Ice Clumping Together in Ice Bin

If ice is not used regularly, it will fuse together; this is considered normal operation. You may need to discard the ice and allow ice to replenish.

1. Check the freezer temperature.
   • If temperature is above 5°F, ice maker will not work properly.
   • Sub-Zero recommends a freezer temperature of 0°F.
2. Clean the Condenser if it has not been cleaned within the last 3-6 months.
3. Make sure the ice bin is installed properly.
4. Make sure doors and door seals are free of tears and debris.
5. Always leave the ice maker on.
6. The more ice is used, the less it will clump – if unused, even for a period of a few days, ice will fuse together as the freezer runs through defrost cycles.
7. Empty, rinse, and dry the ice bin 1-2 times per month in order to remove the ice particles.
8. Replace the water filter as needed, if present.
9. Make sure water pressure to unit is steady between 20 – 100 psi.
10. If ice continues to clump, more than normal clumping from not using ice, service is needed to expertly diagnose and repair the unit. Contact Factory Certified Service to schedule an appointment for repair.
