Vending Machine Maintenance Routine

Anytime a large purchase is made, such as a vending machine, there is a definite amount of care and maintenance that goes along with it. Just like purchasing a home or a vehicle, vending machines are an investment and should be treated as such. Improper usage and neglect will cause a decline in the productivity of a machine and will fundamentally lead to a loss of revenue.

There are number of things a vending machine business owner should regard as when developing a vending maintenance schedule in order to keep their machine running successfully. Our own special technician here at the Discount Vending Store has taken the time to list some of the most important habits for machine conservation.

 

Refrigeration Deck

Clean the refrigeration air intake coils every 2-4 months. The condenser is normally located at the very bottom of the machine and accessed from the front, however some models it is accessed from the back of the machine. First, you will need to take out the protective metal kick-plate that is easily identified by the air intake slits or holes. This plate usually just lifts off but may be attached to the unit with screws. Second, you can use a brush to remove any heavy accumulation of lint. Afterwards, it may be necessary to use compressed air to clear fine dirt/dust particles from the condenser itself. After cleaning is complete, you can remount the kick-plate to the vending machine.

 

Bill Validator

The Bill Validator should be cleaned every 30 to 60 days, depending on use. Always remove power to the vending machine before cleaning. Start by removing the cash tray on the back of the unit. Clean the tray with a clean dry cloth. Next, remove the sensor tray, located above or below the cash box. This will normally pull out by depressing the two tabs on the sides of the tray. Clean the sensor tray with a clean dry cloth. If it is extremely dirty, you can dip the cloth into soapy water, wring out completely until damp and clean the tray. Always dry the tray when complete.

 

Surge Protector

Always plug your machine into a surge protector and not just a power strip!!! Most surge protectors will have a resettable test button or switch. Test the protector every so often to make sure it is working properly. If your protector has a test button, press it to make sure it trips. If it has a switch, turn the switch off to make sure it cuts power to the vending machine. When testing either of these two cases, if power to the vending machine is not cut, replace the surge protector.

 

Coin Units

The Coin unit tubes should normally be filled 2/3 full for best operation. The Coin units should be cleaned every 30 to 60 days, depending on use. Always remove power to the vending machine before cleaning.  Clean the coin inlet with a clean dry cloth. If it is extremely dirty, you can dip the cloth into soapy water, wring out completely until damp and clean the tray. Always dry the tray when complete. Clean the coin run on mechanism side and door side. Always check for broken or missing parts while cleaning.

 

Snack Vending Mechanism

Check for proper drink/snack vending operation every time you load a new product or every 60 to 90 days. Enter the machines service mode and perform a motor test to vend your product to ensure there are no issues. Normally there are little to no issues with vending snacks. Drinks may have vending problems due to bottle/can size and the total weight associated with the drinks when fully loaded. Always test vend with 1 to 3 bottles/cans before fully loading the machine to ensure no issues. If drinks don’t vend properly, check the delivery mechanism for binding, use of proper shim, product loaded properly, sold out sensors, or motor issues such as failure or stripped gears.

  1. I’ve been using the vending machines at work and I began to wonder how they were maintained. I appreciate what you said about how often the separate parts get cleaned such as the bill validator and the coin units. I think you made a very precise list of things to consider when taking care of the machine.

    • i was thinking that in the future there will be how to videos in maintaining the machines which will be more helpful and more transparent for everyone to know the inner workings of the vending machine
