Understanding Haha error codes and LEDs

Error codes and LED states point to specific subsystems.

• Record the exact code or LED pattern.
• Check the portal for matching device alerts.
• Confirm whether the unit is still processing sales.

• Reboot the unit and recheck status.
• Inspect power and network connections.
• Address the specific subsystem indicated by the code.

• Keep a quick reference sheet on your route.
• Track repeated codes by location.
• Perform routine checks to prevent recurring faults.

• Error code persists after reboot.
• Unit remains offline or in safe mode.

• Confirm all steps are documented so the next technician can reproduce the results.
• Capture before/after metrics (errors cleared, sales restored, or uptime improved).
• Review machine, reader, or route settings to ensure they match location standards.

• Skipping a controlled test leads to false positives.
• Updating hardware without documenting configuration changes.
• Forgetting to verify payout, refund, or reconciliation data after changes.

• Run a final test with known-good inputs.
• Log the outcome with date, time, and device identifiers.
• Schedule a follow-up check if the location has high traffic or seasonal demand.

• Document changes with time, machine ID, and location name.
• Verify settings, pricing, and service modes after each fix.
• Capture before/after results to confirm resolution.

• Test with known-good inputs and controlled conditions.
• Validate telemetry, alerts, and payment logs where applicable.
• Confirm location expectations and update the site contact.

• Configuration drift after firmware or component swaps.
• Inconsistent power or network conditions at the location.
• Gaps in preventive maintenance routines.

• Monitor for 7 days and note any repeat errors.
• Schedule follow-up if the site is high-traffic.
• Escalate with full logs and photos if issues repeat.

• Validate camera calibration and lighting conditions.
• Confirm planogram and SKU mapping are accurate.

• Verify load accuracy to reduce mischarges.
