This depends on site conditions and usage.

• Until a routine is established, we would recommend checking the Pre-Filters, Post Carbon and TDS of membrane weekly.

PLEASE TURN OFF POWER TO YOUR MACHINE. Then, select instructions below for your UV:

10 inch UV bulb replacement (View Here)

If you have a 900, 950 or 1100 interface in your machine, TURN OFF POWER to the machine and then click instructions below: (View Here)

• Is the power on?
• Does the machine accept either bills or coins? 
  • If the machine will accept one type of payment but not the other, the problem will be with the unit that is not accepting the payment
  • Or does the machine not accept either?
• If the machine is not accepting any form of payment this means the machine is in some sort of failure mode
  • First item to check 
    • Is to make sure the UV light is on. To check this each UV control unit will have a LED on it, if the LED is on then the UV lamp is on. If there is no LED then the UV lamp needs replaced
  • Second item to check 
    • Is to make sure the holding tank is full of water & the tank empty float is connected properly & does not have broken or corroded wires
      • Check the tank empty float by unplugging from cabinet harness and using a multi meter to check continuity on the tank empty float wires. If the tank is full the float should give you good continuity reading
  • Third item to check 
    • Is if your Emergency Shut Off (ESO) float is connected properly & does not have broken or corroded wires
      • Check ESO float by unplugging from cabinet harness and using a multi meter to check continuity on the tank empty float wires. If the tank is full the float should give you good continuity reading

• Check your price settings on the interface to ensure they are as you think they should be
• Can you manually dispense coins from the coin changer by pushing the coin tube dispense button for each tube?
  • If yes
    • Double check price settings
  • If not
    • If no tube will dispense coins there might be a power issue with your unit
    • If some tube will dispense coins and others will not 
      • There might be a stuck coin or debris in the dispenser
      • Your interface might need the upgraded external power supply that is screwed to the face plate of the interface case
      • The pay out tube for that particular coin might be stuck or bad

• When a machine taken money and does not dispense this mainly means 1 thing, the machine is in Flow Sensor Failure (FSF)
  • Is the Pump fuse (F2) on the back of the 2000/2500 Controller still good?
    • If no then replace with a 3AMP fast acting fuse
  • Does your machine work properly for several gallons or a day once the power at the machine has been cycled off & on?
    • This is a typical sign that the vend pump needs to be replaced
      • Our ASI vend pumps typically last for 30,000 – 40,000 gallons dispensed. 
      • We recommend writing the date as well as the gallon counter reading from the 2000/2500 controller on a blue piece of painters tape in sharpie then placing that piece of tape on the vend pump to keep track of that vend pumps out put.
• Vend pump is not the issue
  • When the vend pump has been determined not to be the issue
    • First check the wires going to and from the flow sensor on top of the vend compartment & the 6 pin connector under the controller with the Red, Black, Clear, Violet & Violet/White stripe wires
      • Any cracked wire
      • Any water corrosion
      • Any broken wires
      • Any pins pushed out the back of the connector
    • Second item to check
      • Turn your power ON
        • Set your multi meter to DC Volts and check the RED & BLACK wires going to the flow sensor have 4.5-5 VDC with the POWER ON
      • Turn your power OFF
        • Set your multi meter to continuity and check the WHITE wire from the flow sensor all the way to the back of the 2000/2500 Controller
    • Third item that could be the issue is the flow sensor its self
      • This is a non-serviceable item & can only be replaced
