Not likely water in basement had anything to do with the buzzer problem.
Chances are the buzzer itself is defective. Usually that part is the control itself.
Timer also could be the cause. When timer reaches the pre set location, it closes a contact switch to activate the buzzer on some models and brands.
Best bet is to replace the buzzer control. Located behind the control panel. Be sure electrical power is turned off and or the power cord is removed from the wall outlet.
