Troubleshooting Tips

#9 - Modular Gilbarco, error code 31 or 35

Flash Price/003.1 or Flash Price/003.5

The following procedure should always be observed when changing anything on a Gilbarco Modular Pump

Step 1. - Turn off Power to the head, either with a Circuit Breaker, or by pulling the bottom Fuse on the Power Supply (do not pull the top one as it is the Battery Fuse and will cause your problem). The displays should now only have the decimal places lit (if they are not the Battery was no good or the top Fuse was blown and you can quit blaming yourself).

Step 2. - If they did stay lit, turn off the Battery. To do this press "CLEAR" and "ENTER" on the pump keypad. The decimal places on the displays should now go out.

Step 3. - Now unplug and change anything you have to change.

If the Battery was dead or the Fuse was blown (as indicated in Step 1) or had been disconnected before powering the unit down, you will get error code 31 or 35 after you power the unit up.

Confirm all connections and Re-Apply power to the Pump
