Ingredient Not Dispensing Diagnostic
This process traces the entire path of the powdered ingredient, starting from the storage canister, through the dispensing auger, and out the chute, to pinpoint why the powder is not reaching the beverage.
- Motor buzzing or grinding but auger not turning: Stop vend cycle. Possible mechanical jam or motor failure. Do not force. Escalate to technician.
- If the motor is buzzing but the auger does not turn, do not force it; this mechanical issue requires a qualified technician to safely clear the jam or diagnose motor failure.
