How to Maintain a Cooking Oil ATM: Cleaning, Calibration and Common Fixes
Quick answer: Wipe the nozzle and drip tray daily, check the dispensed volume against a measuring jug every week, and clean the tank whenever you change oil batches. Keep the machine out of direct sun and the lid closed. Most problems (slow flow, drips, wrong amounts) come from dirty nozzles, thick cold oil or calibration drift.
Key facts
  • Daily: wipe nozzle and drip tray
  • Weekly: check volume with a measuring jug and recalibrate if needed
  • Clean the tank between oil batches
  • Keep out of sun and heat; keep the lid closed

Frequently asked questions

How often should I clean a cooking oil ATM?

Wipe the nozzle daily and clean the tank every time you change oil batches.

Why is my oil ATM dispensing less?

Usually calibration drift or thick cold oil; check with a measuring jug and recalibrate.

Can I leave the machine in the sun?

No. Heat and light degrade oil and stress the machine; keep it shaded.
