Check for reverse connection and cross connection.

If you use the remote controller, is the power button turned on?

Check if the inlet water temperature is too high. If it is too close to
the set temperature, the water heater won't work.

Is power available to the unit? If so, is the power button on the
controller or inside the water heater turned on?

still spinning after

running from 15 to 70 seconds in order to re-ignite quickly, as well
as purge all the exhaust gas out of the flue.
