Task
Clean the ice scoop using a neutral cleaner. Rinse thoroughly after
cleaning.
Inspect. Wash with warm water and neutral cleaner if dirty.
Check for proper pressure and change if necessary.
Wipe down with clean, soft cloth. Use a damp cloth containing a neutral
cleaner to wipe off oil or dirt build up. Clean any chlorine staining (rust
colored spots) using a non-abrasive cleaner.
Clean and sanitize per the cleaning and sanitizing instructions on the
appliance or in the instruction manual.
Wipe down with clean cloth and warm water. Slowly pour one cup of
sanitizing solution (prepare as outlined in the sanitizing instructions on the
appliance or in the instruction manual) into the evaporator condensate drain
pan. Be careful not to overflow the pan. The solution will flow down to the
gear motor drain pan and out the drain line to sanitize these areas. Repeat
with a cup of clean water to rinse.
Check to make sure they are clear.
Inspect for leakage around seal bolts.
Tighten (11.1 ft-lb/15 N·m) or replace as necessary.

the inlet water valve screen and clean and inspect the drain valve.
