows? (for how you're describing it)

If you have propane on does it get hot with no water running?

Can you turn it off while not plugged in (just on battery)?

The on-demand water heater should not have 120v hooked to it.

There's an on/off switch on the outside of the unit you can use to shut it down.

So...I guess it is ON standby waiting for water to flow. I don't have the propane turned on - and caught it trying to light earlier today. There is no water in the tank, not hooked up to city water and the pump is OFF. It is a little cold here - but not in the 30's to activate the freeze guard behavior (although it was last night).

I went and disconnected shore power - but left the battery in the ON state. The behavior didn't change - so shore power isn't the problem.

The On/Off button is ON (illuminated) on the Control Panel - it won't go off. Screen says E1 because it tried to light and had no propane.

Thanks,
Scotty

Mine does this as well. The manual says it's supposed to go into a lockout mode until reset if it fails to light twice, but mine seems to keep trying to light with E1 on the display

To sum it up - I guess the only way to completely turn it off is to turn off the water heater's power switch on the outside of the trailer OR put the trailer in store mode. That's not what I expected - but at least I think I understand it now.

Thanks,
Scotty

When I push the on off switch on the wall it turns it on. If you click the button again the screen will go dark and places the unit in (off) or more of a sleep mode, it won’t ignite and heat when you turn on the water. It will continue to protect itself against freezing until you turn off the switch on the unit accessed from the outside. If your in Texas, I don’t recommend turning off the outside switch. Your unit can possibly freeze if the temps drop.

Hi

To protect from freeze you also need to have the propane hooked up and turned on.

Normally these "self protect" gizmos cut in well above freezing. You get into the low 40's or high 30's and they start doing their thing. They run for a bit, heat up above (say) 50 and then coast back down.

It just a bad bad unit-

Bob I hate our Girad, the biggest most disappointing thing Airstream could do to its customers. I am reaching out to anyone who has replaced the unit with a Truma. I am hesitant because they do not have a exact fit outside door. The Truma is so superior on heating. Real warm water on demand efficient and no cold water shocks no excuses, it just works. Our other trailer with the good old 6 gallon gas /electric was a better unit.

It definitely works that way while the propane is on. But if you turn off the propane, it can get into a cycle of trying to restart all the time - and I couldn't find any combination to keep it from cycling.

The trailer is currently winterized, so I'm not worried about freezing. We are packing it up for a trip, and have the trailer on to get the fridge cold and packed. Since I plan to drive with the fridge on, I prefer the water heater to just be just be off.

Thanks,
Scotty

Yes Truma has an exact fit I replaced my Girard with a Truma. Make sure you order a XS door (extra small). No cutting of the aluminum siding or rub rail! All you need is some, butyl tape, plex pipe and valves for a winter bypass. I ordered a black door and it looks great and works great.

Yes the outside switch is the only way to turn the pump "off". As far as I can tell, the inside light simply tells me the position of that outside on/off switch. Mine also continues to try to light when the propane is off, until I flip that outside switch. It's actually valuable because that switch allows you to travel with your propane on (fridge, furnace, etc) if you are so inclined, without worrying about your water heater lighting. By the way, I'm not unhappy with the Girard On Demand heater. No winterizing, less propane use, etc. Yes, I know it can give you a shot of cold if you're not paying attention, but on balance I'm OK with it. Depends on how you camp, I guess.

I'm glad I happened to see this thread. I have the same trailer that you have and I didn't know about the automatic freeze protection. I had to get out the instruction packet. I already miss my 6 gal. manual water heater that was in my older trailer.

Hi

That would be Truma ... the outfit that supplied the stuff that dies after running for 3 to 4 weeks in all of the new Interstate X's (including mine)? Replace it and it runs for another couple of weeks, then dies again.

I don't see any of these "brand names" as being perfection. I've been happy with the Alde in our Classic. Others have not been.

This sounds like there needs to be a step in the winterizing instructions to turn the outside switch on the water heater to off while winterizing and don't turn it back on till de-winterizing.
