I am at a loss with this thing. Bout ready to throw it in the trash. Yesterday I came on to find out why my manual WC wasn't working. Got it going and it went all day. This morning I set it up to do another and for some reason ithe 1st pump for adding new water switches to removing water after 1 cycle. Why are these so finicky?!
