What D8 blue LED flashing slowly
actually means.

The blue D8 light is the water level indicator. Steady means the probe is touching water; a slow one-second flash is the water lack protection, set when the probe stays dry for 5 minutes during freezing. Atosa's list: no supply, a closed ball valve, a leaking trough, the inlet valve or the probe.

What to do when D8 blue LED flashing slowly shows on the ice machine

Before you book,
in this order.

Each step comes from Atosa's own guidance for D8 blue LED flashing slowly on its ice machines. Follow it to the end: the last card says whether this is a visit.

01

Check that the ball valve on the water line is open and the supply is on.

02

Check the included water filter for a clogged cartridge.

03

Look for water leaking from the trough inside the door.

04

If the blue light keeps flashing with water available, book a visit to check the inlet valve and probe.

What not to do

A steady blue D8 is normal and means the probe sees water. The Atosa manual numbers this protection differently in two sections, so go by the light, not an E number.

Questions
about D8 blue LED flashing slowly.

Can I clear D8 blue LED flashing slowly myself?
Check that the ball valve on the water line is open and the supply is on. If it comes back, it needs a visit.
My Atosa manual calls water shortage E3 in one place and E4 in another. Which is it?
The manual contradicts itself, so use the light: a blue D8 flashing once a second is the water shortage protection on this board.
Can a leaking trough make the blue light flash on my Atosa?
Yes. Water escaping from the trough keeps the probe dry, and Atosa lists it among the causes.
What should the blue D8 light normally do on an Atosa?
Stay on while the probe is in water and go off when it is not. Only the slow flash signals the shortage protection.

Still showing D8 blue LED flashing slowly?

A booking with a code goes further when it carries the light or code copied as it appeared, the model and serial off the data plate, and a word on whether cubes still fall into the bin. With those three in hand, our office can match the probable part to your machine the same afternoon.
