How do you check pump on little green machine?

To check the pump on a Little Green Machine, first ensure the unit is unplugged and empty. Inspect the pump for any visible signs of damage or blockage, such as debris or clogs in the hoses. You can also run a test by filling the clean water tank and turning the machine on to see if water is being drawn through the system. If there are issues with water flow, it may be necessary to clean or replace the pump.
