I honestly can't believe I'm having another problem right now, but...
When I turned my filter setting from filter to backwash it made a strange almost grinding noise for a quick second and then it just felt like it wasn't catching as I turned it. The settings do change to what I've set it for (ie. filter, backwash, rinse) but it just doesn't feel right as I do it. Also, when the back wash was running the output was irregular where the hose would go flat every few seconds.
Is this the spider gasket that causes that, and if so...I know nothing about this part other than the name.
Hoping someone could help me out yet again.
