1. Hoshizaki Maintenance Schedule

   Maintenance Frequency	Recommended Maintenance Tasks
   Daily	Check ice quality and production Listen for unusual noises or beeping Wipe down exterior surfaces and wash the ice scoop
   Monthly	Check the psi on water filters Wash the exterior with dish soap and damp cloth Clean bin door with warm water and cloth
   Every Six Months	Clean and sanitize the ice machine Descale mineral buildup Inspect water lines and filters Clean condenser coils
   Annual	Schedule professional maintenance Inspect electrical components and connections Check refrigerant system performance Replace worn components

2. Cleaning and Sanitization

   Cleaning and sanitizing your Hoshizaki ice machine is crucial for producing clean, sanitary ice and preventing mold and bacterial growth.

   Quick checks for cleaning:

   • Shut down ice production and safely remove ice
   • Clean the machine to remove film and debris
   • Descale with a Hoshizaki-approved descaler and run a wash cycle (available on most models)
   • Remove tubing to drain the descaler solution; reconnect and run an ice cycle
   • Run 2 to 3 ice batches of ice after cleaning and sanitizing

3. Component Inspection

   Hoshizaki ice machine components should be inspected at least every six months. For environments with hard water or high usage, a technician may inspect the machines more often.

Quick checks for component inspection:

• Check the water filter pressure gauge; replace if the pressure is low or it hasn't been replaced in six months
• Wipe the float switch at least every six months to remove scale buildup
• Check the bin control sensor for ice buildup or damage
• Inspect water supply lines for leaks, cracks, and insecure connections
• Ensure the drain hose isn't clogged and clamps are secure
• Rinse the air filter with water; allow to dry completely

4. Operational Checks

   Operational checks ensure the unit is producing ice efficiently. Some checks should be performed in a sequence.

Quick checks for operations:

• Check initial power-up to ensure the fill cycle works properly and the float switch detects water
• Ensure the ice maker has normal harvest and freeze cycles
• Inspect the float switch for cleanliness; a dirty float switch can cause long freeze cycles or small ice production
• Confirm the machine shuts off when the bin is full
• Listen for unusual sounds

5. Preventative Maintenance

   Preventative maintenance maintains ice quality, improves efficiency, reduces breakdowns, and extends the life of the Hoshizaki ice machine. Use Hoshizaki-approved cleaners or a non-ammonia-based solution.

Quick checks for preventative maintenance:

• Clean the air filter every two weeks
• Replace the water filter(s) every six months
• Clean the condenser every six months
• Clean and sanitize interior components
• Wipe down the exterior with dish soap every four weeks
