Ice Maker is overflowing and leaking into the ice bucket: There are several things to check for.
Go for the easy stuff first, make sure the icemaker is level, some of the plastic liner fridge's will move and allow the icemaker to tilt over and leak. Other troublemakers..... the fill valve
staying on and over filling the icemaker..... the finish sometimes comes off the icemaker body and all the ice cubes don't come out. This will allow the new water to fill on top of an icemaker
that still has a ice cube or two left inside the body, if you have had trouble with black specs in your ice cubes, this may have been the beginning of your finish problem on the icemaker body.
On the module style ice makers (Whirlpool, Maytag Family, Sub Zero) the printed circuit in the
module head often wears and the contacts become too long and allow the icemaker to over fill = new ice maker or new module head.
Older style icemakers: This gear is bad for breaking and the icemaker quits turning to eject the ice.
You can remove the front cover to see the gear.
This is a common parts breakdown of the older style icemakers
Water fill volume: The water fill adjustment screw will change the fill volumes by changing the fill time.
One half to one full turn usually ( approx ) is equal to 20cc ( 0.68oz ) to 40 cc.
The correct fill is usually 130 to 150 cc ( 4.5 to 5.0 oz ).
When a water valve is replaced the fill volumes must be re-checked!http://www.SubZeroLosAngeles.com
