How do you adjust the ice thickness on a Hoshizaki ice machine?

How do you adjust the thickness of Hoshizaki ice?

The question regularly asked is “how do I adjust the ice thickness?” Fortunately the answer is easy. To increase the thickness you will slide the float switch down. If you need to decrease the ice thickness you will slide the float switch up.

How do I adjust the thickness on my ice maker?

After opening your machine, you should see the ice thickness sensor attached by a single screw. Adjust this screw one quarter-turn counterclockwise for a smaller bridge and thinner ice. Adjust this screw one quarter-turn clockwise for a bigger bridge and thicker ice.

What does the float switch do on a Hoshizaki ice machine?

The float switch on the KM unit serves two major functions in the operational sequence. This simple switch, provides an automatic reset, low water safety protection. It also, signals the control board to initiate the harvest cycle when a full batch of ice is formed on the evaporator plates.

Why is my ice maker making thin ice?

Lack of water going to the evaporator plate causes an ice cube maker to make thin ice cubes. Make sure the drain cap is securely in place in the reservoir. Check the water reservoir for a crack or leak.

How do you test a float switch on a Hoshizaki ice machine?

To check the float switch, disconnect the black float switch connector at the control board and check the switch for continuity. The reading should be infinity (8 ) when the float is down and (0) ohms when the float is up. It is typically better to do this by allowing the water to flow out of the reservoir.

What makes a hoshizaki go into harvest?

As the ice is being formed on the evaporator the level of water in the reservoir drops. Once it has dropped low enough to open the float switch the freeze cycle is terminated and the pump out or harvest cycle begins. During normal operation the water level must drop before the unit will go into harvest.

How does ice thickness sensor work?

It is triggered by water contact. Water contacts the sensor when the ice is at the proper size. During use the Ice Thickness Sensor will become coated with mineral scale from the water, which if left untreated can cause changes in bridge thickness.

Why is my Hoshizaki ice machine freezing up?

In Hoshizaki ice machines, a float switch controls the amount of water used during a freeze cycle. If the float switch malfunctions, it may cause the machine to make larger than normal ice, which is harder to release from the evaporator plate during the harvest cycle. This can lead to a freeze-up, as well.

Why is my Hoshizaki ice machine not making ice?

Check the power supply and fuse.



If the ice machine is not starting, check to see if it is plugged in properly and is in the ON position. Also check if there are any loose connections that need to be tightened and if the voltage is too high and needs to be replaced. If everything looks okay, check for a blown fuse.

Why is my ice maker not making full cubes?

Water flow



Too little water can cause the cubes to come out too small or hollow. Cause: A water filter that needs to be replaced can restrict water flow. Fix: This is a simple fix. Purchase a replacement water filter for your refrigerator, rinse the new filter and allow the ice maker to produce multiple batches of ice.

How do you make ice cubes bigger?

Rotate the screw in the direction indicated by the plus sign to increase the amount of water in the ice tray. Rotate the screw in the direction indicated by the minus sign to decrease the amount of water. One full turn of the screw increases or decreases the water by 40 cubic centimeters.

Why are my ice cubes hollow?

Hollow ice cubes can be caused by low water pressure. Low water pressure to the fridge will result in the ice maker filling too slow. This can make it so the ice cube mold does not have enough water in it when it begins to freeze the water to make the ice cubes.

How does an ice maker know when to dump the ice?

A signal is sent to halt that process when an internal thermostat indicates the cubes have reached 5-9 degrees Fahrenheit. After the cubes have been created, a heating coil is activated to loosen them from the molds.

Why are my ice cubes wet?

To have the freshest ice possible, cubes are constantly melting in the ice bin as new cubes are being produced. This is normal. Cubes may be wet/watery because water drips from the cutter grid and into the ice bin during the ice harvest cycle. This is due to the process of cutting the ice slab into cubes.

Why does my ice stick together in my drink?

The interface between the ice and the liquid (the surface of the ice cube) is cooled by the ice cube, but heated by the liquid. The ice cube heats up in this process and the liquid cools down in this process (which is the main reason why you put the cubes in your drinks anyway).

How do you make ice not stick together?

Whether you make your ice at home or buy it from a store, storing it in paper bags will keep it from sticking. Just fold the top down tight to eliminate as much air as possible. Some sources say this trick works because the paper can absorb any extra moisture the ice cubes give off. It makes sense.

Why is my ice sticking together?

Ice starts to stick together when there’s excess moisture between the ice cubes that freezes over. One way you can get rid of this is to wrap the bucket in the paper. The trick here’s that paper has tiny pores that absorb extra moisture. And it’s this moisture that refreezes and makes two ice cubes stick.

How do you make ice stick together?

To make the ice cubes stick together, generously dip one ice cube in salt, wait a second, and then place it on top of another ice cube. When you’re done, (or at any point in the middle!), add drops of liquid watercolors for an even more magical look!

What melts ice faster salt or sugar?

Salt will always melt ice quicker than both of them. This is because in the same amount or volume, there are more molecules of salt than sugar or baking soda due to the chemical make-up.

Why does ice stick to a string with salt?

Because saltwater freezes at a lower temperature than pure water adding the salt makes some ice melt and absorb heat in the process. The area just around it thereby cools and freezes water molecules to the ice cube, also freezing the string on.

Why does ice stick to the tray?

Ice cubes break into pieces because the plastic trays become coated with hard-water mineral deposits (calcium carbonate) that settle into nicks and scratches in the cube compartments and build up over time. Water clings to these deposits as it freezes.

How do you make ice cubes easier?

A good trick is to fill up the Ziploc up quarter-way and then zip it up and lay it flat on the floor of the freezer. This will create a layer of ice that’s medium in thickness and easy to break up into smaller pieces. The major downside that comes with Ziploc bags is that your ice will be shapeless, for the most part.

What is the easiest way to remove ice cubes from trays?

To remove easily the ice cubes from the ice cube tray you just need to pour a glass of water on the back. After this the cubes will come away immediately.
