What does it mean when the Blue light on the Smart Drinking Fountain is flashing?

If the light of the water dispenser is blue, it means that the water dispenser is short of water. It's a reminder to add water in the dispenser. At the same time, the water pump will automatically stop working in case of water running low in the dispenser. So remember to refill the dispenser with water if you see Smart Drinking Fountain flashing in blue .
