Turn off the water
Pop the center out of the knob
Unscrew the screw in the center of the knob and the screws on the chrome
trim piece/cover.
Take off the chrome cover and the knob.
Locate the nut on the diverter and unscrew it.
Clean and delime it
reassemble in reverse order
Turn water back on
Check for leaks
Should now work fine


Agree with all of the above, but before you reassemble, lube it with
plumbers grease. (Available at any good hardware store.)
