Viking 15" W Ice cubes are too small Low ice consumption, Less than 1/2 thick, Produce ice

TROUBLESHOOTING GUIDE

PROBLEM		POSSIBLE CAUSE	CORRECTION
Ice cubes are too small		Low ice consumption	Ice is slowly melting in the ice bin and will
(less than 1/2” thick)			affect the size of the ice cube. This is normal
			operation. When the ice bin needs to be
			replenished, cubes will return to regular size.
		Not enough water in reservoir.	Make sure that the reservoir drain plug is installed
			properly. Check the water line to the unit to make
			sure there are no restrictions or kinks in the line.
			Check all filters to make sure they are not restricted
			or plugged.
		Distributor tube is restricted.	See “Cleaning the Ice Machine System” section for
			cleaning the unit for proper operation.
		Build-up of deposits on evaporator	See “Cleaning the Ice Machine System”
		plate.	section for cleaning the unit for proper operation.
		Leaking drain valve	See “Cleaning the Ice Machine System” section for
			cleaning the unit. Cleaning the unit will also
			dissolve and flush out foreign material in the drain
			valve.
		Inadequate drain system.	Restriction in drain lines will cause ice in the bin to
			melt to a thinner cube. If using a gravity drain,
			make certain there are no kinks or restrictions in the
			drain lines. If using a drain pump, check the inlet
			screen, discharge line, and vent line for any build-up
			or restrictions.
		Room temperature is too warm.	Move to an area where temperature is below 90oF.
Ice cubes are too big	Ice slab not releasing.		See “Cleaning the Ice Machine System”
(greater than 3/4” thick)			section for cleaning the unit for proper operation.
		Condenser fan air flow is restricted.	Make certain the grill in the front of the unit is free
			and open for proper air circulation. Check and
			clean the condenser coil by removing the grill in the
			front of the unit. Clean the condenser with a
			vacuum and brush attachment.
		Room temperature is too warm.	Move to area where temperature is below 90oF.
Hollow ice slab		Distributor tube is restricted.	See “Cleaning the Ice Machine System” section for
			cleaning the unit for proper operation.
		Build-up of deposits on evaporator	See “Cleaning the Ice Machine System”
		plate.	section for cleaning the unit for proper operation
			and cube size.
		Low water level in reservoir.	Make sure that the reservoir drain plug is installed
			properly. Check the water line to the unit to make
			sure there are no restrictions or kinks in the line.
			Check all filters to make sure they are not restricted
			or plugged.
Unit continues to run		Ice bin is not full.	The unit will automatically shut down when
and produce ice.			ice reaches the sensing tube.
		Ice bin is full.	The unit will automatically shut down when ice
			reaches the sensing tube and has completed the
			harvest of the ice slab.
		Room temperature is too warm.	Move to an area where room temperature is below
			90oF.
		Ice machine is not level.	Use a level to check the unit from side to side and
			front to rear.
Ice cubes are sticking		Ice consumption is low.	Use the ice in the bin frequently. Ice will stick
together.			together if left in insulated bin over long periods of
			time.
		Room temperature is too warm	Move the unit to an area where temperature is
			below 90oF.
