Maintenance Tips

• Daily “Clean Due” cycle (non-negotiable): Run and complete the machine’s automated cleaning cycle every day. The unit will lock out operation until cleaning is finished, ensuring hygiene and protecting the freezing system.
• Nightly thaw mode: Allow programmed thaw cycles so product resets properly. This prevents over-hardening of ice crystals, keeps texture smooth, and reduces strain on augers.
• Clean rear air filter weekly: Remove and wash or blow out the rear condenser screen. A clogged filter is a leading cause of overheating, slow freezing, and shutdown warnings.
• Maintain 4–6 inch rear clearance: Ensure strong airflow behind the unit. Restricted ventilation is a common reason for “filter needs cleaning” and compressor overheating errors.
• Sanitize hoppers and augers regularly: Fully disassemble and wash hoppers, augers, faucets, and seals using mild detergent + approved sanitizer to prevent sugar buildup and microbial growth.
• Clean faucet assemblies daily: Remove sticky syrup residue from dispensing valves to prevent dripping, clogging, and inconsistent flow.
• Inspect seals and bushings monthly: Worn shaft seals or auger bushings are a common failure point and can cause leaks or uneven freezing performance.
• Monitor product mix (Brix) closely: Incorrect syrup concentration leads to freezing instability, auger stutter, or overly soft/slushy texture.
• Avoid low-product operation: Keep hoppers above minimum fill level to prevent air ingestion, freezing errors, and motor strain.
