There are a few things you are going to need to check on your Fogatti RV Tankless Water Heater # LSB64FR.

You did mention there are no codes being thrown which is strange, however you'll still want to first check the voltage to the unit with a multimeter # PT89ZR. You'll need to be ensuring that 12VDC is getting to the unit. If not, that could be causing your issue, and you'll want to check your wiring/connections.

You're going to also make sure that you are checking out your grounds. Something as simple as a bad ground connection can cause a bunch of issues to your unit as this can lead to voltages spikes, which can damage your control board.

The last thing you can check is for a LP leak. If smell any type of LP gas smell there could be a leak at the combustion stage and could also be causing your issues.

Let me know if an error code shows up, or if you're still having issues and I'd be happy to help.
