Check if there is water in the water tank. If there is no water, add purified water from the injection area and add it to the normal water level

If there is water in the water tank, check if the pump in the tank is in the water. If not, put it down a little bit so that water can be pumped out

in short

DI8 alarm means water shortage in the water tank
