What does fault code 06 mean on a Wayne Vista Dispenser?
This fault code suggests that the solenoid drive board has a defective solid-state relay, so replace the solenoid drive board. Alternatively, the computer might be holding the solid-state relay on, in which case, replace the computer.
What to do if my Wayne Vista sale display and unit price displays are blank?
This issue may arise due to several reasons. First, verify that the computer is receiving power by checking the control power circuit breaker and testing for AC between pins 1 and 2 of the J3 connector. If no AC is present, check the J-box; if still absent, the problem lies within the site wiring. However, if 110 VAC is present in the J-box, the issue is within the dispenser's internal wiring. Also, inspect F1 and F3 fuses on the computer and replace them if needed. If power is not the issue, the display board or the computer itself might be defective, requiring replacement.
Why is my Wayne Dispenser computer resetting but the submersible pump isn't turning on?
This can occur for several reasons. Start by checking the F1 fuse on the solenoid drive board, replacing it if necessary, as the solenoid drive board might not be turning on the relay. If the fuse is fine, the solenoid drive board itself might be defective; check for 110 VAC output from the board and replace it if there's no output. A defective relay could also be the cause, so try replacing it. Check also the station wiring. If 110 VAC is present at the drive board and in the dispenser junction box, but not at the relay panel, the problem is in the station wiring, so correct it. Lastly, the computer assembly might be defective, requiring replacement.
What to do if Wayne Dispenser unit price is displaying .0.000?
This can happen for a few reasons. Check that the control system unit price isn't set at 0.000; if it is, set the correct unit price. If a control system is connected, but the unit price is still not set at the dispenser, set the correct price using the price jog switch. If data was corrupted and then cleared by the computer, reset prices and/or option programming; if the problem reoccurs, replace the computer. Also, if a control system is not connected, ensure the fueling point is set. If none of these steps work, the computer may be defective and need replacement.
How to fix a Wayne Vista when the computer will not reset?
Several issues can prevent the computer from resetting. First, ensure that the unit prices are not 0.00. If they are, refer to the instructions for setting the unit price. Also, check if the dispenser computer is authorized. If a control system is installed, refer to its operation manual. For a standalone dispenser, check the Self Serve/Attend switch. Additionally, inspect the nozzle switch for defects or misadjustments and adjust or replace it as needed. A defective push-to-start switch or switch interface circuitry could also be the problem; check the push-to-start switch and troubleshoot the switch interface circuitry. Finally, the computer itself might be defective, requiring replacement.
What causes fault codes 05 or 20 on a Wayne Vista?
These fault codes can be triggered by several issues related to the pulser disc. Check for a cracked or broken disc and replace it if necessary. Ensure there is no dirt blocking the opening on the pulser disc and clean it if needed. Remove any dust from the housing and photocoupler, and adjust the disc to prevent rubbing. Verify that the disc tension is correct by adjusting or shimming the wave washers on the pulser shaft assembly. Misalignment between the pulser drive shaft and the coupling gear on the meter can also cause this, so ensure the drive shaft is aligned in the center of the coupling gear by loosening the mounting bolts on the pulser housing and repositioning it. A defective photocoupler, air in the system causing hydraulic shock, a loose plug or wire connection, a defective so...
What does fault code 04 mean on a Wayne Vista Dispenser?
This code means the computer found a defective ROM chip during a self-test. Clear the error, and if the problem reoccurs, replace the computer.
What does fault code 11 mean on a Wayne Dispenser?
This code indicates that the computer found scrambled data in option programming. Check all option programming and set option 99 to 03 to clear the error.
Why is my Wayne Dispenser sale display ON, but the unit won't respond to an individual function switch?
This problem may arise from a defective switch. Check for +5VDC off; zero volts on, replace switch if voltage is constant at either 5 or 0. Another potential cause is defective wiring to the switch, so check all wiring to the function switch that is not working.
What causes fault codes 14, 15 or 16 on a Wayne Dispenser?
These fault codes can arise from several issues. Debris holding the diaphragm or actuator open is a common cause, so check and clean all valves. A defective diaphragm or actuator can also be responsible; install a diaphragm repair kit or replace the actuator as needed. If the dispenser is a V390/U model (Single Hose MGD), check the restrictor plates on the meter supports of the unselected product and clean or replace them as needed. A shorted relay on the solenoid drive board can also trigger these codes; check for AC output with the dispenser off, and if AC is present (the same voltage as AC input), replace the solenoid drive board. Finally, a defective computer could be the cause.
