The extra opens back up the gate queue and clog the tunnel. ## Cause The gate queue has gotten **out of sync**. The most common reason is that an operator is **manually opening the gate for members** at the entrance. Each manual open adds a car to the gate queue that never gets matched and cleared, so the queue keeps growing and the gate keeps firing. ## How to fix it from the tunnel tablet On the tunnel tablet, tap the **Coordinator** link in the top left to return to the main menu. From the menu, tap **Gate Control**. Navigate to Gate Control You'll see Gate 1, Gate 2, and Gate 3 with cars stacked beneath them (license plate + photo). The gate with several cars queued under it is the one that's out of sync. For each stacked car, tap **Move to Wash Queue**. This moves the cars out of the gate queue and into the wash queue, clearing the backup so the gate stops firing on its own. Manually move vehicles to the Wash Queue These are stale, unmatched entries, so once they're in the wash queue you can delete them from there. If the banner **"Waiting for close signal…"** is showing across the top, tap **Clear Merge Loop** to reset it. ## If the gate is still misbehaving As a reset, **restart the web service** to flush the queue. This clears the backup immediately — but if the underlying behavior continues, the queue will fill up again, so treat it as a quick fix rather than the cure. ## Prevention **Stop manually opening the gate for members.** Manual opens are the usual root cause. Let the system match members through the normal flow instead of opening the gate by hand. If a member needs to be let through, move them through the wash queue rather than manually triggering the gate. ## When to escalate If the queue keeps backing up after you've drained it and stopped manual opens, contact FlexWash support.
