A shallow well might make it to shut off pressure, but not a deep well. It maybe doubtful that a 240v pump will run on 115v, but it does happen.

You would be surprised. I have had them working that way for years. They just won't build enough pressure to shut off.

Check the voltage at L1 and L2 either on the outlet side of the pressure switch or at the control box.

Make sure you have 240 volts to the pump. Half power or 115 volts can make it act that way, and could have happened during a power outage.

It sounds like your pump or well is not producing enough water.
