Well it probably needs a new gasket.
It is noisy, like it has air in it but no bubbles appear from the inlets.
When switched to rinse, I could see water rise from the notched area. It's hard to turn.
I read an old thread here and someone had to use wood blocks and a clamp to reassemble theirs.
So I'm looking to avoid any gotcha's.
I've seen the rebuild kits on the net but no instructions.
