What to do if Waeco MOBITRONIC MBC-16IU Battery Charger shows F04 charging error?

If your Waeco Battery Charger displays an "F04" error, it means the charger has overheated. You should clean any dirty ventilation openings or remove any objects covering the device. Move the charger to a cooler location. It will restart automatically once it cools down.
