Where's my serial number?

On machines: The serial number (shown as "S/N") is located on the white label near the model number. See image below as an example. The label is usually located at the lower back or bottom of the machine (for Lift-Off models - remove Lift-Off pod to locate), or behind the cleaning tanks.

On cleaning formulas: cleaning formulas do not contain serial numbers. Instead, please enter the full number from the UPC code. Look for it on the back of the bottle or can, near the bottom.
