Resetting a residential water dispenser or cooler to clear electronic control glitches, heater faults, or pump errors involves performing a simple power interruption. First, unplug the dispenser power cord from the wall outlet and switch off the rear heating and cooling toggle switches. Second, leave the appliance completely unpowered for approximately five to ten minutes to allow internal control boards and thermal sensors to discharge fully. Third, plug the power cord securely back into the wall outlet and turn the rear switches back on. You can troubleshoot electronic freezes easily. You can verify that your reset procedure was successful when the indicator lights reboot, the internal water pump or heating tanks re-engage, and normal water dispensing resumes.
