There are , potentially a few other options for the outdoor array.
Assuming , you may have a tipping spoon/bucket , when you cleaned it , did you at any point notice it may stick down? Not saying this is your issue, but it does happen, in which case you want to lubricate the mechanism. Also, you should be able to see the results of manually tipping the spoon/bucket a few times on your console ... I would go for 10- 20 push downs and see what you get.
