Does your slush machine need fixing? These common problems with slush machines can leave them looking a little worse for wear... but don't fear! There may be a cheap and easy solution to repair your slush machine problems that you can do yourself. So you can get back to selling slush to all your thirsty customers as quickly as possible.
Before you start any maintenance on your machine, make sure it is switched off at the power switches and plug socket to avoid injury or electrocution.
All switched off? Great! Then let's take a look...
Slush Machine Leaking
If your machine is leaking, the first step is to work out where the leak is coming from. This will determine how to fix the leak.
Let’s dive in to some slush machine troubleshooting…
Tap Leaking
If the leak is coming from the tap, on your slush machine, the cause is usually a stiff tap or damaged seals. First try lubricating the tap at the rotation point, you may need to give the tap a couple of turns to get the lubricant into the mechanism.
If this doesn’t solve your leakage, check the seals within the tap head and check they are in the right place and not torn. If the seal is broken, you can order a spare here.
Overflow Outlet Leaking
If your overflow outlet is leaking clear liquid, this is nothing to worry about. This is simply condensation from the outside of the machine being collected and disposed of.
However, if the liquid is the same colour as your slush, there is likely to be damage inside your machine. Firstly, check the seal at the back of each tank is fitted properly and is still intact.
If your seal looks in good shape, check the shaft and its seal for wear and tear. Usually, it will be the seal that’s causing the leak which will simply need replacing. However, it is possible that the shaft itself is worn down, which is more difficult to do at home so you may require some additional help.
Why Is My Slush Machine Not Freezing?
A slush machine usually won’t freeze because of the wrong syrup ratio, poor airflow, or a dirty condenser.
1. Incorrect syrup ratio
The most common cause is mixing the syrup incorrectly. A slush machine won’t freeze if the sugar content is too low or too high. For our syrups, use a 6:1 water-to-syrup ratio (six cups of water to one cup of syrup). This ensures the right sugar balance for freezing.
2. Airflow problems
If your ratio is correct but the slush still isn’t freezing, check the airflow. Slush machines need at least 40 cm of clearance around the unit, especially near the fan. Blocked airflow prevents proper cooling.
3. Dirty condenser
A blocked condenser is another common reason a slush machine won’t freeze. Dust buildup stops the machine from cooling properly. Clean the condenser regularly with a brush to keep airflow clear and freezing consistent.
Overheating
Machine overheating is also caused by a restricted airflow.
If your slush machine is too hot, make sure there is at least 40cm of clearance around the machine and that the condenser filter is cleaned as above.
Slush Machine is Freezing on the Outside
If your slush machine is frozen on the outside of the tank, the slush ratio may not have enough water. To rectify this, switch off your slush machine and let the slush defrost, remove the mixture from the tank and refill with a slush mixture with a ratio of 6:1.
Alternatively, freezing could be due to the machine being left on for too long. Make sure you turn off the machine while it’s not being used and allow the slush to fully defrost before switching back on. This can be done overnight if you prefer.
