How Vending Machines Work

Step 1: Selection

The first thing you do when you get a vending machine is pick one. You walk up to the machine, look at the options, then press the button for what you want. All of a sudden, a bunch of different machines start working.

Step 2: Inventory Management

Once you have chosen your item, the machine will check its inventory to make sure it is still available. Most modern vending machines have sensors that detect the presence of each item and the quantity of each item. If the item you have chosen is still available, the machine will proceed with the next step; however, if it is sold out or not available, you will be asked to select an alternative item.

Step 3: Payment

Next, it is time to pay. Vending machines provide a variety of payment methods, including coins, invoices, credit cards, and mobile payments. The machine will verify your payment to ensure it is the correct amount for the item you have selected.

Step 4: Dispensing

Once your payment has been accepted, the machine will prepare to deliver your item to the collection point. A robotic arm (or conveyor) will retrieve the item from its slot or compartment, and the item will then be delivered to the collection point, where you can pick it up.

Step 5: Changes and Receipts

When you pay with cash and you owe change, the machine will figure out how much you owe and give you the change. Some machines even give you receipts so you can keep track of your change. Once you’ve completed your transaction, you’re ready to enjoy your snack or drink of choice!

How to fix a Vending Machine?

1. Safety First

First, make sure your machine is as safe as possible. Before attempting any repairs, make sure to unplug the machine and disconnect it from any power sources. You’ll also want to make sure you’re wearing the right protective gear, like gloves or safety goggles, so you don’t get hurt.

2. What’s the problem?

Start by determining the exact problem you’re having with your Vending Machine. Is it power failure? Is the coin mechanism jammed? Is the product stuck in delivery area? Knowing what’s causing your problem will help you find the right solution.

3. Refer to the Manufacturer's manual.

It is important to consult the manufacturer’s manual. This manual will give you important information about your machine’s parts, wiring diagrams and troubleshooting methods specific to your model. Always follow manufacturer’s instructions for safe and effective repairs.

4. Power Failure

Make sure your machine is plugged into a working electrical outlet. Look for signs of damage on the power cord and replace it. If power failure persists, it could be an internal wiring issue or an issue with the machine’s power supply, which requires professional help.

5. How to Fix a Jammed Coin Mechanism

Open the coin door of your vending machine and use a flashlight to check for obstructions and debris in the coin path. Carefully remove any foreign objects from the coin path so that you don’t damage delicate components. Use a silicone based lubricant to lubricate the moving parts and prevent future jams.

6. Product Stuck

When a product becomes stuck in a vending machine, it is important to open the product delivery area and remove the obstruction. Care should be taken to ensure that the dispensing mechanism is not damaged. Once the product has been removed, the machine should be tested by dispensing another product to confirm that the issue is resolved. If the issue continues, it may be indicative of a mechanical or electrical issue that requires professional assistance. If this is not possible, it is recommended to contact a qualified technician with experience in refrigeration repair.

7. Vending machine cooling issues

When using a vending machine with a cooling system, it is essential to maintain the product temperature to ensure optimal freshness. To begin, check the thermostat to ensure that it is set to the correct temperature and functioning correctly. Additionally, clean the condenser coils to improve cooling efficiency.

8. Faulty Display or Buttons

To solve the display or buttons issue, clean the control panel surface with a cloth and mild cleaning solution. In some cases, dirt or debris can interfere with the functionality of the components. If cleaning doesn’t solve the issue, check for loose button connections and wiring or damage. If the problem persists, you may need to replace the faulty buttons or display module.

9. Faulty apps

Vending machines use different apps to process orders, show content, and do many other things. If one of these background applications starts to malfunction, the entire vending machine may appear to be broken. You’ll need remote technical support to locate the issue remotely. You can then update the program to correct the flaws or replace the program with a new one if the issue persists.

10. Error in Authentication

If an automated vending machine’s authentication process takes too long, you’ll see error messages like “connection timeout”. Card reader issues are sometimes the result of an error with the bank’s end of things. You can’t do anything about it except wait. If you’re not sure if the bank is at fault, try resetting the card readers.

11. A Faulty Evaporator motor fan

If the fan of your vending machine is whining, it may be time to replace the evaporator motor. Your control board is usually connected to the evaporator motor, and it should be operating at the specified voltage. An ohmmeter can be used to check whether the fan’s motor is turning. If the fan is turning, it may be making too much noise or is out of balance.

Tools You'll Need

To efficiently fix a vending machine, it's essential to have a few tools at hand. Here are some tools that can be useful during the troubleshooting process:

? Screwdriver set (both flathead and Phillips)

? Needle-nose pliers

? Multimeter

? Flashlight

? Cleaning supplies (such as an air duster and lint-free cloth)

? Spare fuses and electrical tape

With these tools in your arsenal, you'll be well prepared for most vending machine repair tasks.

What if the problem persists?

Get in touch with your banking partners.

If you are having issues with card readers on your machine, contact your bank to see if there are connectivity issues. If your machine suddenly requires cash-only payments and stops accepting cards, then there is likely a connection issue. Make sure you have also paid your bank fees on time. Otherwise, your bank will cut off the connection to your machine and it won’t be able to accept card payments.

Request Technical support

Look in the owner’s manual for customer care details, whether it’s for your card reader or for the machine itself. You should find a phone number or an email address to contact for more information. You can also contact a local vending machine repair professional to investigate an issue and make any necessary repairs.

Run regular maintenance.

In order to ensure the longevity of your vending machine, it is essential to regularly clean it. This can be done by regularly emptying the stock and replacing it with fresh stock. Additionally, it is recommended to use compressed air to remove any debris and dust that may have accumulated on the coils or trays. Regularly cleaning the machine is the most effective way to prevent any errors from being made in the future when reading currency. This is because currency can introduce a large amount of fat and dust into the coin mechanisms and bill acceptors.

Do you require a coin refill?

If the machine does not give change, it is likely to be broken. To determine if there are sufficient coins to complete transactions, take a look inside the machine. A short coin refill may be the answer to any of your problems.

Clean up and remove any dust or dirt that has built up while you are in the machine. If the sensor of an older machine has dirt, it is highly likely to cause problems.

Conclusion

Figuring out how to fix a vending machine can be intimidating, but with the right tools and knowledge, it's much easier. Knowing the basics, how to troubleshoot common issues, and taking preventative steps can help you save money, time, and stress.

Keep in mind that some repairs may need to be done by a professional. If you don't know what to do or don't feel comfortable with any repair, it's a good idea to get in touch with a certified technician. They have the know-how and experience to take care of complicated repairs and make sure your machine runs smoothly.
