To reset your Fogatti RV Tankless Water Heater - Gas - Automatic Pilot - 41,800 Btu - White # LSB64FR you'll simply need to cut the power running to the unit. You can remove the positive power wire at your battery, at the unit, or simply remove the fuse from the unit which is part #26 in the attached photo.

I recommend letting the unit sit off for 15 minutes to full power down and reset before reconnecting the power.

@BenP When you turn the hot water faucet on are you getting a shower symbol on the wall controller? I'm going to send you a separate email so you can send me a picture of what it's showing.

I reset my Fogatti tankless water heater a few times over the past week. I have a full tank of propane and very good water flow. But for some reason I have to keep shutting off the power, removing the fuse, and turning off the power switch. I wait for 20 to 30 minutes. The first couple of times it heated the water, but now it doesn’t reset. All I have now is cold water.

@Thomas If you're providing the unit with everything it needs to function and it's still erroring out then you likely have a control board or sensor issue. Is it giving you an error code on the thermostat or just not working and saying nothing? I would give Fogatti a call and get a warranty note going for your unit since they don't really offer any parts separately.
