Water heater won't heat water - 2016 Cedar Creek 34RE

Wrong, not on this heater, there is no switch to run it on 120 AC, it only runs on propane

OP has a tankless WH. No tank. No electric.

Do you have an outdoor shower? Make sure the valves are off. If left on, it causes the hot and cold to mix and u don't get hot water.

If you haven't accounted for proper flow of water from the heater (flow switch not closing) you won't get water to heat as the gas safety valve on the unit won't open. Check for voltage at the gas safety valve on the heater if none present try flushing the water tank and lines if the lines are clear you have a bad flow switch.
