What 30 8 05
actually means.

On Classic (BI) built-in models, 30 8 05 means the main control got no signal from the ice maker telling it to open the water valve. On Designer integrated models the same code is worded as no water valve in signal. Either way the ice maker is not calling for water, so no new cubes form.

Questions
about 30 8 05.

Can I clear 30 8 05 myself?
Check that the ice maker is switched on and that the freezer is set to 0°F or colder. If it comes back, it needs a visit.
What does 30 8 05 mean on a Sub-Zero built-in?
The ice maker did not send the signal that asks the control to open the water valve. Without that request the mold stays dry and the bin stops filling.
Can a warm freezer setting cause 30 8 05 on a Sub-Zero?
It can play a part. Sub-Zero's first check is that the freezer is at 0°F or below, because the ice maker waits for a cold mold before it harvests and asks for more water.
Is 30 8 05 on a Sub-Zero the same as a water valve problem?
Not necessarily. The code points at the missing request from the ice maker, so a technician tests the ice maker module and its wiring before replacing the valve.

Still showing 30 8 05?

Book with the code or the blink pattern written exactly as the ice maker shows it, the full model number, and whether there is any water on the floor — when there is a code, that is where the diagnosis starts.
