If your water dispenser is running continuously, it could be due to a few different reasons. The most common cause is a leak in the dispenser tubing. This can be caused by a loose connection, a crack in the tubing, or a clog. Another possible reason is that the float switch is stuck in the on position. This switch is what tells the dispenser when to turn on and off, so if it's stuck, the dispenser will just keep running. Lastly, it could be an issue with the dispenser motor itself. If the motor is faulty, it may not be able to turn off even when the switch is in the off position. If you're not sure what's causing your water dispenser to keep running, it's best to call a plumber or appliance repair technician for help.
