Check your ice maker and make sure its level both ways.

If its level, check the ice mold for holes or corroded areas that might be leaking. (I've seen that a couple of times over the years.)

Its also possible the cam on the big white gear is burnt enough that the ice maker is overfilling.

The back of the ice cubes should never touch the bar that ejects them. They should be about 3/4 of an inch high at the tallest point.
