Cleaning Schedule
- Daily: nozzle, drip tray and outside surfaces.
- Between batches / when empty: wash and sanitise the tank and lines (see how to clean a milk ATM).
- Weekly: condenser area dust, floor and walls.
Cash, M-Pesa and Stock Reconciliation
Litres received − litres left in the tank = litres sold. Litres sold × price should match cash plus M-Pesa (allowing for any free tasting or spills you record). A daily gap means a calibration problem, spills or theft; investigate the same day. See M-Pesa vs coin payment for payment options.
Power Outages
- Keep the lid closed; a full, cold tank holds temperature for some time.
- Use backup power for long outages (see backup power).
- If milk warms, test before selling; never sell doubtful milk.
When Something Goes Wrong
Dispensing inaccurate amounts, not cooling, or payment errors: see milk ATM troubleshooting and call your supplier.
