Could the drain pump be clogged?
Put a load of laundry in the machine filled up with water then nothing the 'green senser light is on I drained it manually it drained out very slowly so I was wondering if what's causing the machine not to start is it is plugged it drained all the water except a couple gallons I did the test on it and it did everything but left a couple gallons of water in it
