On Classic Series (CL) models, 40 8 01 means the control counted an excessive fill of the ice maker. Too much water in the mold can spill into the bin and freeze cubes together into a block.

What to do when 40 8 01 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.
