cleaning solution into the Extruding Head until the
Evaporator Assembly and the Reservoir are full
and the solution overflows into the Drain Pan. Replace Spout A &
B, and the Storage Bin Cover.
Allow the icemaker to soak for 10 minutes.
**Use a 15mm socket to easily remove thumb screws.
In bad water conditions, a more thorough cleaning may be
required. Remove the Float Switch from the Reservoir cover.
Clean the Float Switch with the solution, rinse thoroughly with
clean water, and replace it back in the cover. In addition to
following Step ❹, place a clamp on the Reservoir hose that will
block the flow to the evaporator assembly. Pour additional
cleaning solution over the Extruding Head until the Evaporator
Assembly is full. Allow to soak, remove the clamp before
