OK! I had to do some work on this off-grid washing machine. I had to get a second bucket and drill some holes into it and I drilled a few holes into the plunger. Now it works a lot better and the water can be drained out a lot easier. Drain it out of the bucket into the other bucket, pour that out , put clean water into it and repeat. Do it until the water is coming out “clean” – no soap. 

Going to try it out in a couple of days and see how it works. Might need to drill bigger holes.
