What E12
actually means.
On U-Line's outdoor clear ice model, E12 (displayed as 12) means the water level is low. Without enough water over the evaporator, cubes come out thin, partial or not at all.

What to do when E12 shows on the ice makerKind of codeWater supply and fill
The ice maker asked for water and got too little, too slowly or none at all, or water kept arriving after the fill should have ended. A closed shutoff, a kinked line, a clogged filter and low house pressure are ruled out before the water inlet valve is replaced or the fill tube is thawed. If water is on the floor, close the supply valve before reading anything on the display.
Usually leads toIce maker water inlet valve repair
The electric valve that lets water into the ice maker, tested and replaced when it will not open, opens only partway, or keeps dripping after it should have closed.
Shows up asNo Ice Coming From the Ice Maker
The mold sits empty or holds one frozen batch that never drops, the bin stays bare for days, and the dispenser gives water as usual: an ice maker not making ice while the rest of the appliance carries on normally.

Make sure the water shutoff to the unit is fully open and the supply line is not kinked.
In cold weather, check that the supply line has not frozen; the outdoor model must be winterized below freezing.
