In most cases you will need to just adjust the float (grab the metal shaft and bend it downward) this will lower the water level. If this doesnt do it, then you probably need to replace the entire float assembly. This is normally a n easy and cheap thing to do.

Does it come back on automatically and how long does it take?

Yes you can. I have that set-up in my house. The only problem is when moisture laden swamp cooled air goes past the heat exchanger. This could cause the exchanger to rust out, allowing carbon monoxide to come into the house when the heater is used. This can be avoidid by having a one way damper made by an HVAC shop, and installing it at the heater.

Electrical issue. sounds like a bad relay, loose wire connection.

If your motor only works on low speed and not on high speed first check to see if you have the proper voltage to high speed. Check with a voltmeter or multimeter, check from common on the motor to high speed on the motor at the switch. If you have the proper voltage then you have an open winding on high speed and the motor needs replaced. If you don’t have the proper voltage or any volts, then the switch is bad and needs replaced. This also will be the same if, medium speed won’t work and low speed does.
