This Moen kitchen faucet was just installed a few months ago. I opted
for the spray attachment which I find handy. However, recently it
"sticks" - i.e., fails to shut off, so no water from main faucet.
I took it partially apart -- unscrewed the spray head, removed &
replaced the spray button cover, but no change.
Then I banged the spray button cover gently, but no change.
Then I opened the water wide, thinking a jolt might unstick whatever
was causing problem, but no change.
Then I noticed that with water wide open, the spray diverter? if
that's the responsible element? closed by itself after a few minutes,
and water came out of the faucet again.
I don't want to go through this every time I use the sprayer.
Any clues why this is happening and what to do about it?
