Proper maintenance of your Hoshizaki refrigeration and ice machines is essential to ensure optimal performance, extend equipment lifespan, and maintain food safety standards. The following instructions are therefore for general guidance only.
Please refer to the correct user manual for further instructions for your ice machine, ice bin and refrigerant.
Ice Machine Maintenance
WARNING
Before carrying out any cleaning or maintenance operations, unplug the icemaker from the electrical supply network.
This appliance must not be cleaned by use of a water jet.
Ask a trained service person to clean and sanitise the icemaker water system at least twice a year and to check and clean the condenser at least once a year.
To prevent possible damage, do not clean the plastic parts with water above 40°C or in a dishwasher.
Do not use any alcohol for cleaning/sanitisation of the icemaker. It may cause cracks on the plastic parts.
For spare parts information, contact your local Hoshizaki service agent.
CAUTION
When using a neutral cleaner or sodium hypochlorite, thoroughly read and understand the instructions provided to prevent potential health problems.
CLEANING
[a] Machine and Bin Exterior
Wipe the exterior at least once per week with a clean, soft cloth. Use a damp cloth containing a neutral cleaner to wipe off grease or dirt.
[b] Scoop and Storage Bin Handle Cleaning/Sanitisation (Daily)
- Either mix 1 of water with 4 ml of 5.25% sodium hypochlorite solution in a suitable container, or the recommended Hoshizaki sanitiser as directed.
Guide only – please refer to the machine user manual for further details - Soak the scoop in the solution for more than 3 minutes. Rinse thoroughly and shake to remove surplus liquid.

- Soak a clean cloth with the sanitising solution and wipe the handle. Use fresh water and a clean cloth to rinse/dry.
- Clean every surface of the door gasket which gets soiled easily. It is readily removable for cleaning.
NOTICE
Hoshizaki recommends various types of storage bin for the icemaker which vary in size and design. The following instructions are therefore for general guidance only.
Please refer to the correct user manual for further instructions for your ice machine and ice bin.
[c] Storage Bin Interior Cleaning/Sanitisation (Weekly)
- Open the storage bin door and remove all ice.
- Wash the bin liner with a neutral non-abrasive cleaner. Rinse thoroughly.
- Soak a clean cloth with the neutral cleaner, and wipe both sides of the slope and the door inner surface. Wipe off the cleaner with a clean damp cloth.
- Either mix 3 litres of water with 11 ml of 5.25% sodium hypochlorite solution in a suitable container, or the recommended Hoshizaki sanitiser as directed.
- Soak a clean sponge or cloth with the solution, and wipe the bin liner, bin door and slope.
- The remaining solution can be used to sanitise utensils.
Note: Do not wipe dry or rinse after sanitising but allow to air dry.
[d] Air Filter
Plastic mesh air filters remove dirt or dust from the air and keep the condenser from getting clogged. If the filters get clogged, the icemaker’s performance will be reduced. Remove and clean the air filter(s) at least twice per month:
- Slide the air filter off the filter
- Clean the air filter by using a vacuum cleaner. When severely clogged, use warm water and a neutral cleaner to wash the air filter.
- Rinse and dry the air filter thoroughly.
NOTICE
After cleaning, be sure to place the air filter back in position.
Some machines differ in how the condenser screen is removed for cleaning, refer to your machine user manual for details.

Please refer to the correct user manual for further instructions for your ice machine and ice bin.
CLEANING – AIR FILTER
Plastic mesh air filters remove dirt or dust from the air and keep the condenser from getting clogged. If the filters get clogged, the refrigerator/freezer’s performance will be reduced.
Check the filter at least twice a month. When clogged or when the temperature controller shows “cH”, use warm water and a neutral cleaner to wash the filter. Do not operate the unit with the air filter removed, or the condenser will get clogged, resulting in failure.
- Remove the screw under the front panel and open the front panel or slide out from plastic housing.
- Remove the air filter from in front of the condenser.
- Wash the air filter carefully with cold or warm water containing the proper amount of neutral cleaner. Rinse and dry the air filter thoroughly.
- To refit the air filter, put the two tabs into the heat exchanger line or fins in the condenser, and tightly attach the air filter over the condenser or slide back into condenser screen housing.
NOTICE
After cleaning, be sure to place the air filter back in position. Some machines differ in how the condenser screen is removed for cleaning, refer to your machine user manual for details
