Overview
Drink machines rely on refrigeration performance, column alignment, and strong door seals. Electrical or cooling issues often present as temperature drift. Clear stuck products in stacks.
Diagnostics
- Check door gasket seal and condenser cleanliness.
- Verify temperature sensor readings and controller setpoints.
- Inspect stack/column alignment for mis-vends.
Resolution steps
- Clean condenser coils and ensure airflow clearance.
- Replace faulty temp probes or relays.
- Align columns and adjust shims for product fit.
Preventive maintenance
- Vacuum coils monthly in dusty locations.
- Log temperature readings by location.
- Rotate stock to reduce heat load.
