Re-starting your Ice Maker after a Downtime

Ice Maker Re-Start Tips

If you want to re-start your Ice Maker after a longer downtime, there are some simple steps you can follow to make sure, that the inner parts of your machine are absolutely clean and ready to produce perfect Hoshizaki ice. The goal is to flush the inner workings as well as getting rid of all excess water that might have been trapped inside. Making sure that all remaining water is flushed is an important step to prevent contamination and machine defects.

1. Replace Filter

Replace your existing water filter cartridge with a new one.

2. Flush Filter

It is important to let the water run for 5 minutes to activate the filter.

3. Clean bin and accessories

Our recommendation: Mix 5 liters of water with 18 ml of 5.25% sodium hypochlorite solution in a
suitable container. Alternatively, you can use the recommended Hoshizaki sanitizer as directed on the packaging.

4. Clean air filter

Using a damp cloth, clean air filter thoroughly.

5. Connect Ice Maker

Push the start button and stand close enough to be able to hear any unusual sounds, as the machine is starting.

6. Listen Up!

Stand close to the machine to identify any possible unusual sounds, as the machine is restarting.

7. Discard first-day batch

To make sure to use only absolutely clean ice, let the machine run for 24 hours and discard the entire produced ice batch.

Things to look out for:

  • Unusual sounds: If you notice any unusual sounds, it could be a sign of a machine defect. Please turn off the ice maker and contact your local dealer immediately.
  • Unusual smell: the odor of food-safe ice is absolutely neutral. However, if you notice a smell in/around the machine or the ice itself, do not – under no circumstances – use the produced ice for consumption. Please turn off the ice maker and contact your local dealer immediately.  as unusual odors can come from leakage and/or bacterial contamination.
