We have a 2020 Legacy Elite II with a Truma water heater. This spring, we are unable to get it to heat the water. There are no warning codes on the panel or on the water heater. When you turn the water heater switch and panel switch to on, and watch the water heater, you can see the flame start. Hot air blows out. It will start and stop two or three times. Then when you go into the camper and turn on the hot water faucet, the water never gets hot. When you go look at the water heater, it looks like the flame is not starting and no hot air is being blown out. I would have decalcified it but we do not have any decalcification tablets. The propane stove and furnace work great.
Does anybody have any experience or ideas with this?
Thanks much, in advance!
