As far as I know, tankless water heaters fire up when the water pressure DROPS 9opening a faucet). Having FLOW won't achieve that. I have never heard of having a recirc system on one of those water heaters, only with a tank. You would have to ask the maker of the water heater. I would say you have the wrong HEATER and SYSTEM for the application.

did water stop if not problem can be with install --or faulty valve https://www.reddit.com/r/Plumbing/comments/lzde4a/rheem_marathon_install_vacuum_relief_valve/

Please reach out to your local plumber.

since it is an on demand it will not heat water until called for. You cn bo to breaker box and turn off power if you wish.

your not making sense with you question --state it goes cold in middle of shower --but state it will stay hot or cold forever ----if its the latter continued hot till you shut off water that normal working if the unit shuts down during shower then you have a problem ----unit is set at one temp and runs at that temp and you use shower 1 handle / 2 valve what ever you own to adjust temp their are really only 4 reasons stops making hot water ----2 are usually well water supply --incoming water pressure /flow or to cold ----other are gas valve -or sensor so i would look into your shower handles since almost all have adjustments and anti scold safety

An E4 error code on your 45 model tankless water heater, indicates that there is an issue involving the flow meter sensor (also referred to as cold water temperature sensor.) This means that the flow meter is not sending a signal to the computer which starts the machine. Possible broken wire, poor connection or faulty sensor.
