Why does my Wayne Vista computer reset but valves do not open?
- R
  robertstrongAug 21, 2025
  Several factors can cause this issue. First, check the F1 fuse on the Solenoid drive board and replace it if necessary. If the fuse is fine, the solenoid drive board might be defective; check for 110 VAC output from it and replace the board if there's no output. Also, the actuator coil could be defective, so check the coils for continuity and replace any with an open circuit. A defective or stuck actuator or diaphragm can also be the cause; inspect both valves and replace or rebuild them as needed. Finally, the computer assembly itself might be defective and require replacement.

What to do if my Wayne Vista sale display and unit price displays are blank?
- S
  Sherri CarrAug 23, 2025
  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?
- J
  Jacob SanchezAug 25, 2025
  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?
- J
  James WilliamsAug 26, 2025
  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?
- S
  Samuel GutierrezAug 29, 2025
  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 does fault code 51 mean on my Wayne Dispenser?
- L
  Lawrence AndersonAug 30, 2025
  Fault code 51 indicates a flow restriction on one end grade. Observe the blend valve while dispensing to see if it moves towards “HI OFF” or “LO OFF”, indicating the opposite grade has the restriction. Check all valves and flow tubes for obstructions, and clean the strainer and change the filter. Also, check the linkage from the blend motor to the blend valve for free movement and any interference. A leak between chambers in the blend valve can also cause this; replace the “O”-ring between chambers or the entire blend valve. Other potential causes include a defective solenoid drive board, a defective F2 fuse on the computer, a defective computer, or a defective blend motor. Replace any defective components as necessary.

Why is my Wayne Vista Dispenser sale display ON, but the unit won't respond to any function switches?
- B
  Brenda HendersonSep 1, 2025
  This issue could stem from several causes. Defective switches are a common culprit; check for +5VDC off and zero volts on. Replace the switch if the voltage is constant at either 5 or 0. A blown fuse on the lighted Cash/Credit Interface board could also be the problem; check F1 on the interface board and replace the board if the fuse is blown. Defective wiring to the switches is another possibility, so check all wiring to the function switches. Additionally, defective switch interface circuitry on the Cash/Credit interface board or a defective computer assembly could be the cause. Replace the Cash/Credit Interface board or the computer assembly as needed.

What does fault code 03 mean on Wayne Vista?
- T
  Thomas JensenSep 3, 2025
  Fault code 03 can be caused by several issues. A shorted solid-state relay on the solenoid drive board is a potential cause; check for 110VAC output to the valve(s) with the handle off. If 110VAC is present, replace the solenoid drive board. Debris in the diaphragm valve or actuator can also trigger this code, so check and clean all valves. Other possible causes include a defective diaphragm valve (install a diaphragm service kit), a defective actuator (replace the actuator), or a defective computer (replace the computer).

How to troubleshoot fault code 01 on a Wayne Vista?
- P
  paulfrancisSep 4, 2025
  This fault code may be due to a defective push-to-start or cash/credit switch. Check the switch(es) and replace them as necessary. Defective switch wiring could also be the cause, so check all wiring from the suspect switch to the lighted cash/credit interface board and repair or replace the wiring as needed. If the switches and wiring are fine, the lighted cash/credit interface board itself might be defective, requiring replacement. Finally, a defective computer could also trigger this code, so consider replacing the computer if other solutions don't work.

What causes fault codes 14, 15 or 16 on a Wayne Dispenser?
- R
  Randall RiceSep 5, 2025
  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.
