Ice maker produces ice, but production is very slow and bin never fills to normal level.

Safety: Disconnect power before cleaning condenser or internal components.

Steps to improve production:

• 1. Clean condenser coil: Remove the front grille and thoroughly vacuum and brush the condenser fins.
• 2. Check room conditions: Ensure the room temperature is within Sub-Zero's recommended range and that the unit is not installed in a confined, unventilated space.
• 3. Run a cleaning cycle: Use Sub-Zero-approved ice machine cleaner to descale the water circuit and evaporator plate. Scale reduces heat transfer and slows ice formation.
• 4. Verify water flow: Observe the fill and circulation. Weak flow may indicate a partially clogged inlet valve or failing circulation pump, which may need replacement.
• 5. Monitor results: After cleaning and adjustments, allow 24 hours of operation. If production remains low, a sealed system or control issue may be present and should be checked by a technician.
