Why doesn't my Sub-Zero icemaker or water dispenser get water to it?
Make sure the freezer has cooled down enough after installation. Most Sub-Zero ice makers
won't produce ice until the temperature has reached less than 10°. On Sub-Zero BI and PRO48
series models you may not get any water if the filter is plugged with sediment.
Icemakers need about 40 psi to fill properly. Make sure the water supply valve is turned on. This
valve is usually located under the kitchen sink and has a 1/4" copper or braided line running to
the refrigerator. Turn it counter-clockwise to ensure the valve is open.
Occasionally, this fill tube may freeze. The way to check this is to remove the icemaker and look
at the tube. If it is frozen, you will probably need to replace the water fill valve. Verify that the
icemaker is plugged in and turned on. The wire or plastic arm will be in the down position if it is
on.
