Machine Technical Issues

Spiral motor does not rotate

Check motor wiring, vend switch alignment, and selection pricing settings.

Updated Feb 9, 2026

Overview

Confirm the selection is enabled in the pricing menu and that the price is not set to zero or “disabled.” Inspect the motor harness for bent pins and test the motor by swapping it with a known-good selection.

Check the vend switch or home position sensor. If the switch is misaligned, the controller may think the motor already completed a cycle. Reset the motor position by manually aligning the spiral to the home detent.

If the motor fails under direct test, replace the motor assembly. If it runs when swapped, the issue is in the controller output or wiring harness for that slot.

Diagnostic checklist

  • Confirm the selection shows “ready” in the service menu.
  • Inspect the spiral for product jams or misalignment.
  • Test the motor at the controller output with a meter if available.

Preventive maintenance

  • Keep spirals aligned to the home position after every refill.
  • Avoid overfilling, which increases motor load and stalls.
  • Replace worn motor couplers before they strip.

When to escalate

  • Motor stalls under no load.
  • Multiple selections fail on the same controller board.
  • Wiring harness shows heat damage or brittle insulation.

Expanded guidance

  • 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.

Common pitfalls

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

Next-step checklist

  • 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.

Additional details

Operational notes

  • 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.

Field checklist

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

Common root causes

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

Next steps

  • 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.

Technical deep dive

Diagnostics

  • Inspect harness integrity, connectors, and power supply stability.
  • Review error codes against the OEM manual before swapping parts.
  • Compare with a known-good component to isolate the fault.

Preventive actions

  • Clean sensors monthly and replace wear parts on schedule.
  • Log firmware versions and configuration baselines.
