Hoshizaki Ice Machine Water Keeps Running

If you have a Hoshizaki ice machine, it’s likely that you’ve had to deal with the problem of it running too much. The water keeps running and you’re left with an empty ice machine. It can be frustrating when this happens, especially if you don’t want to give up on your favorite drinks just yet.

Hoshizaki ice makers are known for their reliability and long life.  However, just like other appliances, something could go wrong. If you notice your ice machine is running more than usual, it’s worth checking to see if there’s anything you can do to stop it.

Why Water Keeps Running in Hoshizaki Ice Machine

There are many possible reasons why this ice machine might malfunction and have water running continuously. From small issues like unleveled placement to potentially major ones like valve issues here are some reasons why your Hoshizaki Ice Machine water keeps running. We also discuss what you can do about it.

Unleveled Placement

One of the most common reasons for your Hoshizaki Ice Machine water to keep running is that it is not level. The water needs to be leveled in order for the ice maker to function properly.

If the water is not level, there will be a slight bulge on one side and a slight dip on the other, which can cause the ice maker to malfunction or stop working altogether. Make sure that you have leveled out your ice maker by adjusting its height with a spirit level.

Improper Installation

If you’ve bought a new unit but it has not been installed properly, it could cause your ice machine to keep running water. Water will flow out of your Hoshizaki ice machine at first, but if you have properly installed it, there should be no leaks in the unit. 

As such, you want to check pipe connections and freeze coils. If there are no leaks and all pipes are tight, then check the water pump. The water pump should be placed inside the freezer compartment rather than out in the open air.

Loose Connections

Loose connections are the most common reason why your ice machine keeps running water. You may experience this problem when the water runs continuously without stopping even after turning off the power to your ice machine. 

This happens because the water is still flowing through the hose and into the ice maker, instead of being collected by the ice maker. To fix this issue, make sure that all hoses are connected properly with clamps.

Pierced Water Supply

A common issue with Hoshizaki ice machines is the pierced water supply. When the water supply is pierced, it can result in a clogged dispenser, which will cause the machine to stop working. The solution to this problem is to simply remove and clean out the pierced area on your ice machine. 

You can do this easily by unclogging it with a spoon or something similar. Once you have cleaned out the hole, put some rubber bands around it and place them over your ice machine so that they hold it closed until you can replace it with a new one.

Unaligned Fill and Valve

When your Hoshizaki Ice Machine water keeps running water, it’s usually because the fill and valve are not aligned correctly.

When you open the ice maker’s lid, the water will run out of the bottom of the ice maker. The fill tube should be perfectly vertical and pointing straight up from the bottom of the ice maker. If it isn’t, then it can cause problems down the road.

The valve is responsible for controlling how much water comes through into your ice maker at any given time. If it’s not aligned properly, then there won’t be enough water coming in and out of your ice machine at all times, causing it to stop working properly.

A Build-up of Ice

Ice buildup is the most common reason for water to run out of your ice machine. The most common cause of this problem is due to a clogged ice bin, which leads to a clogged line. This can be caused by dust or hair that has gotten into the ice machine and blocked the water flow into the ice bin. Another cause could be an overflow drain that’s not working properly, which would allow more water to flow out than expected.

How to Adjust The Ice Size on A Hoshizaki Ice Machine

If you are not impressed by the ice size that your Hoshizaki machine is producing, you want to adjust it.

Step 1

The first thing you want to do is locate the valve on top of the water pump and remove the screws securing it. This will give you access to the internal parts of the machine.

Step 2

Once you open the valve, you will see a rubber seal and a spring. If they are covered in calcium, you want to clean them up.

Step 3

Next, you want to put the seal and spring back to the machine. However, if your rubber seal is worn out or damaged, you will need to replace it. Ensure that it is aligned properly to avoid leaking.

Step 4

Put the screws back on and wait for about forty minutes. You can now test your ice maker and you will realize that the cubes are thicker.

How do you increase ice thickness on a Hoshizaki?

These machines feature a float switch that controls ice thickness. All you have to do is slide this switch down to get thicker ice.

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

The switch regulates the machine especially when it’s time to stop freezing water. Moreover, this switch monitors the amount of water in the machine’s reservoir as it fills.

Why is my Hoshizaki ice machine not making enough ice?

The reason could be as simple as a dirty valve, water filter, air, filter, or evaporator. Usually, dirt buildup causes low ice production. That is why it is necessary to deep clean your ice maker regularly.

How long does it take for a Hoshizaki ice machine to make a batch of ice?

For a Hoshizaki ice machine to perform as expected, it requires the right operating conditions. It should produce 592 lbs. with an air temperature of 70 degrees and a water temperature of 50 degrees within 24 hours.
