no idea what "wicking" is.
the water level is NOT measured.
the ice makers fill on a time fill basis. As the ice maker is near the end of its cycle, the big white cog on the end (that contains contacts underneath) operates the valve for something like 5 or 6 seconds, then shuts off completely. no dripping should occur, ever.
for the dripping, if it drips direct from the fill tube, this can only be valve seepage. replace valve/s.
(possibly drips faster when water is dispensed from the front)
this would also explain the fill tube blockage.
OR, if its dripping FROM the icemaker into the ice bin, check the underneath of the icemaker for the green paint lifting around the sides.
believe it or not, ivr had afew of these syphon out underneath the paint.
hope this helps.
